The warning is related to the coordinate parameter of blit(). Floating point coordinates, would mean that the origin of the Surface is somewhere in between to pixels in the window. That doesn’t make much sense. The coordinates are automatically, implicitly truncated and that is indicated by the warning. Use either int or round to convert … Read more
The instructions differ if you have a 32-bit proccessor or a 64-bit one. Users of 32-bit processors should just download and install the binary labeled pygame-1.9.1release-python.org-32bit-py2.7-macosx10.3.dmg on the pygame download page. Users of 64-bit processors should follow the instructions below. There is no 64-bit version of pygame for Mac OS X. The 32-bit version of … Read more
Your problem is that you fade in to a black screen, so you don’t see any effect. A black screen with a black half-translucent Surface drawn on top is still a black Surface. You should render the first frame of your level, and blit that Surface to the screen before blitting the fadein surface onto … Read more
Your approach works fine, if the x and y component of the ray axis points in the positive direction, but it fails if it points in the negative direction. As you pointed out, that is caused by the way pygame.mask.Mask.overlap works: Starting at the top left corner it checks bits 0 to W – 1 … Read more
You can use the eval(string) method to do this. Definition eval(code, globals=None, locals=None) The code is just standard Python code – this means that it still needs to be properly indented. The globals can have a custom __builtins__ defined, which could be useful for security purposes. Example eval(“print(‘Hello’)”) Would print hello to the console. You … Read more
pygame uses SDL_ttf for rendering, so you should be in fine shape as rendering goes. unifont.org appears to have some extensive resources on Open-Source fonts for a range of scripts. I grabbed the Cyberbit pan-unicode font and extracted the encluded ttf. The folowing ‘worked on my machine’ which is a Windows Vista Home Basic and … Read more
The clock.tick returns the time since the last call to clock.tick. Use that value and multiply all your speeds with it when you move. Example dt = clock.tick(60) player.position.x += player.xSpeed * dt player.position.y += player.ySpeed * dt This way your player will always move at the same speed independent of what you put into … Read more
You have to erase the old text first. Surfaces created by Font.render are ordinary surfaces. Once a Surface is blit, its contents become part of the destination surface, and you have to manipulate the destination surface to erase whatever was blit from the source surface. One way to erase the destination surface is to blit … Read more
Click events if event.type == pygame.MOUSEBUTTONDOWN: print(event.button) event.button can equal several integer values: 1 – left click 2 – middle click 3 – right click 4 – scroll up 5 – scroll down Fetching mouse state Instead of waiting for an event, you can get the current button state as well: state = pygame.mouse.get_pressed() This … Read more
You can achieve this by 2 steps. self.original_image contains the filled rectangle with the desired color: self.original_image.fill(self.colour) Generate a completely white rectangle and transparent areas. Blend the rectangle with (self.image) and the blend mode BLEND_MAX (see pygame.Surface.blit): whiteTransparent = pg.Surface(self.image.get_size(), pg.SRCALPHA) whiteTransparent.fill((255, 255, 255, 0)) self.image.blit(whiteTransparent, (0, 0), special_flags=pg.BLEND_MAX) Now the rectangle is completely white, … Read more
