Objects INVISIBLE until I pass thru TRIGGER... HOW? I have scripts, but not doing it

FIRST OFF ...... How do I get a Photo up here??? want to show my settings and script.
I went down page to "Manage Attachments" and did not show any way to bring in .jpg picture.

ALSO....Isn't there a way to show the code in a box up here, not as plain text style??

 

There is a sticky post here: http://forum.unity3d.com/threads/143875-Using-code-tags-properly that explains how to use the code tags to format your code.

As for the images, the "From Computer" tab seems to be missing the okay/cancel button. Try using imgur.com and upload there, use the "From URL" tab and paste the imgur link in there.

 

when replying to this thread, click the "Go advanced" button. This is the same text editor as when starting a new thread (almost). There are small icons to attach links, images, video's and code blocks (the code block is the # icon).

 

Ok I see the "Go Advanced" when I press the Reply arrow under somebody's response. Did that.
Now for Photo...

notice I have the mesh boxes checked, but only for me too see the item while taking photo. When I get back in game build mode, I uncheck the Mesh boxes and the Object "step" is Invisible.
But , during RUN mode, when I pass into the Trigger Zone for the Object, the Object (step) does not appear.

 

Code (csharp):

1. #pragma strict
2.  
3. function Start () {
4.  
5. }
6.  
7. var myMeshRenderer:MeshRenderer;
8.  
9. var RenderMesh:boolean = true;
10. // gives toggle box on the object containing the mesh
11.  
12. function Update () {
13.  
14.  if(RenderMesh)
15.   {
16.   myMeshRenderer.enabled = true;
17.   }
18.  
19.  
20.   if(!RenderMesh)
21.   {
22.   myMeshRenderer.enabled = false;
23.   }
24.  
25. }

 

The Large outer box around step is, of course, the Trigger and the smaller box is the Collider to keep player from falling thru.
The idea is to step on the 1st step and the 2nd appears. Jump to it and the 3rd appears, etc., etc.

 

OK Been looking at code. I need a Collider code that tells the Mesh Render to go to TRUE if the Player comes in contact with the Trigger Zone.

Am I on the right track???
I do not want to stick with JS. Would like to make these things C#. So would like comments with codes in C#.

 

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public MeshRenderer;
5. public class Invisibility : MonoBehaviour {
6.        
7.     void OnTriggerEnter(Collider col){
8.      if (col.gameObject.tag == "Player"){
9.         }
10.     GetComponent(MeshRenderer).enabled = true;
11.     }  
12.        
13. }

This did not work

4:20 Parsing error

I tried putting in "public MeshRenderer;" above the Behavior class, but that came up error Have a RED Line under it.
I thought I could declare a variable without having to note a value.

 

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Invisibility : MonoBehaviour {
5.     public Rigidbody SteppingStone9;
6.    
7.     void OnTriggerEnter(Collider col){
8.      if (col.gameObject.tag == "Player"){
9.         Rigidbody Step = Instantiate(SteppingStone9, transform.position, transform.rotation) as Rigidbody;
10.     }  
11.        
12. }
13. }

No ERRORS, but shouldn't I have a few boxes somewhere to fill in for the Position and Rotation I want???

This STEP should appear near the ground attached to the CLIFF WALL near the Antelope in this scene

 

Got it this works perfectly.........

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class StepInvisibility : MonoBehaviour {
5.     void Start(){
6.         Transform step = transform.Find("Step");
7.             step.gameObject.SetActive(false);
8.     }
9.     void OnTriggerEnter(Collider col){
10.      if (col.gameObject.tag == "Player"){
11.         Transform step = transform.Find("Step");
12.             step.gameObject.SetActive(true);
13.  
14.        }
15.     }
16.     /*  
17.      Make an EMPTY creation and place a Collider around it and
18.       designate it as a TRIGGER  Assign this script to the Empty
19.      The gameObject is a model of an fbx model designated as a step
20.      Make the Step a "Child" of the Empty object
21.      When your level(game) starts, the Step is NOT there. Is not Active.
22.      Once the Player makes contact with the Trigger around the Empty,
23.       the Step appears
24.      and you can step on it now. (Is Active now)
25.       This can be done to ANY OBJECTS in GAME
26.  */
27. }

 

Solved

 

Glad you got it solved. btw... to get the meshrenderer use: GetComponent<MeshRenderer>() not GetComponent(MeshRenderer). The difference is:

If you just disable the meshrenderer, your object will be invisible but Update and FixedUpdate will still be executed on scripts attached to your object. If you use SetActive(false), the object will also be invisible... your triggers will still work, but your Update and FixedUpdate methods will not fire. Just something to keep in mind.. if you still need your object to update while it's invisible disable the meshrenderer, otherwise do what you did (using SetActive(false) to disable the object).

 

Thank you, that may come in handy for something else I been thinking of. These steps need no Updates, but maybe the GetComponent<MeshRenderer>() will work for another object.

This code will be like :


using UnityEngine;

using System.Collections;

public MeshRenderer;

public class Invisibility : MonoBehaviour ;


void OnTriggerEnter(Collider col){


if (col.gameObject.tag == "Player"){

}


GetComponent<MeshRenderer>() enabled = true;

}
}


Is that correct??
