Create the animation character on the maze

Today we are going to create the animated enemy for our new pygame project. We are going to edit the enemy manager class and the game manager class then we are going to create an enemy sprite class and an enemy object class which will serve as the original sprite container just like the previous background object class does.

Alright, let us get the thing going. First of all we are going to create the enemy object class which will hold the list which contains the initial enemy object’s position on the maze board for each level.

class EnemyObject(object):

    def __init__(self):

        self.list_1 = [

            [0, 1, 0, 0, 0, 1, 0, 0, 0, 0],
            [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
            [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
            [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
            [0, 0, 0, 0, 1, 0, 0, 0, 1, 0],
            [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
            [0, 0, 0, 0, 0, 0, 1, 0, 0, 0],
            [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
            [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
            [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
        ]

    def get_object_list(self, level):

        if(level == 1):
            return self.list_1

The above class is just like the background object class which you have seen previously.

Next we will create the enemy sprite class which will perform the same job as the background sprite class which is to render the enemy object on the game scene.

from EnemyObject import EnemyObject
from pygame.locals import *
from pygame import math as mt
from GameSprite import GameSprite

class EnemySprite(object):

    def __init__(self, level, scene):

        self.row = 10
        self.column = 10
        self.enemy_image_sprite = 'Asset/right.png'
        self.scene = scene # game scene instance
        self.space = 64 # image width and height

        self.sprite_frame_list = []
        self.count = -1 # frame controller
        self.forward = False # switch to move counter forward or backward

        # the first frame
        self.frame_1_rect = Rect(0, 0, 64, 64)
        self.sprite_frame_1 = GameSprite(self.enemy_image_sprite, self.frame_1_rect)
        self.sprite_frame_1_surface = self.sprite_frame_1.getImage()
        self.sprite_frame_list.append(self.sprite_frame_1_surface)

        # the second frame
        self.frame_2_rect = Rect(64, 0, 64, 64)
        self.sprite_frame_2 = GameSprite(self.enemy_image_sprite, self.frame_2_rect)
        self.sprite_frame_2_surface = self.sprite_frame_2.getImage()
        self.sprite_frame_list.append(self.sprite_frame_2_surface)

        # the third frame
        self.frame_3_rect = Rect(64 * 2, 0, 64, 64)
        self.sprite_frame_3 = GameSprite(self.enemy_image_sprite, self.frame_3_rect)
        self.sprite_frame_3_surface = self.sprite_frame_3.getImage()
        self.sprite_frame_list.append(self.sprite_frame_3_surface)

        # the fourth frame
        self.frame_4_rect = Rect(64 * 3, 0, 64, 64)
        self.sprite_frame_4 = GameSprite(self.enemy_image_sprite, self.frame_4_rect)
        self.sprite_frame_4_surface = self.sprite_frame_4.getImage()
        self.sprite_frame_list.append(self.sprite_frame_4_surface)

        # the fifth frame
        self.frame_5_rect = Rect(64 * 4, 0, 64, 64)
        self.sprite_frame_5 = GameSprite(self.enemy_image_sprite, self.frame_5_rect)
        self.sprite_frame_5_surface = self.sprite_frame_5.getImage()
        self.sprite_frame_list.append(self.sprite_frame_5_surface)

        # the sixth frame
        self.frame_6_rect = Rect(64 * 5, 0, 64, 64)
        self.sprite_frame_6 = GameSprite(self.enemy_image_sprite, self.frame_6_rect)
        self.sprite_frame_6_surface = self.sprite_frame_6.getImage()
        self.sprite_frame_list.append(self.sprite_frame_6_surface)

