 For instance, he went through a lot of work creating collision shapes for each block face and then using that to determine what face the player was looking at. However, I found the following basically removed any need for such complicated collision shapes and code:
 
 ```
-EntityManager.create_block.emit("001", collider.position + get_collision_normal())
+if Input.is_action_just_pressed("right_click_interact"):
+    EntityManager.create_block.emit("001", collider.position + get_collision_normal())
 ```
 
 1 line of code replaced a very large amount of code and changes that were implemented in his `Create Blocks` video.

+I also moved some actions to signals as I prefer this method.
