If I wanted two objects to switch positions with each other, what kind of code would be needed for that?

Object Switch
You would just need to save the location coordinates of one of them in local variables (declared within the method). Then move it to the location of the other and then move the other to the saved coordinates.
if(Greenfoot.mouseClicked(Jewel.class))
{
int firstX = getX();
int firstY = getY();
if(Greenfoot.mouseClicked(this))
{
setLocation(firstX,firstY);
}
}Of course that will not work. The Jewel object clicked must be this if both 'if' conditions are to be true and therefore you are setting the actor's location to where it already is. You need another object to switch it with -- not the same object. What exactly are you attempting to implement? How are the two objects that are to switch to be identified by the user?
