From 65d595597de9e28ad219d2fbe2326cc99be0e642 Mon Sep 17 00:00:00 2001 From: "E. Allen Soard" Date: Fri, 6 May 2011 18:48:00 -0700 Subject: [PATCH] Adds an optional module to enforce prim limits on a given parcel Takes into account acculmitive prim allowance when multiple parcels are owned by the same avatar on the same region. Does not handle prims that are moved by a script or account for temporary objects at the time of creation. other wise handles all tested cases including: Creating a new object from the build menu Moving an object from another parcel duplicating an object via shift move rezing an object from a script --- .../PrimLimitsModule/PrimLimitsModule.cs | 163 ++++++++++++++++++ 1 file changed, 163 insertions(+) create mode 100644 OpenSim/Region/OptionalModules/PrimLimitsModule/PrimLimitsModule.cs diff --git a/OpenSim/Region/OptionalModules/PrimLimitsModule/PrimLimitsModule.cs b/OpenSim/Region/OptionalModules/PrimLimitsModule/PrimLimitsModule.cs new file mode 100644 index 0000000000..0aee191fac --- /dev/null +++ b/OpenSim/Region/OptionalModules/PrimLimitsModule/PrimLimitsModule.cs @@ -0,0 +1,163 @@ +/* + * Copyright (c) Contributors, http://opensimulator.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 OpenSimulator 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.
