first get to script menu of the things you to be teleported and have there materialName "marble" then go o the script menu of the marbles that teleport the objects and make it's onCollide (e)=>{e.other.materialName == "marble" ? {e.other.pos = scene.my.tpNo0;e.this.timeToLive = 0.001;e.other.vel = [0, 0]} : {} }

is that what you wanted

Let me try

What about the box to the right of the marbles? It should be where the marbles in the course teleport to

just get the red box and type in update (e)=>{scene.mt.tpNo0 = e.this.pos}and where ever they are teleporting to just typ in that update (e)=>{} got it
