Best practice to teleport an object

Not sure what’s different for you honestly. Except the local position teleport argument

43

What I am looking for is transform.forward which is SUPER useful in this position…

    update(): void {
        let rotation = getWorldRotation(this.gameObject);
        Gizmos.DrawLine(this.gameObject.position, rotation.normalize().add(this.gameObject.position));
    }

any idea how to fix it? Haven’t dealt with vector mathematics since the University haha

I am trying to draw a line from transofrm.position to transform.forward

45

I think you just need Gizmos.DrawDirection(<pos>, new Vector3(0,0,1))

46

I need it towards transform.forward not vector3.forward :slightly_smiling_face:

Unlike Vector3.forward, Transform.forward moves the GameObject while also considering its rotation.

new Vector3(0,0,1).applyQuaternion(this.gameObject.worldQuaternion); (just updated with the world data api)

Ah we already also have forward(this.gameObject) that you can import (import { forward } ...). Might also be something useful to add to Object3D

51

I tried this

    update(): void {
        let endpos = forward(this.gameObject).multiplyScalar(100);
        Gizmos.DrawLine(this.gameObject.position, endpos, Color.NAMES.red);
    }
}```
the lines seem very weird and not at all to the forward direction as in the editor

Is this.gameObject parented to something: use this.gameObject.worldPosition
DrawLine draws a line between two points but you do calculate a forward vector here by calling forward. You need to either add the worldPosition to it again if u use DrawLine or you need to call Gizmos.DrawDirection with the forward (endpos) vector

53 
        let direction = forward(this.gameObject)
        Gizmos.DrawDirection(this.gameObject.worldPosition, direction, Color.NAMES.red);
54

your gizmos worked :ok_hand:

55

unfortunately i couldnt get the rotation to work, ill give it up for now :confused:
The method that worked for you failed for me.

56

is there a way to get forward in world space…?

by user 198447544408342528

57

found it, its getWorldDirection with no second argument.

This did not help either, this code

setWorldRotation(this.cam!, getWorldDirection(this.gameObject))

doesnt work either

Can you post your full script again? Im out for today but can try to help again tomorrow or monday :wink:

basically

import { Behaviour, Rigidbody, getWorldPosition, serializable } from "@needle-tools/engine"

export class TeleportPoint extends Behaviour {

    /** The object to move on teleport */
    @serializable(Rigidbody) objectToTeleport?: Rigidbody;

    public teleport(){
        // teleport
        this.objectToTeleport?.teleport(getWorldPosition(this.gameObject));

        // rotate
        // TODO. this not working:
        // let rotation = getWorldRotation(this.gameObject);
        // setWorldRotation(this.objectToTeleport!.gameObject, rotation)
    }

}```

Maybe you can try to update and then use these methods?
