This is my first plugin, I did it because I needed that for my 12-survivor server, but I think anyone can benefit from this and help me improving this plugin.

Description:
All weapons and health items will have their max times they can be used by multiple players override by the desired amount, if the amount is set to 0 the weapon/item will be deleted from map.

Usually, on servers with 5+ survivors the weapons in the saferoom or in the spawnzone are not enough for everybody, usually some players end without weapons, or forced to grab a weapon that they dont like because they have no other option. Also there are some servers with 1 weapon per spot, so the first grabs the weapon is the only who gets it, this plugin fits both situations. With this plugin there can be weapons and health items for everyone. Also weapon number can be decreased or removed to make game harder.

Since v1.3 this plugin can modify weapons spawned in midgame, modifying medkits generated by director on Normal difficulty and any other weapon/item created by other plugins.

A mix of old and new syntax.

Sorry, for that, I learned how to write in sourcepawn basically from the Wiki, some questions answered on these forums (some of them really old probably) and looking inside some .sp plugins to see how the author did wrote that, so the syntax is a mix of everything I looked, where is a good post/page with how to write with modern syntax?

I uploaded the .smx file, you can download it now compiled.

[Shadowysn]

Converted to new syntax + edited some stuff.
(Absolutely haven't tested this yet, something might've been screwed up, but its highly unlikely.)

ALSO, go into the full-edit page of your main plugin post and check compiler version. If I'm correct, the compiler's been changed to 1.1, which is absolutely the wrong version, hence your plugin not compiling from the .sp file.
Changing back to 1.10 will just have it revert to 1.1 again.
Choose an older compiler version like 1.8, which I've tested and worked for my plugin.

Yeah, the compiler is now 1.8, it works fine. Everytime I press the preview post button, the compiler needed, description, ect are set to blank/defult. I will add the changes on next version (I'm looking how to manipulate that medkits placed around the map without modifying kits being carried by survivors, as long they are the same entity).

Oh yeah, have you made sure the entity names of the medkits placed around the map are weapon_first_aid_kit?
Look at them and type in ent_remove. This'll remove the entity and print out it's targetname as well as it's classname.
It could potentially be weapon_item_spawn.

Yeah, they are, in easy, normal, and hard difficulty director can convert some pills and adrenaline spawn into a first aid kit, but instead of making a weapon_first_aid_kit_spawn, is a weapon_first_aid_kit. You can notice that if at the beggining of the map using report_entities command in console, if you see "weapon_first_aid_kit" in the console log, and the total count is higher than the number of medkits carried by players, there is one medkit on the map, I noticed that random medkits are not affected by my plugin, so the only entity is not afected is that one. Usually you can have 1-2 medkits at the map, so the idea is to manipulate those kits, convert into weapon_first_aid_kit_spawn and then manipulate them like the medkits in the saferoom, or directly delete them.

Alright, then you can check the m_hOwnerEntity netprop of the medkit entity using GetEntPropEnt, and not do anything to the medkit if the netprop has a valid player.

PHP Code:

bool IsInPlayerInventory(int entity)
{
    if (!IsValidEntity(entity)) return false;
    int owner = GetEntPropEnt(entity, Prop_Send, "m_hOwnerEntity");
    if (IsValidClient(owner)) return true;
    return false;
}

bool IsValidClient(int client, bool replaycheck = true) // This is for convenience
{
    if (!IsValidEntity(client)) return false;
    if (client <= 0 || client > MaxClients) return false;
    if (!IsClientInGame(client)) return false;
    if (replaycheck)
    {
        if (IsClientSourceTV(client) || IsClientReplay(client)) return false;
    }
    return true;
} 


EDIT: Oh, also, if you're not using the event parameters, you can safely use EventHookMode_PostNoCopy. Kinda forgot to put them in the new-syntax version.

PHP Code:

    HookEvent("round_end", Event_Round_End, EventHookMode_PostNoCopy);
    HookEvent("player_spawn", Event_Player_Spawn, EventHookMode_PostNoCopy); 


An example snippet from my FirstAid_Manager plugin that uses the event parameters:

PHP Code:

public void player_spawn(Handle event, const char[] name, bool dontBroadcast)
{
    //PrintToServer("%s plugin detected event: %s", PLUGIN_NAME_SHORT, name);
    if (!hasRoundEnded) return;
    
    int clientID = GetEventInt(event, "userid");
    int client = GetClientOfUserId(clientID);
    if (!IsValidClient(client) || !IsSurvivor(client)) return;
    
    hasRoundEnded = false;
    
    ManageFirstAidFunction();
} 


Here's a list of lists for games and their events:

Lets just ignore that random medkits for now, it seems it only happens sometimes in L4D1 maps. L4D2 maps spawn randomly weapon_first_aid_kit_spawn instead. And now while im trying to check if the plugin gets the random medkits spawned around the map only finds player carrying medkits it seems there are no weapon_first_aid_kit at the beggining of the map and does not remove them fortunately.

I though that random medkits were spawned at the beggining of the round, but maybe the director decides to change pain pills into medkits if survivors are finding hard to progress in normal/advanced difficulty. I will keep cheeking that.

What I will try to do is to manage weapon spawns, getting separating them in weapon types, pistols, autoshotguns, smgs, rifles ect. Also Ill try to add to the list explosive and incendiary ammo (maybe people want to remove them from their server or allow to pick more than once).

So for now I will not include the last code, but may be useful in further versions or with any other plugin, thanks for the help anyway Shadowysn. Also thanks for the fixed code with new syntax, I`m rewriting the plugin, I will have the new version soon.
