Ive been thinking lately about how to implement loops to fly through in the game but I cant figure out how I will do it. If I model a hoop, the middle is empty so how would I check for "collisions" going inside the hoop?

Uhm, a crude method would be to make an invisible object inside the loop, like

if object collision(playerObj, loop)=1 and object collision(playerObj,invObj)=0 then ***colision***

if object collision(playerObj, loop)=1 and object collision(playerObj,invObj)=1 then ***fly on***

Whatever I did I didn't do it!

Yea but you would have to use SIN and stuff to implement the circular effect.

To make it easy for yourself I would use axis aligned hoops, so you don't have to mess about with angles. Then you can do simple box and circle collision. Check whether the player object is or has passed between the front and back of the hoop (a thin space) and then check to see the distance of the player object from the centre of the hoop in 2 dimensions, if the player is within a certain radius then they are in the hoop, and can be marked as having passed through it.
