Example 6 with UpdateSignC2SPacket

use of net.minecraft.network.packet.c2s.play.UpdateSignC2SPacket in project BleachHack by BleachDrinker420.

the class ColorSigns method onPacketSend.

/* This works because the code to strip invalid characters from signs is flawed
	 * because it uses a replaceAll for all the formatting codes instead of matching
	 * all sections symbols, which means you can basically "stack" two formatting
	 * codes ontop of eachother like "&&66", it will when search and find the middle
	 * one and remove it to leave "&6" left which is still a valid formatting code.
	 * Paper has a patch for it to correct it so it doesn't work there */
