From d7cd25ad9c94ee9d0b7e3a8356064f1581be0ff6 Mon Sep 17 00:00:00 2001 From: Fabio Alessandrelli Date: Tue, 15 Jan 2019 08:32:17 +0100 Subject: [PATCH] Save 4 bytes in ENet multiplayer protocol. Avoid sending encoded packet flags (reliable/unreliable/ordered) as that's already been done by ENet itself and we can read them from the incoming packet. --- modules/enet/networked_multiplayer_enet.cpp | 16 +++++++--------- 1 file changed, 7 insertions(+), 9 deletions(-) diff --git a/modules/enet/networked_multiplayer_enet.cpp b/modules/enet/networked_multiplayer_enet.cpp index e53846e2693..196e5920869 100644 --- a/modules/enet/networked_multiplayer_enet.cpp +++ b/modules/enet/networked_multiplayer_enet.cpp @@ -339,11 +339,10 @@ void NetworkedMultiplayerENet::poll() { uint32_t *id = (uint32_t *)event.peer->data; - ERR_CONTINUE(event.packet->dataLength < 12) + ERR_CONTINUE(event.packet->dataLength < 8) uint32_t source = decode_uint32(&event.packet->data[0]); int target = decode_uint32(&event.packet->data[4]); - uint32_t flags = decode_uint32(&event.packet->data[8]); packet.from = source; packet.channel = event.channelID; @@ -364,7 +363,7 @@ void NetworkedMultiplayerENet::poll() { if (uint32_t(E->key()) == source) // Do not resend to self continue; - ENetPacket *packet2 = enet_packet_create(packet.packet->data, packet.packet->dataLength, flags); + ENetPacket *packet2 = enet_packet_create(packet.packet->data, packet.packet->dataLength, packet.packet->flags); enet_peer_send(E->get(), event.channelID, packet2); } @@ -378,7 +377,7 @@ void NetworkedMultiplayerENet::poll() { if (uint32_t(E->key()) == source || E->key() == -target) // Do not resend to self, also do not send to excluded continue; - ENetPacket *packet2 = enet_packet_create(packet.packet->data, packet.packet->dataLength, flags); + ENetPacket *packet2 = enet_packet_create(packet.packet->data, packet.packet->dataLength, packet.packet->flags); enet_peer_send(E->get(), event.channelID, packet2); } @@ -497,8 +496,8 @@ Error NetworkedMultiplayerENet::get_packet(const uint8_t **r_buffer, int &r_buff current_packet = incoming_packets.front()->get(); incoming_packets.pop_front(); - *r_buffer = (const uint8_t *)(¤t_packet.packet->data[12]); - r_buffer_size = current_packet.packet->dataLength - 12; + *r_buffer = (const uint8_t *)(¤t_packet.packet->data[8]); + r_buffer_size = current_packet.packet->dataLength - 8; return OK; } @@ -543,11 +542,10 @@ Error NetworkedMultiplayerENet::put_packet(const uint8_t *p_buffer, int p_buffer } } - ENetPacket *packet = enet_packet_create(NULL, p_buffer_size + 12, packet_flags); + ENetPacket *packet = enet_packet_create(NULL, p_buffer_size + 8, packet_flags); encode_uint32(unique_id, &packet->data[0]); // Source ID encode_uint32(target_peer, &packet->data[4]); // Dest ID - encode_uint32(packet_flags, &packet->data[8]); // Dest ID - copymem(&packet->data[12], p_buffer, p_buffer_size); + copymem(&packet->data[8], p_buffer, p_buffer_size); if (server) {
