Use XNA like DirectX9, Transparencies

Hi,

I have been trying to achieve alpha blending in XNA. I don't want to use the Spritebatch class. I have tried playing around with the renderstate and setting a colour key.

Code to create Colourkey:

Code:

---

            TextureCreationParameters tt = new TextureCreationParameters();
            tt = TextureCreationParameters.Default;
            tt.ColorKey = new Color(0, 0, 0);
            tt.Format = SurfaceFormat.Rgba32;

            inSheet.texData = Texture2D.FromFile(device, assetName, tt);

---

Code setting renderstate:

Code:

---


            device.RenderState.AlphaSourceBlend = Blend.SourceAlpha;
            device.RenderState.AlphaDestinationBlend = Blend.InverseSourceAlpha;
            device.RenderState.AlphaBlendEnable = true;

---

Have I gone mad and tried to use XNA like DX9? :confused:

Or is there a way?

Find my whole project attached.

ah, Fixed, it turns out all I had to do was change:

Code:

---

      device.RenderState.AlphaSourceBlend = Blend.SourceAlpha;
            device.RenderState.AlphaDestinationBlend = Blend.InverseSourceAlpha;
            device.RenderState.AlphaBlendEnable = true;

---

into:

Code:

---


      device.RenderState.SourceBlend = Blend.SourceAlpha;
            device.RenderState.DestinationBlend = Blend.InverseSourceAlpha;
            device.RenderState.AlphaBlendEnable = true;

---

I was blending the alpha values and not the colours :blush:
