Non-Working Example from the Camera Component Manual

HIKOkyoujurou · June 26, 2024, 8:01am

I followed this manual to use camera, write go.set("#camera", "enable") instead of acquire_camera_focus.
However, I got this error.

ERROR:GAMEOBJECT: Properties can not be of type ‘no value’.
ERROR:SCRIPT: main/game/camera/script_camera.script:4: the property ‘enable’ of ‘#camera’ must be a number

Using msg.post("#camera", "enable") works.

It should probably be:

go.set("#camera", "enable", true)

No scratch that. It should be messages like you figured out yourself:

          else if (params.m_Message->m_Id == dmGameObjectDDF::Enable::m_DDFDescriptor->m_NameHash ||
              (dmDDF::Descriptor*)params.m_Message->m_Descriptor == dmGamesysDDF::AcquireCameraFocus::m_DDFDescriptor)
          {
              CameraStackPush(camera->m_World, camera);
          }
          else if (params.m_Message->m_Id == dmGameObjectDDF::Disable::m_DDFDescriptor->m_NameHash ||
              (dmDDF::Descriptor*)params.m_Message->m_Descriptor == dmGamesysDDF::ReleaseCameraFocus::m_DDFDescriptor)
          {
              CameraStackRemove(camera->m_World, camera);
          }

I’ve updated the documentation: Update camera.md · defold/doc@db22edc · GitHub
