Relationship System for Game Creator 2

Relationship System transforms how characters interact in your Game Creator 2 projects. Build dynamic reputation systems, complex faction hierarchies, and diplomatic relationships—all without writing code.

Imagine a guard who trusts you enough to look the other way, a guild that shuts its doors because you sided with their enemies, or a companion whose loyalty shifts after one too many questionable decisions. These aren't scripted moments — they emerge naturally from a living system of values, levels, and factions that react to everything the player does.

Setting it up takes minutes, not hours. Drop a component on your characters, define what "Friendly" or "Hostile" means to you, and wire it up through Game Creator 2's visual scripting. No code required. When the player completes a quest, a single instruction adjusts the relationship. When that value crosses a threshold, your UI updates, your NPCs react, and your world feels alive.

Relationship System tracks relationships as data:

• symmetric or directional levels with linear, curve or asymmetric decay
• stackable Caps (min/max clamps per source)
• Temporary Modifiers (flat or percentage, stacking, duration, Gain-Only/Loss-Only/Both)
• a Diplomacy state machine (War/Neutral/ Friends) with validated, auto-triggering transitions, a trade modifier and travel permission
• Factions with hierarchy, tag auto-assignment and 50% relationship inheritance, plus a separate RuntimeFaction system for factions created during play
• .. and an opt-in History log feeding a new Relationship Journal UI.

GC2 integration: 30 Instructions, 18 Conditions and 6 Events, plus an 8-tab editor window (Overview, Relationships, Factions, Entities, Diplomacy, Modifiers, Debugger, Tools) and a UI kit of 8 components / 11 prefabs.

New this cycle:

• A Relationship Journal UI reading the History log (component only — enable History to use it; no prefab ships yet)
• Decay Preview in the Relationships tab that estimates time-to-target in Edit Mode
• JSON export/import of relationship definitions on the Tools tab (Edit-Mode-only, undoable)
• A Gift Preference asset + Apply Gift instruction + On Gift Received event (inventory-agnostic — no Inventory module reference needed)
• gossip/rumour broadcast instruction (Spread Rumour, with falloff and a max-members cap) + On Rumour Spread event
• and a romance-styled Affinity colour palette for the relationship bar UI (reskin only, no new prefab)

Fixed this cycle (build-breaker):

13 NUnit test files were compiled directly into the Runtime assembly, unguarded — Unity strips its test DLL from player builds, so any customer build very likely failed to compile. Tests now live in the correct Tests/Runtime assembly; a real Standalone build now succeeds (0 errors from package code). The Examples installer no longer offers a phantom "update" caused by a version mismatch between the installer descriptor and the installed folder.

Works with: Game Creator 2 (Core) + Visual Scripting — required. GC2 Stats is not required.

Characters and Dialogue are both optional; gifts don't need Inventory.
