I'm having trouble positioning objects according to multiple taps. Whenever two touch are pressed, once one of them has the lowest index and released, the touch count order is modified by affecting the correct positioning of the objects.

I could not use touch.touchid properly, it works in the same way as touch.touchindex

Any hint how to control the x, y coordinates of multiple simultaneous taps without affecting the order of the touches pressed when some other tones are released?

I did something similar for another post:

(open in Chrome as Firefox doesn't like multiple touches)

.

Your events 1-4 are wrong, touch doesn't work like that. You can't "pick touch instance" by comparing its coordinate, as you normally do with sprites etc.

You need to save touchID in a variable in "On any touch start" event. If it's on the left side of the screen, use this TouchID to control the left circle. If it's on the right, control the right circle. On touch end event, clear the variable and return the circle to its original position.
