Script needed

Hi.
I don’t know if I’m posting in the right section, if not, please forgive me.
I’m terrible when it come to scripting, ( i’m an artist.)

Could someone write me a controller that moves on 2 planes, y and x, that goes up down forward backward maybe at 45 Degree too ( pressing up and forward or forward and down, same for backward)?
And is it possible to put a little inertia too it would be to move an object underwater.

If anyone can help that would be great.

Thank you so much for reading.

Did you try the standard assets->prefabs->First Person Controller. There is a ton you can do with it in the inspector without scripting.

thanks DrHotbunz.
I will look at it even through I thing that I may need something more specific.
