How to see if mouse is being pressed on an actor?

Maybe you also want to use a MouseInfo method: http://www.greenfoot.org/files/javadoc/greenfoot/MouseInfo.html You can use combinations of some methods. I guess 'mouseDragged' could be the method of your choice.

ah thanks you , it works. but getObjectInRange return object within radius(circle) is there anymethod that get Object and return int withn size(x,y) ?

There is a 'getNeighbours' method that you could use; however, it returns objects within a square or diamond area around the object -- not a rectangular one. I guess you could move the actor left and right and back to original location to encompass a rectangular one (getting neighbors at each place individually).

The difference between the two would be equal to the height of the original image before doubling its height to add the transparent. This is something that you probably would want to avoid. You should probably find a different way to accomplish what you want here. I would suggest that you subclass your actor with my QActor class which is located and d
