i like the balistic effect and the ground (if destroyed) hmm, there are game like this, in the BASIC version

Good work. Maybe you could cut a bit of the green off at the bottom so that it is less tall and fits on the screen better. And maybe you could allow 'space' for fire as well.

this is a nice game. I like how it teaches about angles. Is there a way for both players to go at the same time, not take turns? I'm trying to find a simple example of a 2 player game.

There's always a way ;) I'm not sure it'd be best however - though I guess that's mainly down to personal preference. delmar's suggestions would be good - the green at the bottom seems a bit excess at the moment and (seemingly my most common gripe) because of that it doesn't fit on my laptop screen! Also, if I attempt to move whilst the bullet's moving an error arises - might be something you want to look at!

As to computers.fun's question (not sure how to respond to him best) u can simply comment out the cose in the fire button about taking turns and u'll also have to remove the checks inside of Tank and OtherTank with the keypress checks (I call the methods relating to turns in both). For mjrb4: I tried what u said and i didn't get an error on my screen. Yes for the moment I realize there is a bit of excess green but that is a small change i can do if i ever have time to work on it more =/

That's odd, does anyone else get it? The error I get is: java.lang.IndexOutOfBoundsException: X is out of bounds.
