Two Way Teleporter using Colliders, a bit of help needed with the secondary platform

Questions & Answers

Hi, I am making a gadget game and could use some help, as many others my coding experience is limited. I have tried finding the answer for this but after seaching for hours i know dare ask this as a question.

I am building a two static teleporter(two telerporter stations that can be used both ways)

buildig a one way teleporter was easy enough(see code below) what i did was create a colider that when anything colides it sends the object to a destination.

public class ColliderTwoWayStaticTP : MonoBehaviour
{
    public Transform destination;
    float lastTP;

    void OnTriggerEnter(Collider other)
    {

        if (Time.time > lastTP + 3)
        {
            //if (other.CompareTag("Player"))
            //{
                other.transform.position = destination.position;
                lastTP = Time.time;
            //}
        }
    }
}

and i attach this to the colider as seen as the top square on the picture PICTURE

this work as expected, the teleporter transports the player, or anything else for that matter to the chosen destination.

now the next step would be to access what happens when another gameObject (in this case the number2 teleporter station) collides with something(anything)

so i would add something like this (**this is not real code**)

public GameObject exit
onCollisionWith(exit,Collider other)
{
if(Time.time > lastTP + 3)
{
teleport other to this.position
}
}

the onCollisionWith is off course not a real function, but this should give the idea of what i am looking for, some way to access the collision happening between a public variable(gameobject or whatever)

I hope this is clear enough

I have a web build of the oneway teleporter, but i can only post one link so PM me if you want it

PS: any help would be appreciated, whether it be in Java or C#

The problem is that the destination teleporter will send you right back. A simple solution would be:

using UnityEngine;
using System.Collections;

public class SimpleTeleporter  : MonoBehaviour {
    public SimpleTeleporter destination;
    private Transform justJumpedSubject;

    void JumpToMe(Transform subject) {
    	// we get the subject to my platform
    	// and prevent it from immediately rejumping
    	subject.transform.position = transform.position;
    	justJumpedSubject = subject;
    }

    void OnTriggerEnter(Collider other) {
    	if (other.transform != justJumpedSubject) {
    		// tell the other side to receive subject
    		destination.JumpToMe(other.transform);
    	}
    }

    void OnTriggerExit(Collider other) {
    	if (other.transform == justJumpedSubject) {
    		// stepped off, don't protect subject anymore against
    		// accidentally teleports
    		justJumpedSubject = null;
    	}
    }
}
