I've done it before but can't remember how, I'd like the camera to follow the player but collide and adjust if it hits the terrain etc.

How would I go about this? I've tried placing a "feeler" object to detect the collision and move the camera closer to the player but it's not very nice.

Thanks, Mal.

I would say do a ray cast (or a sphere cast, which adds a "width" to the ray) from the player position to the final camera distance.
Then position the camera at the collision position.

Now the plot thickens, the fps decreases, and the awesomeness goes through the roof.

I put a sphere around the camera with a high radius so it doesn't adjust to small nooks and crannies only large angles. Then I have it ray cast from the character and position it where the collision happened. For buildings to make it a little more smooth, I create a box around the building and use that for collision so that it doesnt collide with detail objects. I just hide the box.

I did something similar, positioned a sphere at the character position and point it at the camera then use this to move it towards the camera:



This works fine! but it seems to cut the fps in half why is it causing so much damage to the fps?

Because

a) you're doing 11 object collision checks per frame with your for loop

b) you're not using Sparky's Collision, which is a lot faster

And if you're doing it like that you could do a sphere cast with Sparky's which will be a lot faster (avoiding the for-loop) and will have the same effect.

Now the plot thickens, the fps decreases, and the awesomeness goes through the roof.

No problem, I'm glad I could help.
The big Thanks has to go to Sparky for making this awesome plugin
