Fps Questions and Multiplayer

Ok,

How would you model the player and arms, and set them up so that you have it that other players see your model in multiplayer for example?

How would you go about making sure the gun shoot at center cross hair on screen or in a scope?

How would you make as spread, when you shoot it will shoot slightly off of center at random point?

How should I setup the player? (a capsule for movement? with a player model in it and boxes on the bones as hit boxes, and make the arm bones or shoulders rotate to look up and down ???)

Googled ‘Unity FPS example’ for ya, first result.

For those who have worked with other multiplayer sollutions, Unity’s will seem rather easy. There are good tutorials on this, google it.

Google can be your best friend sometimes, keep that in mind when you have a question.
