Teleporting player when key pressed

Questions & Answers

Hello Unity Community,

I made a teleport pad following a tutroial wich is working perfeclty but now I would like it to work only when I press a key. The thing is I’m quite new in scripting and I have no idea how to do this. I tried using Input.GetKeyDown () but it doens’t work or I didn’t do it well.
So if someone has some ideas it would be fantastic :slight_smile:

Here is the script :

using UnityEngine;
using System.Collections;

public class TeleportPad : MonoBehaviour {
public int code;
float disableTimer=0;

void Update(){
	if (disableTimer > 0)
		disableTimer -= Time.deltaTime;

}

void OnTriggerEnter(Collider collider){
	if (collider.gameObject.name == "Player" && disableTimer<=0) {

		foreach(TeleportPad tp in FindObjectsOfType<TeleportPad>()){

			if (tp.code == code && tp != this){
				tp.disableTimer = 2;

				collider.gameObject.transform.position= tp.gameObject.transform.position;
				collider.gameObject.GetComponent<CharacterControl>().rot = 200;
			
			
			}

		}

	}
}

}

Just put

  if (Input.GetKeyDown(KeyCode.Space));

after the void OnTriggerEnter

I had to rework my original logic. See below for an updated version of TeleportPad.cs. I have tested this using 5 teleport pads and it works fine.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class TeleportPad : MonoBehaviour
{
    // the current teleport pad
    public int currentTeleportPad;

    // the teleport pad that we want to go to from the current teleport pad
    public int nextTeleportPad;
    public bool teleportEntered = false;

    float disableTimer=0;
    
    GameObject player = null;
    
    public List<TeleportPad> teleportPads;
    CharacterControl characterControl = null;
    
    void Start()
    {
        if (GameObject.FindGameObjectsWithTag("Player") != null)
        {
            player = GameObject.FindGameObjectsWithTag("Player")[0];
        }
        if (player == null)
        {
            Debug.LogError("Unable to find GameObject with 'Player' tag. Please assign the Player GameObject with the 'Player' tag");
        }

        // make sure that this teleport pad is not equal to the one we want to teleport to
        if (nextTeleportPad == currentTeleportPad)
        {
            Debug.LogError("nextTeleportPad (" + nextTeleportPad + ") and currentTeleportPad (" + currentTeleportPad + ") have the same value. Please Change.");
        }
        
        // make sure that nextTeleportPad and currentTeleportPad is greater than 0
        if ((nextTeleportPad < 1) || (currentTeleportPad < 1))
        {
            Debug.LogError("Either nextTeleportPad (" + nextTeleportPad + ") and/or currentTeleportPad (" + currentTeleportPad + ") has an invalid value. Please Change.");
        }

        // create a list of all the teleport pads
        teleportPads = new List<TeleportPad>(FindObjectsOfType<TeleportPad>());

        // they need to be sorted correctly
        teleportPads.Sort((x, y) => x.currentTeleportPad.CompareTo(y.currentTeleportPad) != 0 ? x.currentTeleportPad.CompareTo(y.currentTeleportPad) : x.currentTeleportPad.CompareTo(y.currentTeleportPad));

        characterControl = player.GetComponent<CharacterControl>();
        if (characterControl == null)
        {
            Debug.LogError("Unable to find component CharacterControl attached to the Player GameObject. Pleas attach one.");
        }
    }

    void Update()
    {
        // change KeyCode to desired KeyCode
        // you may also want to move conditional statement below to FixedUpdate()
        if ((Input.GetKeyUp(KeyCode.Return)) && (teleportEntered))
        {
            teleportEntered = false;
            TeleportPlayer();
        }

        if (disableTimer > 0)
            disableTimer -= Time.deltaTime;
    }

    void OnTriggerEnter(Collider collider)
    {
        if ((!teleportEntered) && (collider.gameObject == player))
        {
            teleportEntered = true;
        }
    }

    void OnTriggerExit(Collider collider)
    {
        // you may need to modify this to meet your logic
        if (collider.gameObject == player)
        {
            disableTimer = 2;
            teleportEntered = false;
        }
    }

    void TeleportPlayer()
    {
        // teleportPads list is 0 based so subtract one from nextTeleportPad
        int nextPadNum = nextTeleportPad - 1;

        // get the next teleport pad to teleport to
        TeleportPad pad = teleportPads[nextPadNum];

        float padYOffset = (player.transform.position.y - gameObject.transform.position.y);
 
        // calculate where to position the player on the next teleport pad
        Vector3 newPlayerPosition = new Vector3(pad.transform.position.x, pad.transform.position.y + padYOffset, pad.transform.position.z);

        player.transform.position = newPlayerPosition;
        teleportEntered = false;
        teleportPads[nextPadNum].teleportEntered = true;
        teleportPads[nextPadNum].disableTimer = 2;

        // clear key buffer so key is not triggered again
        Input.ResetInputAxes();
        
        characterControl.rot = 200;
    }
}

Setup required on each TeleportPad

  1. Add a TeleportPad component to each teleport pad GameObject.
  2. Set currentTeleportPad to the value of the current teleport pad (All unique values).
  3. Set nextTeleportPad to the currentTeleportPad value of where the Player is to be teleported to.
  4. The Player position needs to be relative to the teleport pads.
