Starcraft: Brood War bot using BWAPI4J

ecgberht's Issues

More defenses at key locations

Right now Ecg only builds one bunker and one turret at the Main Chokepoint that is closest to the Natural Region, some improvements would be:

• Being able to place defenses at other locations like the natural base, this helps FE builds.

• Build more turrets if getting drops or cloaked unit attacks like DTs or Lurkers, helps with #8

• Bunker rush for BBS?

How to use forceStrat key in config.json ?

Hi mate, I'm trying to practice vs various Terran BOs, what values go in this key ?

Improve bunker placement heuristic

Current algorithm sometimes builds the bunker a bit far from the command center.

A nice heuristic could be a mix of key buildings distances and maybe? covered/protected tilepositions by bunker range.

Fix Random opponents learning

Ecgberht learning versus Random opponents is bugged because of BASIL picking a race from the start.
A fix would be generating a learning file for each opponents played race (including proper random)

Use pathfinding to improve proxy build positions

Similar to Proxy Fac logic, calculate best positions near the enemy base that are not near natural paths

BM learning

Add learning to BM Ebay and Proxy Fac

Fix Island Bases mineral recollection

High ground Siege Tanks

Use of JPS to calculate best positions for sieging tanks to protect main path from enemy base

Different strategies per matchup

Right now all of the bot strategies are meant for TvX, so the bot can play worse strategies vs certain matchups (like Bio vs Protoss or Terran).

Current strategies should be reworked/deleted/added so the bot plays using proper metagame and not meme strategies.

One example its the new 2PortWraith build that its good vs Zerg.

Fix Attack

In some test game against the built-in AI Ecgberht stopped attacking after sending the first wave.
Got to 150+ supply but didnt attack when It should have.

Record history of games played per opponent

This history could be used to ponderate the learning, this way the bot will prefer more recently games when deciding what strategy/build to choose.

Improve Kiting method to handle map borders

Full Mech build and behaviour

• ImproveMech Build Order (implemented right now but floats a lot of minerals).

• Add Armory building, upgrades.

• Goliaths.

• Finish #12 .

• Reactive unit composition for mech, add more goliaths if enemy air units spotted, no marines to kill air.

Add Config File and Parsing

Add config file to allow for different config parameters like text debugging, build orders enabled/disabled, tournament mode and debug drawing.

Fix repair

SCVs fail to repair buildings other than bunkers.

Reimplement current Lists as Sets/Maps in GameState class

We are currently using a few Lists that could work better as Sets or Maps because they dont allow duplicates.

/src/ecgberht/GameState.java

Port to BWAPI4J

Port latest version to BWAPI4J
https://github.com/OpenBW/BWAPI4J

Two main benefits from this is:

1. Bot will be faster because of BWAPI4J caching.
2. Being able to use BWEM instead of BWTA.

Taking advantage of this rework also complete #2 at the same time

Fix expansion on some maps with bases blocked by minerals

It was supposed to be fixed with CIG 2018 version but still fails sometimes. Most common map with this problem is Destination.

Firebats against Zerg

The bot should train a few firebats when playing against Zerg, the max amount of firebats should be a fixed value, around 2-3 firebats max, may be increased/decreased depending on the amount of zerglings.

Fix Scouting

Sometimes when destroying enemy main base Ecgberht doesnt send a scouter to check other BaseLocations.
Probably has something to do with the enemyBuildings Set not being empty when It should be.

Improve Agents micro

List of current bugs/improvements to be done:

• Vultures suicide too much, combat sim ignores sunkens?
• Wraiths should be able to target/focus Overlords.
• Wraiths should be able path around the enemy base to target workers/overlords.
• Air agents should run from scourges if they cant kill them before getting hit.
• Vessels dont run away if getting focused
• Vessels irradiate Zerg Eggs ¿?¿? 💩 nvm It was hydralisks morphing into lurkers after getting irradiated.
• Run away from spores.

Change Chokepoint and BaseLocation logic to BWEM

BWTA sometimes gets the wrong chokepoints of some Regions, using BWEM should help with this.
Requires #7 to be done first.

Improve BioMech logic

The marines usually get too far ahead and leave the tanks undefended at the backline, this usually gets the tanks killed and the marines then exposed to the enemy units.

