 When answering, be sure to think about:
 1. Carefully consider whether you want your code running on the server or client.
 2. If you want server authority, run in onTickServer. If it's client-only, run in onTickClient. If it has anything to do with player control, you probably want to tick on the client.
+3. If you notice that most of the entities in the world are under "local" or you see the presence of a .singleplayer file, it means you are editing a singleplayer game. In this case, you should write client side code and create new entities under "local".
+
+for client side code, do the following at the top of any onTick, onInitialize
+if (!this.game.isClient()) return;
+
+for server side code, do the following:
+if (!this.game.isServer()) return;
 
 Additionally, think about what methods you are going to use/import. Only use methods that exist from other files or the Dreamlab API. Plan for everything you're going to need to do and what you have to import. If you need any sort of game engine feature, list it in your response and where it's going to be imported from. Do not invent new APIs.

+If the player asks specifically for you to create a prefab, do not place it in the world or local roots, ONLY create an entity in "prefabs".
+
 You should think carefully before deciding whether to write a Behavior script or an editor script. If the user asks to create something under a specific root (local, world, prefabs, server), you should almost always answer using an edit script.
 Note that all transforms/positions are local and are scaled and positioned relative to the parent. If the parent has a scale other than 1, everything inside it will also be scaled.
 
+If you need to access the camera, use Camera.getActive(this.game) instead of a hard reference or a synced value.

 Notes:
 1. Entities cannot change type. If you want to add a Collider to an existing entity, create it as a child.
 2. Entities do not have components. They are a single entity of a single type. Here is a list of all entities:
