• Entity commands, casted_on

Posted: **Fri Feb 23, 2018 4:32 am**

when you walk up to a banker and click him he opens the bank windows ( as it should)
on live he will also talk to you (as if you pressed hail)(on live not sure in emu)

what it doesnt do when bank is selected is trigger casted on like other spawn types

am i missing soemthing or would we just have to add something to the client bank code to taht casted_on or something else in the spawn script whould get triggerred

what i envision walk up to a bank and
click bank, bank opens but then also have him talk to us via spawn script "Hello Ememjr, welcome to my bank"
of click Guild Bank, guild bank opens and he says "Hello Ememjr, welcome to the Persevernce Guild Bank"
but we could script what ever we wanted quest updates, etc

i thought i saw a thread about this type of thing before but cannot find it now

the way the client works as we know when you click on an NPC the primary command is executed,
via the OP_EntityVerbsVerbMsg opcode/packet
what our code does here is first it looks to see if its one of our "commands" (such as bank)

if it is bank or one of our other commands then it ( on an npc) it does

Code: Select all

commands.Process(handler, &command, this);

but

it will then not do

Code: Select all

(NPC*)spawn)->HandleUse(this, command.data)

which actually handle the custom entity commands

since the custom entitiy commands are handle by casted_on i the script it does not seem to hurt to remove the else from this

Code: Select all

if(spawn && spawn->IsNPC()){
								command = packet->getType_EQ2_16BitString_ByName("command");
								//if (EntityCommandPrecheck(spawn, command.data.c_str())){
									if (!((NPC*)spawn)->HandleUse(this, command.data)){
										LogWrite(WORLD__ERROR, 0, "World", "Unhandled command in OP_EntityVerbsVerbMsg: %s", command.data.c_str());
									}

so now if i click on a banker and use casted_on in the script it will execute even if the primary command is a command like bank
where as before it would only do one or the other

Code: Select all

case OP_EntityVerbsVerbMsg:{
			LogWrite(OPCODE__DEBUG, 1, "Opcode", "Opcode 0x%X (%i): OP_EntityVerbsVerbMsg", opcode, opcode);
			PacketStruct* packet = configReader.getStruct("WS_EntityVerbsVerb", GetVersion());
			if(packet){
				packet->LoadPacketData(app->pBuffer, app->size);
				int32 spawn_id = packet->getType_int32_ByName("spawn_id");
				player->SetTarget(player->GetSpawnWithPlayerID(spawn_id));
				Spawn* spawn = player->GetTarget();
				if (spawn && !spawn->IsNPC() && !spawn->IsPlayer()){
					string command = packet->getType_EQ2_16BitString_ByName("command").data;
					if (EntityCommandPrecheck(spawn, command.c_str())){
						if (spawn->IsGroundSpawn())
							((GroundSpawn*)spawn)->HandleUse(this, command);
						else if (spawn->IsObject())
							((Object*)spawn)->HandleUse(this, command);
						else if (spawn->IsWidget())
							((Widget*)spawn)->HandleUse(this, command);
						else if (spawn->IsSign())
							((Sign*)spawn)->HandleUse(this, command);
					}
				}
				else{
					EQ2_16BitString command = packet->getType_EQ2_16BitString_ByName("command");
					if(command.size > 0){
						string command_name = command.data;
						if(command_name.find(" ") < 0xFFFFFFFF)
							command_name = command_name.substr(0, command_name.find(" "));
						int32 handler = commands.GetCommandHandler(command_name.c_str());
						if(handler != 0xFFFFFFFF){
							if(command.data == command_name){
								command.data = "";
								command.size = 0;
							}
							else{
								command.data = command.data.substr(command.data.find(" ")+1);
								command.size = command.data.length();
							}
							commands.Process(handler, &command, this);
						}
						//else{
							if(spawn && spawn->IsNPC()){
								command = packet->getType_EQ2_16BitString_ByName("command");
								//if (EntityCommandPrecheck(spawn, command.data.c_str())){
									if (!((NPC*)spawn)->HandleUse(this, command.data)){
										LogWrite(WORLD__ERROR, 0, "World", "Unhandled command in OP_EntityVerbsVerbMsg: %s", command.data.c_str());
									}
								//}
							}
							else
								LogWrite(WORLD__ERROR, 0, "World", "Unknown command in OP_EntityVerbsVerbMsg: %s", command.data.c_str());
						//}
					}
				}
				safe_delete(packet);
			}
			break;

I will commit this as long as i dont run into any issues with it

ok one issue with this so far, if the command in bank or a completely custom entity that there is no /command for then it works ok

if there is a /command and entity command for it such as hail , then hail executes twice not sure if we have a way around that other than doing an if that will skip the second version on certain entities ie hail
