draw_get_alpha

This function returns the current value of the draw alpha, which will range between 0 (fully transparent) and 1 (fully opaque). The draw alpha affects the transparency of all draw functions, and can be set with the draw_set_alpha() function.

Syntax:

draw_get_alpha()

Returns:

Real

Example:

var _cur_alpha = draw_get_alpha();
draw_set_alpha(text_alpha);
draw_text(x, y, text);
draw_set_alpha(_cur_alpha);

The above code stores the current draw alpha into a local variable, and changes the draw alpha based on an instance variable. After drawing some text, it resets the alpha back to the value stored in the local variable.
