mike: I would recommend the forums on creators.xna.com for this question. Blog post comments aren't really the best place for posting code snippets etc!

In xna 3.1, is it possible to set the processor parameters in code. The context is if i was use msBuild to build content, it seems like i'm stuck using the default values for the model processor.

Looks like I answered my own question again.

You need to do: [DefaultValue(typeof(Color), "0, 255, 0, 255")]

OK, it looks like you have to type the Color into the text box in the format: R,B,G,A

Then after you compile the nested R,B,G,A props become available.

I take it the "[DefaultValue(Color.Magenta)]" entry won't work though?

Hi Shawn,

I have the following code in a Custom Texture Processor class:

private Color colorKeyColor = Color.White;

[DisplayName("Color Key Color")]

//[DefaultValue(Color.Magenta)]

[Description("Color Key")]

public Color ColorKeyColor

{

get { return colorKeyColor; }

set { colorKeyColor = value; }

}

The problem is that the ColorKeyColor prop only shows up as a textbox in the Property Grid, how to I get it to have nested R,G,B,A properties like the standard Texture Processor?

Also If I uncomment the "[DefaultValue(Color.Magenta)]" line I get an error. How can I set the default Color for this property in the PropertyGrid?

Thanks!!

Just a heads up for anyone new to C# trying to use this information. You need to also include the following line to your list of assemblies if you wish to support the [DefaultValue()], [DisplayName()] and [Description()] method attributes.

using System.ComponentModel;

sorry to sound newbish but I was just wondering how you create a public property. I see the option to add a new content processor. Any direction in this subject would be greatly appreciated.

On another note that's awesome that we can change these attributes so easy :)

I'm not sure how the PropertyGrid control would handle this, but if it's "gracefully", why not merge Color Key Color and Color Key Enabled to just be a nullable Color Key?

From the pictures above, by setting "Generate tangent frames" to "true", the processor then (re)generates the normal, tangent and binormal vectors for the model, or is it something different?
