Rewarding a pet

So, in a map im making you have a lil pet, and i need a cool way to reward of punish them. I was thinking a "black and white" system where you pat the pet, or smash him up. But, unfortunatley, there is no way to get mouse co-ordinates without hacks...

So i need a cheap fix (or otherwise) to make this system. I had an idea to have an un-de-selectable interface unit, and to reward/punish your pet you would click either up and down | or left and right __ respectivley. I could then get the locations of the orders and work out if it was a rough line in either direction.
To do this id just have a look at the angle between points and check it against other stuff, blah. You know what i mean, if the angle is less then 30 degrees then its | if its more then 60 degrees then its __.

Hows this sound, any other ideas, and what do you think woud be the best way to do this system?

All that mouse clicking seems awfully clunky and hard to code.

I would use arrows keys, personally. And maybe 2 ability hotkeys. A for Praise, D for punish.

Press A, then up, and it pets his head. A then left, pets his flank. And so on.

Press D, then right, and it slaps them across the face. And so on again.

That's probably the easiest to code, since A and F are abilities and you can just detect the ability being cast, and then allow for arrow key events.

=(

I want to make it all cool and interactive and dynamic, rather then just hotkeys.
I want to give it a realy nice simple interface, and basicly everything to be mouse controled.

Hmm, ill do sum tests and stuff.

"combos"?
