my purpose is to deal w/ 1 button which will appear several times in a game(actually it is the angrybird game) ,then i used the onappear()/observe() but ir can just deal w/ the 1 time the button shows ,following shows can not be deal ,below is my test code ,
what i think is that it can deal each time when button shows until the script end.

below is my test code :
 def myHandler(event):
    click("1373853815762.png")
    wait(5)
Settings.ObserveScanRate=1
onAppear(("1373853815762.png"),myHandler)
observe(FOREVER,background = True)
for i in range(1,5000):
    print "testing....."
    wait(5)
