How to display a characters "dialogue" when entering a collider?

Question

Hi there.

I've been looking around for quite some time now, but can't seem to find a solution.

I'm trying to solve two different, yet similar problems.

1) When the player gets near an other objects collider, a text will appear in front of that object as its "dialogue" or thoughts, then quickly disappear again. Like this:

alt text

2) Also, when the player enters an invisible collider, I need a text to appear in front of the player and follow him (as in being attached to him). This will work as the players "dialogue" or thoughts and again quickly disappear. Just like this:

alt text

I've beeing digging into these two links, here and here (and many questions similar to this one), but I have little-to-no experience with GUI.

Any help/explanation is appreciated!

Thanks.

create a guiText

Write your Dialogue

position it , attach it to your player and deactivate it

and Attach this script to a box and delete the Mesh Renderer And The Mesh Filter Make the Box Collider Is trigger

 var Dialogue : GUIText;
 function OnTriggerEnter(collider : Collider){
     if(collider.gamebject.tag = "Your Player's Tag"){
      Dialogue.enabled = true;
 }
 }

How do I do this, if I've used a TextMesh instead of GUIText?

The code looks like this:

 #pragma strict
 
 var Dialogue : UnityEngine.TextMesh;
 
 function OnTriggerEnter(collider : Collider)
 {
     if(gameObject.tag=="Player")
     {
      Dialogue.enabled = true;
 }
 }

But I get an error saying: 'enabled' is not a member of 'UnityEnginge.TextMesh'

Try:

  Dialogue.renderer.enabled = true;

Instead

It removed the error. But still, nothing happens. I have the TextMesh as a disabled child to the Player and a Boxcollider with "is trigger" activated, with my DisplayDialogue script attached. The script looks like this:

 #pragma strict
 
 var Dialogue : TextMesh;
 
 function OnTriggerEnter(collider : Collider)
 {
     if(gameObject.tag=="Player")
     {
       Dialogue.renderer.enabled = true;
 }
 }

Any idea what's wrong? Here's a picture showing nothing: alt text

Does your player have a RigidBody attached?

Yes he has. I tried with a debugging and nothing new. But when I removed the if(gameObject.tag =="Player") part, it was able to debug but still not able to activate the object with the TextMesh.

Is the var correctly done?
