我可以让我的对象递增一次,但在第一次按下按钮后它不会继续下降。每次按下按钮,如何使图像对象下降50像素?
local homer = display.newImage ("homer.png", 100, 20)
local button = display.newImage ("button.png",260,460)
local buttonText = display.newText ("Push ME =)", 260, 370, nil, 20)
local spikes = display.newImage ("spikes.png",100 , 500)
function drop ()
homer: removeSelf ()
homer = display.newImage ("homer.png", 100,20)
homer.y = homer.y + 70 -- How to drop homer incrementally continuously
end
button : addEventListener ("tap", drop)
答案 0 :(得分:1)
只需在处理程序中更改对象的y,其他一切都很好:
function drop ()
homer.y = homer.y + 70
end
