Angular velocity

Hi,

I need to calculate the angular velocity of an object with sine behavior. I know that:

Angular velovity = delta angle / delta time

but I cannot figure how to calculate the delta angle

Can someone help?

Just keep track of the previous angle in a private variable like 'oldangle'. Then the delta angle would be Sprite.Angle-Sprite('oldangle').

+ System: Always (every tick)
-> Text: Set text to "Angular Velocity: " & (Sprite.Angle-Sprite ('oldangle'))/TimeDelta
-> Sprite: Set 'oldangle' to Sprite.Angle
[/code:1xanolre]

Thanks a lot!
