Hello! I'm Tom. I designed a game called Gunpoint, about rewiring things and punching people, and now I'm working on a new one called Heat Signature, about sneaking aboard randomly generated spaceships. Here's some more info on all the games I've worked on, here's the podcast I do, here are the videos I make on YouTube, here are some of the articles I wrote for PC Gamer, and here are two short stories I wrote for the Machine of Death collections.
i love bananas: will i be able to upgrade my ship and buy...
Billy Craig: I just wanted to thank you for this blog post! It...
Ben: Hi Tom, I know this is an old post now, but did you ever...
I got an e-mail today from a developer who’s having trouble making any of their prototypes fun. I’m posting my reply here in case it’s of help to anyone else. This developer was writing because they liked Gunpoint, so that’s why all my examples are from that.
I would suggest three things to bear in mind: Continued
As promised on Twitter, I recently sent everyone on our mailing list instructions on how to get in on a new alpha test of Heat Signature. Keys went out to the first 2,000 people to do so, but I’ll also be keeping the testing list active and inviting people to future alphas from there, so you can still get on it now if you haven’t already. Clarification: this says you can still get on the list, not you can still get in on this alpha test. That test is over and there’s no date for the next one.
If you’re in the alpha: Continued
Hello! I’ll be at Rezzed in London next week, 7-9 April 2016, and you can come and play Heat Signature while I watch, panic, and frantically patch it on a different PC. Saturday’s sold out, but Thurs and Fri tickets are still available. Our artist John Roberts made this fantastic piece for our booth: Continued
Update: Solved! See bottom of post for details.
Hello, more experienced programmers than me! I could use your advice. There’s a code-pattern I’ve been using for a while and I’ve just discovered a problem with it, but I can’t see a great alternative either. I will explain by example: Continued
My summary of where we are after the last ship-generation post would be:
Last time I covered how I taught Heat Signature to build ships out of sectors, join those sectors together, lock some of those doors, then place keycards in the right places to ensure they’re all openable. I’d got the algorithm generating layouts like this, which is great: Continued
I haven’t talked about the way I randomly generate spaceships in Heat Signature since this post – before it even had actual art. That’s partly because I’ve barely touched it since then. I showed the game to developer friends and the press in LA and SF a few weeks ago, and got lots of great input and ideas, but the main thing I came away thinking was: the on-board game needs to be more interesting. And I think better ship interiors are the foundation of that. Continued
Deus Ex’s appeal is often boiled down to ‘lots of options’, but obviously that doesn’t quite cover it. Right now I’m looking to redesign the ‘sneaking inside spaceships’ part of Heat Signature, so I need more than a vague line about what’s cool about Deus Ex – I need a practical understanding of specifically why it works, and why similar games don’t. So I’m replaying Deus Ex 1 and 3, to figure out what it is I want to steal. And I think it is options, but it’s not just number. They have to fill a certain set of requirements, and this is my attempt to nail down what those are.
I’ve been mostly playing Human Revolution so far, but I’ll also use some examples for DX1 since there’s so much overlap. Continued
In maths, ‘natural numbers’ are the ones you might use to count observable, whole things: eg. there are six people here. Anything that doesn’t work in place of ‘six’ there, like 3.4 or -2, is not natural. They’re kind of ‘numbers you can see’.
I’d like to use the term in game design to mean specifically that: numbers you can see. Things that are represented so simply and wholly and countably that you don’t need to display an actual numeric figure to tell the player how much they’re seeing. They can just see. Continued
If you own the Exclusive Edition of Gunpoint on Steam – or the Exclusive Extras as DLC – you now have access to a Windows-only, very rough and time-limited alpha test version of Heat Signature!
If you don’t, though, I don’t recommend buying it just to get in on this! This is very unfinished, very unoptimised, and time-limited: I will close it down in two weeks and then you won’t have it anymore. It exists purely to help me find problems with the game and get people’s thoughts, not necessarily to give them the best experience or one I’d charge for individually. Continued
In general I really like open game development – talking and writing publicly about what I’m working on – but I do have one problem. The time when I want to share what I’ve been making is when, after an exhausting amount of work, I’ve finally created something I’m happy with. But sharing it invites critique: anyone who sees a way it could be better will generally tell you about it. Continued
It’s Sunday, so I’m allowed to work on things that aren’t important. This started as a test for an idea I have of how to create a ‘wake’ that expands behind you, something I ultimately want to use to cut through some layers of cloud as you fly. But I accidentally made a cooler version of the existing contrail, so I tried randomly colouring it, and here we are.
Not sure what to do with it from here. I like everything about it except the end, it has what I call ‘fat tail’ problem: no matter how gently I tell the alpha to fade out, the final, big chunk of vapour always looks like it ends rather suddenly, like your ship just has this big fat tail following it.
I like the idea that breacher ships of different factions would have different contrail colours, though. And I think engine upgrades will probably affect this too.
Here are a million shots: Continued
My current task in Heat Signature is to tweak the airlocks so there’s room to put a closed door between you and the rest of the ship when you board. That way, you have as much time as you like to plan out your attack and wait till the guards are where you want them.
I needed the airlocks to clear 4 squares on the ship’s collision grid, to give you room to stand. But I hit a weird bug: some of them, maybe a third, did not clear. I checked the ‘clear grid’ function was executing on each of them, but still some of them ended up blocked. Continued
I let Eurogamer play Heat Signature and sat in the back seat to passive-aggressively criticise! It went great!
This is both a slightly better looking build than the last trailer, and a longer vid – shows the whole disrupt/isolate/capture cycle.
