Asset Pointer
When an asset refers to another it does so using an Asset Pointer. These identify the target asset by its GUID.
In *.dat files
Note that the GUID here is not wrapped in quotes because Unturned *.dat files are treated as pairs of strings.
MyAssetPtr ################################
In *.asset files
Two formats are supported in these files. The inline style was added later so you will see the older style used in many official assets.
"MyAssetPtr" "################################"
"MyAssetPtr" { "GUID" "################################" }
In JSON files
"MyAssetPtr": { "GUID": "################################" }
