Room height

Explanation
This variable holds the height of the entire room (you need to use to get the size of the view inside the room). This variable is read-only, you cannot use this function to change the size of the room.

Example
// Create an object at the bottom of the room (100,room_height,obj_player); In the example above, as you're using room_height, no matter what size the room is, the object will always be placed at the bottom. You can also use room_hieght to place objects in the middle of the screen. First, make sure the origins of the object is in the center then you divide room_height by 2: // Create and center the object horizontally in the room (100,room_height/2,obj_player);
