From 7923fd29a019eae168b6793ed6e388bc27bc288e Mon Sep 17 00:00:00 2001 From: Arthur Valadares Date: Fri, 21 Aug 2009 21:12:22 -0300 Subject: [PATCH] Adds osDrawPolygon to OSSL. Works a little different then other OS Drawing functions, this one has no start and end point, but a number of points that will form the desired polygon. Only FilledPolygon implemented so far. * Also added some LSL transparent type conversion, as it's done in LSL scripting (string to integer, float to string, etc) --- .../VectorRender/VectorRenderModule.cs | 48 ++++++++++++++----- .../Shared/Api/Implementation/OSSL_Api.cs | 19 ++++++++ .../Shared/Api/Interface/IOSSL_Api.cs | 1 + .../Shared/Api/Runtime/OSSL_Stub.cs | 5 ++ .../Region/ScriptEngine/Shared/LSL_Types.cs | 43 ++++++++++++++--- 5 files changed, 98 insertions(+), 18 deletions(-) diff --git a/OpenSim/Region/CoreModules/Scripting/VectorRender/VectorRenderModule.cs b/OpenSim/Region/CoreModules/Scripting/VectorRender/VectorRenderModule.cs index 2640f08c83..d7f39b0582 100644 --- a/OpenSim/Region/CoreModules/Scripting/VectorRender/VectorRenderModule.cs +++ b/OpenSim/Region/CoreModules/Scripting/VectorRender/VectorRenderModule.cs @@ -469,13 +469,19 @@ namespace OpenSim.Region.CoreModules.Scripting.VectorRender startPoint.X += endPoint.X;