        # the seventh frame
        self.frame_7_rect = Rect(64 * 6, 0, 64, 64)
        self.sprite_frame_7 = GameSprite(self.enemy_image_sprite, self.frame_7_rect)
        self.sprite_frame_7_surface = self.sprite_frame_7.getImage()
        self.sprite_frame_list.append(self.sprite_frame_7_surface)

        self.level = level # current game level

        self.enemy_object = EnemyObject()

    def draw(self):

        for row in range(self.row):

            for column in range(self.column):

                if (self.count > 6 and self.forward == True):  # use this logic to control the counter and the image
                    self.count -= 1
                    self.forward = False
                elif (self.count < 0 and self.forward == False):
                    self.count += 1
                    self.forward = True
                elif (self.forward == False):
                    self.count -= 1
                elif (self.forward == True):
                    self.count += 1

                self.draw_pos = mt.Vector2(self.space * column, self.space * row) # the position of the image on game scene

                if(self.enemy_list[row][column] == 1):
                    self.scene.blit(self.sprite_frame_list[self.count], self.draw_pos)  # draw enemy frame

    def get_level(self, level):
        self.enemy_list = self.enemy_object.get_object_list(level)

The above class is more complicated than the background sprite class but the idea is the same, which is to render the game’s object on the scene. We will come back to further modify this class in the next chapter but for now this class will just initiate the enemy object on the game scene and then continuously animates the enemy object on each update.

Our next target is to modify the enemy manager class accordingly.

from EnemySprite import EnemySprite

class EnemyManager(object):

    def __init__(self, scene, game_level):

        self.scene = scene
        self.enemy_list = []
        self.level = game_level
        self.enemy = EnemySprite(self.level, self.scene)
        self.create_enemy()

    def create_enemy(self):

        self.enemy.get_level(self.level)

    def update(self):

        pass

    # check the boundary of the enemy with the game scene area
    def check_boundary(self):

        pass

    def draw(self):

        self.enemy.draw()

Then on the game manager class, we will call the enemy manager class to prepare and to draw the enemy object during each game loop.

            pygame.display.flip()

That is it, as we slowly develop our new pygame project we will further edit the above game manager class.

Create the game background Part 2

Hello and welcome back to part two of this chapter. In this chapter, we will finish up the background rendering process for our new pygame project. If you have missed out the first part of the tutorial then you can read it here. OK let us continue…

In part one we have created two new classes, in this part, we will find out how to use them. First of all, you will need to create a tile sheet which you can then use in this new project. Then you will need to download the free tiled map editor through this link and start to create the tiled map for the game’s background by following this youtube tutorial.

Here is a snapshot of the tiled map editor which I have used to create the tiled map for the game background.

http://islandstropicalman.tumblr.com/post/182413408550/tiled-editor
game tile sheet

Before you can use the tiled editor to create a tiled map you will need to create five 64 x 64 pixels images as shown above which will be used as the background images for the game. You can create the above images with free software such as Inkscape, make sure there is no space in between each image, the final size of that image will be 320px x 64px in a straight line.

The tiled program above will generate a number and position for each image using the above tile sheet in the form of a matrix. We then will turn that matrix into a list which consists of many lists and use it to render the background images for the game. That list will be kept under the BgObject class as shown in the previous article.

Finally, in order to render those background images, we only need to modify the game manager class accordingly.

We have stopped updating and rendering the player, enemy and the missile object for a while which we will deal with them later on. Below is the new gaming background.

If you would like to follow me on Twitter or provide your suggestions for this new pygame project kindly do so! See you in the next article!

Create the game background part 1

Hello, and welcome back, starting from today I will definitely use my time effectively which means less Youtubed and Googled around so I can concentrate most of the time on writing article, creating the game and managing my own shoe selling’s business. This year is make money online and offline year for me, wasting time on Youtube or surfing around must be stopped so those time can be used to do more meaningful stuff. Alright, so much for that let us get into the business.

As the title has suggested, in this chapter we will create the game’s background for our new pygame project. As I have mentioned before we are creating a maze game project so you can expect something new as compared to the previous project. Before we start let us look at our strategy to create the background object first.

  1. We will create a container which will hold all those lists that contain the background images for each level.
  2. We will create the background object’s sprite class which will be used to render those background images on the game background.

