Wallhack effect (No depth)

[zero_tolerance]

By RoverTurbo

Drawing objects with the z-buffer (depth) disabled will make objects appear visable even when hidden behind other objects.

HRESULT APIENTRY IDirect3DDevice9::DrawIndexedPrimitive(D3DPRIMITIVETYPE Type, INT BaseVertexIndex, UINT MinIndex, UINT NumVertices, UINT startIndex, UINT PrimitiveCount)
{

  Device->SetRenderState(D3DRS_ZENABLE, false);

  Device->DrawIndexedPrimitive(Type, BaseVertexIndex, MinVertexIndex, NumVertices, startIndex, primCount);

  Device->SetRenderState(D3DRS_ZENABLE, true);

  return Device->DrawIndexedPrimitive(Type, BaseVertexIndex, MinVertexIndex, NumVertices, startIndex, primCount);

}

Adding some model recognition will allow you to apply the effect to single objects.
