CoronaSDK Proper Orientation Rotation with Animation
This is a code I came up when learning Lua & CoronaSDK programming. Copy of the original code still available at Ansca code exchange.
It is mostly working as I wanted except a small bug. If you rotate the device while app is loading assets, there might be a small delay. I’m planning to work on an update for that as soon as our game is out…

im also having trouble getting this working with ghost vs monsters demo..
currently in my game i have it set up as
settings =
{
orientation = {
default = “landscapeRight”, },
iphone =
{
plist =
{
CFBundleIconFile = “Icon.png”, CFBundleIconFiles = { “Icon.png”,
“Icon@2x.png”,
“Icon-72.png”,
— “Icon-72@2x.png”, “Icon-Small.png”, “Icon-Small@2x.png”, “Icon-Small-50.png”, “Icon-Small-50@2x.png”,
},
},
},
}
can you send me a sample to try out ??
thanks
I’m afraid I won’t be able to help you with the sample as we are no longer using CoronaSDK. But you should try to add following config directives so orientation section should read:
default = landscapeRight,
content = landscapeRight,
supported =
{
landscapeLeft, landscapeRight
},
I hope this helps…
in landscape mode i have an issue when i rotate the ipad in the right or left direction. each time on the first rotation the content is updsidedown, on the second it looks good & then again on the third upsidesdown…
i have set landscapeRight & left in both files build.settings & rotationfix.lua as described. did i have put something wrong ? thank you.
Hi Ezra,
Have you also put “content” tag in there? That sounds like rotationfix & native rotation working together…
build.settings should look like that ->
orientation =
{
default = landscapeLeft,
content = landscapeLeft,
supported =
{
landscapeLeft, landscapeRight
}
},
I can’t make it work in the Corona simulator in landscape mode in my game.
I tried on Ghosts versus Monsters example and it also does not work.
Does it work for you?
Hi Luciane,
I’ve just replied your ticket and sent u a working Ghost vs Monsters sample project…
Works great on iPad 2. Looks more professional.
Thank you,
Mike
You’re welcome… I’m glad to hear it’s been useful. :)
Hi,
I want to Make the game like some pages are in portrait mode and some are in landscape mode, Using rotation i am not able approach it .
So, please suggest me some tutorials.
Thankyou..
Hi Nirosha, I’m afraid I won’t be able to help you as we’re not using Corona SDK anymore. You should try Coronalabs forum instead…
