Questions & Answers
1

I am new in Unity, and i want to add 8 different functions on 8 type of swipe on the screen by finger. I found the code for 4 swipes (left right up and down) but i want to add 8 swipes this shown in image (just for example) .alt text

#pragma strict

private var fp : Vector2;  // first finger position
private var lp : Vector2;  // last finger position

function Update () {
for (var touch : Touch in Input.touches)
{
      if (touch.phase == TouchPhase.Began)
      {
            fp = touch.position;
            lp = touch.position;
      }
      if (touch.phase == TouchPhase.Moved )
      {
            lp = touch.position;
      }
      if(touch.phase == TouchPhase.Ended)
      { 
            if((fp.x - lp.x) > 80) // left swipe
      {
      transform.Rotate(0,180,0);
      } 
      else if((fp.x - lp.x) < -80) // right swipe
      {
            transform.Rotate(0,40,0);
      }
      else if((fp.y - lp.y) < -80 ) // up swipe
      {
             // add your jumping code here
      }
      else if((fp.y - lp.y) < 80 ) // down swipe
      {
             // add your slip code here
      }
  }
 }
}

Here is a bit of untested code. The value of ‘which’ passed to the switch statement start at 0 for directly right and walk around counter clockwise.

#pragma strict

private var fp : Vector2;  // first finger position
 
function Update () {
	for (var touch : Touch in Input.touches) {
		if (touch.phase == TouchPhase.Began) {
		    fp = touch.position;
		}
		if(touch.phase == TouchPhase.Ended) {
            if (fp == Input.mousePosition) return; 
			var dir = Input.mousePosition - fp;
			var angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
			if (angle < 0.0)
				angle = 360.0 + angle;
			var which = Mathf.RoundToInt((angle) / 45.0);
			which = which % 8;	
		    switch(which) {
				case 0: 
				Debug.Log("0");
				break;
				case 1: 
				Debug.Log("1");
				break;
				case 2: 
				Debug.Log("2");
				break;
				case 3: 
				Debug.Log("3");
				break;
				case 4: 
				Debug.Log("4");
				break;
				case 5: 
				Debug.Log("5");
				break;				
				case 6: 
				Debug.Log("6");
				break;
				case 7: 
				Debug.Log("7");
				break;				
				
		   }
		}
	}
}
