Yes. I'm getting getWindowManager is undefined for wallpaper
and onTouchEvent(MotionEvent) is undefined

do the examples compile for you?

With wallpapers it works a bit different. There's no need to implement "OnTouchListener" etc. Just override the onTouchEvent(event) method in your class that extends RajawaliRenderer:

@Override
public void onTouchEvent(MotionEvent event) {
// ... do what ever you want ...
}

What about getWindowManager being undefined? Is that also used differently
for wallpapers?

http://stackoverflow.com/questions/9052822/where-do-i-use-getwindowmanager-within-live-wallpaper

mContext = getBaseContext();
DisplayMetrics DisplayMetrics = new DisplayMetrics();
DisplayMetrics = mContext.getResources().getDisplayMetrics();
mScreenWidth = DisplayMetrics.widthPixels;
mSreenHeight = DisplayMetrics.heightPixels;


from rajawali.

mSurfaceView.onTouchListener(this); is getting the unreachable code error now. Everything else is fine.

If I use the eclipse recommended fix and remove it, the mContext lines of code get errors.

from rajawali.

Yeah, so in a wallpaper "this" is the Context. So it should be:

DisplayMetrics DisplayMetrics = new DisplayMetrics();
DisplayMetrics = getResources().getDisplayMetrics();
mScreenWidth = DisplayMetrics.widthPixels;
mSreenHeight = DisplayMetrics.heightPixels;


from rajawali.

mScreenWidth and mScreenHeight cannot be resolved to a variable

Would I eliminate

private Point mScreenSize;


What would be used for the screen height and width instead?

Yeah, you don't need all that. Like I said before, you only need this bit of code in your renderer class:

@Override
public void onTouchEvent(MotionEvent event) {
        // ... do what ever you want ...
}

The rest is all taken care of by the Wallpaper class.
So to spell it out literally here's the whole class:

package com.mydomain.wallpapers.mywallpaper;

import javax.microedition.khronos.egl.EGLConfig;
import javax.microedition.khronos.opengles.GL10;

import rajawali.animation.Animation3D;
import rajawali.animation.RotateAnimation3D;
import rajawali.lights.ALight;
import rajawali.lights.DirectionalLight;
import rajawali.materials.DiffuseMaterial;
import rajawali.math.Number3D;
import rajawali.primitives.Cube;
import rajawali.renderer.RajawaliRenderer;
import rajawali.util.RajLog;
import android.content.Context;
import android.view.MotionEvent;
import android.view.animation.AccelerateDecelerateInterpolator;

public class MyWallpaperRenderer extends RajawaliRenderer {
    private Animation3D mAnim;
    
    public MyWallpaperRenderer(Context context) {
        super(context);
        setFrameRate(60);
    }
    
    public void initScene() {
        ALight light = new DirectionalLight();
        light.setPower(1);
        light.setPosition(0, 0, -5);
        mCamera.setPosition(0, 0, -7);

        Cube cube = new Cube(1);
        DiffuseMaterial material = new DiffuseMaterial();
        material.setUseColor(true);
        cube.setMaterial(material);
        cube.addLight(light);
        cube.setColor(0xff00ff00);
        addChild(cube);
        
        Number3D axis = new Number3D(3, 1, 6);
        axis.normalize();
        mAnim = new RotateAnimation3D(axis, 360);
        mAnim.setDuration(8000);
        mAnim.setRepeatCount(Animation3D.INFINITE);
        mAnim.setInterpolator(new AccelerateDecelerateInterpolator());
        mAnim.setTransformable3D(cube);
    }
    
    public void onSurfaceCreated(GL10 gl, EGLConfig config) {
        super.onSurfaceCreated(gl, config);
        mAnim.start();
    }
    
    public void onOffsetsChanged(float xOffset, float yOffset, float xOffsetStep, float yOffsetStep, int xPixelOffset, int yPixelOffset) {
        mCamera.setRotY(xOffset * 10);
    }
    
    // THIS IS WHAT YOU NEED!!!!!!!!!!!!!!!!!!!!!!!!

    public void onTouchEvent(MotionEvent event) {
        RajLog.i("TOUCH!!!!!!!!!");
    }       

    public void onDrawFrame(GL10 glUnused) {
        super.onDrawFrame(glUnused);
    }
}

I appreciate your help as well as others but here is where I am getting
errors. My renderer is fine.

DisplayMetrics DisplayMetrics = new DisplayMetrics();
DisplayMetrics = getResources().getDisplayMetrics();
mScreenWidth = DisplayMetrics.widthPixels;
mSreenHeight = DisplayMetrics.heightPixels;
}
public void onTouchEvent(MotionEvent event) {
//if(event.getAction() == MotionEvent.ACTION_DOWN)
//{
mRenderer.setTouch(event.getX() / mScreenSize.x, 1.0f - (event.getY() /
mScreenSize.y));
//}
//super.onTouchEvent(event);
}
}

Like I said before, remove the "implements OnTouchListener" from the class declaration.
To save me some time, just go over the code I posted carefully and compare it to your own class. It's all in the details ...

Hi,
I have tried your code for wallpaper but it not called ontouchevent from GraffitiLWP . so how can i do it? thanks in advanced.

Thanks,

from rajawali.

I need some help

after writing this code in render class

@OverRide
public void onTouchEvent(MotionEvent event) {
// ... do what ever you want ...
}

where to write this line " mSurfaceView.setOnTouchListener(this); " in which method in render class?

from rajawali.

@flynnfernandes This issue is very old and Im not even certain it applies to your question. Please create a new issue with more context for what you are asking.
