Emulate native accelerometer.
Here is my modified version of remote.lua which emulates the native accelerometer.
This means that *any* app which was written for the Corona accelerometer API will work with Corona Remote with the inclusion of just one line in main.lua:
1 | require('nativeremote.lua') |
And here is the code for nativeremote.lua:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 | module( ..., package.seeall ) require( 'socket' ) ------------------------------------------------------------------------------------------------------------------------ -- Initial Values local tcpServer = false local tcpServerStatus = 'asynchronous' local errorCount = 60 local connectionKey = 'CORONAREMOTE1.2' local connectionResponseKey = 'CORONAREMOTE1.2CONNECTED' local port = '8080' local remoteIP = false ------------------------------------------------------------------------------------------------------------------------ -- Async Callback local function asynchronousConnection( event ) if ( event.isError ) then errorCount = 60 else errorCount = 0 tcpClientMessage = {} local function helper( line ) table.insert( tcpClientMessage , line ) return '' end helper( ( event.response:gsub( '(.-)*' , helper ) ) ) Runtime:dispatchEvent( { name = 'accelerometer', xGravity = tonumber( tcpClientMessage[ 1 ] ), yGravity = tonumber( tcpClientMessage[ 2 ] ), zGravity = tonumber( tcpClientMessage[ 3 ] ), xInstant = tonumber( tcpClientMessage[ 4 ] ), yInstant = tonumber( tcpClientMessage[ 5 ] ), zInstant = tonumber( tcpClientMessage[ 6 ] ), isShake = (tcpClientMessage[ 7 ] == '1' and true) or false, } ) Runtime:dispatchEvent( { name = 'heading', magnetic = tonumber( tcpClientMessage[ 8 ] ), geographic = tonumber( tcpClientMessage[ 8 ] ), } ) if remoteIP and tcpServerStatus == "asynchronous" then network.request( "http://"..remoteIP..":8080" , "GET" , asynchronousConnection ) end end end ------------------------------------------------------------------------------------------------------------------------ -- Autostart if system.getInfo( "environment" ) == "simulator" then Runtime:addEventListener( "enterFrame" , function() if tcpServerStatus == "asynchronous" then errorCount = errorCount + 1 if errorCount >= 60 then errorCount = 0 tcpServerStatus = "tcp" remoteIP = false tcpServer = socket.tcp() if tcpServer then tcpServer:setoption( "reuseaddr" , true ) local res = tcpServer:bind( "*" , port ) if not res then tcpServer = nil else local res = tcpServer:listen( 0 ) if not res then tcpServer = nil end end end end elseif tcpServerStatus == "tcp" then tcpServer:settimeout( 0 ) local tcpClient = tcpServer:accept() if tcpClient ~= nil then local tcpClientMessage = tcpClient:receive('*l') if ( tcpClientMessage ~= nil ) then if tcpClientMessage == connectionKey then local communication = connectionResponseKey tcpClient:send( communication .. "\n" ) remoteIP = tcpClient:getpeername() if remoteIP and tcpServerStatus == "tcp" then errorCount = 0 tcpServerStatus = "asynchronous" tcpClient:close(); tcpServer:close() network.request( "http://"..remoteIP..":8080" , "GET" , asynchronousConnection ) end end end tcpClient:close() end end end ) end |

Thanks - very useful

Hi Matt,
Yes, Corona Remote is quite helpful - thanks for putting it together for us!
@ p120ph37
Thanks for making a great tool even better. Now I only have to comment out 1 line when I publish my app.
@zaphod8
You should actually be able to publish the app even without commenting out the one line - the library will automatically detect that it is not running in the simulator and will do nothing.
If you are commenting out the one line because you do not want the additional lua code eating precious space in your .app bundle, keep in mind that even just having the .lua file in the same directory will get it scooped up by the build process and packed into the .app. In other words, if you want to entirely exclude it from the application when doing a build for distribution, you'll need to remove the file itself from the build directory as well.
Hi p120ph37
I will have a look at integrating your additions into the main remote.lua releases.
Thank you for adding something back to the project!
Hope it is helping you in your developments.
Matt
