Disabling multitouch in android?

cocos2d-x C++

Hi!,

Is there anyway to disable multitouch in android? Can’t seem to find a way to do it checking the docs + sources.

Thanks in advance.

If you want disable multi touch on android you can edit Cocos2dxGLSurfaceView.java file
https://github.com/cocos2d/cocos2d-x/blob/master/cocos2dx/platform/android/java/src/org/cocos2dx/lib/Cocos2dxGLSurfaceView.java

and here is the code

        int idTab[] = new int[1];
    float xTab[] = new float[1];
    float yTab[] = new float[1];

    @Override
    public boolean onTouchEvent(final MotionEvent pMotionEvent) {
        // these data are used in ACTION_MOVE and ACTION_CANCEL
        final int id = pMotionEvent.getPointerId(0);
        final float xs = pMotionEvent.getX(0);
        final float ys = pMotionEvent.getY(0);

        final int event = pMotionEvent.getAction() & MotionEvent.ACTION_MASK;

        if (event == MotionEvent.ACTION_DOWN
                || event == MotionEvent.ACTION_POINTER_DOWN) {
            queueEvent(new Runnable() {
                @Override
                public void run() {
                    Cocos2dxRenderer.nativeTouchesBegin(id, xs, ys);
                }
            });
        } else if (event == MotionEvent.ACTION_MOVE) {
            idTab[0] = id;
            xTab[0] = xs;
            yTab[0] = ys;
            queueEvent(new Runnable() {
                @Override
                public void run() {
                    Cocos2dxRenderer.nativeTouchesMove(idTab, xTab, yTab);
                }
            });
        } else if (event == MotionEvent.ACTION_UP
                || event == MotionEvent.ACTION_POINTER_UP) {
            queueEvent(new Runnable() {
                @Override
                public void run() {
                    Cocos2dxRenderer.nativeTouchesEnd(id, xs, ys);
                }
            });
        } else if (event == MotionEvent.ACTION_CANCEL) {
            idTab[0] = id;
            xTab[0] = xs;
            yTab[0] = ys;
            queueEvent(new Runnable() {
                @Override
                public void run() {
                    Cocos2dxRenderer.nativeTouchesCancel(idTab, xTab, yTab);
                }
            });
        }
        return true;
    }

Another way is just go to Cocos2dxGLSurfaceView.java file and go to onTouchEvent
Just comment the switch case case MotionEvent.ACTION_POINTER_DOWN:. No need to modify anything else. It worked for me.

//            case MotionEvent.ACTION_POINTER_DOWN:
//                final int indexPointerDown = pMotionEvent.getAction() >> MotionEvent.ACTION_POINTER_ID_SHIFT;
//                final int idPointerDown = pMotionEvent.getPointerId(indexPointerDown);
//                final float xPointerDown = pMotionEvent.getX(indexPointerDown);
//                final float yPointerDown = pMotionEvent.getY(indexPointerDown);
//
//                this.queueEvent(new Runnable() {
//                    @Override
//                    public void run() {
//                        Cocos2dxGLSurfaceView.this.mCocos2dxRenderer.handleActionDown(idPointerDown, xPointerDown, yPointerDown);
//                    }
//                });
//                break;

```
