AnimateType  animate_type 
)

Animates a model from its current position to the given offsets, scale and rotation.

Parameters:
xThe final x coordinate.
yThe final y coordinate.
scaleThe final scale.
degreesThe final rotation. This can be negative to rotate anticlockwise, and can also be greater than 360 to rotate a number of times.
