Sync Child/Parent relationships with MLAPI

Sync Parent/Child Relationship

Since the Network Transform does not sync the parent/child relationship I chose to implement this with a Client RPC call. But the game objects do not share their unique instance identifiers across networked machines. So how can the server say to the client, “You must parent X to Y”? Whilst Unity may not have a guaranteed identifier, MLAPI does share the network object Id. When Id 99 is created for object X on the server, then all the clients will have an object X with Id 99. Since the enemy object we are spawning already has a Network Object, the missing part of the puzzle is to ensure that the Parent also has an Network Object.

Logram Firing

The Logram plays an animation of its turret opening and a bullet emerging from it. The bullet only emerges at a certain point within the animation track. This is achieved with using an Animation Signal. However, animation signals are not synchronised with MLAPI. Not to worry, we “just” need to add another RPC call.

  1. The bullets are not yet shared.
  2. Currently each Logram only knows about the local player. Therefore the Lograms for Player 1 fire at Player 1, the Lograms for Player 2 fire at Player 2.
