I have a plugin I am working on that makes use of the 'TR_TraceRayFilter' feature. I have it setup to poll every player every 0.5 seconds using OnGameFrame(). I am having some crash issues since I started using it, only when the server starts to get busy it happens. I have even looked at the crash dump (Linux OS), and the only hint I can get about the issue is a line:

IVP_OO_Watcher::hull_limit_exceeded_event()

The code below are the only two events I am using with the 'TR_' based functions, I want to make sure I am calling them right. The plugin works correctly but something is certainly amiss, I just want to make sure I have the trace portion setup right so I can debug the rest. Do I need to use a TR_TraceRayFilterEx instead with a handle/close handle? I am not sure if it is possible to get too many Traces going at once leading to an eventual crash. Any input is greatly appreciated.

PHP Code:

stock float GetEyeDistance(int client, int MASK_TYPE) {
    if(IsClientValid(client)) {
        float fEyeAngles[3], fTraceStart[3], fTraceEnd[3];

        GetClientEyeAngles(client, fEyeAngles);

        GetClientEyePosition(client, fTraceStart);

        TR_TraceRayFilter(fTraceStart, fEyeAngles, MASK_TYPE, RayType_Infinite, TRDontHitClients, client);  

        TR_GetEndPosition(fTraceEnd);
        if(TR_DidHit(INVALID_HANDLE))
        { return GetVectorDistance(fTraceStart, fTraceEnd); }
    }

    return 0.0;
}


stock int GetEntityAtCrosshair(int client) {
    float fStart[3], fEnd[3], Ang[3];

    GetClientEyePosition(client, fStart);
    GetClientEyeAngles(client, Ang);
    TR_TraceRayFilter(fStart, Ang, MASK_SHOT, RayType_Infinite, TraceRayDontHitSelf, client);

    if(TR_DidHit(INVALID_HANDLE)) { TR_GetEndPosition(fEnd, INVALID_HANDLE); }
    return TR_GetEntityIndex();    
}


public bool TraceRayDontHitSelf(int entity, int mask, any data) 
{ return (entity != data); }


stock bool TRDontHitClients(int entity, int mask, any data) {
    if (!IsClientValid(entity)) { return true; }
    return false;
}


stock bool IsClientValid(int client)
{ return (1 <= client <= MaxClients && IsClientInGame(client)); }

Is there any limitation to the TR_TraceRayFilter and/or TR_TraceRayFilterEx functions? Is it possible to have too many traces at once or before a map change causing an overflow or something (similar to how an edict overflow crash)? As I said before I have had zero issues until the server starts filling up with more players and then the crash happens. Very odd, hope someone can shine some light on this. Thanks in advance.

As far as I understand a trace happens in real time.

Meaning TR_TraceRayFilter starts the trace and calls all the filter callbacks and by the time it's done and returns the trace is complete.

With this being said I dont think it's possible to even have two traces running at once.

Thanks for the reply and info Neuro. What if two separate plugins fired a trace at the same time? I wonder if that would cause issues, I do have another plugin that fires traces. All speculation of course, but it is definitely a weird crash. I am still not sure what is causing it.

As SM runs on a single thread it's impossible for two traces to run at once.

I suggest you install accelerator to help with debugging the crash.

Thank you for clarifying, I appreciate it. I might have a look at accelerator; are there any sample outputs from it somewhere to see if this is something I want to use?

If you're on CS:GO it might give less friendly output, but post it here anyway and some gurus may possibly be able to help you diagnose the issue.

You want to get the entity ID. And if there is no Entity at the end point?
