From 9ffe4d850e9ccf2fc40901e186af3d38c31b9a6d Mon Sep 17 00:00:00 2001 From: Alan Webb Date: Mon, 3 Aug 2009 21:43:08 -0400 Subject: This change adds support for the attach event in scripts. [1] Added a new OnAttach event to Scene/EventManager [2] Hooked up existing attach event handler in XEngine. [3] Modified SceneGraph and Scene.Inventory to trigger attach events at the appropriate places. I was forced to distribut the changes across two files because of the way attach processing is distributed across the two files. [4] In the case of RezSingleAttachmentFromInventory it is necessary to handle event scheduling in a special way. There is no synchronous path available, so the fact that this object is attached, and who it is attached to, is cached when the ScriptInstance is created. When the script is started, the attached handler is driven after on_rez (but before changed, this should be reviewed).
