Hybrid Learn by Use (Action Skills)

Increase half of all Perk Damage, Stamina, Harvesting etc. values by using tools and weapons. Upgrade the other half of stat increases using the Perk Tree as normal.

Special thanks to FranticDan and Hells_Janitor for feedback, debugging and suggestions.

Recommend starting a new game.

Currently applies to the tools and weapons for the following Perks:

• Perception: DeadEye, Demolition Expert, SpearMaster, Salvage
• Strength: Boomstick, PummelPete, SkullCrusher, Miner69r/Motherload.
• Fortitude: Brawler, MachineGunner
• Agility: Archery, Gunslinger, DeepCuts, Hidden Strike
• Intellect: Electrocutioner, Robotics

Mod Functionality: (Configurable in buffs.xml)

• Receive a bonus skill point when you max out each Perk Skill (level 50)
• Each Point invested in the game’s Perk Tree gives 20% more Learn-By-Use (lbu) skill progression xp on kills. e.g The default for the lbu_archery skill is each archery kill gives 24 lbu progression xp. With 2 points in the Archery Perk (perkArchery) the lbu_archery skill progression xp is 28.8 (40% increase) per kill.
• The more Experience you have using a tool or weapon, the more you know how to maintain it. Each level of a Learn-By-Use skill decreases associated tool/weapon degradation rate by 1% (total 50%). Doesnt apply to the Hidden Strike or Demolition perks.

WHY ARE THERE ONLY 50 LEVELS?
The mod is using 100 levels, it only calculates and displays every second level to avoid possible rounding errors. So there are only 50 levels displayed in the UI. For a detailed explanation, see the line ” in buffs.xml. (see also: Spinal Tap 1979 – My amp goes to 11. )

Config Options

There are several Global Config Variables used to control the Learn-By-Use functionality and progression curve. See buffs.xml, look for the line: “<!–PLAYER CONFIG VARIABLES…” for the options and further information.

License

The code is free to use license. It is based on the Action Skill levelling algorithm from Khaine in the Darkness Falls mod. Please acknowledge Khaine’s coal-face work if you reuse the code.

This mod comes from the Survival No Trader mod (currently being reworked for 1.0).

Changelog

Version 1.1.1

• Fixed bug that affected Perk Tree bonuses for Harvest/Damage amounts.
• Each level of a LBU perk decreases associated tool/weapon degradation rate by 1% (total 50%). Doesn’t apply to the Hidden Strike or Demolition perks.
• Changed the layout of the Perk List Window. Moved the Search Field above the Perk Tabs. The tabs row now holds up to 6 additional tabs for compatibility with other mods that add tabs.

Version 1.1.0

• Points invested in the default Perk give 20% more lbu_perk progression xp for each point.
  • e.g Default for lbu_archery is each archery kill gives 24 progression xp. With 2 points in the Archery Perk (perkArchery) the progression xp is 28.8 (40% increase).
• Config additions:
  • >lbu_Kill_Bonus: when true, points in a default Perk will give extra progression xp per level.
  • >lbu_Kill_Bonus_Percent: the amount of additional xp given per level invested in the Perk.
  • >lbu_XP_Multiplier: A multiplier for ALL progression xp gained. Increase or decrease if overall progression for Learn By Use skills is too slow/fast

Version 1.0.9

• Full review of DemolitionExpert levelling code. Fixed levelling discrepancies between Molotovs, Grenades, Timed Charges, Explosive Arrows and Bolts.
• Slightly reduced Boomstick levelling progression.

Version 1.0.8

Linux pathing comparability fix

Version 1.0.7 (Bug Fix Update)

Potential fix for Multiplayer code initialisation.

Version 1.0.6 (Balancing update)

• Added config setting to turn off giving a free skill point when each Perk’s Progress is maxed. (On by default)
• Changes to perk level progression speeds:
  • Increased Hidden Strike progression speed.
  • Increased Dead Eye progression speed.
  • Slightly increased Archery progression speed.
  • Slightly decreased Miner69r progression speed.
  • Decreased for Boomstick as each pellet adds experience.

Version 1.0.5

• Optimised the Learn By Use Perks initialisation code. Initialisation now only depends on a single variable rather than the synchronisation of 3 different variables.
• Added Hidden Strike to the Learn By Use Perk Tree.
• Fixed issue where the Miner69r/Motherload Perk allowed the harvesting rate to be applied to plants/farming (e.g. shovels could get extra food when used on farm plot plants)
• Slightly reduced Learn By Use Boomstick xp gain per target hit (shotty can hit multiple targets with a single shell).

Version 1.0.4

• Fixed syntax error in Localisation file.
• Aded Global Config variables so anyone can easily control the Learn-By-Use leveling curve for all Perks.
  • See buffs.xml, look for the line: “<!–change the values below to change the levelling curve….” for information.
• Added Demolitions Expert to the Learn By Use tree. Molotovs & Timed Charges are slow at increasing level.
  • The best way to increase the Demolitions LBU perk is using grenades/rockets on large groups of zombies.
  • Nade should hit a zombie, not land next to it for max level xp.
• Fixed Learn By Use progress error after using Grandpa’s Fergit’n Elixir.
  • After using the Elixir, use any tool or weapon and a buff will restore all Learn By Use Perks’ progress over a short period.
  • Progress Level will also be restored when there are any other Perk Level changes e.g. infection side effects.
  • If you install this version over an existing install/game, you will see a message indicating the progress level is being verified, this is just your local variables being updated to the latest version.
