Programming / Re: LambdaHack and new content

« on: May 27, 2015, 04:08:54 AM »

Created some more books that can be used to boost your stats. One such is book of close combat, that gives 3% damage to close combat, but 3% penalty to ranged one.

Fun stuff, as well as the librarian that often carries those. From my experience in my games (but YMMV), 3% bonus to damage dealt is not worth an equipment slot, and if there's a penalty, it's not even worth the turn spent picking it up. OTOH, if you scale up the bonus and the malus, players may be tempted to wear some items for melee combat and take them off for ranged combat. Which may be fun on levels with corridors, where you risk that you start a fight with wrong equipment, but is rather tedius on open levels, where you just need to remember the routine. The joys of endless balancing.

I would like to avoid encouraging micro-management as much as possible. But if 3% is too little for player to consider using the item, I think I'll scale it upwards a bit and maybe introduce some variation to score too.

I also noticed a bug in the engine. If your character has maxed equipment (as many items equipped as possible) and you try to equip one more, the game crashes with error message: execFailure: cannot equip any more items

Thanks a lot. Could you give the the git hash (or commit message) of the commit on the LH master branch that you work with? Also did it happen when the player's leader tried to equip, or another player's actor or the AI faction?

It's commit 06ee15ce77d656b1b23a7ab898150ac41d7eebef (Fix followers that got stuck when leader targeted unwalkable tile). I haven't checked what changes the latest LambdaHack has, I should update sometime soon.

From the error message, it was bname = "Hero 1". It wasn't AI controlled at this time, but by me.

LambdaHack has pretty refreshing take on inventory management and used items. I like that I'm able to equip several weapons that boost my stats and use the strongest one in combat.

I'm glad to hear that. The idea was to make the inventory management as automatic as possible, given that the player controls many actors and also given that newbies should be taken care of until they learn to make their own equipment choices (the 'make your own detailed equipment choices' part is partially WIP, e.g., we still don't have a way to order the actor to attack with a particular weapon).

Great, looking forward to see what kinds other new stuff the future will bring.

I was playing with wands because I thought they could be used to create guns and such. But there's plenty of other things to do, so that can wait. I'm not even completely sure if I want guns in game or not

I was experimenting with creation of wands, but didn't manage to do anything useful (I either burned myself with wand of fire or just threw it away). Looking at https://github.com/LambdaHack/LambdaHack/blob/5476c9352782f6ce688e984673ef06224fef6b04/Game/LambdaHack/Common/Ability.hs I didn't see anything about zapping specifically, so I guess wands aren't currently possible?

Btw, good catch with storm hammer being overpowered. I added a short charging period on it and now it's not as effective at keeping enemies at distance as it was before. I might add some secondary effects on it still, like you have.

Programming / LambdaHack and new content

« on: May 19, 2015, 05:21:19 AM »

I have been poking around with LambdaHack engine again and got couple things I need to understand better. Decided to ask here instead of mailing the author directly so other will benefit from the answers too.

How do items work? Especially are aspects of all items that are being carried active or only those that are currently equipped?

What are EqpSlots used for? For example, ring of Rush has

Code: [Select]

EqpSlot EqpSlotAddSpeed "".

How does rarities work? ItemKind has field rarity that has array of tupples. First value is dungeon level and the second one is rarity. But what does rarity 1 or rarity 10 signify?

Programming / Re: Adding Scripting language to your game(C++)

« on: April 07, 2015, 08:14:08 AM »

There's interesting article at http://carloscarrasco.com/embedding-scheme-for-a-game-mission-scripting-dsl.html that touches the subject briefly. However, it doesn't go that much in detail how to bridge C++ and Scheme are bridged and how to generated foreign function interface easily. CFFI (https://common-lisp.net/project/cffi/) doesn't look too bad, you would need to define each and every C++ function you need to call though. Are there really that many, that it would be too unwieldy?

Yes, lisp is really great language.

Programming / Re: Roguelike with party and mission maps - suggested engine or library?

« on: February 18, 2015, 09:10:45 AM »

I liked writing a game using LambdaHack. It was pretty easy to get things up and running and the developer of the engine even added some neat features I was wondering about. Party based play is neat and you can change tactics of your team on the fly (let them explore the area freely or stick close to you for example). The stumbling block for me was, that I don't know nearly enough of Haskell to actually code anything complicated. I'm planning on getting back to it though, since there are new features being added on the engine that I want to try out.

Thanks, now it works. I played just briefly, so I didn't test everything, but everything so far works. Now I can start tinkering with the new features and see what kinds of things I can do with them. I'm going to add that screen saver mode back in too, should be helpful for testing. And it's fun to watch the game to play itself sometimes

A new version of LambdaHack has been released and I upgraded Space Privateers to use it. Getting the program to type check was pretty fast and straight forward, but I seem to be having a problem in my campaign settings. After starting the game, I get the error:

Internal failure occurred and the following is to blame:

I tried comparing my ModeKind.hs and ModeKindPlayer.hs to those of LambdaHack, but couldn't spot if I have a problem there somewhere.  Now, it would be cool if someone (Mikon for example could give some pointers where to continue solving this problem.

I pretty excited about the possibility to have working storm hammers and privateer grog, so this update is something I want to get working soon.

I'm sure which tools are right depends on the tastes and abilities of the individual programmer. Personally, I've glanced at a few IDEs, and always go "bleh", feeling much more comfortable using a simple text editor (emacs  ) and keeping sources and notes in one big messy directory tree.

I wouldn't call emacs a simple text editor, it's closer to an operating system really. However, I have heard that it has a package (several actually) for editing text (I use emacs a lot and really like how extendable and configurable it is).

Indeed, Calm below 2/3 of max inhibits any item manipulation involving the shared stash.
Also, summoning depends on and uses up Calm. Current Calm also bounds the sight radius.
And a nasty effect: at Calm 0, when an actor is impressed by enemies, he defects.

That last one is quite grave and good motivator keeping ones calm above 0. I wasn't aware of that or the sight radius cap. Thrown potions that lower calm just got really dangerous.

Hey, how did I miss that. Grog has slight boost for calm already, but somewhat more complete model would be neat.

Currently calm affects if character can access to shared cache or use potions. Mikon, was there anything else that it affects?

I think I would wait for timed effects and have a privateers who is somewhat drunk to have advantage in combat. Could even add more alcoholic beverages with slightly varying effects and alcohol content.
