Move sprite in Andengine

Question

I want to move sprite on yaxis with some a consistent speed current I am doing just decrement from height of screen to 0 with a constant value. here is the code

this.engine.registerDrawHandler(new IDrawHandler() {
        @Override
        public void onDraw(GLState pGLState, Camera pCamera) {
            ballon.setpostiton(ballon.getX(), ballon.getY() - 1);
        }

    });

But I am not getting consistent when I move my code to different sprite. On small device its ends earlier as compared to large resolution devices and on this more I have passed FillResolutionPolicy in my andengine option.

Please tell me a consistent way to move sprite in Andengine.

Answer 1

MoveXModifier mod1=new MoveXModifier(constanttime,fromX,toX);
sprite.registerEntityModifier(mod1);

Use this modifier for x movement.

MoveYModifier mod1=new MoveYModifier(constanttime,fromY,toY);
sprite.registerEntityModifier(mod1);

Use this modifier for Y movement.

MoveModifier mod1=new MoveModifier(constanttime,fromX,toX,fromY,toY);
sprite.registerEntityModifier(mod1);

Use this modifier for X and Y movement.
