[module] Unsure how to properly use ChangeDirectory()

So, I’m using Raylib-CS on macos, so that might be pertinent. Right now, for loading assets I am using a solution I picked up from using Monogame. It goes something like this: Check “copy to output directory” on all assets (images etc). Then I use this function whenever I’m loading a file:

static string getFullPath(string relativePath)
{
	string baseDirectory = AppDomain.CurrentDomain.BaseDirectory;
	return System.IO.Path.Combine(baseDirectory, relativePath);
}

Font ALAGARD = LoadFont(getFullPath("Assets/fonts/alagard.png"));
Image cursorImage = LoadImage(getFullPath("Assets/cursor.png"));

This works for me, but I’ve been made aware that another solution would be to call ChangeDirectory(GetApplicationDirectory());

The issue is, I don’t know how to use this function properly with C#. I get the following errors:

Again, what I was already doing works, but I’m curious how to use these functions properly. It doesn’t seem like using “unsafe” should be required. I feel that I am missing something obvious here, any help would be appreciated!

@differenceclouds Oh, the ref keyword is common in C#: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/ref

When you use void ImageRotateCW(ref Image image) for example, the with and height of the image change and in order to update the fields, you have to provide a reference.

That’s because Image is a struct and not a class.

Have a look at Utf8StringUtils it allows you to convert pointers to strings and back.

As for the current directory, try and prefer the built-in C# methods, e.g. System.Numerics over RayMath, AppDomain.CurrentDomain.BaseDirectory or Assembly.GetExecutingAssembly().Location over raylib.GetApplicationDirectory, etc.
