From 70fa30204272e874b8e3acccdc2e22cd4e42b2b2 Mon Sep 17 00:00:00 2001 From: MW Date: Sun, 22 Jul 2007 11:44:36 +0000 Subject: * Some work in progress code: Inventory cache, start of inventory server/service, userprofile cache, inventory handling. (non of it is enabled yet (or at least it shouldn't be). * Fixed some of the problems with crossing regions when flying: you should no longer sink to ground level when crossing (should keep roughly your right height). Should no longer sometimes get sent back to the centre of the current region when attempting to border cross. But instead sometimes you will find you avatar stop at the edge of region and you will need to start moving again to retry the crossing (which should then work). This code is partly based on Babblefrog's issue #212 patch. [I think I have some ideas of how to solve the stopping at edges problem, just want to get the inventory code done first] * Capabilities code has now been moved to the OpenSim.Framework.Communications project as some of the caps code will be tightly tied to inventory/asset handling and it was causing a two way reference problem when it was in its own project/dll. This is a Big commit as I was going to keep my inventory work local until I had it in a working state, in case it brakes anything, but its getting harder to keep in sync with svn. --- .../Communications/Capabilities/LLSDHelpers.cs | 164 +++++++++++++++++++++ 1 file changed, 164 insertions(+) create mode 100644 OpenSim/Framework/Communications/Capabilities/LLSDHelpers.cs (limited to 'OpenSim/Framework/Communications/Capabilities/LLSDHelpers.cs') diff --git a/OpenSim/Framework/Communications/Capabilities/LLSDHelpers.cs b/OpenSim/Framework/Communications/Capabilities/LLSDHelpers.cs new file mode 100644 index 0000000..19ef0c9 --- /dev/null +++ b/OpenSim/Framework/Communications/Capabilities/LLSDHelpers.cs @@ -0,0 +1,164 @@ +/* +* Copyright (c) Contributors, http://www.openmetaverse.org/ +* See CONTRIBUTORS.TXT for a full list of copyright holders. +* +* Redistribution and use in source and binary forms, with or without +* modification, are permitted provided that the following conditions are met: +* * Redistributions of source code must retain the above copyright +* notice, this list of conditions and the following disclaimer. +* * Redistributions in binary form must reproduce the above copyright +* notice, this list of conditions and the following disclaimer in the +* documentation and/or other materials provided with the distribution. +* * Neither the name of the OpenSim Project nor the +* names of its contributors may be used to endorse or promote products +* derived from this software without specific prior written permission. +* +* THIS SOFTWARE IS PROVIDED BY THE DEVELOPERS ``AS IS AND ANY +* EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED +* WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE +* DISCLAIMED.
