I was thinking of having one graphic of the ammo for each one that the player has.
I want the player to be able to pick up his own shuriken/arrows as well as those that enemies may have thrown; so there would need to be enough room to add ammo beyond the player's default starting amount.
All of the player classes will need a slightly different kind of HUD...
Mage: mana and energy
Rogue: shuriken ammo and caltrop ammo
Fighter: arrow ammo (and an energy bar indicating when they can pull out their shield again?)
I'm not sure how to do this, and I'd like to know how you think it should be done.
Make 3 separate full HUD graphics (mageHUD.png, etc)?
Make the secondary bar (mana, ammo, etc) be it's own graphic, then add it to the stage in the HUD constructor?
