如题!

给你一段源代码，是我自己做的，控制sprite的，可以参考着来

on mouseDown me
repeat while the mouseDown
if sprite(13).locV <= 501 then
sprite(13).locV=sprite(13).locV
else
sprite(12).locV = sprite(12).locV - 5
sprite(13).locV = sprite(13).locV - 5
updatestage
end if
end repeat
end

on mouseEnter me
if sprite(13).locV > 501 then
set the member of sprite the currentSpriteNum to member "arrowover"
else
set the member of sprite the currentSpriteNum to member "arrow"
end if
end

on mouseLeave me
set the member of sprite the currentSpriteNum to member "arrow"

end

大概的意思就是把角色放在一个通道里，然后判断此物体的坐标值是否大于或小于某一个值，如果条件确定，就使角色每点击一次坐标值就增减

老兄，给做个例子放上来吧！
