Pygame: Draw single pixel

Question

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).

Accepted 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)
```
