In my game if one player summons a rock and uses the shoot move to launch it forward, the other player will see it shoot forward. But if one player summons a rock, and the OTHER player uses the shoot move to launch it forward, the player who summoned the rock won’t see the change apply.
Why is this?
The keyword here is authority or control.
It is really tricky to share object control via the network, so … PUN doesn’t. Only one player actually simulates the object (with scripts, physics, etc) and sends the resulting state to the others, who can look but not affect the object.
Fusion has dedicated servers or can host the simulation on a player’s machine. With that setup it would be easier to affect an object (and have the host/server simulate and update the others).
