Lock orientation

Solar2D Daily Builds and Public Releases
#1

Hi,

I really need this function, to lock the device orientation after the main screen?

Can you please put this into a next update?

Thanks! [import]uid: 89239 topic_id: 26951 reply_id: 326951[/import]

You should be able to ‘lock’ the orientation by only listen one supported orientation in the build.settings file. For example, this code should only allow the ‘landscapeRight’ orientation:

settings = {  
 orientation =  
 {  
 default = "landscapeRight",  
 supported = { "landscapeRight" },  
 }  
}

This doesn’t help, I would like to be able to support both orientation in the build file and at some point in the game to lock it on the chosen orientation.

This would be fantastic… [import]uid: 89239 topic_id: 26951 reply_id: 109454[/import]

Using an orientation event listener, you could manually flip your display group when the user turns the device, then, you would just remove the event listener to ‘lock’ the orientation.

Here’s some example code showing how you could rotate the orientation, and then lock it:

display.setStatusBar( display.HiddenStatusBar )   
local button --forward reference so we can change button label  
local currentOrientation = "landscapeRight" --Default in build.settings  
local lock = true  
local group = display.newGroup()  
local widget = require'widget'  
local function lockOrientation(event)  
 if lock then  
 lock = false --turn off the orientation change  
 display.remove(button) -- because of weird bug with button:setLabel  
 button = nil  
 button = widget.newButton{  
 width = 300,  
 height = 90,  
 label = "Unlock Rotation",  
 fontSize = 30,  
 onRelease = lockOrientation,  
 }  
 button.x = 480  
 button.y = 320  
 group:insert(button)  
 else  
 lock = true --turn orientation change back on  
 display.remove(button) -- because of weird bug with button:setLabel  
 button = nil  
 button = widget.newButton{  
 width = 300,  
 height = 90,  
 label = "Lock Rotation",  
 fontSize = 30,  
 onRelease = lockOrientation,  
 }  
 button.x = 480  
 button.y = 320  
 group:insert(button)  
 end  
end  
  
button = widget.newButton{  
 width = 300,  
 height = 90,  
 label = "Lock Rotation",  
 fontSize = 30,  
 onRelease = lockOrientation,  
}  
button.x = display.contentWidth/2  
button.y = display.contentHeight/2  
group:insert(button)  
group:setReferencePoint(display.CenterReferencePoint)  
local function changeOrientation(event)  
 if lock then  
 if event.type == "landscapeLeft" then  
 if currentOrientation == "landscapeRight" then  
 group:rotate(180)  
 elseif currentOrientation == "portrait" then  
 group:rotate(-90)  
 elseif currentOrientation == "portraitUpsideDown" then  
 group:rotate(90)  
 end  
 currentOrientation = "landscapeLeft" -- set orientation to current so that next change we know how much the device was rotated  
 elseif event.type == "landscapeRight" then  
 if currentOrientation == "landscapeRight" then  
 group:rotate(180)  
 elseif currentOrientation == "portrait" then  
 group:rotate(90)  
 elseif currentOrientation == "portraitUpsideDown" then  
 group:rotate(-90)  
 end  
 currentOrientation = "landscapeRight" -- set orientation to current so that next change we know how much the device was rotated  
 elseif event.type == "portrait" then  
 if currentOrientation == "landscapeRight" then  
 group:rotate(-90)  
 elseif currentOrientation == "landscapeLeft" then  
 group:rotate(90)  
 elseif currentOrientation == "portraitUpsideDown" then  
 group:rotate(180)  
 end  
 currentOrientation ="portrait" -- set orientation to current so that next change we know how much the device was rotated  
 elseif event.type == "portraitUpsideDown" then  
 if currentOrientation == "landscapeRight" then  
 group:rotate(90)  
 elseif currentOrientation == "landscapeLeft" then  
 group:rotate(-90)  
 elseif currentOrientation == "portrait" then  
 group:rotate(180)  
 end  
 currentOrientation = "portraitUpsideDown" -- set orientation to current so that next change we know how much the device was rotated  
 end  
 end  
end  
  
Runtime:addEventListener("orientation", changeOrientation)

Hope this helps!

Assuming the above is the main.lua file, here is the build.settings:

settings = { orientation = { default = "landscapeRight", supported = { "landscapeRight" }, } } [import]uid: 38000 topic_id: 26951 reply_id: 109605[/import]

Thanks for your help but using this method I encountered different problems like: the UI Alert messages are upside down and the fonts are acting really strange so this workaround is not helping.

I was hoping for an official function to do this from Ansca…

Thank you! [import]uid: 89239 topic_id: 26951 reply_id: 109852[/import]
