IOS device orientation question: Is this THAT easy?

Hello guys,

Today I started working on screen orientation on my game. The game play’s on landscape mode. I started missing around with orientation runtime listener but get strange results. I then change my builds.settings from (a subset):
[lua]settings = {
orientation =
{
default = “landscapeLeft”,

},
…[/lua]
to:

[lua]settings = {
orientation =
{
default = “landscapeLeft”,

supported =
{
“landscapeRight”,“landscapeLeft”,
},

…[/lua]

And it worked!! All i needed was that the player sees the game upright wether his/her holding the device in landscape mode with the home button left or right. It works great on the device and was wondering if I was doing it the right away? Could it be that simple as adding the supported ={…} line?

Any suggestions will be appreciated it. If that all I needed to do then I can jut move on on my next todo list item!

Thanks guys.

Mo.

ps: when would use the orientation runtime listener then? I can see that there is an shadow rotating around the screen when rotating the device but my game elements just switch without any animation (which I am fine with that) So, if I wanted to use animation on my game elements (buttons, …)when rotating the device, would that be a good use of the orientation listener?

Hi Mo,

Yep, it really IS that easy. :slight_smile:

The difference between this method and using a Runtime orientation listener is basically a matter of personal preference (and how picky you are). As you noticed, this simple method basically just “swaps” the view 180 degrees, while a black shadowbox rotates around.

Using a Runtime listener, you could smoothly rotate the entire screen and every object within it as a whole.

Personally, I use the simple method. It’s easy, virtually automatic, and requires no additional Runtime listener. Listeners take processor power (maybe a small amount, but some). And I never take processor power if the task doesn’t really warrant it. I can’t imagine any end user of my apps caring if the screen rotates smoothly or just swaps 180 degrees.

WOW! Thank you so much Brent for the confirmation. Love it, there is some much to do before releasing an app, this is one more think I do not have to worry:)

THANKS.
