AnimateType | animate_type | ||
) |
Animates a model from its current position to the given offsets, scale and rotation.
- Parameters
-
x The final x coordinate. y The final y coordinate. scale The final scale. degrees The final rotation. This can be negative to rotate anticlockwise, and can also be greater than 360 to rotate a number of times. absolute If the x, y, scale and degrees values are absolute, or relative to the current transform. Note that absolute animations only work if the model currently has a simple transform. If the model has a shear or some other complicated transform it may result in strange animations. duration The duration of the animation, in milliseconds (1/1000ths of a second). step_time The time between each animation step, in milliseconds. animate_type Specifies what happens when the animation finishes.
