Steps (without Worldsmith)
Adding a world item
Make sure the item you want to use can be a world item.
Choose where you would like to have the world item in-game, writing down the screen number, X and Y positions.
Open the worlditems xml configuration file located in props/worlditems.
Paste it below the closing tag of an already existing WorldItemState or below the items tag.
Replace YOUR_ITEM_NAME with the Item name in the item’s list.
Replace YOUR_WORLDITEM_SCREEN with the screen of your choice.
Replace YOUR_WORLDITEM_X_POSITION and YOUR_WORLDITEM_Y_POSITION with their own respective relative value.
The world item should be now available like so:
In the following example, the item name is Silver. Here’s a preview of my silver’s count before collecting the item:
After interacting with it, the item will disappear from the world and it should:
spawn a Silver coin in your inventory if you didn’t have one beforehand
add one Silver coin to the Silver coin count
If the item wouldn’t it be stackable and you already had an item present in the inventory, nothing will change in the inventory.
Removing a world item
Open the worlditems xml configuration file located in props/worlditems.
Find the item you want to delete.
Remove the entire WorldItemState tag of the world item that you don’t like.
Personalizing a world item (optional)
In the same folders where you found the worlditems xml configuration file you can find some packed XNB files. Each file corresponds to the texture of the world item.
By replacing any of these, you will change the look of your world item.
