Today I have paid a visit to the Pygame document page to revise all the pygame classes one by one because I have already forgotten all of them. In order to create a game with Pygame I will need to get familiar with these classes again. In this article I will write a simple python class which extends the pygame.Color class to demonstrate the use of the pygame Color class. Since most of the time our game will deal with graphic instead of color we do not actually need this class that much but it is good to go through it so we will get familiar with it if we really need to use it later on.
As usual, I open up the PyCharm which is the official ide for my pygame development project to continue with the previously created game project. I am not going to repeat the PyCharm feature which I have already mentioned in my previous article so if you do miss out my previous article then you can read the first chapter of this pygame development project here (Setting up PyCharm for Pygame development in Windows 10 OS). I also assume you are familiar with python because before you can create a game with pygame you will need to have a very strong python programming background.
Now lets create the extension of the Color class, we will create a new python file, make sure you are clicking on the project folder then goto File->New->Python File and give it any name you wish to.
This will be the class which will extend the Pygame Color class, the good thing we create an extension of the Color class is that we can now add in more custom made functions into this class later on if we need it.
Here is our new AirStrikeColor class.
from pygame import Color class AirStrikeColor(Color): def __init__(self, r=255, g= 255, b= 255, a=255): Color.__init__(self, r, g, b ,a)
As you can see we have created a default value for all four elements (red, green, blue and alpha) so if the programmer does not enter any value when creating the AirStrikeColor class then this new object will use the default values instead.
Alright, that is about it, we will visit this class again to add in more functions if we need it but for now we can use all the functions of the pygame.Color class in our project as usual.
Next step is to import this new class into the main python file I have created previously. We will now go back to the main python file and import the new class.
from AirStrikeColor import AirStrikeColor #from AirStrikeColor.py import AirStrikeColor class
Also we need to take out the
from pygame import Color
statement because we do not need the main Color class anymore.
Now as usual we will replace the Color class statement with AirStrikeColor class statement like this.
Run the program again and it works!
Now replace the statement above with own values.
screen.fill(AirStrikeColor(120, 150, 130, 255).correct_gamma(0.5))
With that we have concluded this second chapter of our pygame development journal and will now getting ready for the third one.