This chapter consists of two parts, in this first part we will create those two classes above and you will slowly understand what I am doing when we get to the next part.

The BgObject class is the container which will contain all the background images’ lists. At the moment the class only has one list which contains various images.

class BgObject(object):

    def __init__(self):

        self.list_1 = [
            [3, 3, 3, 3, 3, 3, 3, 3, 3, 2],
            [4, 0, 0, 0, 0, 0, 0, 0, 0, 0],
            [4, 3, 3, 3, 3, 3, 3, 3, 3, 3],
            [0, 0, 4, 0, 0, 0, 3, 3, 3, 3],
            [3, 3, 4, 3, 3, 3, 3, 3, 3, 3],
            [0, 0, 0, 0, 1, 4, 1, 0, 0, 1],
            [3, 3, 3, 3, 3, 4, 3, 3, 3, 3],
            [3, 3, 3, 3, 3, 1, 1, 0, 0, 4],
            [3, 3, 3, 3, 3, 3, 3, 3, 3, 4],
            [0, 1, 0, 0, 1, 1, 0, 1, 1, 0]
        ]

    def get_object_list(self, level):

        if(level == 1):
            return self.list_1           

This class above is a container which holds all the background objects. Now let us create the background sprite class which will responsible for the object’s rendering job.

from pygame.locals import *
from BgObject import BgObject
from pygame import math as mt

class BackGroundSprite(object):

    def __init__(self, level, scene):

        self.row = 10
        self.column = 10
        self.bg_image_sprite = 'Asset/tile0.png'
        self.scene = scene # game scene instance
        self.space = 64 # image width and height

        # the road sprite
        self.road_rect = Rect(0, 0, 64, 64)
        self.sprite_road = BgSprite(self.bg_image_sprite, self.road_rect)
        self.road_surface = self.sprite_road.getImage()

        # the grass sprite
        self.grass_rect = Rect(64 * 1, 0, 64, 64)
        self.sprite_grass = BgSprite(self.bg_image_sprite, self.grass_rect)
        self.grass_surface = self.sprite_grass.getImage()

        # the door sprite
        self.door_rect = Rect(64 * 2, 0, 64, 64)
        self.sprite_door = BgSprite(self.bg_image_sprite, self.door_rect)
        self.door_surface = self.sprite_door.getImage()

        # the air sprite
        self.air_rect = Rect(64 * 3, 0, 64, 64)
        self.sprite_air = BgSprite(self.bg_image_sprite, self.air_rect)
        self.air_surface = self.sprite_air.getImage()

        # the ladder sprite
        self.ladder_rect = Rect(64 * 4, 0, 64, 64)
        self.sprite_ladder = BgSprite(self.bg_image_sprite, self.ladder_rect)
        self.ladder_surface = self.sprite_ladder.getImage()

        self.level = level # current game level

        self.bg_object = BgObject()

        self.get_level(self.level)

    def draw(self):

        for row in range(self.row):

            for column in range(self.column):

                self.draw_pos = mt.Vector2(self.space * column, self.space * row) # the position of the image on game scene

                if(self.bg_list[row][column] == 0):
                    self.scene.blit(self.road_surface, self.draw_pos)  # draw road
                elif (self.bg_list[row][column] == 1):
                    self.scene.blit(self.grass_surface, self.draw_pos)  # draw grass
                elif (self.bg_list[row][column] == 2):
                    self.scene.blit(self.door_surface, self.draw_pos)  # draw door
                elif (self.bg_list[row][column] == 3):
                    self.scene.blit(self.air_surface, self.draw_pos)  # draw air
                elif (self.bg_list[row][column] == 4):
                    self.scene.blit(self.ladder_surface, self.draw_pos)  # draw ladder

        #pygame.display.flip()

    def get_level(self, level):
        self.bg_list = self.bg_object.get_object_list(level)

The game scene is consists of 10 rows 10 columns. If you are still confused with what the above classes do then you will see what I am up to when we go further down the road. Alright, so much for that, we will continue to develop the background rendering engine on the next part of this chapter, stay tuned!

