So im using this code to move around an object, but i dont know how to make it collide with the walls. No matter what I do the gameobject just goes through the walls or if it hits them they bounce. Sorry if its too simple I am new.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class controller : MonoBehaviour {
private float dist;
private bool dragging = false;
private Vector3 offset;
private Transform toDrag;
public Text score;
public int counterofbeers;
public Touch touch;
public bool lampa=false;
void Awake(){
counterofbeers = 0;
}
void Update() {
score.text= counterofbeers.ToString ();
Vector3 v3;
if (Input.touchCount != 1) {
dragging = false;
return;
}
touch = Input.touches[0];
Vector3 pos = touch.position;
if(touch.phase == TouchPhase.Began) {
RaycastHit hit;
Ray ray = Camera.main.ScreenPointToRay(pos);
if(Physics.Raycast(ray, out hit) && (hit.collider.tag == "Draggable"))
{
Debug.Log ("Here");
toDrag = hit.transform;
dist = hit.transform.position.z - Camera.main.transform.position.z;
v3 = new Vector3(pos.x,dist);
v3 = Camera.main.ScreenToWorldPoint(v3);
offset = toDrag.position - v3;
dragging = true;
}
}
if (dragging && touch.phase == TouchPhase.Moved) {
v3 = new Vector3(Input.mousePosition.x,dist);
v3 = Camera.main.ScreenToWorldPoint(v3);
toDrag.position = v3 + offset;
}
if (dragging && (touch.phase == TouchPhase.Ended || touch.phase == TouchPhase.Canceled)) {
dragging = false;
}
}
void OnTriggerEnter(Collider other) {
if (other.gameObject.CompareTag ("pickup")) {
Destroy (other.gameObject); counterofbeers++;
}
if(other.gameObject.CompareTag("wall")){
lampa=true;
}
}
}
