Twas the Night Before

If you celebrate Christmas, a merry Christmas eve to you! If you don’t, happy holidays of whatever form of winter solstice festival you choose to observe! 😉

I’m just about finished testing out spells. I’ve gone through all the different spell schools and cast most of them. In the the process I discovered several bugs and improvements to be made.

For example, I realized it wasn’t clear WHAT monster was taking a turn or at all. If you cast spells that immobilize them or put them to sleep, you had no idea if they were just not moving or what. So I added a “blink” effect on each monster’s action that causes them to flash white, much like the players do. That way you know it’s cycling through monsters and can see if one tried to do something and failed. I considered adding notifications like ‘Bandit is held!” or “Bandit is asleep” as well, but I don’t want to slow down the progression that much. I’d have to wait at least a half-second on each text notification so the player can see them.

So my last couple engine tasks are:

  • Test the last few spells (disarming traps and unlocking doors mainly)
  • Fix regressions in boss combats
  • Reactivate monster special attacks

The numerous fixes I’ve made in other areas may have rectified a lot of the bugs. My next video should be a fight with something big…

After that, I need to start a fresh game from scratch and start playing the game through legitimately, checking that quests, content, and other elements all look good. I only have the first world disk completed, but I want to make sure I personally test all of it before I start involving beta testers.

Also, before I can start getting other people involved in testing, I need to complete the documentation. 🙂 That requires testing and feedback just as much as the game itself!

Phone a Friend

I’ve finally reached my end of year vacation time, hurrah!

Besides holiday stuff going on, I also have a new cat in the house, a beautiful tuxedo long-hair I rescued from Petco. She’s slowly getting used to the house and my other cat, Jack. Currently she isn’t sure about him and hisses if he bounds too close. For his part, he’s ready to worship her!

CRPG work has been ongoing and making steady progress. I’m presently working through every single spell in the game to test code and ensure everything works! I’m a little over halfway through now.

I’ve made several small refinements to the game as I’ve gone along. For example, if you target an enemy one round, on the next round it remembers which one you targeted and defaults to them. I also fixed animation so that all animation occurs when you move. This helps stop the “water doesn’t move when I do” effect which was a little weird. Several spells were tweaked, as was how damage is calculated.

But enough talk, time for another video! In this one, you can see the “Guardian” spell at work, which summons a spiritual ally. Three different random types (bear, wolf, and eagle) are available. There is also another spell which allows you to summon a demon… although their degree of control the summoner has is far less.

Hopefully before the end of the year I will have finished enough to start some closed beta testing with others!

Bug Hunt Blues

Happy upcoming holidays to everyone! Crawling along with the work… Bugs are becoming a major hassle.

I implemented monster and mob movement, which have been disabled for quite some time. This created a perplexing bug where suddenly the game would just screeching crash for no apparent reason… it turned out my NPC mobs were moving onto my player and trying to trigger themselves! This didn’t work because a return stack wasn’t aligned for it.

Another bug happened after I cast a mass heal spell, and the game locked up. It turned out my “generate ally unit” list was including non-existent units, which caused all sorts of unexpected side effects and crashes. I suspect there are further bugs here because I’m still having the odd crash when a monster starts their turn.

And I haven’t even tested all the spell effects yet!

The program is big and complex enough now that small changes can cause regressions in other places I didn’t expect. This is a pain in the neck, to say the least… I want to get the engine to a complete enough state I can start getting some help with play balance testing instead of engine testing.

I was noticing that my party was wiping the floor with most of the monsters, so I increased hit points across the board. I think I may have gone a bit too far that direction, but I think I’ll wait for independent confirmation before any further changes. Rations are super-effective in recovering fatigue, almost TOO much, so they may need to be slowed.

There are plenty of lower-priority bugs as well. I noticed that monsters are spawning in spots they can’t get out of, many NPC’s are missing a “Leave” option so you’re trapped talking to them forever, map exits don’t come out where they are supposed to, and so forth. Content is relatively easy to fix, fortunately.

