2D touch input

Hi
I would ccontrol my spaceship in 2d top down space shooter on my adnroid device I would add touch input but when I play the inputs don't exist.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. [System.Serializable]
5. public class Boundary
6. {
7.     public float xMin, xMax, yMin, yMax; //Screen Boundary dimentions

17.     public Transform shotSpawn1;        //Where the Fire Spawn1 extra
18.     public Transform shotSpawn2;        //Where the Fire Spawn2  extra
19.     public float fireRate = 0.5F;    //Fire Rate between Shots
20.     public GameObject Explosion;    //Explosion Prefab

48.             transform.position    = new Vector3(transform.position.x, 0, transform.position.z);
49.         //Excute When the Current Time is bigger than the nextFire time
50.         if (Time.time > nextFire)
51.         {

It looks like you are using pos as several data types here. I'm no expert but you initially state pos as a Vector3 and then declare pos as an int for Input.GetTouch(0).position (returns Vector2 btw) and then calling it back as both a Vector2 and Vector3 when you try to declare pos in world coordinates. I mean if I am wrong by all means, bash me for it. But this just doesn't look right haha.

 

Instead for lines 45 to 47, I'd change to

Code (CSharp):

1. if(Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved)
2. {
3. Vector2 screenPos = Input.GetTouch(0).position;
4. pos = Camera.main.ScreenToWorldPoint(screenPos);
5. //Continue with rest of code

 

Thanks for your reply but it still no get input when I touch the screen

 

I was reading through the forums came across someone having the issue. Is you unity client up to date?

 

yes why?

 

Thought it could've been the cause of a earlier editor. Honestly, i can't give you a good reason to why it's happening cause i am not familiar with touch devices and unity but i thought i would at least try since there were no replies. Try googling the problem and maybe someone has a solution, wish i could've been more of a help.

 

Perhaps try debug.log touchcount to see if it's registering that and move along from there.

Edit: Just saw a forum post where they seemed to have solved it. http://forum.unity3d.com/threads/solved-input-class-no-longer-registers-touches.346663/#post-224509
