Sprite will change whenever it collides with a certain imageObject. HELP!

Hi I'm just new to unity3d. Just want to know how to make this possible with the help from you.

1.) First, the hero_sprite1 remain unchanged when not in collision with the circle_object.
see image below:


2.)When the circle_object collides with the hero_sprite1, it changes to hero_sprite2.
see image below:


3.) Finally, after the collision, the hero_sprite2 will return back to hero_sprite1.

Thanks

 

Something like this should work:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Collision : MonoBehaviour
5. {
6.     public Sprite normalSprite;
7.     public Sprite colliderSprite;
8.  
9.     private SpriteRenderer sr;
10.  
11.     void Start()
12.     {
13.         sr = GetComponent<SpriteRenderer>();
14.     }
15.  
16.     void OnCollisionEnter2D(Collision2D other)
17.     {
18.         // You might want to check that "other" really is the object you want. For example by checking its tag
19.        sr.sprite = colliderSprite;
20.     }
21.  
22.     void OnCollisionExit2D(Collision2D other)
23.     {
24.         sr.sprite = normalSprite;
25.     }
26. }
27.  

 

THank You Very Much sir.. I will start working on it

 

This is my first stepping stone to understand how to create a simple game. Thanks alot

 

Sorry, I've just realised I made an error. It should ofcourse be "Collision2D"! I've edited the example to reflect this.

 

No Probs... the script error said: This message parameter has to be of type: "Collision2D" XD

btw what if... the normalSprite stays as normalSprite whenever it collides only in "BoxCollider2D". Example i made a wall or floor.

 

You could tag all gameobjects that should affect the player and then check if the collision object have the correct tag. Like this:

Code (CSharp):

1. if(other.gameObject.tag == "sometag") {
2. }
3.  

 

Thanks again... i will try this up!
