AppleTV support

elvman · December 5, 2015, 7:58pm

I created a new topic for my AppleTV support branch, so that it is clear that you are asking questions about my branch and not others.

URL for the branch: https://github.com/elvman/cocos2d-x/tree/tvos

What is done:

Ported cocos2d-x (including CocosDenshion) to tvOS;
Implemented GCMicroGamepad (also implemented allowsRotation and reportsAbsoluteDpadValues flags);
Compiled all the needed 3rd party libs for tvOS (https://github.com/elvman/cocos2d-x-3rd-party-libs-bin);
Disabled touch events.

What has to be done

Port all samples to tvOS and allow them to be controlled by Apple remote.

To try out the AppleTV port, you can use my sample: https://github.com/elvman/tvos-test

I will post regular updates here. You are welcome post your suggestions, games and experience with Apple AppStore here.

Great work done! Would be interesting to see little FAQ how you got compiled third party libs for Apple TV.

elvman · December 5, 2015, 8:39pm

@energyy You can see the source code here: https://github.com/elvman/cocos2d-x-3rd-party-libs-src

elvman · December 6, 2015, 1:07pm

Removed touch events from tvOS target, because they messed up cocos2d-x GUI. Please use Controllers onKeyDown and onKeyRepeat event listeners instead.

elvman · December 6, 2015, 3:41pm

Added navigation example with menu button in my tvOS sample (https://github.com/elvman/tvos-test). If you are in the game menu, you will get back to main menu with menu button, otherwise the app is closed.

How can I compile sample? There’s tv os library missing…

edit: Found link link, too bad

edit2: brew is working, I’ve installed all depedencies, but still:

error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: no input files specified
fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: Usage: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo [input_file] … [-arch <arch_type> input_file] … [-info] [-detailed_info] [-output output_file] [-create] [-arch_blank <arch_type>] [-thin <arch_type>] [-remove <arch_type>] … [-extract <arch_type>] … [-extract_family <arch_type>] … [-verify_arch <arch_type> …] [-replace <arch_type> <file_name>] …

I’m running following command:

./build.sh -p=tvos --libs=all --arch=all --mode=release

Download the sample from https://github.com/elvman/tvos-test
Download the cocos2d-x tvOS branch: https://github.com/elvman/cocos2d-x/tree/tvos
Download my cocos2d-x build script and put it in the cocos2d-x build directory: https://github.com/elvman/cocos2d-x-build-script
Run “./build.sh -p appletv” to build tvOS libs
Got to tvOS sample xcode settings and change the COCOS2DX_HOME to the location where you have cocos2d-x downloaded:

Anyone has Undefined symbols for architecture x86_64: errors in sample project?

elvman · December 10, 2015, 11:07am

Why are you building for x86_64 architecture? AppleTV has arm64.

piotrros · December 10, 2015, 11:44am

I don’t. I have valid architectures arm64 only. I don’t know why it yells about x86_64.

elvman · December 10, 2015, 11:55am

Are you building for AppleTV simulator?

piotrros · December 10, 2015, 12:13pm

Yeah.

elvman · December 10, 2015, 12:26pm

Of course you are building for simulator. Did you build cocos2d for AppleTV simulator? You should run “./build.sh -h” to see all available platforms.

piotrros · December 10, 2015, 12:55pm

That was it. Thanks again. I forgot simulator has different architecture. Just one more question: now I have 4 directories: Debug-appletvos, Debug-appletvsimulator, Release-appletvos, Release-appletvsimulator. If I want to use simulator I have to add (drag&drop) reference to .a file from Debug-appletvsimulator, so when I want to switch for device (or just release) I have to remove older link and add the new one. Isn’t there easier method? I don’t have to do it while using cocos2d-x for ios or mac. Also why is debug library so huge (over 600mb) while release is small (little over 30mb)?

I don’t have usb-c cable to my apple tv so I have to stick to simulator. In logs I can see:

Controller connected ExtendedGamepad

And when I’m trying some stuff on Apple TV Remove I’m not getting any callbacks…

edit:
Also, did you try using cocos studio scene? I’ve added necessary imports in MainMenu.h:

#include “cocostudio/CocoStudio.h”
#include “ui/CocosGUI.h”

and I’m getting following error:

Undefined symbols for architecture x86_64:

In init I just load scene and add it:

root = CSLoader::createNode("MenuScene.csb");

addChild(root);

elvman · December 10, 2015, 1:17pm

Please, don’t change my sample project. Just set the COCOS2DX_HOME to the location of cocos2d-x and launch it. You don’t have to add anything manually.

piotrros · December 10, 2015, 1:25pm

I tried that, but then I’m getting error that cocos2d.h cannot be found (from Prefix.pch).

edit:
Then I saw red libcocos2d tvOS.a in Frameworks so I’ve added it.

elvman · December 10, 2015, 1:39pm

If cocos2d.h can not be found, then you have a wrong COCOS2DX_HOME path. Please fix it and try again.

piotrros · December 10, 2015, 1:43pm

Ofc I did it first:

iMac-Piotr:cocos2d-x piotr$ pwd
/Users/piotr/Documents/pierdoly/cocos2d-libs/cocos2d-x
iMac-Piotr:cocos2d-x piotr$ ls
AUTHORS cmake plugin
CHANGELOG cocos setup.py
CMakeLists.txt docs templates
CONTRIBUTING.md download-deps.py tests
README.cmake extensions tools
README.md external web
build licenses

edit: Success! I just downloaded your sample and it’s different from older one. Now it builded.

However still no word from apple tv remote as well as linker is throwing the same error about CSLoader, which I described before.

elvman · December 10, 2015, 1:57pm

Apple remote is not working on AppleTV simulator. What linker error did you get?

This remove won’t work? So how I can test it ?
