object not set to instance..........again.

Question

So i have had this issue before, and it has been dealt with in a different scenario, however i can't come to a solution for this one. when i call a function in another script it tells me that it needs to be set to an instance of an object, and im assuming its refering the the "this.transform" part. What's a work around for this?

  else if(!terrain.chunksToRender.Contains(this.transform)) { 
             
             terrain terrainScript = player.GetComponent<terrain>(); 
             terrainScript.renderChunk(this.transform); //here lies the issue
             terrain.chunksToRender.Add(this.transform);
             
         }

Hi,

It must be terrainscript which has a null reference. Are you sure that you have attached the script terrain to your GameObject player ?

If you want to debug, just try something like this :

 terrain terrainScript = player.GetComponent<terrain>(); 
 if( terrainScript == null)
 {
          Debug.Log("terrain script not found");
 }
 else 
 { 
          terrainScript.renderChunk(this.transform);
          terrain.chunksToRender.Add(this.transform);
 }

You should also give your script/class name a name starting with a upper case, it is a C# convention. Here you should have "Terrain" instead of terrain.

Can't you just do "transform" instead of "this.transform"? I don't know if the word "this" is actually used anywhere in Unity.

That still gives me the same "object reference not set to instance" error.

this. is accepted by Unity, just as the keyword new (new Vector3) is accepted in uJS. They are not required, but they work =]

Sorry, I cannot help with your problem in C# though, it is merciless if you don't declare things as it likes :(

unless it's something simple like the method renderChunk is not set as public void?
