Reply To: DX 11 implementation

Well, in blitzmax you simply do SetBlend LightBlend. But looking into the directx module that handles it all for you the setblend function looks like this: (bear in mind that this is DX9)

	Method SetBlend( blend )
		If blend=_active_blend Return
		Select blend
		Case SOLIDBLEND
			_d3dDev.SetRenderState D3DRS_ALPHATESTENABLE,False
			_d3dDev.SetRenderState D3DRS_ALPHABLENDENABLE,False
		Case MASKBLEND
			_d3dDev.SetRenderState D3DRS_ALPHATESTENABLE,True
			_d3dDev.SetRenderState D3DRS_ALPHABLENDENABLE,False
		Case ALPHABLEND
			_d3dDev.SetRenderState D3DRS_ALPHATESTENABLE,False
			_d3dDev.SetRenderState D3DRS_ALPHABLENDENABLE,True
			_d3dDev.SetRenderState D3DRS_SRCBLEND,D3DBLEND_SRCALPHA
			_d3dDev.SetRenderState D3DRS_DESTBLEND,D3DBLEND_INVSRCALPHA
		Case LIGHTBLEND
			_d3dDev.SetRenderState D3DRS_ALPHATESTENABLE,False
			_d3dDev.SetRenderState D3DRS_ALPHABLENDENABLE,True
			_d3dDev.SetRenderState D3DRS_SRCBLEND,D3DBLEND_SRCALPHA
			_d3dDev.SetRenderState D3DRS_DESTBLEND,D3DBLEND_ONE
		Case SHADEBLEND		
			_d3dDev.SetRenderState D3DRS_ALPHATESTENABLE,False
			_d3dDev.SetRenderState D3DRS_ALPHABLENDENABLE,True
			_d3dDev.SetRenderState D3DRS_SRCBLEND,D3DBLEND_ZERO
			_d3dDev.SetRenderState D3DRS_DESTBLEND,D3DBLEND_SRCCOLOR
		End Select
		_active_blend=blend
	End Method
