gesture_rotate_angle

This function is used to set the angle which a pair of touches must exceed in order to trigger a Rotate Start Gesture. The angle is measured in degrees and has a default value of 5°.

Syntax:

gesture_rotate_angle();

Returns:

Real (inches)

Example:

if (gesture_get_rotate_angle() != 5)
{
    gesture_rotate_angle(5);
}

The above code checks to see if rotation angle for gestures is set to 5° and if it is not it sets it to that value.
