Node-based, event-driven crafting that happens in the world, not in menus. Hit, heat, crush, combine — define recipes as visual graphs and let the world transform itself.World Craft Graph turns crafting from a menu interaction into a physical world event. The player doesn't open an interface — they hit, crush, heat, combine. As a developer, you describe the rules of those transformations as a visual graph, without writing a single line of code.The ideaDrop three stones next to each other. Hit them with a sledgehammer. If the conditions match, the stones disappear and a stone slab appears in their place. This isn't a hand-written script. It's a graph of rules that fires because the world dispatched an impact event, the system found a matching recipe, and applied it.That's how all crafting works in World Craft Graph: rules instead of recipes, the world instead of menus, events instead of buttons.FeaturesVisual graph editor. A full node editor with node categories, search, validation, and clear execution tracing.Event-driven architecture. Impact, tool use, placement, heating, crushing, mixing, ignition, timers, custom events — all extensible.Flexible item model. ScriptableObject definitions, runtime components, dynamic properties, timed states, tags.Rich node palette. Queries, filters, conditions, logic, modifiers, actions, outputs — everything needed for non-trivial recipes.Conflict resolution. When multiple graphs match an event, the system picks by priority or specificity — strategies are extensible.Extensibility API. Add your own event, condition, modifier and action nodes without touching the core.Debugging out of the box. Execution tracing answers: which graph ran, why, where it failed, which items were selected.Demo scenes and ready-made recipes. Stone slab, herb powder, primitive axe and more.Who it's forSurvival and crafting games where crafting is an action in the world, not a journal entry.Immersive sims where items react to tools and physics.Sandboxes where players discover recipes through experimentation.Any project where the game designer needs to author rules directly, without a programmer in the loop.It's a focused rule-based world transformation system — built for one job and built to do it at a level that usually takes months of custom code.Features:Visual node graph editor. UI Toolkit-based editor with a node palette, inspector, validation, reachability tracer, undo/redo, and a play-mode debugger that highlights the currently executing node.Event-driven runtime. 23 typed world events out of the box: impact, tool use, heat, item placement, interaction, custom payloads, gestures, collisions, hooks.~70 stock nodes. Triggers, requirements, stages, logic, data, modifiers, outputs, control and meta categories — covering non-trivial recipes without code.Item system. ScriptableObject definitions and a WorldCraftItem runtime component with properties, parameters, timed states, quality, stacking and physical auto-deposit into nearby slots.Workstations. Scene objects with slots, state machines and an optional thermal simulation (furnace), authored as graphs and registered automatically.Sub-graphs. Reusable rule chains via CraftSubGraphAsset — share logic across recipes.Conflict resolution. Multiple matching graphs are resolved by priority or specificity; the strategy is extensible.Extensibility API. Add custom event, condition, modifier, action and data-type nodes via attributes — no core edits required.Management Hub. 7-tab dashboard for items, recipes, sub-graphs, workstations, validation and tools.Debug & tracing. Execution traces answer which graph ran, why, where it failed and which items were selected.Rich samples. 25 sample recipes, a Custom-Node Kit with 10+ ready-made nodes, a custom-data-type example, and a showcase scene with player, HUD and recipe dashboard.Clean architecture.
