how do you create looping transition in Corona?

[allenjones2003]

Hi,

im new to iphone developing and just starting out using corona, but have come stuck on something and would love someone's help!!

i want to create a looping action where an object of mine stays within the screen boundaries but the x axis constantly moves back and forward so it would basically move from left to right over and over.. any help would be greatly appreciated!!

thanks!

A few weeks ago I put together a video tutorial showing how you can do that in Corona:

Learning Corona w/Ghosts vs Monsters | Game Dev Nation

Okay, technically my example changes the Y coord and something goes up and down, but you could easily modify it to change the X coordinate for side to side movement.

Give it a shot and see if it helps you.

Hi Jay,

just been looking at your tutorial, has been a great help and you described everything great. But once I write the code for my animation the screen goes black so I know something is wrong but i can't find it! can you please help me?
my code so far is:

--> hide the status bar
display.setStatusBar(display.HiddenStatusBar)

--> add wooden block
local woodenblock = display.newImage("wooden_block.png")
woodenblock.x = 240
woodenblock.y = 188

--> block looping

local function woodenblockAnimation()
local animUp = function()
transition.to(wooden_block, { time=400, y=193, onComplete=woodenblockAnimation })
end

transition.to(wooden_block, { time=400, y=183, onComplete=animUp })
end

woodenblockAnimation()


all i want is my image to move from left to right at the top of the screen staying in the screen boundaries and looping constantly.. i know my y axis code is wrong for that but i just used this to get the animation working but i just get a black screen..
any advice would be much appreciated!

thanks

No problem. If I had a nickel for every time I asked for help -- and then found the problem minutes later -- I'd have a LOT of nickels!
