Edit The JsonContentTypeWriter

On the previous page we discussed the anatomy of a ContentTypeWriter. Now that we have an understanding of this, let's make the changes necessary to our JsonContentTypeWriter class so that it writes the results to an .xnb file.

Open the JsonContentTypeWriter.cs file and make the following adjustments:

using Microsoft.Xna.Framework.Content.Pipeline;
using Microsoft.Xna.Framework.Content.Pipeline.Serialization.Compiler;

using TInput = JsonContentPipelineExtension.JsonContentResult;

namespace JsonContentPipelineExtension
{
    [ContentTypeWriter]
    internal class JsonContentTypeWriter : ContentTypeWriter<TInput>
    {
        protected override void Write(ContentWriter output, TInput value)
        {
            output.Write(value.Json);
        }

        public override string GetRuntimeReader(TargetPlatform targetPlatform)
        {
            return "JsonContentPipeline.JsonContentReader, JsonContentPipeline";
        }
    }
}

For the purposes of the example being used in this tutorial, there was not much we needed to adjust here.

1. The TInput using alias was changed to our JsonContentResult type.
2. We updated the logic of the Write(ContentWriter, TInput) method to write out JSON string to the .xnb file.

Note, however, the value that we are returning for the GetRuntimeReader(TargetPlatform) method. The fully-qualified type path uses an assembly name that is different than our JsonContentPipelineExtension assembly. This is because we're going to place the reader in a separate project, which will be explained in the upcoming sections.

Next Steps

That is it for our JSON writer. It simply just takes in the data given from the JsonContentProcessor and writes the single JSON string to the .xnb file.

On the next page, we'll go over creating a new MonoGame Game Library project that we'll put our JsonContentTypeReader into and go over the reasons why we do this.
