set animation speed to object's current speed

I am making a boost style 2d sonic game, anyway with the Sprinting animation I have set for sonic the animation speed is a bit scewif. Is there a way I can set the animation speed of his sprinting animation to the current speed that sonic is running at (gradually get faster as sonic moves)?

Sure, but you'll need to figure out the ratio of movement speed to animation speed.

Say, if normal movement speed is 50px/sec and normal animation speed is 10 frames/sec, then you can do this:

Sprite Set Animation Speed to (MovementSpeed/5)

When movement speed increases to 100px/sec, animation speed will also increase to 20 frames/sec.

Or if you want a much bigger increase in animation speed, you can modify the formula to something like this:

Sprite Set Animation Speed to (10+(MovementSpeed-50)/2)