Create an animated game object in Pygame project

Hello and nice to be back, it has been a while I am not writing any article on this site but I promise you that you will see more articles in the future. As I had promised you before I will create two game projects at the same time, a Panda 3D game and a new Pygame project. Both will start at the same time. This article is about the new Pygame project. In this article we will make a slight modification on the Start Scene class which we have created a while ago, we will replace the stand still human with an animated humanoid at the main menu page area by editing some part of the code on the Start Scene class.

In the above program, we have created a counter which will change the location of the rectangle used to map the game sprite and thus created an animation effect.

After a few days of rest, we will start to create our new Pygame project, if you have not yet subscribed to this website, you can do so by clicking on the red bell button on the side of this article.

Have you already downloaded mine previous pygame project? If not here it is.

More goodies to come so stay tuned.

Render game scene with Panda 3D

Today we will continue to explore Panda 3D, after a day of searching online for the method to export the whole mesh created with Blender which can then be used in Panda 3D’s game I have found two of them. 1) Exporting the mesh in the Direct (x) format 2) Using YABEE to export the mesh in the egg file format. I have tried both and the result is still the same, the mesh has been rendered on the game scene but without any texture on it. What could have possibly gone wrong? Maybe if I light up the game scene then the texture will appear? I have not decided yet whether do I want to use Panda 3D or another game engine to create the next python 3D game.

Anyway, Panda 3D has it’s own game graphic so if we use it’s game graphic instead then there is no problem rendering the graphic on the scene.

This is the program on their website which will render the game graphic on the game scene.

from direct.showbase.ShowBase import ShowBase
 
class MyApp(ShowBase):
 
    def __init__(self):
        ShowBase.__init__(self)
 
        # Load the environment model.
        self.scene = self.loader.loadModel("models/environment")
        # Reparent the model to render.
        self.scene.reparentTo(self.render)
        # Apply scale and position transforms on the model.
        self.scene.setScale(1.5, 1.5, 1.5)
        self.scene.setPos(3, 42, 0)
 
app = MyApp()
app.run()

You will see below scene if you run the above program.

I am working on the other pygame project besides trying out Panda 3D and in the next chapter we will continue to develop that other pygame project since there is no further breakthrough in this Panda 3D game graphic stuff, if you know the method to export the mesh together with texture in Blender do let me know about it. Thank in advance.

The starting of new pygame project

Hello, welcome back, due to busy managing the offline business as well as writing article for another website, therefore, no post had been created in the past few days. Today we will finally begin the first chapter of our new pygame project which will go on for a while so do visit this site once in a while for more articles.

After we have created the first pygame project we already have the full python’s game framework which we can use to create the second game. All I am doing now is to reuse most of the classes that I have created in the previous project and will only do the necessary modification on those classes when we need to. What our game plan for this game is to start from the menu page and then slowly moving down to the game manager class and so on. The thing we need to do in this article is to modify the main menu page of the previous game. Before we do anything we will change the name of the main file from hello.py to main.py plus change the title of the game, we will also change the name of the color manager class to something meaningful and change the default color which that color class will receive.

            # 1 is the left mouse button

Finally, we will replace the previous graphic on the main menu page with the new one as well as changing the background color. All the other features remain unchanged.

With those small changes we have finished the main page setup, it seems like there is nothing much to change on those other pages so in the next article we will start to modify those game object classes.

The Amaze Boy main page

At the moment I am using the below soundtrack for this new game, but I will come out with totally new music. If you are also a music lover then do follow me on SoundCloud so we can listen to each other music together!

Still around, ok here is another announcement which I want to make. I will change the game plan a little, the original plan of creating five games with pygame will now reduce to only three games, I will create another 2 games with other python gaming framework which will definitely help me as well as you to get used to other python gaming framework instead of just pygame. The new game which will be developed with another framework will start together with this latest pygame project so do subscribe to this website immediately through the red bell button on this page if you are really serious about learning python as well as creating your own game with python.

