is_mouse_over_debug_overlay

This function returns true if the mouse is over a debug overlay window or gadget, or is being used by the debug overlay in any other way (i.e. when dragging windows).

The mouse is over The Debug Overlay whenever it's over a menu or window.

Syntax:

is_mouse_over_debug_overlay();

Returns:

Boolean

Example:

Step Event

if (!is_mouse_over_debug_overlay())
{
    if (keyboard_check_pressed(vk_control))
    {
        instance_create_layer(mouse_x, mouse_y, layer, obj_enemy);
    }
}

The code example above first uses is_mouse_over_debug_overlay to check if the mouse is over any menu or window of The Debug Overlay. If it's not, keyboard_check_pressed is used to check if the Ctrl key was pressed. If that's the case, an instance of an object obj_enemy is created at the mouse position.
