Example 2 with Packet

use of net.minecraft.network.Packet in project MinecraftForge by MinecraftForge.

the class FMLEmbeddedChannel method generatePacketFrom.

/**
     * Utility method to generate a regular packet from a custom packet. Basically, it writes the packet through the
     * outbound side which should have a message to message codec present (such as {@link FMLIndexedMessageToMessageCodec},
     * transforming from mod packets to standard {@link FMLProxyPacket}s.
     *
     * This is mostly useful in cases where vanilla expects a packet, such as the TileEntity getDescriptionPacket.
     *
     * @param object The inbound packet
     * @return A Packet suitable for passing to vanilla network code.
