Tut: copy pasta fixed weapon backright without game crash - 3rd attm

[IKaruzI15]

Hey guys Im IKaruzI and the coder of zmmo,

Now the time came that I have to do some easy tutorials, because iss is 100% dead from now!

copy pasta should work, this will display the gun as first person model on your back, without game crash.

void CUberEquip::Draw(const r3dSkeleton* skel, const D3DXMATRIX& CharMat, bool draw_weapon, DrawType dt, bool first_person)
{
    //todo: call extern void r3dMeshSetWorldMatrix(const D3DXMATRIX& world)
    // instead of mesh->SetWorldMatrix

    // in first person mode we need to render player and gun into different Z range
    if(dt == DT_AURA)
    {
        float expandConst[ 4 ] = { r_aura_extrude->GetFloat(), 0.f, 0.f, 0.f } ;
        D3D_V(r3dRenderer->pd3ddev->SetVertexShaderConstantF(23, expandConst, 1)) ;
    }

    skel->SetShaderConstants();

    for(int i=0; i<=SLOT_Backpack; i++) //Disable BackPack, This logic will cause the player who uses the backpack ID 999333 to become invisible
    {
         if((d_disable_backpacks_draw->GetBool() /*g_RenderBackpack->GetInt() == 1*/ || player->CurLoadout.BackpackID >= 20260 && player->CurLoadout.BackpackID <= 20264) && i == SLOT_Backpack)
             continue;

        DrawSlot((ESlot)i, CharMat, dt, true, first_person, NULL);
    }


    if(dt != DT_AURA)
    {
        D3DXMATRIX world = getWeaponBone(skel, CharMat);
        if(!first_person)
        {
            if(slots_[SLOT_WeaponBackRight].wpn) // tobi 1
            {
                world = getWeaponBone(skel, CharMat);
                bool skinned = false;
                r3dSkeleton* wpnSkel = game_new r3dSkeleton(); // so traurig fixt waffe aufm rücken und crasht nichtmal....
                Weapon* wpn = slots_[SLOT_WeaponBackRight].wpn;

                wpn->checkForSkeleton(); // so traurig fixt waffe aufm rücken und crasht nichtmal.... und dann nocheinmal checken lassen und gut ist.
                //game_new r3dAnimation();

                //wpn->m_pConfig->m_AnimPool_FPS = game_new r3dAnimPool();
                //wpn->m_WeaponAnim_FPS = game_new r3dAnimation();

                //if(wpn->getAnimation()->bInited == 0)
                //    wpn->getAnimation()->bInited = 1;

                if(wpn)
                {
                    r3dMesh* msh = wpn->getModel(true, first_person);
