Define item requirements on parts and check the player’s bag before placement.\ Consume items on build and refund them on destruction. The integration supports two building workflows: #### Building with Pickable Items (Direct Placement) The player picks up bag items scattered in the world. Each bag contains a specific Building Part. The player drags the item to the GC2 hotbar and uses it to enter placement mode directly. One item is consumed per placement. This is the simpler, item-based approach. #### Building with Resources (Hammer + Radial Menu) The player picks up a hammer item. Using the hammer opens the Radial Menu where each slot requires specific resources (wood planks, screws, etc.). If the player has enough resources in their inventory, they can select a part and enter placement mode. Resources are consumed on placement. This is the survival crafting approach. Both workflows can coexist in the same project. {% hint style="info" %} This integration builds on the [Game Creator 2](https://assetstore.unity.com/packages/tools/game-toolkits/game-creator-2-203069) integration and includes all its instructions as well. {% endhint %} *** ### Requirements * [Survival Upgradable](/easy-build-system/extensions/survival-upgradable.md) by Mind Code Interactive * [Game Creator 2](https://assetstore.unity.com/packages/tools/game-toolkits/game-creator-2-203069) by Catsoft Works * [Game Creator 2 Inventory](https://assetstore.unity.com/packages/tools/utilities/inventory-2-game-creator-2-208668) (v2.8.23+) by Catsoft Works {% hint style="warning" %} The demo scene included with the integration uses the Built-in Render Pipeline.\ If your project uses URP or HDRP, materials must be converted to match the pipeline. {% endhint %} *** ### Installation {% hint style="warning" %} [Game Creator 2](https://assetstore.unity.com/packages/tools/game-toolkits/game-creator-2-203069) must be installed before adding the [Game Creator 2 Inventory](https://assetstore.unity.com/packages/tools/utilities/inventory-2-game-creator-2-208668) integration. {% endhint %} {% stepper %} {% step %} ### Install Game Creator 2 Integration Make sure **Easy Build System** and [Game Creator 2](https://assetstore.unity.com/packages/tools/game-toolkits/game-creator-2-203069) are both imported in your project. Open the Hub at: \ `Tools > Mind Code Interactive > Easy Build System > Hub > Integrations`.
Search for the [Game Creator 2 Inventory](https://assetstore.unity.com/packages/tools/utilities/inventory-2-game-creator-2-208668) integration and click **Install Integration**.\ The integration will be imported and the project will recompile. Wait for it to finish. {% endstep %} {% step %} ### Install Game Creator 2 "Adventure" Package Then open the **Game Creator Install** window from the menu:\ `Game Creator > Install...`
Then install the `Adventure` package from [Game Creator 2 Inventory](https://assetstore.unity.com/packages/tools/utilities/inventory-2-game-creator-2-208668).\ The integration's demo scene is built on top of it.
{% endstep %} {% step %} ### Demo Scene Open the demo scene and try it. It's located in:\ `Mind Code Interactive/Easy Build System/Packages/Integrations/GC2 Inventory`
{% endstep %} {% endstepper %} *** ### Creating Your Own Building Items To create a new inventory item linked to a [Building Part](/easy-build-system/reference/building-part.md): 1. Create an Item asset in [Game Creator 2 Inventory](https://assetstore.unity.com/packages/tools/utilities/inventory-2-game-creator-2-208668).\ See the [GC2 Inventory documentation](https://docs.gamecreator.io/inventory/items/) for details on item creation. 2. In the item’s **Usage** section, add `Select Building Item` and assign the [Building Part](/easy-build-system/reference/building-part.md). 3. Create a pickable prefab for the item so the player can find it in the world. *** ### Placeable Items To place a [Building Part](/easy-build-system/reference/building-part.md) directly from the hotbar or inventory, select the item in GC2's Inventory.\ In the **Usage** section, add the `Select Building Item` instruction.\ Set the `Part Prefab Id` to the part you want to place. Here's a screenshot showing this setup on the `Wood Foundation` item included in the demo scene.
When the player uses the item, the system enters placement mode with that part automatically. *** ### Requiring Items To require resources via the Radial Menu, use `GC2BuildingSelectionAction` as the slot action.\ This is different from `BuildingSelectionAction` which selects parts without checking inventory. On each slot, set the **Part Reference** and define the **Required Items** with their amounts.\ You can also configure **Refund Items** to return resources when the part is destroyed. Here's a screenshot showing the setup on the Foundation slot in the demo scene's Radial Menu.
*** ### Tool Item Setup The Radial Menu can require a specific tool item to be equipped before opening.\ In the demo scene, the player must have a **Hammer** in their inventory to access the building menu. On the `GC2RadialMenuIntegration` component attached to the Radial Menu prefab, to configure: **Bag Target:** The player's Bag component. **Requirements Text:** A UI Text element that displays missing requirements. **Required Tool Item:** The GC2 Item that must be in the player's inventory to open the menu.\ Leave empty to allow opening without a tool. **Tool Bag Target:** The Bag to check for the tool item.
