Unity 3 Beta - Trouble converting script over

[petey]

Hi there,

I’m just having a little trouble converting a project over to unity 3, for some reason this bit of code doesn’t seem to work -

if (LeftButtonObj.collider.Raycast (ray, Hit, 100)
Unity gets the error -
MissingMethodException: Method not found: ‘UnityEngine.MeshCollider.Raycast’.

It’s weird because it worked fine before.

Any ideas?
Thanks
Pete

Use Physics.Raycast

Damn. I tried adding #pragma strict but it had no effect.
I think it might be because I am using a mesh collider but I’m not sure.
I’m also not sure that I want to shift it to Physics.Raycast as collider Raycast seemed to nicely limit it to this one collider. Which allowed me to control it a little more.

Also seems kinda frustrating seeing it was already working fine :roll:

Also the example in help seems to be what I have in my script… Hmm not sure.

Oh no, I figure something out but it seems a little buggy, it seems that it only works when it’s in Update, which is a bummer because I pulled it out of update to optimise…

Anyway I whipped up this script that demonstrates the issue, if anyone has a sec, maybe check it out.

#pragma strict

//Choose an object to be the raycast test object “Test Object”
//Check the “TestInsideUpdate” boolean to see it working inside Update
//Uncheck to run through a function (where it doesn’t work)

var TestObject : GameObject;//The object to test with
var TestInsideUpdate : boolean;//Check this to test with Update, Uncheck to test co - routine

function Start(){
if (TestInsideUpdate == false){
RayTest();
print (“Testing as coroutine”);
}
}

function RayTest(){
var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
while (TestInsideUpdate == false){
if (TestObject.collider.Raycast (ray, hit, 100.0)) {
Debug.DrawLine (ray.origin, hit.point);
}
yield;
}
}

function Update(){
var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
if (TestInsideUpdate == true){
if (TestObject.collider.Raycast (ray, hit, 100.0)) {
Debug.DrawLine (ray.origin, hit.point);
}
}
}
