You can use an Actor, a World or null as a parameter for mouseClicked. Not a class.

I don't understand.

You cannot use 'mouseClicked(Actor.class)', 'mouseClicked(World.class)' or 'mouseClicked(<<ANY>>.class)'. The parameter must be some specific visible object that can be clicked on -- a World object (or instance of World) or an Actor object (or instance of Actor). You could use 'null' to see if any click was made; then determine if it was clicked on an Actor object and then determine if that Actor object was of type 't2i1a':

if (Greenfoot.mouseClicked(null))
{
    Actor clicked = Greenfoot.getMouseInfo().getActor();
    if (clicked != null && clicked instanceof t2i1a)
    {
        // etc.