One improvement I have thought is to split the squads by "Bio" and "Mech", setting the "Bio" squads to protect the "Mech" squads and to not get too far from them.

Also tanks wont unsiege when enemies are too close and get killed while sieged.

Add the ability to transition between builds

• Group Behaviour Trees initialization to reset them with an Strategy parameter.

• Some reactive checks to change Strategies on the fly

Improve build location finder algorithm to consider owned areas first

Right now sometimes the bot can build at weird places because of how the location finder algorithm works, It should try to explore first buildable positions belonging to owned Areas/Bases.

Improve worker defense system

Rework it completely as It sucks right now 💩

Add proper drops

Dropships are already implemented but only for island expansions (not used right now because of BWAPI bug).

Should be just adding new logic to DropShipAgent to pick units, follow a proper path to the enemy base and to drop them to cause the max amount of damage to the economy (killing workers, etc.).

Test AIST S2 Map pool

Test if choke/base detection logic works fine and army doesnt derp anywhere with AIST S2 map pool:

• (2) Benzene

• (2) New Heartbreak Ridge

• (3) Aztec

• (4) Circuit Breaker

• (4) Eddy

• (4) Fighting Spirit

• (4) Roadkill 1.08

AIST S2 planned improvements and fixes

Fix these current opened issues:

• #42

• #40

• #35

• #34

• #16

• #23 ?

Other improvements/fixes:

• Fix tanks looping (siege -> unsiege, repeat) when enemy targets are in range but not visible 🤔

• Vessels still run fly float into scourges 😞

• Vultures suicide when retreating 😥

• Implement high ground siege tanks (insert star wars prequels meme)

• Ebay bm and proxy fac learning?? (kinda similar to SH gas steal or locutus pylon bm)

• Medic only squads should move to closer non-medic squad instead of chilling around the nearest Command Center 🍹

• Implement own fixed getDistance method

• Add new memes 👍

Fix InfluenceMap

Something its wrong with it, Squads dont try to attack enemy buildings in sight and only move to the center of the enemy base.

Add EMP vs Protoss

Not sure if worth it but It would be really easy to implement because Its similarity with the Irradiate implementation.

Dynamic Gas workers allocation system

This will cause less floating gas and more minerals income, will improve overall strength of Bio strategies.

Check availability of scans

The bot should check whether comsats have enough energy to cast scans before sending units into lurkers.

See replay for 2018-04-13 17:09:57.

Change Build movement to center Position of building instead top left TilePosition

SCVs start building from the center position so It should be better to move them to that center position instead the topLeft Position when moving to the build location.
This change also needs mineral prediction changes.

Refactor almost everything

Right now GameState its too big and does too many things, It should contain objects relegated to general tasks and manage them.

Fix Squad movements

Sometimes the marines get stuck at ramps/chokepoints when changing the "objective" to attack.
Orders should be issued instantly instead of waiting for the squad to get close to the previous objective.

Improve scans and detection of cloaked units

Issue related to #6

• Use scans only when being able to kill invisible units.

• Squad retreating if no detection available against cloaked units.

• Training of Science Vessels and implementing an agent for them.

Add mineral walking and scouting to improve play on "Fortress" AIIDE map

This map has some semi islands expansions that can be reached using mineral walking, the bot should be able to expand to this bases(floating CCs or using mineral walk) and to explore, scout and attack them in case the enemy decided to expand to one of this bases.

Give and check buffer when building Factory

Factory needs some space to build the addon, currently not implemented in our BuildingMap class.
It should check the extra size required for the addon when choosing the position where to build the new Factory and also update the map with the extra addon size.

The bot currently gets bugged when the factory has no space for constructing the addon.

Rework Army management and micro

Current Army management and micro its a bit underwhelming, needs a rework to be improved.

Fix Wraiths

Related with #22, wraith logic was is borked.
Atm the wraiths just flee when there are enemies close enough to the cluster which the wraith belongs, It should consider wraith's distance to enemy units to see It if can kite any of them or one of the units are close enough to be a danger. Logic before used tried to do that but It was awful and didnt work.

Improve detection of Cannon Rushes and add proper countermeasures

Also dont expand if cannons are close 😉

Track supply

Because of latency supply is not tracked correctly when not playing singleplayer, this messes up some timings that check supply numbers like scouting.
