Basic Description
- This mod adds a genetics system to the monsters, with every stat being able to mutate in specific ways
- The core stats that are affected are: Health, MoveSpeed, Damage, and AttackSpeed
- The goal of the system detailed below is to allow the game to adapt to the player, and in turn force the player to adapt to it
How it Works
- Every monster has four genes (Health, MoveSpeed, Damage, and AttackSpeed)
- Every minute (or after 40 monster deaths), the algorithm learns from the fallen monsters and adjusts it's "strategy"
- This learning is primarily done through a weighted average system that attempts to judge the "combat effectiveness" of a mutation
Video Explanations
- 1.4.5 - 30-minute overview (outdated, but still semi-accurate)
- 2.4.1 - "Rapid Mutation" overview (outdated, this functionality hasn't been re-added yet)
- 4.1.0 - Challenge Portal Promo
Known Issues/Planned Updates
- A feedback system (visual or other) to let the player know how the mutations are trending
- 4.0.0 hasn't been stress-tested, if you find a breaking bug let me know in the #tech-support channel
- The challenge portal code introduced in 4.1.0 will eventually be changed and hidden, once I decide how to do that
Changelog
4.2.0
- Added a GeneBlocker item for use in GeneticVariantsPatch that prevents stat mutations from effecting the holder
- This item also prevents the holder from scoring points and participating in the fitness evaluation
4.1.0
- Added portal code, compound, and challenge for the artifact (thanks to ArtifactCodeAPI)
- The Genetics challenge will not be required to unlock it for new runs, but...
- The challenge will instead provide a dramatic mutation rate while in the Bulwark (20%-500% instead of base 90%-110%)
- Portal code - in left-right top-bottom order - is TDTCGCTDT
4.0.7
- Fixed the random assignment math that`s been broken since 4.0.0 (oops)
- Monsters now have the chance to get stronger instead of just atrophying away
- Random range is now 90%-110% instead of 90%-90%
4.0.6
- Adjusted/fixed the math in the RecalculateStatsAPI stat hook
- Stat modifications should work like all non-4.0.5 versions now
4.0.5
- Rebuilt the hidden item stats using RecalculateStatsAPI from R2API v3.0.43
- This should help prevent future conflicts with other stat-adjusting mods
4.0.4
- Adjusted TakeDamage hook to avoid certain nullrefs
- This should prevent Glacial Wisps from infinitely exploding when they die
- Adjusted learning algorithm to round to 2 digits before spawning new bodies
- Should prevent fringe cases where items are given when they shouldn`t be
4.0.3
- Algorithm will no longer attempt to give genes to bodies that lack inventories (Barrels, Pots, Vagrant Bombs, Urchins, etc.)
- This would cause nullrefs for these bodies when it tried to allocate their genes
- Mods that give inventories to these special bodies shouldn`t re-break them
4.0.2
- Fixed a potential divide-by-zero error that could happen during the learning cycle
- This would only happen if a given BodyIndex had no scoring children
4.0.1
- Removed caching that was causing some major conflicts with certain lobby mods
- This should fix not being able to start a run in most cases
4.0.0
- Reduced number of genes to 4 (Health, MoveSpeed, AttackSpeed, and AttackDamage)
- Regen and Armor either didn`t apply to most monsters, or were used by the algorithm to "cheat-out" extra points in other stats
- Size never really worked they way I wanted, and balancing it doesn`t make much sense
- The remaining stats should keep the algorithm learning and guessing, instead of just sticking with one stat
- Max and Min gene values have been greatly expanded (0.01 to 10.00, starting at 1.00)
- Max Product has also been adjusted (from 10 down to 1.5)
- This should prevent the algorithm from maxing multiple stats, instead pushing for a more balanced build
- Scoring algorithm has been adjusted to focus on time spent in combat instead of just dps
- Should prevent mega-tanks and glass-cannons, instead pushing for solid combatants
- Learning algorithm has been revamped to use new scores and more data
- Instead of every 10 seconds, the learn only runs every 60 seconds or once enough data (40 monsters) is available
- This may seem significantly slower than before, but the extra data means that it can be "smarter" with it
- Networking is now managed through hidden items
- Host is now the source of truth for the algorithm, no more work for clients
- Rapid Mutation and Infection have been removed
- Infection was unstable at best and buggy more often than it was worth
- Rapid Mutation might come back if demand is high enough, but the new algorithm benefits from having more data
Installation
