PHP Code:

Working on a plugin for Custom Weapons 2 to limit the level that an engineer can upgrade his buildings to. I'm trying to prevent a building from being built. Here's the code:

//used when "max building level" is set to 0. Returns Plugin_Handled, which blocks the building from being built
public Action Event_PreBuild(Event event, const char[] name, bool dontBroadcast)
{
    PrintToServer("Inside EventPreBuild");
    int builderID = GetEventInt(event, "userid", -1);
    int clientIndex = GetClientOfUserId(builderID);
    int buildingID = GetEventInt(event, "index", -1);
    char buildingClassname[64];
    GetEntityClassname(buildingID, buildingClassname, sizeof(buildingClassname));
    PrintToServer("%d", builderID);
    PrintToServer("%d", clientIndex);
    
    if(clientIndex != -1)
    {
        PrintToServer("playerisvalid");
        PrintToServer("%d", hasMaxBuildingLevel[clientIndex]);
        PrintToServer("%d", clientIndex);
        if(hasMaxBuildingLevel[clientIndex] == true)
        {
            PrintToServer("playerhasmaxbuilding");
            if(buildingID != -1)
            {
                PrintToServer("validBuilding");
                PrintToServer("%s", buildingClassname);
                if(strcmp(buildingClassname, "obj_attachment_sapper", false) != 0)
                {
                    PrintToServer("not sapper");
                    if(!strcmp(buildingClassname, "obj_sentrygun", false)) //strcmp returns 0 if strings are equal
                    {
                        PrintToServer("Building is sentry");
                        PrintToServer("%d", maxBuildingLevel[clientIndex][0]);
                        if(maxBuildingLevel[clientIndex][0] == 0)
                            return Plugin_Handled;
                    }
                    else if(!strcmp(buildingClassname, "obj_dispenser", false))
                    {
                        if(maxBuildingLevel[clientIndex][1] == 0)
                            return Plugin_Handled;
                    }
                    else if(!strcmp(buildingClassname, "obj_teleporter", false))
                    {
                        if(maxBuildingLevel[clientIndex][2] == 0)
                            return Plugin_Handled;
                    }
                }
            }
        }
    }
    return Plugin_Continue;
} 


It's getting all the way to inside if(!strcmp(buildingClassname, "obj_sentrygun", false)) //strcmp returns 0 if strings are equal

But "return Plugin_Handled;" either isn't working or it's not successfully blocking the event. Anyone know what might be going on?

Use EventHookMode_Pre as the 3rd parameter under HookEvent.

That being said, I don't think that would block the building from being built. That would just block the event from being transmitted. There is probably a player command being sent to the server that says the client is dropping a building. You would want to attach a commandlistener to that command (I don't know the name, if it even exists) and return Plugin_Handled in that callback.

As Potato Uno said, you can't block events as they are just notifications.

The command for dropping a building is "build" so you can try to use AddCommandListener and return Plugin_Handled.

Sorry, I should have included the code where I hook the event. I am using EventHookMode_Pre as my third parameter.

I'm going off this page from the sourcemod wiki. Are these instructions wrong, or is it just for player_builtobject that it doesn't work?

Just tried this tonight, and it worked for blocking "build". But I'm hoping to block the build command for one particular building, not for all of them. Any suggestions on how to do that?

Inside the command callback, use GetCmdArg. There are two arguments for the build command. First is the building type, second is the building mode. The values for each can be found in tf2.inc.
