How to multiply images[RESOLVED]

[Star]

Okay lets say I want a graphic to appear as a hud. An HP bar so to say. I know how to measure how much HP and MAXHP a character has. But I want more of the graphic to appear depending on how much Max hp I have. Lets say I have 3 hp, I want three hearts instead of one to appear across. How do I multiply method calls depending on max hp and current hp?

def drawmaphp(maxhp, hp, x, y)
back = RPG::Cache.picture("StrawberryEmpty")
cw = back.width
ch = back.height
src_rect = Rect.new(0, 0, cw, ch)
self.contents.blt(x, y, back, src_rect)
meter = RPG::Cache.picture("Strawberry")
cw = meter.width
ch = meter.height
src_rect = Rect.new(0, 0, cw, ch)
self.contents.blt(x, y, meter, src_rect)
end

Then the method call
actor = $game_party.actors[0]
drawmaphp(actor.maxhp, actor.hp, 0, 0)

Use a for loop to repeat the blt times the amount of hp (say, for i in 0...hp), and set the x based on the current loop iteration (i * cw).

I knew that was the answer but I couldn't get it to work, but now I did. Thanks for your help, I finally figured out what the for i in 0 meant. It's so much better than tons of if actor.hp == blah blah blah. :thumb:
