*** Sorry, solved this one. A quick game of 'Orcs Must Die' and I realised what it was. It's just an error in the DrawImage command, the rotation wasn't put down correctly ***
Just bought Monkey. I'm still at the stage where every 2nd line of code generates and error and without a debugger I simply can't work out what's causing this one.
I've stripped my code down to the basics and supplied it below. The idea is, when you hit key_left or key_right, the angle of your ship changes, but all I get is 'Array index out of range' and a bunch of errors. The up and down keys work fine, so it doesn't seem to be a syntax error since they're almost identical.
Not sure why it's even mentioning an array since there are none in the program. I tried removing the brackets incase that was confusing it, but it's not that.
