The item_instance data blob field demystified

Hello,

For a long time, the item_instance "data" blob field has been some mystery. In this post, I will describe the update that we need to do on the wiki to solve this misunderstanding:

The data-field is a String separated by spaces between each values. Here's the value meaning sorted by index:

1. Item GUID

2. Item High GUID (Stored 0x4000 0000)

3. Object Field Type (Mask value retrieved from the code: TypeMask enum, value is 3 or 7 depending if it's an item or a container)

4. Item Entry (Entry ID of the item_template)

5. Scale (Scale value, did not yet found the storage type, maybe float ?)

6. Padding (No info on this)

7. Owner Guid

8. High Guid Owner (Should be always 0 for player)

9. Item Field Contained (Can be the GUID of another item instance if stored in a bag or the GUID of the character if equipped)

10. Item Field Container High Guid (Should be 0x4000 0000 or 0 depending if it's a bag or if it's a player)

11. Creator GUID
