IOS Touch Input Deadzone Workaround

Sep 17, 2020
At the OS-level, iOS handles touch input and enforces a small deadzone. Normally this is fine, but it can prevent very small-change touch inputs.

The fix we found to address this issue is driving most of our input through widgets. To handle our touch input, we just use the touch moved events, which happen after OnTouchFirstMove, so that way the OS shouldn’t be filtering things anymore and should allow for more precise control.
