The updated screenshot has input_redundancy and input_batch_count in the same project settings, because godot 4.1 doesn't hot-reload a plugin's variables, so a rename shows the same variable 2 times in 4.1 until you reload the project

As for is_fresh, I think it triggers only once a (rewindable) node starts rollback, so for activating weapon SFX, it works only if you place it on the projectile itself

Example code of forest brawler

func _rollback_tick(delta: float, tick: int, is_fresh: bool):
	# Respawn
	if tick == respawn_tick:
		_snap_to_spawn()
		velocity = Vector3.ZERO
		last_hit_tick = -1
		
		if is_fresh:
			GameEvents.on_brawler_respawn.emit(self)

Good catch @TheYellowArchitect . Screenshot updated!

is_fresh is definitely always true when a tick is first processed as its set and emitted from _process_tick.

flow is here: https://foxssake.github.io/netfox/netfox/guides/network-rollback/

I did some testing on both a single and multi client game and they worked as expected.

Observed by adding a log line at the start of a rollback tick function

print("peer: ", str(multiplayer.get_unique_id()), " - node: " ,name, " processing tick ", str(tick), " is fresh " , str(is_fresh))

Added a minor commit, wrapping docs to 80 chars. I'll have to document this convention somewhere 🙂

Not approving yet, due to the naming thing with #252

@elementbound removed the screenshot on this one to unblock

@albertok kudos!
