The multitouch touch ids appear to be incrrectly set. Unlike the previous incarnation of the multitouch, there is no touch 0, and in the current multitouch, touch #1 is for the left mouse button.
The first touch made is assigned to touch #2, the second to touch #3 and so on.
This script prints out the x co-ordinate of each touch:
and results in these outputs:
1 touch:
5 touches:
10 touches:
I believe that is correct behavior. A repeat is not the way multitouch should be used, when a touch is initiated its ID should be obtained with the StartedTouchOrMouseId expression and stored in some variable for querying further touches (or if you only need to know where a touch started you can just use it directly instead of storing it)
Here is an example where I only needed to process a touch that just started:
Ah, yes. With the new-look condition, I’d forgotten that bit. Thanks for the reminder.
