Touches don't respond correct

Hey Guys,

so I’m trying to work with Unity iPhone, i got Unity-Remote so i could test the gameplay on my device. Here is my Project-Overview:

  • Plattforming/ SideScrolling Game
  • working with ex2D (Spritemanager-PlugIn, works great so far!)
  • I have a character with no scripts attached (okay, that ex2D script…)
  • That character has also one ex2D-Animation (it’s a Move-Animation, Wrapmode is selected as “LOOP”)
  • I made two Buttons (made them in Illustrator, exported them as transparent .png files), and using them as GUITexture-Files on the screen itself

So, the Problem is:

i made two scripts for each button with nearly 1:1 code. The Left-Button should move my Playersprite to the left, the Right-Button should move my Playersprite to the right. This is working. My idea is, AFTER i press one of the buttons, the Character starts to move AND the animation is played. I’m trying to work with the Touch-Phases, but i don’t get a solution i am satisfied with, because sometimes, my device doesn’t recognize a certain phase. When i press the button it’s moving all along, that’s fine (although, the animation is stuck in the first frame and plays the whole animation after releasing my finger from the screen ← how can i solve this “Sideproblem”). When i release my finger, it sometimes doesn’t recognize the Touch-Phase has ended. I made some Debug.Logs to figure out when something happens. I am sitting three days for now in front of this problem, looked up the internet, tried some other “solutions” in order to get nice touch-handling but nothing worked properly, it’s devastating, so i beg you, could someone please help?

Of course here is my code so far:

//public
public float speed = 10.0f;

//private
int touchCount = 0;
    playingAnim = false;

// Objects
GameObject player; 


void Start () {
	player = GameObject.Find("Ritter");

}

// Update is called once per frame
void FixedUpdate () {
	
	moving();		
}
void moving()
{
	
	foreach(Touch touch in Input.touches)
	{
		
		if(guiTexture.HitTest(touch.position))
		{
			Debug.Log("PRESSED");
			
			if(touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Stationary)
			{
				player.transform.Translate(speed*Time.fixedDeltaTime, 0,0);
				player.GetComponent<exSpriteAnimation>().Play("RitterMove", 0);
		
				playingAnim = true;
				
				Debug.Log("PHASE BEGAN - RIGHT");

			}
			else if(touch.phase == TouchPhase.Stationary)
			{
				player.transform.Translate(speed*Time.fixedDeltaTime, 0,0);
            player.GetComponent<exSpriteAnimation>().Play("RitterMove");

				player.transform.Translate(speed*Time.fixedDeltaTime, 0,0);
				
				playingAnim = true;

				
				Debug.Log("PHASE STATIONARY - RIGHT");

			}
			
			else if(touch.phase == TouchPhase.Ended)
			{
				playingAnim = false;
				
				if(playingAnim == false)
				{
					player.GetComponent<exSpriteAnimation>().IsPlaying("RitterMove");
					player.GetComponent<exSpriteAnimation>().Stop();

				}
				
				Debug.Log("ENDE DES BETATSCHENS! - RIGHT");
			}
		}
	}

It looks like
playingAnim = false;
Should be positioned after the condition that checks if it is false.

if(playingAnim == false) {
…
}

playingAnim = false;

That should allow you to stop the animation… the side problem.

For the main issue, could it be that your code is misinterpreting the canceled phase as a begin phase?

http://unity3d.com/support/documentation/ScriptReference/TouchPhase.html

You might be able to confirm if you explicitly handle each touch phase possibility, there are 5, and print a debug log statement for each distinct phase.

This is a late answer I know, but I had same problem as well. I hope this helps someone else.
The solution was to move the code from FixedUpdate() to Update() - that way ended phase was recognized correctly every time.
