Re: [L4D1] Door-less elevator at No Mercy [APRIL/2020]
 
I tried many ways to create an explosion on doors but nothing worked.
My idea was creating a propane tank on doors, make it invisible and make it explode, but it didn't work because propane tank got in flames but it never explodes. Even if I shoot at it, it doesn't explode. I have to pick it up and drop it to make it vulnerable to bullets.

Look at other plugins for examples. "expode" from "env_explosion" in Mutants (bomb type), or Flare Gun, or Pourgas, or Airstrike plugin. They all demonstrate one method. Another for replicating Propane tank would be using "prop_physics" and "break" input, see Greandes or Pourgas which does this using the firework /gascan models, just change to use propane model and you should have the same effect.

It was very helpful. "prop_physics" is what I was looking for, thanks. Explosion is now working. I will update it soon

The code is very non-optimized.

I would suggest to hook "player_use" only when map is "l4d_hospital04_interior" instead of checking it constantly.
You can use OnMapStart forward to do that.

Anyway, "player_use" is also fire too often. It's inefficient to make the check everytime.
Instead you could just hook exactly that entity. If you decide to follow this way, some entities could not initialize yet at map start stage so "round_freeze_end" is preferrable.

PHP Code:
public void OnPluginStart()
{
    HookEvent("round_freeze_end",         Event_RoundFreezeEnd,    EventHookMode_PostNoCopy);
}

public void Event_RoundFreezeEnd(Event event, const char[] name, bool dontBroadcast)
{
    static char sMap[32], sName[64];
    int entity = -1;
    
    GetCurrentMap(sMap, sizeof(sMap));
    
    if (strcmp(sMap, "l4d_hospital04_interior") == 0)
    {
        while (-1 != (entity = FindEntityByClassname(entity, "func_button")))
        {
            GetEntPropString(entity, Prop_Data, "m_iName", sName, sizeof(sName));
            if (strcmp(sName, "elevator_button") == 0)
            {
                HookSingleEntityOutput(entity, "OnPressed", OnButtonAction, true);
                break;
            }
        }
    }
}

void OnButtonAction(const char[] output, int caller, int activator, float delay)
{
    // some code
}

Hello, your optimization is very helpful. I wrote this code like this only for testing. My plan for initial release was adding a timer on OnMapStart() and check once for mapname, but round_freeze_end is better, I completely forgot about that event.
I will consider this for first stable version.
