GLES2.0 2D Render Engine For AndroidSRPGLESEngine is a 2D render engine of opengl ES2.0 for android. It is written in c++ language, and based on common language extension(cle). The advantage is that the engine can be called from c++, java, lua or python language, or make mixed-language games with them. SRPGLESEngine has also win32 version, for developers, they can make and compile games on win32 environment and run on android. Especially for games programmed with c++ language, which is more difficult to debug on android directly than win32. In SRPGLESEngine, many high level classes are defined for developers to construct their games. Such as Frame2DFaceClass, Basic2DObjectClass,GUI classes, and a particle system. These classes has rich attributes and functions to control their appearance to build kinds of games. SRPGLESEngine supports android version android 2.2/3.0/3.2/4.0. SRPGLESEngine using SRPSAGGLibEngine and SRPFSEngine Using GLES : First Methodcopy share libraries of cle into libs/armeabi directory of your project. As follows:
Using template in download page to create your games. Simple_templateActivity public class Simple_templateActivity extends Activity {
private GLSurfaceView mGLView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
StarCoreFactoryPath.InitDefault(Runtime.getRuntime(),"/data/data/com.srpgles.simple_template");
AssetManager assetManager = getAssets();
try{
InputStream dataSource = assetManager.open("SRPFSEngine.zip");
StarCoreFactoryPath.InstallDefault(dataSource, false);
dataSource = assetManager.open("SRPSAGGLibEngine.zip");
StarCoreFactoryPath.InstallDefault(dataSource, false);
dataSource = assetManager.open("SRPGLESEngine_SCP.zip");
StarCoreFactoryPath.InstallDefault(dataSource, false);
}
catch(IOException e ){
}
mGLView = new GLESRenderView(this,getApplication());
setContentView(mGLView);
}
@Override protected void onPause() {
super.onPause();
// The following call pauses the rendering thread.
// If your OpenGL application is memory intensive,
// you should consider de-allocating objects that
// consume significant memory here.
mGLView.onPause();
}
@Override protected void onResume() {
super.onResume();
// The following call resumes a paused rendering thread.
// If you de-allocated graphic objects for onPause()
// this is a good place to re-allocate them.
mGLView.onResume();
}
}GLESRenderView package com.srpgles.simple_template;
...
import com.srplab.www.starcore.*;
class GLESRenderView extends GLSurfaceView {
GLESRender _renderer;
public GLESRenderView(Context context,Application application){
super(context);
// Create an OpenGL ES 2.0 context.
setEGLContextClientVersion(2);
// Set the Renderer for drawing on the GLSurfaceView
_renderer = new GLESRender(this,application);
setRenderer(_renderer);
setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);
this.requestFocus();
this.setFocusableInTouchMode(true);
}

}
Using GLES : Second MethodDownload share libraries of cle from network dynamically. Using this method, install package will be smaller. As follows: import com.srplab.www.starcore.*;
import com.srplab.netinst.*;
public class Simple_templateActivity extends Activity {
private GLSurfaceView mGLView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

StarCoreFactoryPath.StarCoreShareLibraryPath = "/data/data/com.srpgles.simple_template/files";
StarCoreFactoryPath.StarCoreOperationPath = "/data/data/com.srpgles.simple_template/files";
mGLView = new GLESRenderView(this,getApplication());
setContentView(mGLView);
}
@Override protected void onPause() {
super.onPause();
// The following call pauses the rendering thread.
// If your OpenGL application is memory intensive,
// you should consider de-allocating objects that
// consume significant memory here.
mGLView.onPause();
}
@Override protected void onResume() {
super.onResume();
// The following call resumes a paused rendering thread.
// If you de-allocated graphic objects for onPause()
// this is a good place to re-allocate them.
mGLView.onResume();
