I just need to know how to make a gun shoot and how to apply the controls to make it do that. At the moment i have a simple scene with a gun in view and i’m using the first person controller prefab to move around and look. So how do i make the gun shoot?
You might want to check out this: Its by no means an ideal solution but its one option

The final video in the sequence shows a gun being fired using animation events.
Download the project to see how things are set up.
Not quite what i was looking for, thanks anyways 
First I suggest doing the FPS Tutorial
http://unity3d.com/support/resources/tutorials/fpstutorial
then if you want to get more in depth, try the:
Dastardly Banana -(Free) FPS Weapons Package version 0.9.2:

Great kit.
I’m actually using a gun from that kit but it doesn’t shoot or anything 
On the website, right side, are video tutorials so you can learn to use the kit. =]
Thanks i’ll give it a shot
