Mesh Renderer Script

Im new to this, especially the scripting. I need a script that works out the distance between an object and the main camera and then turns on or of the mesh renderer of that object, as a form of streaming media. I have been using uniLOD but it doesnt support objects with multiple materials. Any help?

 

You can get the distance between two objects with Vector3.Distance:-

Code (csharp):

1. var distance = Vector3.Distance(obj1.transform.position, obj2.transform.position);
2.  
3. if (distance > threshold) {
4.   obj2.renderer.enabled = false;
5. }

 

Thanks but i cant add script to object, "script has not finished compilation".
3 errors i get in the console are:
-An instance of type 'UnityEngine.Component' is required to access non static member 'transform'.
- 'transform' is not a member of 'String'.
- 'renderer' is not a member of 'String'.

Code (csharp):

1. var distance = Vector3.Distance(Camera.transform.position, "Pub_Main".transform.position);
2.  
3. if (distance > 30) {
4.   "Pub_Main".renderer.enabled = false;
5. }
6.  

Please help, again thanks.

 

You can't grab your game objects imply by using a string that way:

Code (csharp):

1. var target = GameObject.Find("Pub_Main");
2.  
3. var distance = Vector3.Distance(Camera.transform.position, target.transform.position);
4.  
5. if (distance > 30)
6. {
7.     target.renderer.enabled = false;
8. }

 

Thanks that fixes all but the first error. hmmm :?

 

Camera.main.transform.position

 

sorry guys but yet another error has occured.
"UnityException: You are not allowed to call this function when declaring a variable.
Move it to the line after without a variable declaration.
If you are using C# don't use this function in the constructor or field initializers, Instead move initialization to the Awake or Start function."

An explaination to the solution would also help so i can avoid the problem in the future... Thanks

 

Would I be right in thinking you have added the posted code directly into a script file? It was just intended as an example of the basic code structure required - you actually need to put this code inside the Update function for it to work correctly. You probably want something like this:-

Code (csharp):

1. var target: GameObject;
2.  
3. function Start() {
4.   var target = GameObject.Find("Pub_Main");
5. }
6.  
7. function Update() {
8.   var distance = Vector3.Distance(Camera.transform.position, target.transform.position);
9.  
10.   if (distance > 30)
11.   {
12.      target.renderer.enabled = false;
13.   }
14. }

 

Thanks guys finally got the script working... And learned a few things in the process... If anyone wants the final script here it is...

Code (csharp):

1. var target: GameObject;
2.  
3. function Start() {
4.   var target = GameObject.Find("Pub_Main");
5. }
6.  
7. function Update() {
8.   var distance = Vector3.Distance(Camera.main.transform.position, target.transform.position);
9.  
10.   if (distance > 50)
11.   {
12.      target.renderer.enabled = false;
13.   }
14.  
15.     if (distance <50)
16.   {
17.      target.renderer.enabled = true;
18.   }
19.  
20. }

One last thing in order to make this script for general use not just for "Pub_main", I would like to make the distances editable within Unity inspector, target already is.
Again Thanks.
