Make raycast not hit trigger colliders?

Unity Engine
1

I have a script that functions as a bullet hole generator for my gun. Here’s the code…

var bullethole : GameObject[];
var loaded : GameObject;
var gun : GameObject;


function Start () {

}

function Update () {

    var fwd = transform.TransformDirection(Vector3.forward);
    var hit : RaycastHit;

    if(Input.GetButtonDown("Use") && Physics.Raycast(transform.position, fwd, hit, 999))
        if(loaded.activeSelf)
            if(gun.activeSelf)

    {
        Instantiate(bullethole[Random.Range(0,0)], hit.point, Quaternion.FromToRotation(Vector3.up, hit.normal));
    }

 

      
}

but, the bullet holes sill hit colliders marked as triggers, and it makes it look like the bullet holes are floating in mid air. How do I fix this?

I’m not a pro, so I’m sorry if this is not what you are looking for, but I avoid collision of my projectiles by swapping my layers for my projectile and ignoring any collisions that are on the same layer.
Set layers using EDIT->PROJECT SETTINGS->TAGS AND LAYERS. I also setup the collision matrix with EDIT->PROJECT SETTINGS->PHYSICS. Hope that helps?

You could put your colliers in an child gameobject and put it in a layer which ignores raycasts.

There is a toggle for ‘Raycasts hit triggers’. I believe it’s in the physics settings.

Pass your raycast a QueryTriggerInteraction, which excludes hitting triggers.