At some point I’ll also go back through the sound library and rework some of the sounds. I removed the original victory tune because I really wanted something different from Tunnels of Doom.

I also expanded the amount of sound memory available to 8K from 4K, so I actually have more space for complex sounds than I did before. For example, the lightning bolt sound from Tunnels of Doom takes over 360 bytes because it’s an unrolled loop of subtle frequency and volume changes. I don’t think I’ll do anything quite that large, but I definitely want to revise some sounds which I lifted from other TI games and make them my own.

The scariest bug, incidentally, is one on the hardware. I noticed when testing the game engine there that suddenly my party wasn’t able to hit the monsters in melee at all, and the monsters were hitting my characters and critically striking every single time. A very curious behavior… which does not repro in the emulator. I have a suspicion that the timer clock I’m using for the random number generator MAY be skewing things, but I haven’t had time to dig deeply into it yet.

Santa won’t be putting the game in your stockings quite yet, 99’ers… but we’re close!

Trimming the Grimoire

I’ve been hard at work with the game the last few days… There are many bugs to hunt down and features to test!

Part of the fun of playing the game is the refinements you can add to make gameplay better. For example, I realized that swapping between player statistic screens was a bother, having to go back out to travel mode and press a different key. So I changed it so you can go back and forth between characters while on a stat screen by pushing left and right.

Another change was to have it so you can select a player while using services in town; previously the active character was automatically selected. I decided the whole “active character” thing is best kept in travel mode only.

I’m running close to empty in most of my modules for space; several modules I only have around 100 bytes or so of free space left. This means no major new features can be added, and it makes me nervous about any huge changes that may need to happen.

So on the topic of spells…

One thing I’ve noticed after playing the Ultima series is how under-utilized spell systems tend to be. In Ultima III the most used spell in the game was disarm traps, because it was the only way to safely open chests left by monsters. In Ultima IV many spells weren’t used because you had to mix them before you could cast them, which made improvisation in combat difficult. Ultima V had some fun-looking spells like Flame Wind which NOBODY ever used because by the end game your party was strong enough using magic axes to not need spells.

So when I wrote up my spell list a long time ago, I had a goal. I wanted a spell system that was easy and fun to use, and had spells you would WANT to cast because they were cool or useful. In particular, because it was tactical 2D combat, I had a bunch of spells that altered the terrain by creating walls of fire, barriers, and similar things.

But now that I’m actually PLAYING the game, I’m not using those spells at all. In fact, the list of spells is very long with ones I haven’t touched or needed to. So now I’m asking myself “Is this or that spell really needed?”

I originally had 72 spells in the the game. I realized that most of the spells in the first book were getting ignored because they were just pale copies of more powerful spells. I also changed a damage type in the game which meant I had a serious spell gap where the players would have no means to cause that kind of damage. As for the terrain altering ones, they are consuming a lot of memory to support and create, and passive effects like them are just not as fun as I thought.

So now I’m taking a moment to remove the code for these spells and tighten up the spell list. I now have 60 spells instead, which I think is more manageable for both the player and the designer. That also means I can free up a little space in the combat module as well.

Great Balls of Fire

Another video, this time of the fireball spell. I did a video in the older game engine some years back, it was by far the most popular video I did. 🙂 It’s also the one that comes up most frequently in search engines.

One advantage of writing up an FX testing program is I can actually refine the FX a lot easier. I noticed before my fireball’s circle of sprites was moving too slowly and creating a blocky effect. By speeding it up, it actually makes a proper circle.

I’ve also noticed, with the speed of my effects, that four sprites actually looks like a LOT more on the screen, because I’m moving them fast enough to create the optical illusion of more.

And if I change colors at 1/60 of a second rate, it actually creates a pleasing weird hybrid color on the actual TI monitor! (Classic99 doesn’t do this, it in fact occasionally creates a weird optical effect that looks like two sprites of different colors slightly out of sync with each other.)

I’ve still got debugging to do though with the actual effect map of the spells; fireball worked fine but cone attacks didn’t. They are directional so they’re a little more complicated. Onwards…

Anchors Away

Another video, this time of the sailing in action!

