Thanks that was the problem. I have a question about animation, like I hear their is a script that can attach guns to the model is that true? and if so when I animate the model would I just put the guy is apose position like he is carrying a gun and shooting it but in the animation I have no gun in his hands but I could use that attach script to attach the gun to the hands of my model.
Also for that attachment script would I be able to play different animations depending what type of wepon the guy pick up? like lets say the guy picks up a pistal I would want to make a animation for all pistal type weopns use that animation , but if the guy picks up a rocket launcher I would want to play a different animation then to the one with the pistal. I also
need help on how to animate getting in the car's or an airplane ect, would I need to animat the guy opening the door of the car and jumping in? or could I just animate the car with the animation when you press a button that the door opens.

I know that this is alot fo questions and I don't extect people to hand over tip's but this is to let other people that also have these questions to look here for answers.
