For some reason this code:

2. float[] objPos = obj.sprite.getSceneCenterCoordinates();
3. float dist = (float) Math.hypot(slotPos[0] - objPos[0], slotPos[1] - objPos[1]);
4. Log.d(this.toString(), "Slot Position = "+slotPos[0]+","+slotPos[1]);
5. Log.d(this.toString(), "Object Position = "+objPos[0]+","+objPos[1]);
6. Log.d(this.toString(), "Distance = "+dist);

Is telling me that the two sprites are at the same exact position which isn't true. Is there something goofy about the getSceneCenterCoordinates() method?

EDIT: x + (width*0.5) doesn't work either because it returns the width of the original, unrotated sprite. Anyone who knows for sure what will work?

If something does not work, it usually is a good chance to learn something. You were given two (IMHO perfectly valid) solutions, yet you failed to look at each of them closely enough to make use of them.

AE's source is open. If you are using eclipse, by pressing F3 on a getSceneCenterCoordinates() you can eventually find out, that this method uses returns a static array as a result:

This means, that by calling getSceneCenterCoordinates() method twice, you overwrite the result of the first call.

To make it work, you have two options:
1. Do not call getSceneCenterCoordinates() one-after-another.

2. Provide a local arrays which will be used instead of a static one

I'm not saying your question was bad. I am saying that your attitude was- do not expect everything to be solved for ya.

Okay and what was the other valid solution?

EDIT: Yes it does, thank you.
