Subject: [PATCH] Limit Client Sign length more
|
|
|
|
modified clients can send more data from the client
|
|
to the server and it would get stored on the sign as sent.
|
|
|
|
Mojang has a limit of 384 which is much higher than reasonable.
|
|
|
|
the client can barely render around 16 characters as-is, but formatting
|
|
codes can get it to be more than 16 actual length.
|
|
|
|
Set a limit of 80 which should give an average of 16 characters 2
|
|
sets of legacy formatting codes which should be plenty for all uses.
|
|
|
|
This does not strip any existing data from the NBT as plugins
|
|
may use this for storing data out of the rendered area.
|
|
|
|
it only impacts data sent from the client.
|
|
|
|
Set -DPaper.maxSignLength=XX to change limit or -1 to disable
