how do i make my game full screen

use video_switch in your main function

eg

video_switch(7,0,1); makes the display 800x600(7) and fullscreen(1) change the 1 to 2 to take the display back to window mode.

Thanks Man

type

var video_screen=1;

Why

Use var video_screen = 1; if you wish to start the game in fullscreen else exclude it.

You cannot change it at runtime using video_screen and therefore must use video_switch.