The hardest part of it is plotting the ship’s course, which is stored in a transaction. This particular map is slanted which made counting the steps particularly difficult…

Ranged weapons are implemented, as are thrown weapons. The latter are certain melee weapons (like daggers) which you can throw one time per combat. Since this also disarms you and leaves you fighting with bare hands, it’s not always the best option… There are of course some weapons in game that magically return to you each round.

I’ve done a bunch of work with large monsters as well, there was a lot of complications there to sort out. I originally had special attacks enabled and I was surprised and pleased to see my dragon breathe sleep gas at the party! Unfortunately it was also accompanied with a bunch of video buffer overruns and it looks like the sleep state isn’t working quite as intended…

So next is to make sure monster ranged attacks work as intended, and get the special attacks sorted out. I also need to test every single spell in the game to make sure they all work as intended.

Combat 2.0

Combat in action! I still need to re-implement ranged weapons, thrown weapons, and test all spells but looking good…

Many Thanks

A very happy Thanksgiving to everyone! I am always thankful that I have at least a few people paying attention to my project. Despite taking WAY too long on it. 🙂

I’ve been working on an FX tester recently. FX is a huge part of spellcasting in combat, and I need to be able to fine tune that code specifically in isolation so that I can make it perfect without having to hack the game.

There is a lot of aesthetics going into the design, so I need to be able to play with graphics, colors, and other factors quickly. My original “move sprite from A to B” code wasn’t quite perfect either, often over-shooting the mark. I’ve come up with a design that both allows different speeds by only opening interrupts to display sprite position changes at given intervals, and is also completely deterministic so they won’t “shoot past” their mark.

Hopefully I can get most of the engine work done and focus on content… I may have to start beta-testing with only the first 25% of the content complete.

Alpha Ongoing

So I’m definitely in alpha stage with the game engine.

For those of you unfamiliar with software, alpha testing is typically testing of the project with internal testers, and using both white and blackbox testing. At the moment, the sole project employee is me, so I’m doing all of it. 🙂

In the near future, I will have a beta test with a select group of people. I haven’t decided yet on who; feel free to post on this thread if you are interested!

Bear in mind though that being in a beta test means actual testing work, not just playing the game. I would expect bug reports and lots of constant feedback. If you’d rather just wait for the official release to enjoy the game, there’s nothing wrong with that.

Today, I had the unique pleasure of fixing a bug and then seeing several features I hadn’t tested yet work perfectly!

This particular combat, I can see my multiple monster generation system worked like a charm! The rats poisoned occasionally on melee attacks, and the monster AI was fairly good too.

I still have several combat bugs to fix. The fighter, for example, should not be able to cast spells… In fact, the whole spell system has to be fully tested.

I may have to write another side-tool engine to test the FX effects as well. I noticed while debugging the trap ones that there’s a LOT of “artistic adjustment” to make them look just right, and the best place to do that is in a separate tool so I can just cycle through FX and fine-tune them.

Phat Lewt

Despite not having a post for awhile, I’ve been very busy on the game! I’ve been updating the progress page with various bugs and issues. There’s a LOT of code to test and fix; in particular I know the FX code has a lot of issues to deal with.

It’s early to start on it, but I already made some adjustments to game mechanics. I found my first set of encounters the monsters were just a little TOO hard to drop quickly, and they’re supposed to be a nuisance not a full on battle. Hit ratio seems fairly low too; my fighter has swung and missed three times in a row, he should be a bit better than that.

One thing I ended up adding to the game because I had a new module for combat encounter generation and resolution is a complete “you found a chest” system for post-combat. I’m still working through bugs, but you can see it in action here:






I designed it so if a given character is chosen to open the chest, all the others take a step away from it. (Like ANY good adventuring party does.) I need to make sure they don’t move over obstacles like trees though. 🙂

I still need to test the item distribution system as well. The game checks if the player who you try to give the item to has a full backpack or not, offers the option to trade to another player, or discard an item from your backpack to make room. Lots of logic to debug!
