The following image is a schematic representation of how layers are rendered to help you visualise what's going on: In our tutorial game, we have just set the bullet instances to use the same layer that the instance of "obj_player" is assigned to by using the layer name "Instances" from the room editor. The page you start on is the . Now that we have our idea, its time to move on to the actual GameMaker Studio 2 Tutorial. Now set the action as follows: Note that when using an object index like this, if there are more than one instance of the object in the room when the code is run it will run for all instances of the object. This is done using the following actions, which you should add in after the current ones: The next thing to do is to make the "hp" variable actually go down, as currently that check will always return false since we only set the "hp" to 5 and nothing else. Edit Image There are a lot of options here, but the first thing we need to do is switch the view "on". You can also set the Horizontal Speedand Vertical Speedfor the background layer. With a simple idea in mind, its time to GameMaker Studio 2 Tutorial: A Simple 5 Step Guide to GMS 2 Now that our object has a gorgeous new stand in graphic to display, go to the room tab, then drag and drop We are going to place this action into the enemy object obj_enemy, specifically in the Step Event, just before we destroy the instance. instead of Right now, unfortunately, our player object looks like nothing. we'll expand on what you've learned here by adding bullets and other world items into our Arena Shooter game. Debugging is no fun, so try to copy the code exactly. We have set the direction so now we use this action to set the speed to 16, which means it will move 16 pixels in the given direction every game frame. We have our enemy spawn object now, but we don't have anything to re-spawn the enemies when there are none left, so for that we are going to create a controller object called obj_spawner. The actions will be like this: Let's just go through the actions here one at a time so you can see what is happening: So, if there is an instance of the player, we then tell the enemy to move at the speed of the "spd" variable towards it.
