GAMEMAKER STUDIO 2 COLLISION CODE
The above code will check for a collision with instances of "obj_Enemy" and if there is one, it will reduce the "hp" variable by the amount stored in the colliding instance's "dmg" variable and then destroy the colliding instance. For example, the bounding box for a 16×16 collision mask would be generated from (0. Its here Were very proud to officially announce GameMaker Studio 2, the next evolution of our flagship game development tool. The old system used exclusive and rounded coordinates for bounding boxes. Find all you need to know about GameMaker and get inspired to make your own game here. It fixes some issues while breaking lots of things that were working just fine with the previous one. Var _inst = instance_place(x, y, obj_Enemy) The new 2022.1 GameMaker Studio version introduced a new Collision Detection system. This function also accepts the special keywords all and other and will return the keyword noone if no collision occurs, or the unique instance ID value of the instance found if a collision does occur. This function will return the unique instance id of the object being collided, but if that is not needed it is slightly faster to use the function place_meeting(). This will work for precise collisions, but only if both the instance and the object being checked for have precise collision masks selected otherwise only bounding box collisions are applied. When you use this you are effectively asking GameMaker to move the instance to the new position, check for a collision, move back and tell you if a collision was found or not. With this function you can check a position for a collision with another instance or all instances of an object using the collision mask of the instance that runs the code for the check.