The new version of AirStrike

Finally, I have released the latest version of AirStrike today, you can download this version directly through the below widget.

In this version, the highest level still remains at level three but there are lots of changes have been made on the previous version, particularly on the movement part of the horizontal moving enemy ship which I had mentioned before in the previous post. Besides that, I have also found out that the game level which has been saved during the game will not get reloaded in the previous version of the game because of the unknown reason which I am still trying to figure it out, so temporary the entire game will be included in a zip file, after you have unzipped the game, you will find a hello folder which contains all the game files and a hello application file, right click on that hello application file will start the game. If it is your first time running the game on windows 10 then you will see a pop up window asking whether you want to continue running the game or not, just click on the’ more’ link then select run anyway to start the game. This game is currently only for the Windows 10 user but it might also for Linux and OSX user in the future.

I am working on the next level of the game and hopefully, pretty soon a new version will be released on the major gaming website. If you have any question regarding the game do leave your comment on the comment box below.

Show the game level on game scene

Hello, it has been a day since the last post, I am busy preparing the next pygame project which will appear on this website soon so do stay tuned. While we are getting ready for our next game project in a few days time why don’t we look at what are those changes that we have made on the previous pygame project in this article? While preparing the second released for the previous pygame project I have made another update on the game scene by including the level text on top of the game scene. The new game scene will look like this, the score text on the left and the level text on the center.

The new game scene

In order to include the level text, we have made the changes on both the game manager class as well as the score class.

The second version of this game is actually ready, I am playing it now to make sure there is no bug in this game before uploading the game. If you have not yet downloaded the first version of the game you can do so through below link.

A sneak preview at the next python pygame project

Hello, it is nice to be back again. After the final touch up of the previous pygame project, we are now ready to start the next pygame project. We will continue to develop that previous pygame project but our attention now is on this new project.

Yesterday I had received a comment from a fan on the main page of our previous pygame project which stated that there are not many people using pygame framework to develop the python game, my first thought was what is he talking about, man? There are lots of people actually using pygame framework to develop great commercial games and have received great success from it. If you search around the internet you will soon find out that pygame is indeed the best python framework which we can use to develop the 2d game both for free and for sale!

OK back to the topic of this article. Today I am going to provide you with a quick summary of the new pygame project which I will develop later on. This game will consist of 10 levels. It is about the story of a boy who will walk through all the obstacles from one side to another to reach the exit and then proceeds to the next level. The game characters will consist of a boy, robots and also the life-saving mana. This is a maze game where the boy will move from top to bottom or from the bottom to the top through ladders. The most important thing in this game is to not get hit by a robot or else it will be game over. Below is the sneak preview of the game.

Boy and Robot

There are some of you might have already played this game online before but believe me, this is a totally new game with a new storyline.

Hopefully you can read a new chapter on this game everyday, if not then at least once every three days. Besides developing game, I also need to take care of the offline business but I promise to write as many articles as possible on each week, so stay tuned.

Increase the speed of the enemy ship

Hello friend, I wish you all have a nice day. After near to a month of continuing to develop this latest pygame project, today I have finally completely finished all three stages of the game and fixed most of the bugs that I can find during gameplay. Today I will put forward the last piece of code that will speed up the enemy ship a little bit during the game by changing the vertical speed of the enemy ship during the game. Only one file is involved in this process which is the enemy manager class file.

With that last piece of code in place now we will be ready to move on to the next stage of the game. As you can see the first three levels of the game are fairly easy and simple but when we move beyond that the game will become very hard because I will include more enemies and more obstacles during the game stage that will make it very hard for a player to win that stage. If you have not yet downloaded the earliest version of this game yet you can do so through below widgets, those latest updates will show up in the next update so stay tuned.
