Ineisis on Android - Steps to get working

Ozmodian · 01-19-2013 06:03 AM

Hi There,

So I have been trying to get the Ineisis game working on my Android Tablet (Nexus 7), and have found some steps required I have not seen clearly written anywhere else.

With Esenthel's help, i was able to get the client running on my Tablet and connected to my local server. Here are the steps:

1) Download the Ineisis source code. Follow all steps to get it working along with your Android SDK and NDK (again following the instructions on the website).

2) On the Client Main.es file, make the following changes
a) Change the config to const CONFIG Config=TEST_TO_SERVER;
b) add the following lines to InitPre
Paks.add("engine.pak");
Paks.add("Data.pak");
CurDir(SystemPath(SP_APP_DATA));
c) Remove the data path

// data
//if(Config==FINAL)Paks.add("data.pak", &ClientDataPakSecure);else DataPath("../../../Game/Data");

3) Under Constants.es set the const Str ServerIP= to the server IP
4) Open the Converter Tool and drag and drop the Game\Data folder into the tool.
5) Drag and Drop the resulting .PAK into the Client application in the code editor.
6) Set the Configuration to Android APK
7) Build and Enjoy!

Hi,

Yeah, there are more steps when building for Mobile devices, because originally I was developing the game only for desktops smile

With Esenthel 2.0 I'm heavily improving workflow for game development (thanks to auto publishing and auto packaging most steps won't need to be taken in that version).

Now coming back to your next issue. I think it's because of writing permissions.
Temporary created data (like world, check "Game.es" file, "bool InitGame()", code "Game.World.NewTry") is created relative to current path EE::CurDir, which is by default path of the application, this works on desktop, but on Mobile you can't write to that path, you can only read from it.
On Mobile you can write only to SystemPath(SP_APP_DATA);
Please try doing this:

inside InitPre():

Code:

Str cur_dir=CurDir(); cur_dir.tailSlash(true);

   Paks.add(cur_dir+"engine.pak"); // access resources by full path

   Paks.add(cur_dir+"Data.pak"); // access resources by full path

   CurDir(SystemPath(SP_APP_DATA)); // change path to the place where we can write temporary data

Thanks for the info, that is good to know. I did what you said but now I get an error on start-up again.

Time(16:26:43), App(Esenthel): Can't load pak "/data/app\engine.pak"

I thought it might be the \ so i tried putting tailSlash to false and hardcoding the / but that did not work either.

Time(16:38:01), App(Esenthel): Can't load pak "/data/app/engine.pak"

here is my InitPre(). Thanks as always for your continued help.

Code:

void InitPre()

{

   if(GamePath)CurDir(GamePath);

   App.name("Ineisis Online");

   App.flag=APP_MINIMIZABLE|APP_MAXIMIZABLE|APP_RESIZABLE|APP_FULL_TOGGLE|APP_KB_EX​CLUSIVE|APP_WORK_IN_BACKGROUND|APP_NO_PAUSE_ON_WINDOW_MOVE_SIZE|APP_AUTO_FREE_OP​EN_GL_ES_DATA;

#ifdef DEBUG

   App.flag|=APP_MEM_LEAKS|APP_BREAKPOINT_ON_ERROR;

#endif

   App.x=0;

   App.y=0;

   D.screen_changed=ScreenChanged;

   D.shadow_step=ShadowStep;

   D.reset=Reset;

   // default settings

   D.mode(1024,768).sync(true);

   D.shadowSoft(1).shadowJitter(true);

   D.ambientMode(AMBIENT_LOW);

   D.motionMode(MOTION_HIGH);

   D.edgeSoftenMode(EDGE_SOFTEN_MLAA);

   // load settings

   ConfigLoad();

   D.viewRange(ViewRange);

   Str cur_dir=CurDir(); cur_dir.tailSlash(true);

   Paks.add(cur_dir+"engine.pak"); // access resources by full path

   Paks.add(cur_dir+"Data.pak"); // access resources by full path

   CurDir(SystemPath(SP_APP_DATA)); // change path to the place where we can write temporary data

   // data

   //if(Config==FINAL)Paks.add("data.pak", &ClientDataPakSecure);else DataPath("../../../Game/Data");

    //DataPath("../../../Game/Data");

}

Thanks, I forgot that on android, assets (engine and data paks) are accessed using just their names instead of full paths.

Please try this:
Paks.add("engine.pak");
Paks.add("Data.pak");
CurDir(SystemPath(SP_APP_DATA)); // change path to the place where we can write temporary data
the same thing as before except adding cur_dir to the pak paths

Bravo sir. Mission accomplished! I have updated the description with the necessary steps. Thanks for all your continued work on the engine and on support.
