Oval collision help

-----------------------------------

i want to make a racing game, where you can go anywhere but a circle in the middle, but i cant seem to get the oval collision to work... maybe it doesnt work that way? i want to make it, so the car starts outside the circle in the middle, and cannot go in it? is that possible?

y dont u do the samething as the circle detection, but instead of plugging in the circle therum, u plug in the oval one? x^2+y^2=r1r2

neah, lol.

if its a perfect circle, you just check if the distance between centers of circle and the car and shorter then the radious of the circle or not 8)

x^2+y^2=r1r2

you sure that's the ellipse formula?

isn't it something like this?

(x^2 / a^2) + (y^2 / b^2 )= 1

where a and b are the vertical and horizontal "radius"
