gesture_pinch_angle_towards

This function is used to set 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_pinch_angle_towards();

Returns:

Real (inches)

Example:

if (gesture_get_pinch_angle_towards() != 45)
{
    gesture_pinch_angle_towards(45);
}

The above code checks to see if the pinch in angle for gestures is set to 45° and if it is not it sets it to that value.
