Where is the rest of the /scoreboard commands in mcpe
Solution 1:
Other objectives have not (yet?) been implemented in minecraft pocket edition. There may be some ways to make the required features "manually" with the dummy soreboard objetive.
For a kill count you could maybe (depending on how you set up your world):
- create a dummy scoreboard objective,
- make sure that everyone spawns at a certain position that they cannot get to otherwise,
- increase the dummy objective for anyone at those coordinates
- teleport them to where they should be.
