position_meeting(x, y, obj);
| Argument | Description |
|---|---|
| x | The x position to check. |
| y | The y position to check. |
| obj | The object (or instance id, or the keywords "all" or "other") to check for a collision with. |
Returns: Boolean
With this function you can check a position for a collision with another instance or all instances of an object. When you use this you are checking a single point in the room for an instance or an
object. This check will be done against the bounding box of the instance or against the mask of the instance if that instance has precise collisions checked. If you need to know get the unique
instance id if the object being collided with you should use instance_position.
This function also accepts the special keywords all and other.
if mouse_check_button(mb_left)
{
if !position_meeting(mouse_x, mouse_y, all) instance_create(mouse_x, mouse_y, obj_Wall);
}
The above code checks for the left mouse button, and if it is pressed it checks the mouse x/y position for a collision with any instance. If there is none, then an instance of "obj_Wall" is created.
