Motivation In Udon Sharp, syntactically, the following is nonsensical: var players = new VRCPlayerApi[VRCPlayerApi.GetPlayerCount()]; VRCPlayerApi.GetPlayers(players); Why doesn't GetPlayers() just… return a preconstructed array of players in the instance already? Why do I need to first create an empty array? In Udon Sharp, at least, one can easy replace or initialize an array with something else like so: int[] arrayOfNumbers; void someFunction() { arrayOfNumbers = someClassInstance.AFunctionThatReturnsAnIntArray() } There is no need to preset the size of the array, as the actual array construction is handled by another function. But in the VRCSDK we are required to pass a prebuilt array to this function??? Make it make sense. Solutions One, Update UDON so GetPlayers() no longer requires passing in an empty VRCPlayerAPI[] sized to the number of players when compiled with a newer SDK; The UDON VM would support both the old and the new behavior. This would have the benefit of, at least in UDON Sharp, being syntactically valid, as the initialized VRCPlayerAPI[] would become effectively an optional variable. If passed, it would follow the current behavior. If not passed, the function will create an array sized to the current number of players currently in the instance automatically. Two, create a separate GetPlayerList() , which would return a VRCPlayerAPI[] of the appropriate size (which could then be stored as a variable), and deprecate GetPlayers(VRCPlayerAPI[] players) in favor of the new function. This would have the benefit of easier backwards compatibility and avoid changing default behavior of an existing function.
