I NEED TO HELP ABOUT MY SCRIPT

hello everybody. I edit a game but have a problem. when i touch screen my character jumps two times and plays two times jump sound.

Why is this caused ? I give a command once, but I do it twice

my script;

Code (CSharp):

1. public AudioClip FlyAudioClip, DeathAudioClip, ScoredAudioClip;
2. public Sprite GetReadySprite;
3. public float RotateUpSpeed = 1, RotateDownSpeed = 1;
4. public GameObject IntroGUI, DeathGUI;
5. public Collider2D restartButtonGameCollider;
6. public float VelocityPerJump = 3;
7. public float XSpeed = 1;
8. // Use this for initialization
9. void Start()
10. {
11. }

My best guess is you still have Input.simulateMouseWithTouches set to True (default value). If so I believe in WasTouchedOrClicked() when you begin a touch, Input.GetMouseButtonDown(0) would be True, which causes the first jump. Then when you release your touch you get TouchPhase.Ended which triggers the 2nd jump.

I haven't done much with touch interfaces, so I'm not 100% sure if it works as I described. Try setting Input.simulateMouseWithTouches to False or temporarily remove your check for mouse clicks in WasTouchedOrClicked() to further debug.

Also, your thread title is terrible, being that it doesn't say anything about the kind of issue you're having. I'm actually surprised I even clicked the thread, but I was bored and curious.
