sdl2.draw_point(x, y)

Draws a single pixel at the specified coordinates.

Parameters:

• x (number) - X coordinate
• y (number) - Y coordinate

Returns: null

Example:

sdl2.set_draw_color(255, 255, 255);
sdl2.draw_point(100, 100);

sdl2.draw_line(x1, y1, x2, y2)

Draws a line from point (x1, y1) to point (x2, y2).

Parameters:

• x1 (number) - Starting X coordinate
