Attach Flags
Attach Flags are used as settings for an attachment of one thing to another.
AttachThingToThing() attaches a thing
to a base thing with a 0x4 attachment. AttachThingToThingEx()
also creates a 0x4 attachment, but allows you to add flags to the attachment with the third parameter. The "Used with"
category is added to clarify that 0x4 is always used with a thing to thing attachment.
You may also use SetThingAttachFlags(),
ClearThingAttachFlags(), and
GetThingAttachFlags() to work with
Attach Flags. But be careful, manually setting and clearing these flags can crash the game.
