draw_set_alpha(alpha);
| Argument | Description |
|---|---|
| alpha | The alpha to set (between 0 and 1) |
Returns: N/A
With this function you can set the base draw alpha for the game.
This value can be set from 0 to 1 with 0 being fully transparent
and 1 being fully opaque (the default value), and will affect all
further drawing, including backgrounds, sprites, fonts, primitives
and 3D. If any of those assets are drawn with their own alpha value
changed, this will be added to the base alpha value set by this
function, so a base alpha of 0.5 and a sprite being drawn with an
alpha of 0.5 will actually draw the sprite with an alpha of
0.25.
draw_set_alpha(0.5);
draw_set_colour(c_black);
draw_text(x+5, y+5, "LEVEL 1");
draw_set_alpha(1);
draw_set_colour(c_white);
draw_text(x, y, "LEVEL 1");
The above code will draw some text at the specified position with a shadow effect created by modified draw alpha and colour.
