This is because objects are instantiated and spawned server side, but on the client side the instantiation of objects is in response to received network messages instead of in a place where object references can be directly cached from the appropriate script. I have some use of tags on the client side of my networked game to establish references between objects. Though I often go back through my code later and set inspector references instead.
Unity forum code tags windows#
My various UI windows sometimes need references to scripts on other UI windows, so I have a base UI object with references that branch out to every other UI window which I just tag with UI for an easy FindWithTag if needed. If it hit a Ship tagged object I do something to the ship, otherwise I don't. In OnCollisionEnter using CompareTag I check what kind of object a projectile hits. So, if you're having performance issues due to needing to find and act on lots of stuff in the scene, you might consider Hybrid ECS as an approach. It turns out that this is fairly similar (I believe) to the approach that Hybrid ECS uses to track things performantly in the scene. The name can be changed to anything you like. You know that there's GameObject.Find which can be used to search for the gameobject's name. If every object should have it's own tag, i don't see why you not just use the name instead of a tag. Then my code can iterate over the arrays in my tracking service rather than finding the objects through Unity's methods. Tags are usually used to group similar objects or to identify (tag) it as part of that group. Tags must be declared in the Tags and Layers manager before using them. Instead, for each object I need to track in this way, I add a component that causes it to register itself with a singleton tracking service on Awake, and to unregister itself on destroy. A tag can be used to identify a game object. Using approaches like FindGameObjectsWithTag or FindObjectsOfType is much too slow for that. But I try to avoid that if possible.Īs for your other question of "finding" stuff in your scene, I have various use cases where I need to act on all the stuff in the scene every frame, or every fixed update. Occasionally I'll check the tags when doing some raycast in cases where the limited number of layers prevents me from being able to have a dedicated layer for all combinations of traits.Similarly, for bullet impact sounds and decals, the surface type a bullet hits determines what kind of sound and decal to use.I went with tags for this, instead of layers, because there is a lot more variety of surface types than layers would support. As of 2016 it is the most widely-used game development system. Unity is a game engine, IDE and service suite developed by Unity Technologies. Each tag maps back to a "surface type" that determines what kinds of sounds to play.

I play different footstep sounds when the player is walking depending on what he's walking on.The ForEach is commented out because I can't get it to to work, but the biggest problems seems to be that the count is always 0. However when I run the code, I always get a count length of 0. I'm trying to read a json data file containing a simple array stored on the Application.dataPath.
