@valve I know we have access to keyvalues, but it's very limiting in terms of what we can do. May we also have access to netprops and usermessages too? :) Then I no longer need to require my users to have SourceMod or hammercode installed. Thank you!

func_nav_blocker entity to block specific enemies.
Write a script to fire OnTouch of a trigger_multiple. Get the entity's classname. If the entity's classname is NOT "witch" && GetZombieType() is NOT tank && ent index > 4 then get the ent's forward vector, normalize the forward vector, scale the vector, and negate the vector and set its velocity vector to the result. That's how I would do it, since many brushes aren't networked, but trigger_multiple is :P As for turning the block on and off, just use a global boolean flag and set that to true/false.

Entities 1 through g_pGlobals->maxClients (numbers are inclusive) are client entities. You can't really "delete" them. You can have the engine kick them from the game (including bots). They can spawn more than once.

If you want an identifier that doesn't change, use an entity reference (like you did). When you get an index from reference, just make sure that the ref is still valid and the index is greater than 0.
@shotgunefx: Ah, that's a good concmd to know :) As for the c++ function, it retrieves an integer netprop and pushes the value back onto the Lua stack.

@The Fish: If you change teams, SurvivorBot::Spawn() seems to fire again (and over and over again for infected), but the event player_first_spawn does not. You are correct in your reasoning that the client entities are created once.

Originally posted by shotgunefx:
You can hook player_spawn, and also player_first_spawn. As far as usable props, most of the stuff that's new so far works in both regular campaigns and mutations, but in my tests, it "seems", not CanPickupObject(). Though you can just hook player_use and manage it that way.

Technically, we are not hooking a function unless we can modify or augment the outcome of the function. From what I've been told, we cannot modify the game event params (please confirm), but rather just "listen" for them.

Also, from what I can see in my modevents.res, there is no player_spawn, but there is a player_first_spawn, but I still have the older non-beta L4D2 installed. IMO, it's still not as solid as a hook to SurvivorBot::Spawn(), because I have seen instances where the event is never broadcasted (during my long hours of SM and HC modding). To prevent items from being picked up dynamically, I've always hooked CBaseEntity::Use(), and I have no idea if that can be done in EMS (maybe there is an alternative way or workaround, perhaps CanPickupObject). It would be helpful if Valve provided us modders with more hooks. For example, CTerrorPlayer::Weapon_CanUse(), NextBotPlayer<CTerrorPlayer>::Weapon_Equip(), SurvivorBot::Weapon_Switch() to name a few more. Again, there may be a workaround for these. I am just naming some that I have hooked in my c++ server plugin that I couldn't find with vscripts. Lastly, getting and setting netprops, e.g. sample function from my c++ valve server plugin (VSP):


static int GetEntityPropInt(lua_State* L) { OUTPUT_FUNC; edict_t* edict = CheckEntity(L, 1); if (!edict) { lua_pushnumber(L, -1); return 1; } CBaseEntity* ent = g_HCBase->EdictToBaseEntity(edict); if (!ent) { lua_pushnumber(L, -1); return 1; } IServerUnknown* pUnk = (IServerUnknown*)ent; IServerNetworkable* pNet = pUnk->GetNetworkable(); if (!pNet) { lua_pushnumber(L, -1); return 1; } char* prop = const_cast<char*>(luaL_checkstring(L, 2)); char* serverclass = const_cast<char*>(pNet->GetServerClass()->GetName()); int intval = g_HCBase->GetPropertyInt(serverclass, prop, edict); lua_pushnumber(L, intval); return 1; } int HammerCodeBase::GetPropertyInt(char* pClassname, char* pNetProp, edict_t* pEdict) { CBaseEntity* pEntity = EdictToBaseEntity(pEdict); if (!pEntity) return -1; int element = 0; int bit_count = 0; bool isDataMap = false; int size = 4; int offset = Base_FindOffset(pClassname, pNetProp, pEntity, &bit_count, &element, &isDataMap); if (!offset) return -1; bool is_unsigned = false; if (!isDataMap) { Vector data = GetBitCountData(pClassname, pNetProp, pEntity, offset); bit_count = data[0]; is_unsigned = (bool)data[3]; } // Credits for this last part go to SM if (bit_count < 1) bit_count = size * 8; if (bit_count >= 17) return *(int32_tr *)((uint8_tr *)pEntity + offset); else if (bit_count >= 9) { if (is_unsigned) return *(uint16_tr *)((uint8_tr *)pEntity + offset); else return *(int16_tr *)((uint8_tr *)pEntity + offset); } else if (bit_count >= 2) { if (is_unsigned) return *(uint8_tr *)((uint8_tr *)pEntity + offset); else return *(int8_tr *)((uint8_tr *)pEntity + offset); } else return *(bool *)((uint8_tr *)pEntity + offset) ? 1 : 0; }


I personally cannot think of any rational way of coding a function like that running off Squirrel VM :P It would be highly appreciated to have a method to modify netprops in our scripts. Maybe a wrapper function for IVEngineServer::UserMessageBegin() too! :)
Yes indeed. See my map:

An EntitySpawned and PlayerSpawned callback would be awesome. Just like in SourceMod and HammerCode. I can think of over two dozen cool things to do with them. That, along with netprops and usermessages, and my cries would be heard.

Mutation: Tank Slayer
If you're planning on testing it, count me in! Add me
Wow, this is really cool! Well done!
