MonoGame.Reload is an hot-reloader for your MonoGame application.
No more thousands of restarts of your game to try out a new version of your assets.
Set up the hot-reloader in a flash and simply enjoy the magic.
Installation
MonoGame.Reload is available as a NuGeT package here.
The way to initialize the library has been reworked and simplified.
You now have helper to quickly render textures, models, aseprite files or play sounds and songs
0.2.0 updates
Since MonoGame.Reload v0.2.0, the library can reload Aseprite files using MonoGame.Aseprite written by Aristurtle. Check it out for more informations!
New assets are now supported :
Aseprite files
Data files (.txt, .json, .xml, ...)
You can now attach a callback to a file by listening the Updated event. The callback will be invoked right after the file has been reloaded.
Disclaimer
Things you have to know is the library watch updates of your content directory files. But when you are using Visual Studio to update a specific file (for example, double-clicking on an Effect file will open it inside Visual Studio), and when you are modiying then saving the file, Visual Studio create a temporary file which creating issues with the library.
I don't know if I can improve the library to avoid this behavior, even using Visual Studio, but at this time, you should avoid it and use Visual Studio Code for example which is the code editor I tested during the library development
Getting started
Firstly, initialize the reloader inside the Initialize function:
In some cases, you don't need to watch some files extensions. You can do so by using a simple function:
protected override void Initialize()
{
// Right after the Reloader.Initialize(...)
Reloader.Ignore(AssetType.Model, AssetType.Song);
}
You can put on the Ignore function as many AssetType as you want and all these types will be ignored if they are listened by the Reloader.
Access a single file
Sometimes, you'll need to retrieve a single asset. Depending on the type of the asset, you will have access to it inside the AssetsManager class.
// Access to a Texture2D
AssetsManager.Textures["path/name_of_my_texture"];
Note: You have to respect the hierarchy of your files.
In the example above, the file "name_of_my_texture" is contained inside the folder Sprites inside the Content directory.
2nd Note: If the key of the texture does not exists, an exception will be thrown, so you may want to check if the texture name exists by using Textures2D.ContainsKey(string key).
Listen a file update
You can attach a callback to a file for it to be invoked when the file is updated:
protected override void LoadContent()
{
// ...
// Make sure you already load your files
Reloader.OnUpdate("path/asset_name", (object sender, FileSystemEventArgs args) => {
Console.WriteLine("The path/asset_name file has been updated");
});
}
Assets usage
If you want draw a texture or an Aseprite sprite, you can use a shortcut of the library which will render the asset if the asset is available:
Note that these function are basic and do not use all the features you should want to use.
In that case, you can access the asset via the dictionaries as I mentioned them in the Access a single file section.
Roadmap
I'm always looking to improve this library.
