I downloaded the source and did some searching. I mention this below, too, but it looks like size gets casted into an int as it's placed as a parameter into SendAppearancePacket().
Found it in mob.h
As taken from mob.cpp:
Code:
1157 void Mob::ChangeSize(float in_size = 0, bool bNoRestriction) {
1158 //Neotokyo's Size Code
1159 if (!bNoRestriction)
1160 {
1161 if (this->IsClient() || this->petid != 0)
1162 if (in_size < 3.0)
1163 in_size = 3.0;
1164
1165
1166 if (this->IsClient() || this->petid != 0)
1167 if (in_size > 15.0)
1168 in_size = 15.0;
1169 }
1170
1171
1172 if (in_size < 1.0)
1173 in_size = 1.0;
1174
1175 if (in_size > 255.0)
1176 in_size = 255.0;
1177 //End of Neotokyo's Size Code
1178 this->size = in_size;
1179 SendAppearancePacket(AT_Size, (int32) in_size);
1180 }
It looks like it's being casted as an int once it calls SendAppearancePacket.
This also exists in mob.h
Code:
1117 void Mob::SendAppearancePacket(int32 type, int32 value, bool WholeZone, bool iIgnoreSelf, Client *specific_target) {
1118 if (!GetID())
1119 return;
1120 EQApplicationPacket* outapp = new EQApplicationPacket(OP_SpawnAppearance, sizeof(SpawnAppearance_Struct));
1121 SpawnAppearance_Struct* appearance = (SpawnAppearance_Struct*)outapp->pBuffer;
1122 appearance->spawn_id = this->GetID();
1123 appearance->type = type;
1124 appearance->parameter = value;
1125 if (WholeZone)
1126 entity_list.QueueClients(this, outapp, iIgnoreSelf);
1127 else if(specific_target != NULL)
1128 specific_target->QueuePacket(outapp, false, Client::CLIENT_CONNECTED);
1129 else if (this->IsClient())
1130 this->CastToClient()->QueuePacket(outapp, false, Client::CLIENT_CONNECTED);
1131 safe_delete(outapp);
1132 }
Following in_size, which turned into value, we go to appearance, which is a spawnappearance_struct, located in common\eq_packet_structs.h
Code:
445 /*
446 ** SpawnAppearance_Struct
447 ** Changes client appearance for all other clients in zone
448 ** Size: 8 bytes
449 ** Used in: OP_SpawnAppearance
450 **
451 */
452 struct SpawnAppearance_Struct
453 {
454 /*0000*/ uint16 spawn_id; // ID of the spawn
455 /*0002*/ uint16 type; // Values associated with the type
456 /*0004*/ uint32 parameter; // Type of data sent
457 /*0008*/
458 };
Lastly, though it doesn't look like it would be involved, the mentioned OP_SpawnAppearance occurs in common\eq_opcodes.h, where it defines opcodes for zone.exe's login sequence.
Code:
#define LiveOP_SpawnAppearance 0x012F // Sets spawnid/animation/equipment
