MMaps Redux

Patman128 · June 24, 2010

If a creature can't reach a player I think they just switch targets. If they have no other targets, they will get as close as possible and wait in evade mode while still in combat. After a certain amount of time, they will just go back to the spawn location and reset.

kholdfuzion · June 24, 2010

They don't go directly back to spawn, it starts a ~30-45 second timer. If they can't get to a target in that time, they return to home.

Also for random movement they seem to wander in an area ~2x respawn radius if outdoor, indoor is based on size of corridor they are in.

Is there anyway to hack a temporary random movement gen into the next release, I was attempting it, but kept getting an assertion error.

I did the following and it never calls i_path = new PathInfo(&creature, nx, ny, nz); just goes to i_path->Update(nx, ny, nz); and crashes. I will admit I am still learning c++, so I'm a lil stumped as to why its failing.

   if(!i_path)
       i_path = new PathInfo(&creature, nx, ny, nz);
   else
       i_path->Update(nx, ny, nz);

   i_path->getNextPosition(nx, ny, nz);

   Traveller<Creature> traveller(creature);

   creature.SetOrientation(creature.GetAngle(nx, ny));
   i_destinationHolder.SetDestination(traveller, nx, ny, nz);

You probably need to initialize i_path to a null pointer. Look at TargetedMovementGenerator.h, line 43

I think the core implementation is going to get comparatively complicated...

* need to handle the different terrain and movement types
need to check whether or not the creature is swimming/flying (and find the navmesh above/below it), ensure correct behavior if a mob is moved forcefully into terrain it can't move in, etc
* path calculation should be added to the threat/aggro and target selection code
From inside a MovementGenerator, there is no way to produce the correct behavior

* requires PathInfo to be moved to somewhere else, either to the Unit itself or a dedicated PathManager class
* upon initial aggro, a group of mobs should each get their own copy of the first path generated

* need a smarter path following algorithm than current PathInfo::updateNextPosition()

currently, steep slopes cause monsters to walk through the air or ground

* point selection (based on distance and angle to target) should be done after calculating the path

prevent cases where the monsters path takes them through the player

kholdfuzion · June 25, 2010

Thanks, I feel dumb for overlooking it, no more mobs randomly wandering through walls

Well some mobs still do

currently, steep slopes cause monsters to walk through the air or ground

and walls

most visible in Ruins of Silvermoon with max random move set to 2x

Anytime it has to kick back to classic pathfinding mode they still screw up, still this is ALOT better

Thanks for your hard work on mmaps so far.

Unkle Nuke · June 25, 2010

Yeah, I'm afraid mmaps might be turning into a complete rewrite of the entire creature movement system just to make it possible to finish work on mmaps itself!

So much in this game is interrelated and interdependent. I'm amazed half the core devs haven't lost their minds and joined a commune in California, devoted to the worship of plaid religious icons. lol

I guess thats why Linux went modular and so is the real core used by blizzard....hehe...evil Developers and their mad PMS bombs!

faramir118 · June 30, 2010

I pushed the liquid changes.

* Liquid is NOT handled for WMOs, so buildings and most instances haven't changed
* I haven't implemented pathfinding into the aggro/target selection algorithm.
This means that monsters still default to the old way if there is no complete path to the target.
However, monsters will go around lava, deep water, and the like if there is a path.
* There seems to be a memory leak in the generator.
Not a critical problem, but I would like to spend some time fixing it.
* I changed the map extractor again (tiny bug fix), so you need to recompile and rerun

if you have some spare CPU cycles please test the generator with different parameters. I didn't have time recently to do exhaustive testing.

Thanks in advance for any bug reports. Going to be on vacation for a week, but I'll check in.

Unkle Nuke · June 30, 2010

Going to be on vacation for a week, but I'll check in.

Don't you dare! Go have a sunburn and enjoy your time off!

We'll still be here afterward.

faramir118 · June 30, 2010

Hrm, it crashes on Orgrimmar with liquids.

It's the same bug that has happened several times in the past where there is apparently too much mesh data for recast.

I leave in 2 hours, so I suggest you stick with the pre-liquid build. Commit 883c660697483c0edb874cc35382b71eaae78f55 is the last 'safe' one.

I do have ideas on how to go about fixing the problem, but I'm sure not exploring them will be torture for the next week.

Unkle Nuke · July 1, 2010

You've got binary in your veins. Might be a "terminal" condition.

Quickly, nurse! I need 200 CCs of Margarita, 4 oz of Coppertone, and 10 lbs of ice....STAT! Now we must hurry and move him to a beach so we can operate. I think I can save this poor soul.

core or generator?

cyberium · July 10, 2010

I hope Faramir have a good vacation and will be back in great shape to finish his project

faramir118 · July 10, 2010

I've actually been back for a few days now, but I'm still catching up on school/work stuff I missed, and preparing for a final exam. Bleh.

I'll get back into the swing of things soon.

First will be updating to latest mangos rev, then fixing my most recent bungling of the generator.

Unkle Nuke · July 11, 2010

Welcome back, faramir! I trust you had a good time and feel refreshed to face the challenges ahead.

Good luck on your exam!

Afterwards, we're all looking forward to what new developments you have in store for mmaps.

cyberium · July 11, 2010

Good luck Faramir!

DaViper · July 11, 2010

Have fun at your Exams, I already know you'll pass with flying colors....but just in case it gets too stressfull just remeber A+b=D, Blue isn't just a color, and Billy Really does wear Jeans! and Levis, Wranglers, and Bill!...oppps! I wasn't supposed to tell that!...for the world History class, Yes youe instructor is a Caveman, no thier not a Vegitarian and Mac Arther did invade China...by accident so he claims....I guess thats enough of the Cliff Notes to get you thru...and when your done just tell Vladmir we told you the Beer was on Him!

Curious · July 16, 2010

Are you sure it's due to the creature ? It should be the place instead. Have you tried spawn this creature elsewhere en using .debug movemap then ?

p14333 · July 22, 2010

sorry for the newbie question > <'

is there any progress about final release? or there are more things to develope about mmap??

Unkle Nuke · July 22, 2010

Still more development for things like Liquid Types. faramir is currently busy with exams, but he will be back to continue mmaps.

faramir118 · July 23, 2010

I'm still here. Just busy with school:

* writing AI to play Scrabble
* writing MSIL disassembler/decompiler - not an actual assignment, a class I'm taking on viruses spurred my interest
* stupid papers

I promise this project hasn't died!

Good luck on the AI, best if you write it in ProLog though....but don't lack off on the Logic Engine because it could be usefull for other things as well...

The ASM project...thats a great Idea but also look at IDA Pro and they do give it away to students free and it has a lot of compatabilities...I know I use it almost daily for what I do in RL.

and stupid papers are great because in RL if you get into any worthwile job your going to need this skill because there's always a Stupid person who will want to read Stupid Papers....lol

How about a Scrabble addon for WoW, while you at it?

Schmoozerd · July 30, 2010

I would prefer a chess library to be used in kara

Updated to the most recent master revision. Please test the core.

Generator will still crash on Orgrimmar.
