Angband Borg

• When using DimDoor to escape, the borg will now choose a spot further away, if the dangers are equal.  This will allow him to get a few more ranged shots in as the monsters approach.
• Radiation mutation was being considered as a ball instead of a dispel effect.
• Certain Dispel effects were passed positive through borg_projectable, but failed in the project_path() from spells1.c  In effect, it was a ‘knight movement’ error.  They show up from time to time.  LOS() is positive going one direction but not the other (monster->player vs player->monster).  I added the reverse LOS check to verify the projection path both ways.
• Before jumping into a pit and casting Mind Wave as a defence, the borg will check to make sure he has sufficient HP.
• Track bad landing zones when trying DimDoor.  There might be an unseen obstacle keeping him from sucessfully jumping.  And he might try to jump onto the same spot repeatedly.  Now he will track bad spots and select a new one.
• Using Mind Wave as a defence had some problems if he was in a room with a few Raals Tomes.  Borg will now keep track of the danger induced from non-effected (empty mind) monsters.  If the danger is too high, he won’t use the Mind Wave defence.
• There was a crash error being caused by a variable being overwritten.  The problem was in the wilderness grids for tracking town location.  That overwrote the array for tracking glyphs.  When a certain glyph was created, it caused a crash.  It was not fun to track down.

I still do not have a version of vanilla angband that will compile in VS2008.  It might take the dev-team a few iterations before they have the dust settled.  I’ll pick up the vborg as soon as they have a version that is compatible with Visual Studio.

I made several changes and updates for the zborg during this past month. Here is a brief run-down.

• MC are allowed to cast spells when blinded
• No AS-corridor digging if a monster is adjacent.
• Borg was getting twitchy after stepping on a special town door. He could not figure out how to flow over the door; he thought it was impassable.
• Borg will keep track of worn items to avoid looping on Best Combo
• Borg was not looking at the minimum fail rate requests for certain mutation activations.
• Borg will consider unknown grids in a region that has been magic mapped at floor grids.
• Borg has a bounce between flowing to a stair in order to leave a level an trying to pick up an item. I told the borg to not pick up items if he was in the process of leaving the level.
• Borg was bouncing between flowing to an asleep town monster (then not attacking it) and flowing to the shops. Once the monster woke up, he attacked it. Borg will be allowed to attack sleeping town monsters.
• Borg with no food will stair scum to get to the surface. In doing so, he will not chase down monsters or items (except food) while in this state.
• Problem with the borg activating the Mutation Mind Blast, thinking it had a radius effect.
• Borg was casting the Mind Wave defence manuever repeatedly, thinking he was blasting some monsters in a darkened room. He will not be required to have seen the monsters more recently.
• Borg might starve to death waiting for summoner monsters to approach him.
• Penalty for dipping into reserve mana when casting Psychic Drain was removed, since that spell returns mana.
• Borg was incorrectly counting certain utility mutations (like WoR) when he ran low on mana.  If the mana ran out, he thought he was out of the utility, when really, he had it, but it was momentarily out of reach due to low mana.
