# Raw Content Manager
|
|
|
|
Sometimes, there's a good reason for wanting to load game assets directly rather than using the MonoGame Content Pipeline, which packs files into a binary `xnb` format. Those reasons include, for example, making your game easily moddable or allowing for texture packs.
|
|
|
|
The **MLEM** package contains a solution for this: `RawContentManager`.
|
|
|
|
## What it does
|
|
A raw content manager works very similarly to a regular `ContentManager`: You can load different types of assets through the `Load<T>` method, and they will automatically be managed and disposed when the game closes.
|
|
|
|
However, the `RawContentManager` loads assets in their usual file type, rather than `xnb`, meaning that they don't have to be compiled using the Content Pipeline first.
|
|
|
|
## How to use it
|
|
To create a new raw content manager, simply call its constructor in your `LoadContent` method. Optionally, you can add it as a game component, which will automatically dispose it when the game closes.
|
|
```cs
|
|
protected override void LoadContent() {
|
|
this.rawContent = new RawContentManager(this.Services);
|
|
this.Components.Add(this.rawContent);
|
|
|
|
// load other content here
|
|
}
|
|
```
|
|
|
|
Then, you can simply load an asset in your `Content` directory like you would with the regular `ContentManager`:
|
|
```cs
|
|
this.testTexture = this.rawContent.Load<Texture2D>("Textures/Test");
|
|
```
|
|
|
|
## Adding more content types
|
|
By default, the raw content manager supports the following types, as long as their files are appended with one of the supported file extensions:
|
|
- `Texture2D` (png, bmp, gif, jpg, tif, dds)
|
|
- `SoundEffect` (ogg, wav, mp3)
|
|
- `Song` (gg, wav, mp3)
|
|
- Any XML files (xml)
|
|
- Any JSON files (json) if `MLEM.Data` is used
|
|
|
|
To add more content types that can be loaded by the raw content manager, you simply have to extend either `RawContentReader` or the generic version, `RawContentReader<T>`. For example, this is a content reader that loads a `txt` file as a string:
|
|
```cs
|
|
using System.IO;
|
|
using MLEM.Content;
|
|
|
|
namespace Test {
|
|
public class StringReader : RawContentReader<string> {
|
|
|
|
public override string[] GetFileExtensions() {
|
|
// return an array of supported file extensions
|
|
return new[] {"txt"};
|
|
}
|
|
|
|
protected override string Read(RawContentManager manager, string assetPath, Stream stream, string existing) {
|
|
// use the stream (or the asset path) here and
|
|
// return the loaded content file
|
|
using (var reader = new StreamReader(stream))
|
|
return reader.ReadToEnd();
|
|
}
|
|
|
|
}
|
|
}
|
|
```
|
|
As `RawContentManager` automatically collects all raw content readers in the loaded assemblies, you don't have to register your custom reader anywhere. |
