Hi,

so been trying to get into SM extensions so far everything i made worked. Now i wanted to create a simple GetWeaponShootPosition native which takes a client and returns a float array. I got that setup but it seems im doing something wrong because it crashes right away. Looking through the source sdk 2013 code the function Weapon_ShootPosition seem to return a vector. So im not sure how i would handle the vector correctly as pointer or normal variable because the function itself doesn't return a vector pointer.

PHP Code:

cell_t Native_GetWeaponShootPosition(IPluginContext *pContext, const cell_t *params)
{
    static ICallWrapper *pWrapper = NULL;
    if(!pWrapper)
    {
        REGISTER_NATIVE_ADDR("CBasePlayer::Weapon_ShootPosition",
            PassInfo pass[1]; \
            PassInfo ret;\
            pass[0].flags = PASSFLAG_BYVAL; \
            pass[0].size = sizeof(CBaseEntity *); \
            pass[0].type = PassType_Basic; \
            
            ret.flags = PASSFLAG_BYVAL;\
            ret.size = sizeof(Vector);\
            ret.type = PassType_Basic;\
            pWrapper = g_pBinTools->CreateCall(addr, CallConv_ThisCall, &ret, pass, 1));
    }
    CBaseEntity *pEntity;
    if(!(pEntity = GetCBaseEntity(params[1], true)))
    {
        return pContext->ThrowNativeError("Client index %d is invalid",params[1]);
    }
    
    cell_t *pPos;
    pContext->LocalToPhysAddr(params[2], &pPos);
    
    unsigned char vstk[sizeof(CBaseEntity *)];
    unsigned char *vptr = vstk;
    
    *(CBaseEntity **)vptr = pEntity;
    vptr +=sizeof(CBaseEntity *);
    Vector pos;
    pWrapper->Execute(vstk, &pos);
    
    pPos[0] = sp_ftoc(pos.x);
    pPos[1] = sp_ftoc(pos.y);
    pPos[2] = sp_ftoc(pos.z);
    return 1;
}
