Replace gameobject with another

Hi,
I've a javascript on a button. This button should be able to replace a gameObject:
1. how can I hide a gameObject (3D Model) from the start, and make it later visible by a buttonclick ?
2. how can I replace this model again by a further buttonclick to another gameObject ?

I would be really grateful if you can help me.
My version is Unity3D 5.0

Best Regards,
Dave

 

Should try asking doctor google first, most problems have been asked and answered already out there:

Hope that helps

 

Yes I used google but i guess my programming skills are to bad and I hope that u can give my some help. I tried your link but unfortunately it doesnt work hope somebody could help me.
This java script runs on a button, but how do the function know which gameObject
is meant I tried for example:

function Change () {

gameObject.GetComponent("tankTwo");
public var rend: gameObject.GetComponent("tankTwo");
function Start() {
rend = GetComponent.<"tankTwo">();
rend.enabled = false;
}

}__________________

#pragma strict
function Update() {

if (Input.GetKeyDown(KeyCode.Z)) {
// show
renderer.enabled = true;
}

if (Input.GetKeyDown(KeyCode.X)) {
// hide
renderer.enabled = false;
}

}

 

I really do recommend looking at the basic scripting tutorials in the learn section...

http://unity3d.com/learn/tutorials/modules/beginner/scripting

you're making some very simple mistakes which you should be able to find and sort out once you have gone through the basics.


also, when you paste code into the forums please use [ code] [/ code] tags, it helps with the readability, there is a sticky on them at the top of the scripting forum.
