A significant refactoring of combat code, by Cryp71c, has recently been merged into master. This is a call for testing and bug-hunting, in preparation for .10 release. The changes are live in development builds and on the servers (the testing versions).

List of significant changes for the Unified Combat Control branch:

1. Capitalization of words is performed automatic (done by Kilobyte, altered by SamB)
• Instead of passing an explicit capitalization (NOCAP or CAP) to the mprf system, mprf determines automatically whether capitalization is necessary.
2. Fight rewrite
• Restructuring of combat into phases
• Attempted
• Hit
• Damaged
• Defender Killed
• Dodged
• Blocked
• End
3. Merging of player / monster codepaths
• This comprises the bulk of the rewrite and will be subject for continued (numerous) changes in the future. Some codepaths are not entirely unified because doing so would require symmetry between players and monsters in regards to how a particular effect is handled (weapon brands, spells, etc. etc.)

List of things for players to be aware or mindful of for bug-reporting purposes

1. Out-of-order combat messages (especially as they relate to weapon brands)
2. Combat messages which leak otherwise unknown information
3. Unusual sanctuary behavior
4. Unusual messages or behavior on the last turn of combat (when the monster is killed)
5. Brands, spell effects, or mutations which consistently do not result in a noticeable effect
6. Weapon effects or behavior which do not appropriately result in god-affects
• Examples include using speed weapons with Chei, attacking dishonorably while worshiping TSO
7. Capitalization errors in combat text
8. Missing combat effects (from uniques or from specific player-races)
• Examples include vampire-specific effects for players, or Maurice’s “thieving” attacks

Report bugs here! Thank you in advance!

We had a slight misunderstanding, which unfortunately lead to deletion of many of your online characters from the Trunk/Unstable version on CDO.

We are very sorry and will add a security check to the scripts – promised!

Very recently, something happened in the Crawl world. All the mountain dwarves are gone. Part of the player base revolted, so here are some words to explain the inexplicable.

For quite a while it was realised that MD, HO and Mi are too close to each other than is good for well-differentiated variety. In other words, developers agreed that cutting a species of the three would be an improvement. This was not urgent; that’s why it isn’t announced on the 0.10 development plan or anywhere else. However, it is also not a big change, so when we got the details ready in a session or two, we commenced with the wipeout.

First, theme. Hill Orcs are sacrosanct by Beogh’s protection. Even if you don’t like the orc god, there is no way we would get rid of HO as a player species. Choosing between MD and Mi, the lot hit the former. The reasons are less forcing than with HO, but are reasons nonetheless: Mi has a monster equivalent whereas MD has not (the monster dwarves are deep dwarves, akin to deep elves being the monster elves). Mi has an ancient mythos behind it (Minos, Crete, the labyrinth) as well as a portal vault in the game. MD on the other hand is the archetypical Tolkien-style dwarf, which in my book is a severe demerit.

Second, aptitudes. Removing a species does not happen in empty space. It might have impact on nearby species, and it certainly did so here. A table of the old and new aptitudes for Mi, HO and old MD is at the end of this text. The summary is this: new Minotaurs approached MD in certain areas (e.g. Armour is 2, also Stabbing, Traps & Doors, Evocations). Hill Orcs got additional magical competence.

Third, to dispel a myth. We didn’t use winning rates, or number of games played in order to make a decision.

Fourth, history. Over the course of DCSS, the following species had to resign: HD, GE, El, Gn, OM (Hill Dwarf, Grey Elf, Elf, Gnome, Ogre Mage). Of these, OM merged with Og into a more interesting species; the others left for the same reason MD goes now: lack of differentiation. On the other hand, some species were added over the years: Vp, DD, Fe (Vampire, Deep Dwarf, Felid). 0.10 will probably feature Octopodes. None of these are defined by aptitudes alone (but note that new Ogre is an exception!), which makes for additional complexity but also diversity. Note that species tweaking goes beyond adding and removing: Draconians and Demonspawns were changed (and will probably see further changes), and with some luck and effort, 0.10 will see more interesting Demigods.

An empty entry means no change from the old version of the species.

There is a new change to the skill training in trunk. You don’t have to practise skills to learn them anymore, you can select them starting right at level 0. On the other hand, you need to have some means of training a skill to be able to select it.

To train a weapon skill, you need to carry a weapon of the appropriate type, but you don’t have to wield it. For ranged weapons, carrying a launcher is enough, no need to have missiles.
For armour, you need to wear any armour with an evasion penalty (at least leather). For shields you need to be wearing one. If you can cast condensation shield or have the divine shield ability, that works too.
Spell schools can be trained as soon as you have a spell of the school memorised (whatever the success chance). You can train evocations if you carry any evocable item (no need to wear jewellery or wield rods). For Invocations you can train it if you have a divine ability that uses it.
Fighting, UC, throwing, dodging, stealth, stabbing, T&D and spellcasting can always be trained, there’s no restrictions on them.

Another recent change was made regarding skill levels. You now gain benefit from partial skill levels. This is why it is now displayed with a decimal in the skill screen. For example, casting a dual school spell with both skills at 2.5 is the same as having one skill at 2.0 and the other at 3.0, while it used to be the same as having both at 2.0. You gain a spell slot when spellcasting reaches 2.5, and another when it reaches 3.0.

For those not familiar with the 0.9 skill system, let me recap the changes that were made. XP pool has been removed. When you gain XP, it is immediately spread across the activated skills. The amount of XP attributed to each skill depends on the training percentage. In manual mode, your actions are ignored and XP is spread evenly across all activated skills. In automatic mode, the training percentages depend on which skills you have used recently.
You can also set a skill to focus (marked with *). Doing so will train the skill twice as fast (relative to others of course). In auto mode, if the skill has a very low training percentage, setting it to focus will raise it to around 20% instead of doubling.

Two options have been added:
default_manual_training: if you like to play in manual mode, set this to true and the skill training mode will default to manual instead of auto.
skill_focus: if you don’t want to set skills to focus, set this option to false. This will revert the behaviour to the simple disable/enable toggle, instead of the 3 states disable/enable/focus. If you want to change it in-game, set this option to toggle and you’ll be able to change it from within the skill screen.

As usual, please report any bug you run into on mantis. If you want to comment on the change, there’s a thread at the tavern.
Happy crawling!

There is a new thread in the Tavern, dealing with Implementables. It’s a good place to indicate what features you’d like to see – of the list of current Implementables on Mantis, but you can also lobby for other features beyond that.
