From f61e54892f2284b6f89bacf3069467c05b2eea11 Mon Sep 17 00:00:00 2001 From: "Justin Clark-Casey (justincc)" Date: Thu, 8 Dec 2011 18:34:23 +0000 Subject: [PATCH] On a new client circuit, send the initial reply ack to let the client know it's live before sending other data. This means that avatar/appearance data of other avatars and scene objects for a client will be sent after the ack rather than possibly before. This may stop some avatars appearing grey on login. This introduces a new OpenSim.Framework.ISceneAgent to accompany the existing OpenSim.Framework.ISceneObject and ISceneEntity This allows IClientAPI to handle this as it can't reference OpenSim.Region.Framework.Interfaces --- OpenSim/Framework/IClientAPI.cs | 6 ++ OpenSim/Framework/IScene.cs | 10 ++- OpenSim/Framework/ISceneAgent.cs | 68 +++++++++++++++++++ .../ClientStack/Linden/UDP/LLClientView.cs | 4 +- .../ClientStack/Linden/UDP/LLUDPServer.cs | 58 ++++++++++------ .../ClientStack/Linden/UDP/Tests/MockScene.cs | 5 +- .../Framework/Interfaces/IScenePresence.cs | 22 +----- OpenSim/Region/Framework/Scenes/Scene.cs | 15 +--- OpenSim/Region/Framework/Scenes/SceneBase.cs | 2 +- .../Region/Framework/Scenes/ScenePresence.cs | 39 +++++++---- .../Server/IRCClientView.cs | 8 ++- .../OptionalModules/World/NPC/NPCAvatar.cs | 5 +- OpenSim/Tests/Common/Mock/TestClient.cs | 7 +- 13 files changed, 171 insertions(+), 78 deletions(-) create mode 100644 OpenSim/Framework/ISceneAgent.cs diff --git a/OpenSim/Framework/IClientAPI.cs b/OpenSim/Framework/IClientAPI.cs index 475fc0150f..a070aa676b 100644 --- a/OpenSim/Framework/IClientAPI.cs +++ b/OpenSim/Framework/IClientAPI.cs @@ -702,6 +702,12 @@ namespace OpenSim.Framework UUID AgentId { get; } + /// + /// The scene agent for this client.
