Description

This function is used to get the angle within which a touch must be moving towards another touch before a Pinch In Gesture may potentially be started. The angle is measured in degrees and has a default value of 45°.


Syntax:

gesture_get_pinch_angle_towards();

Example:

if gesture_get_pinch_angle_towards() != 45
