# Resource node (Crystal Node)
## Step 1 (Asset)
To create **new resource node** we must first create an `EntitySO` data set with **capabilities**, before we create a prefab.
1. Select **Resource Node** type
2. Click **Create New** button
3. Set desired **name** and **description** of the resource node
4. **Cost** can be ignored here;
5. Select **Capabilities** tab
1. With capabilities you add configuration for behaviours added to the entity/unit or modules managing them
6. Set node's **resource** and it's **quantity**

## Step 2 (Prefab)
After data asset is created, we can proceed with creating a prefab:
1. Click on the **Create Prefab** button if you wish for prefab to be created automatically. If you use existing prefab, drag it in the **associated prefab** field and click **Update Prefab** instead. This step attaches (does not remove) any components required by defined capabilities themselves. Any other additional scripts we can add on the prefab directly.
2. Now click **Open Prefab** to and open **Scene** window to see it.
3. **Configure visuals** as desired, by default a primitive cube model is present.
4. **Add collider** to the **root game object**, primarily for selection and other potential raycasts your systems may be performing (such as navigation avoidance).
5. **Set Layer** of the root object (the one with collider) which is used for selection.
**Optional**
1. **Add Obstacle** for your navigation system, so units avoid the object.
2. **Add Static Interaction Position Provider**, a component which generates pre-defined positions for interacting with an object. This is useful only if you have no collision avoidance in your navigation and purely rely on direct destinations to interact.

## Step 3 (Collector)
Either you have your own collector set up or you are using the provided worker included in the demo, make sure that the **resource collector capability** supports this resource. If supported resources array is **empty**, then all resources are supported; otherwise only listed ones can be collected.
