Many Stumps in Scripting and Materials

Unity Engine

So basically I want to change the material, (or texture if possible) on my character. (Its a sphere atm - representing a bubble like thing that you control). It has a material on it that has a texture. When I hit a crate I wan’t the material to change to a different one. I’m using Java Script in this game so don’t give me anything in C# or something else.

So in other words, how can I change the material of an object after it hits a collider?
Something like this?

function OnTriggerEnter( hit : Collider )
{
	if(hit.gameObject.tag == "Crate")
	{
		//Change material of object this is on
	}
}

Ok well I ended up taking a bit of time to figure this out myself. This is what I did…

//Meshes for character
var MeshControl = 0;
var Mesh1 : Texture;
var Mesh2 : Texture;
var Mesh3 : Texture;
var Mesh4 : Texture;
var Mesh5 : Texture;
var Mesh6 : Texture;

function Update() 
{
//Meshes Changers
switch(MeshControl)
{
case 0:
renderer.material.mainTexture = Mesh1;
break;
case 1:
renderer.material.mainTexture = Mesh2;
break;
case 2:
renderer.material.mainTexture = Mesh3;
break;
case 3:
renderer.material.mainTexture = Mesh4;
break;
case 4:
renderer.material.mainTexture = Mesh5;
break;
case 5:
renderer.material.mainTexture = Mesh6;
break;

}
}

function OnTriggerEnter( hit : Collider )
{
	if(hit.gameObject.tag == "Crate")
	{
		MeshControl += 1;
	}
}

Use an array of materials instead of discrete variables. Iterate an index of the array and set your material accordingly.

Two lines are always better than 20.

can you show an example

// Warning forum code!

var textureArray : Texture[];
var textureIndex = 0;

function OnTriggerEnter( hit : Collider )
{
	if(hit.gameObject.tag == "Crate")
	{
		ChangeTexture();
	}
}

ChangeTexture() {

textureIndex++;

// Make sure selection is not out of bounds.

if (textureIndex > textureArray.GetUpperBound(0))
 textureIndex = 0;
 
if (textureIndex < 0)
 textureIndex = textureArray.GetUpperBound(0);

renderer.material.mainTexture = textureArray[textureIndex];
}
