two camera controlled by the mouse

I trying to setting up the a character and I was wondering if someone knew how to control 2 camera without messing up the whole code. I mean I making a 3rd person character and I need to have the 1st view at some time.

if someone could have tsome idea or maybe an example it would be nice

You want to know if you can set up a 3rd person camera that changes to 1st person view?

If so: yes, you can. There is an older demo around somewhere on this forum. Try searching for it. If I happen to run across it, I’ll post the link. Sorry I couldn’t be of more help, but I’ve personally never tried this.
