public Action OnDoorClose(Event event, const char[] name, bool dontBroadcast)
{
    bool isCheckpoint = event.GetBool("checkpoint");

    }
    
    // do stuff here

Almost accurate but with a minor setback, the bool applies to both kinds of saferoom doors.

Or player_use event:

PHP Code:

bool alreadyDone;

HookEvent("round_start", OnRoundStart);
HookEvent("player_use", OnPlayerUse, EventHookMode_Pre);

public Action OnRoundStart(Event event, const char[] name, bool dontBroadcast)
{
    if (!alreadyDone) // prevent bug
    {
        return Plugin_Continue;
    }
    
    alreadyDone = false;
    return Plugin_Continue;
}

public Action OnPlayerUse(Event event, const char[] name, bool dontBroadcast)
{
    if (alreadyDone) // in order to prevent spam
    {
        return Plugin_Continue;
    }
    
    int usedTarget = event.GetInt("targetid");
    if (usedTarget == -1 || !IsValidEntity(usedTarget) || !IsValidEdict(usedTarget))
    {
        return Plugin_Continue;
    }
    
    char targetModel[PLATFORM_MAX_PATH], targetEnt[64];
    
    GetEntPropString(usedTarget, Prop_Data, "m_ModelName", targetModel, sizeof(targetModel));
    GetEntityClassname(usedTarget, targetEnt, sizeof(targetEnt));
    
    if (StrContains(targetModel, "checkpoint_door", false) != -1 && StrEqual(targetEnt, "prop_door_rotating_checkpoint", false)) // make sure the model is a checkpoint door and it is a checkpoint entity 'cause some maps have these models but are not real checkpoints and more like props.
    {
        alreadyDone = true;
        
        if (targetModel[36] == '1' || targetModel[37] == '1') // 'cause some maps use saferoom models with a negative sign before 0.
        {
            // do stuff here
        }
        else if (targetModel[36] == '2' || targetModel[37] == '2') // same with the end saferoom.
        {
            // do stuff here
        }
    }
    
    return Plugin_Continue;
} 


By far is much better as this event checks it all - the model, the entity classname, etc. I would recommend this even advise myself when making plugins involving entities.
