I was getting really frustrated with TouchInputPhase not being consistent as well as not being able to check if a touch exists before grabbing it (array exceptions).

Plus your games rock balls.

I have been trying to call my external function through your system and just got it working. Instead of putting my game code inside of the TouchTracker Class I just check and store the fingerId in the external loop like so…

// START NEW TOUCH TRACKING

for (var tracker : TouchTracker in trackers) {
tracker.Clean();
}

for(var touch : iPhoneTouch in iPhoneInput.touches) { // process our touches
var tracker : TouchTracker = trackerLookup[touch.fingerId];

if (tracker) {
tracker.Update(touch);
if (thrust_button_down && thrust_button_touch_ID == tracker.fingerId) {
ThrustDown(touch);
}
if (fire_button_down && fire_button_touch_ID == tracker.fingerId) {
FireButtonDown(touch);
}
// Shield is a toggle
}
else {
tracker = BeginTracking(touch);
if (!thrust_button_down) {
CheckThrust(touch);
}
if (!fire_button_down) {
CheckFireButton(touch);
}
if (!shield_button_down) {
CheckShieldButton(touch);
}
}
}

var ended:ArrayList = new ArrayList();

for (var tracker : TouchTracker in trackers) { if (!tracker.isDirty) { ended.Add(tracker); }}

for (var tracker : TouchTracker in ended) {
EndTracking(tracker);
if (thrust_button_down && thrust_button_touch_ID == tracker.fingerId) {
ThrustUp();
}
if (fire_button_down && fire_button_touch_ID == tracker.fingerId) {
FireButtonUp();
}
if (shield_button_down && shield_button_touch_ID == tracker.fingerId) {
ShieldButtonUp();
}
}

// END NEW TOUCH TRACKING

This way the TouchTracker can stay abstracted and anything new that needs to be added can accessed from outside the Class scope. Believe me I am artist not a programmer so be kind to my code, it may not be very efficient or even a good idea : ) Anyway I had to turn on and off GUITextures and other game code so I could not do it from within the Class. I thought it was going to be a huge boss fight, but its working out really well so far.

You guys rock for sharing everything that you do, so I thought I would add something back to say thanks.
