# Moving while doing loop animation in RPGMaker

I made a custom class to display character portrait in RPGMaker XP Here is the class :

class Poser
attr_accessor :images

def initialize
@images = Sprite.new
@images.bitmap = RPG::Cache.picture('Character.png') #100x300
@images.x = 540 #place it on the bottom right corner of the screen
@images.y = 180
end
end


Create an event on the map to create an instance as global variable, tada! image popped out. Ok nice. But Im not satisfied, Now I want it to have bobbing-head animation-like (just like when we breathe, sometimes bob our head up and down) so I added another method :

  def move(x,y)
@images.x += x
@images.y += y
end

def animate(x,y,step,delay)
forward = true
2.times {
step.times {
wait(delay)
if forward
move(x/step,y/step)
else
move(-x/step,-y/step)
end
}
wait(delay*3)
forward = false
}
end

def wait(time)
while time > 0
time -= 1
Graphics.update
end
end


I called the method to run the animation and it works, so far so good, but the problem is, WHILE the portrait goes up and down, I cannot move my character until the animation is finished.

So that's it, I'm stuck in the loop block, what I want is to watch the portrait moving up and down while I walk around village, talk to npc, etc.

Anyone can solve my problem ? Or better solution ? Thanks in advance
