I've added an action to my characters that displays a panel when the avatar hits off them. I was just wondering how can I make these characters move as well and then when the avatar hit off them they stop and display the panel!!

is there any tutorial on this or something close to it?

Well I'd suggest you do a basic movement tutorial first.

As a few pointers though your going to end up with two different "states" for your model. A standing state and a walking state.

Read the manual regarding the c_move and related functions and see how you progress.

For the sake of mods, I'd say this was more of a scripting forum question.
