How to count how many times object passes a certain point?

[Adnihil]

Hey, I'm using the movement extension 'Circular' to have an active object orbit around a point. Now what I'd like to do is count how many times the object has made a complete circle. Is there an easy way to do this?

Maybe use an Active object and a counter. Every time the object collides with the active add 1 to the counter.

You change the center of the Circular Movement dynamically or something?
Otherwise you can simply set the desired X/Y coordinates of the Active object and then use a value/counter.

You can also get the same X/Y coordinates of the object with the center of the circle:
For example you can use an object and the hotspot is the center of the circle.

Int(X( "center" ) + 50 * Cos(Starting Angle)) = 257
Int(Y( "center" ) + 50 * Sin(Starting Angle)) = 235
→ Add 1 to Counter

Oh, of course! That works great, thanks! I had been using custom movements so much that I forgot about collision detection :p

Thanks, but this does not work for higher speeds. For example if you set Spd to 10 and Angular Velocity to -500, the counter will (almost) never go up.
