Life Skills & Crafting

Overview

UMIPBaseLifeSkillComponent is the shared implementation for life skills (Crafting, Cooking, Alchemy, etc.): per-skill level/EXP (via UMIPBaseLevelComponent), learned recipes, timed crafting with deferred material consumption, and optional bonus yield via UMIPBaseLifeSkillBonusCalculation. Crafting UI widgets live under Widget/Crafting/ and are wired through settings (UMIPSettings life-skill/crafting widget defaults).

UMIPBaseLifeSkillComponent

  • Base: UMIPBaseLevelComponent — save/load, replication, level gates for recipes.
  • Delegates: OnCraftingStartedDelegate, OnCraftingCompletedDelegate, OnRecipeLearnedDelegate, OnCraftingCancelledDelegate.
  • Crafting API: StartCrafting, CancelCrafting, IsCrafting, GetEffectiveCraftDuration, LearnRecipe, HasLearnedRecipe, GetAvailableRecipes, CheckRecipeRequirementByTag.
  • Behavior: Multi-craft runs one cycle at a time; materials consumed when each cycle completes (not at start). Movement can interrupt (movement check timers). Server RPCs: Server_StartCrafting, Server_LearnRecipe, Server_CancelCrafting; clients receive Client_OnCraftingStarted/Completed/Cancelled.
  • Properties: LifeSkillTag (LifeSkill.Type.*), DefaultCraftDuration, CraftDurationReductionTag (ASC tag count / 100 = reduction %), RecipeDataAssets[], BonusYieldCalculationClass, replicated LearnedRecipeTags.

Recipe & output rules

  • Requirements and outcomes are defined in data (FMIPLifeSkillRecipeInfo in MIPLifeSkillTypes.h): inputs, fees, level, output pools (weighted pick vs independent probability per FMIPLifeSkillOutputPool).

Integration

  • Ability System — duration reduction via gameplay tags on the ASC.
  • Inventory — UMIPPlayerServerIMC, slots, and item grants.
  • Currency — fee checks via GetCurrencyComponent().
  • Sound — UMIPClientSoundPlayer binds life-skill crafting delegates for UI audio.
