Note that chess pieces can also be drawn through a Unicode text. How do I blit a PNG with some transparency onto a surface in Pygame?.How can I make an Image with a transparent Backround in Pygame?.Image = pygame.Surface(rect.size).convert_alpha() # <. Or use convert_alpha(): class SpriteSheet: Image = pygame.Surface(rect.size, pygame.SRCALPHA) # <. The initial value of the pixels is (0, 0, 0, 0): my_surface = pygame.Surface((width, height), pygame.SRCALPHA)Īnd adapt the method image_at of the class SpriteSheet. Set the SRCALPHA flag to create a surface with an image format that includes a per-pixel alpha. You can enable additional functions when creating a new surface. If you copy a transparent Surface to another Surface the target Surface has to provide transparency respectively per pixel alpha.

#PYGAME IMAGE CONVERT ALPHA HOW TO#
Please someone help me figure out how to make the pieces show with a transparent background.
gif, tried with the top 5 different images on google. convert_alpha(), tried with neither, tried with. But one thing I know for sure is, you always want to convert() or alpha_convert() all the images you load to improve performance.I have read the top 20 posts relating to this issue here, read many examples on Google, tried using. So, in short, one of the things you can use convert_alpha() for is pixel perfect collision and I'm sure there are many other uses for it but this the one I know that it is useful for, and please take all of this with a grain of salt because I'm just relaying information that I gathered from the internet when I was looking for the answer myself. They will also include some simple but effective. They will do all of the boring, generic tasks like loading modules, loading images, opening networking connections, playing music, and so on. So, when you load an image with convert_alpha(), you can then use it to create a pixel perfect Pygame.mask for the banana, meaning that even if the banana's rectangle (let's say it is 5 pixels wider than the banana) is in collision with another object's rectangle, the alpha mask is technically not colliding as long as the other surface does not touch the banana (also assuming the other surface another alpha masked image). The first sections of code are relatively simple, and, once written, can usually be reused in every game you consequently make. png image of a banana with transparent background, and you use convert_alpha() the image will be transformed into black and white (it still blits it normally), white being the transparent parts that are not part of the image, and the black part being the banana, the actual and only part that should be visible. But, convert_alpha() creates a silhouette, if that makes sense, of a. I'm relatively new to Pygame so if someone more knowledgeable comments, you should probably disregard this one.Īs far as I understand, you can use either convert() or convert_alpha() and they will improve game performance, as they convert the image to draw it faster.
