Line Renderer Newbie

Unity Engine
1

Can anybody give a example on the ussage of the LineRenderer which would get me started. Ifound this from liquidgraph

/ the options
var startWidth = 0.05;
var endWidth = 0.05;
var aMaterial : Material;


// these are set in start
private var line : LineRenderer;

private var point01 = Vector3(0,0,0);
private var point02 = Vector3(0,0,0);
private var point03 = Vector3(0,0,0);
private var point04 = Vector3(0,0,0);
private var point05 = Vector3(0,0,0);



function Start ()
{
   line = this.gameObject.AddComponent(LineRenderer);
   line.SetWidth(startWidth, endWidth);
   line.SetVertexCount(5);
   line.material = aMaterial;
   line.renderer.enabled = true;
}

function Update ()
{
   line.SetPosition(0, point01);
   line.SetPosition(1, point02);
   line.SetPosition(2, point03);
   line.SetPosition(3, point04);
   line.SetPosition(4, point05);
}

it’s setting four points ergo drawing a retangle.

How can i use the coordinates from other (moving) objects and give them to the line renderer ???
And can the line be not straith, can it be a curve ?

Thanks for any Help or Ideas

you can add the moving objects as Transform variables, and in each update you can change the point0X for the TransformX position, that would add lines between each object in that code
good luck

no, but it is possible to approximate a curve by drawing a lot of shorter line
