Watering Can Items
Items are fairly broad in their types. Each type has it's own properties and uses.
This page is for items that will act as if they were a Watering Can.
Watering Can are all items that have the following line;
"kind": "staxel.item.WateringCan",
This item will water Tiles that have the Tile#"tileStateKind" equal to "staxel.tileState.Dirt" or similar.
Watering Can, currently, do not have any extra components.
Creating a Watering Can Item
Watering Cans are created in the exact same way as Craft Items. In fact you should follow the guide, Items#How to Make a Normal Item, just replace the "kind" property with "staxel.item.WateringCan".
Spawning in a Watering Can Item
Follow the guide at Items#How to Spawn an Item. When that guide mentions "kind", make sure to use "staxel.item.WateringCan" instead of "staxel.item.CraftItem" else you won't be able to spawn the item.
