[Question] TraceRay crashing the game topic

Seems like i can't get this to work. Since almost everyone out there probably has that one working, does someone see what could possibly be wrong in here?

I'm using engine.dll and EngineTraceClient0 to obtain the pointer to IEngineTrace, that should be fine. (ptr is not null)

Code:

---

struct cplane_t
{
        Vector  normal;
        float  dist;
        BYTE    type;
        BYTE    signbits;
        BYTE    pad[2];
};

class CBaseTrace
{
public:
        Vector                  startpos;
        Vector                  endpos;
        cplane_t                plane;
        float                  fraction;
        int                            contents;
        unsigned short  dispFlags;
        bool                    allsolid;
        bool                    startsolid;
};

struct csurface_t
{
        const char*            name;
        short                  surfaceProps;
        unsigned short  flags;
};

class CGameTrace : public CBaseTrace
{
public:
        bool                    DidHitWorld() const;
        bool                    DidHitNonWorldEntity() const;
        int                            GetEntityIndex() const;
        bool                    DidHit() const;
public:
        float                  fractionleftsolid;
        csurface_t              surface;
        int                            hitgroup;
        short                  physicsbone;
        unsigned short  worldSurfaceIndex;
        CBaseEntity*              m_pEnt;
        int                            hitbox;
};

inline bool CGameTrace::DidHit() const
{
        return fraction < 1.0f || allsolid || startsolid;
}

typedef CGameTrace trace_t;

enum TraceType_t
{
        TRACE_EVERYTHING = 0,
        TRACE_WORLD_ONLY,
        TRACE_ENTITIES_ONLY,
        TRACE_EVERYTHING_FILTER_PROPS,
};

class ITraceFilter
{
public:
        virtual bool            ShouldHitEntity(PVOID pEntity, int contentsMask) = 0;
        virtual TraceType_t    GetTraceType() const = 0;
};

---

Code:

---

                void TraceRay(const Ray_t &ray, unsigned int fMask, ITraceFilter* pTraceFilter, trace_t* pTrace)
                {
                        typedef void(__thiscall* fnTraceRay)(void*, const Ray_t&, unsigned int, ITraceFilter*, trace_t*);
                        ToVirtual<fnTraceRay>(this, 5)(this, ray, fMask, pTraceFilter, pTrace);
                }

---

Code:

---

                        source_engine::Ray_t ray;
                        source_engine::trace_t trace;

                        ray.Init(pLocalPlayer->GetEyePos(), pBasePlayer->GetEyePos());
                        pEngineTrace->TraceRay(ray, 0x4600400B, NULL, &trace); //crashs here

Thanks in advance.
