WAIT. I missed that...
======== How to use the mouse ========
// Try to cache the return of .get_mouse() as much as you can
var mouse = my_crt.get_mouse();
if mouse.valid {
draw_circle_color(mouse.x, mouse.y, 16, c_blue, c_lime, false);
draw_text(mouse.x, mouse.y, string(mouse.view_index));
}
But for some reason, I had too find multipliers that I still don't know how they work (was trial & error)
var mouse = crt.get_mouse();
if mouse.valid {
mousex = mouse.x * 2.99;
mousey = mouse.y * 2;
}
