ImpactMultiTouch

These files provide multitouch functionality to impact. It works in your Desktop Browser, in Mobile Safari and iOS (iOSImpact, ejecta is not tested).

It consists of four parts:

  1. The multitouch plugin multitouch.js
  2. Compatibility files for iOSImpact JS_TouchInput.*
  3. A button class that uses multitouch
  4. Sample code (main.js)

Install

Move the files from this repo over to your impact folder.
If you use iOSImpact check that you don't override the whole Classes Folder, only the needed JS_TouchInput.* files.

Usage

All current touches are saved in ig.input.touches. ig.input.touches is an object, so if you want to iterate over all touches, use:

for ( var t in ig.input.touches ) {
  var touch = ig.input.touches[t]
  // do stuff with touch
}

A single touch looks like this:

{ 
  x:      // The x Position of the Touch
  y:      // The y Position of the Touch
  id:     // The ID of the touch. In Mobile Safari this is what comes out of e.changedTouches[].identifier. 
          // In iOSImpact this is the adress of the Touch Object. 
  state:  // Can be 'down' or 'up'. If the state is 'up' the touch will be removed in the next frame.
}

Important

The multitouch.js plugin overrides the initMouse method of ig.Input. This is required cause the normal ig.Input registers it's own touch handlers which interfere with the ones used here. This could make this plugin incompatible with future versions of impact.

This plugin is tested with impact 1.23
