[ASK] Character Customization

[Icecage]

Hi, I want my player to be able to customize his character/avatar and have the character with that same appearance inside the game. If possible different kind of equips can have its own capability (e.g: shotgun spread, machine gun). And each part have their own collision detection, like bigger parts have bigger collision area.

Something like this:

Or maybe like this first for a start:
http://www.kongregate.com/games/Jigg...tform-racing-2
http://www.kongregate.com/games/Berz...plete=commando

It doesn't have to be able to save the avatar for the moment, just create one avatar for each play is nice.

Could someone point me where/how to learn or start?
