OpenSim​/llGroundSet

llGroundSet(int x, int y, double height), llGroundUpdate()

OS Function に同じような osTerrainSetHeight(), osTerrainFlush() があった．

• llGroundSet(): 座標 (x, y) の標高を height にする関数．
• llGroundUpdate(): 変更した標高を適用させる．
• OpenSim/Region/ScriptEngine/Shared/Api/I​mplementation/LSL_Api.cs

         // Fumi.Iseki
         public void llGroundSet(int x, int y, double height)
         {       
             m_host.AddScriptLPS(1);
                 
             if (World.Permissions.CanTerraformLand(m_host.OwnerID, new Vector3(x,y,0)))
             {
                 if (x>=World.Heightmap.Width)  x = World.Heightmap.Width - 1;
                 else if (x<0) x = 0;
                 if (y>=World.Heightmap.Height) y = World.Heightmap.Height - 1;
                 else if (y<0) y = 0; 
                 World.Heightmap[x, y] = height;
             }
         }

             if (tm != null)
             {
                 tm.TaintTerrain();
             }
         }

• OpenSim/Region/ScriptEngine/Shared/Api/R​untime/LSL_Stub.cs

         // Fumi.Iseki
         public void llGroundSet(int x, int y, double height)
         {
             m_LSL_Functions.llGroundSet(x, y, height);

         }

• OpenSim/Region/ScriptEngine/Shared/Api/I​nterface/ILSL_Api.cs

  void llGroundSet(int x, int y, double height);
  void llGroundUpdate();

別解：TerrainModule.cs に　SetHeightMap() 関数を追加する場合

• OpenSim/Region/ScriptEngine編集/Shared/Api/Implementation/LSL_Api.cs

             m_host.AddScriptLPS(1);
                 
             if (World.Permissions.CanTerraformLand(m_host.OwnerID, new Vector3(x,y,0)))

                 if (tm != null)
                 {

                     tm.SetHeightMap(x, y, height, m_host.OwnerID);
                 }
             }
         }

  • チェックが２重だな
