Circle to Circle Collisions?

[Amon]

How would I go about making Circle to Circle collisions in CX?

Look into fantomCX, there is a bunch of collision methods in one module. Sorry not at my comp. Let me know if you find it.

Thanks, Mike. I'll have a look now.

Did you found it? Here is one that just relies on the parameters:

'-----------------------------------------------------------------------------
Function Coll_Circle2Circle:Bool(x1:Float, y1:Float, radius1:float, x2:Float, y2:Float, radius2:float)
    Local xf:Float
    Local yf:Float
    Local rf:Float
   
    xf = x1 - x2
    xf *= xf
    yf = y1 - y2
    yf *= yf
    rf = radius1 + radius2
    rf *= rf
    If (xf+yf) < rf Then Return True
    Return False
End

You read my mind, Mike. I was just going to request this but you've don it already. lol

Thanks, Mike.
