Hi,
I need the following scenario:
-
server computes dice total in a timer
-
dice total is replicated with notification
-
on replication notification, client updates its HUD to display the dice total
When the dice total is modified manually, the replication/notification works well.
But as soon as i modify it in a timer, the mecanism doesn’t work any longer.
In the code below:
-
the HUD is updated only on the server.
-
If i put the RealTimeDiceTotal+=1 instruction in any other function than the timer, the client HUD is updated correctly.
So it looks like the replication is not triggered when modified from a timer.
Am i doing anything forbidden ?
Just in case you’re wondering: using a tick is not a solution here: the real computation of RealTimeDiceTotal involves the sum of a large TArray of int32, which would certainly slow things down, hence the use of a timer.
Thanks
