[英]How to animate random objects created on screen in corona sdk
我试图在随机位置在屏幕上单独创建随机对象的动画,对象将在随机位置创建并向右移动,当它们越过屏幕宽度时,它们将从左侧(屏幕外)产生。 我无法理解如何在屏幕上为随机创建的对象设置动画。 以下是我使用的代码。 请帮忙。 谢谢....
--objects that are created randomly
local randoms=math.random
local randomx,randomy
local randomobjname1,randomobjname2
for i=1, 2 do
randomx=randoms(200,400)
randomy=randoms(600,800)
local xlocation=randomx
local ylocation=randomy
local RandomObject[i]=display.newImage("object.png")
RandomObject[i].x=xlocation
RandomObject[i].y=ylocation
if i==1 then
randomobjname1=RandomObject[i]
elseif i==2 then
randomobjname2=RandomObject[i]
end
local function animateobj()
--in this line i have confusion how to pass random x position that i got previously from the above function
randomobjname1.x=randomx
randomobjname2.x=randomx
transition.to(randomobjname1,{time=1500,x=700, onComplete=animateobj})
transition.to(randomobjname2,{time=1500,x=700, onComplete=animateobj})
end
end
你在找这个:
local RandomObject = {}
local xPos = {}
local transitionTime = 1500
local listener2 = function( obj )
transitionTime = 2000 -- U can select as ur need
RandomObject[obj.tag].x = xPos[obj.tag]-400 -- U can even choose a difft. val than '400'
animateobj(obj.tag)
end
function animateobj(i_)
transition.to(RandomObject[i_],{time=transitionTime,x=400+xPos[i_], onComplete=listener2})
end
for i=1, 2 do
RandomObject[i]=display.newImage("object.png")
RandomObject[i].x = math.random(100,300)
RandomObject[i].y = math.random(100,400)
RandomObject[i].tag = i
xPos[i] = RandomObject[i].x
animateobj(i)
end
保持编码............ :)
