Previously, on Bob and Trev: Resurrection...

Game over, man

The competition is nearly at an end, which can only mean one thing - tomorrow's article will be the conclusion, and will (hopefully!) feature a copy of the game to download.

...and here it is.

Does it work?

Um, I think so. After not having quite as much time as I liked to get it finished and balanced today, I then remembered at 11:30 that I hadn't tested the exploding weapons yet. And then spent an age trying to work out why it wasn't working. It turns out I hadn't been very careful with my variable names, and some of the screen output code was overwriting variables which were being used to track what's in range of the explosion. Which made for an interesting round of debugging, where code which used to do something suddenly decided to get stuck in an infinite loop.

As such, I haven't been able to play the game to completion, or do enough playtesting to get the balancing right. And with my current screen telling me I have 498 bytes of RAM spare, I'm not even sure if the game will make it all the way to the end.

Now, please excuse me while I go outside and have a heart attack.

I've never used BeebEM... but at a guess I'd say you forgot to tell it to make the disc writable The 100k image seems to work fine on BeebIt. Providing you remember to flag the disc as writable.

Please don't let them make me be a monkey butler monkeyson.info Posts: 12380	I just had a go with B-Em on the Mac, and it kind of works. Unfortunately I can't turn caps lock off, so when I try to move I get Bad key 'H' messages. You don't validate the filename length when asking the player's name: MONKEYSON is too long and the program crashes waits for BeebEm to download

I guess all it needed was a call to LEFT$() to cut it down to size. attempts to shift the blame to DFS for not providing a nicer error message

There isn't really a limit; it just chooses random locations to place things. But I think there's also a bug that it can place multiple monsters ontop of each other It's quite impressive this. Is the source available in a browser friendly, untokenised format? Not at the moment, but it'll probably be on the webpage, which I guess I'll start work on now-ish. Would be nice if StrongED had an 'export as HTML' option so you could get all the syntax highlighting

I did try making a syntax highlighted one, but the steps were rather convoluted (split program into chunks -> load into BBC BASIC for Windows demo -> print to PDF using CutePDF -> export to HTML using some random tool). The tools I tried for the HTML conversion weren't that great either, and produced over-complicated, messed up formatting. And BBC BASIC for Windows' syntax highlighting is nowhere near as good as StrongED's [Edited by Phlamethrower at 16:46, 17/3/2007]

Getting hit by wielded weapons hurts quite a bit more than I was expecting - enough for some monsters to kill you in one hit on the 2nd level. I'm tempted to tweak the formula a bit, but that would go against the spirit of a 7DRL (i.e., that once the competition is over you're only meant to release bugfixes). I think I'll have to try playing a game where I just run away from any big, scary monsters and see how far I can get
