I'm looking for method that allow me to draw single pixel on display screen. For example when I click mouse, I want the position of clicked pixel to change color. I know how to read mouse pos, but I could not find simple pixel draw ( there is screen.fill method but it's not working as I want).
Answer
You can do this with surface.set_at():
surface.set_at((x, y), color)
You can also use pygame.gfxdraw.pixel():
from pygame import gfxdraw
gfxdraw.pixel(surface, x, y, color)
Do note, however, the warning:
EXPERIMENTAL!: meaning this api may change, or dissapear in later pygame releases. If you use this, your code will break with the next pygame release.
You could use surface.fill() to do the job too:
def pixel(surface, color, pos):
surface.fill(color, (pos, (1, 1)))
You can also simply draw a line with the start and end points as the same:
def pixel(surface, color, pos):
pygame.draw.line(surface, color, pos, pos)
