Extending the SandboxApplication classRunning your sandbox for the first time Creating a new Decoda project Configuring Decoda's run executable Creating a sandbox Lua script Creating a floor Adding a light Adding a skybox Adding meshes to the sandbox Creating sandbox objects Shooting blocks Creating an agent Lua script Creating a visual representation Updating an agent position Updating an agent orientation Agent properties Orientation The forward axis The left axis The up axis Location Position Size Height Radius Physics Mass The max force The max speed Speed.
