To some degree, you can simulate gradients with tinted images. Example:
from scene import * class MyScene (Scene): def draw(self): background(0, 0, 0) fill(0, 0, 1) #blue rect(0, 0, 256, 256) tint(1, 0, 0) #red image('Gradient-1', 0, 0, 256, 256) run(MyScene())There are built-in 256x256 pixel images for different types of gradients ('Gradient-1' ... 'Gradient-5'). The gradients all go from fully-transparent to white, so you can achieve different 2-color gradients by drawing a filled rectangle behind the gradient image (which can be tinted with the second color, as in the example above).
