Cannot transform the design to my own

[willing1234]

I tried several time, but it is not works. After import and export a design code, it suppose to be edit on you switch, but no matter what I do, it is not working, However, my friend create a file for me, and import the code I upload in community, it is works. Do anyone know what's the problem?

I answered this issue in #30. Will continue commenting there.

Issue #30 was closed by opener, so continuing conversation here (years later).

Issue #27 & #30 are related.

The ACNH file format needs to include the players PlayerID and TownID from main.dat or personal.dat being written to the pattern data and then written back to main.dat at each pattern index.

ACNHDesignPatternEditor/Assets/Plugins/ACNHFileFormat.cs

Lines 97 to 107 in 498aa02

	public ACNHFileFormat(byte[] bytes)
	{
	Version = bytes[0];
	Name = System.Text.Encoding.Unicode.GetString(bytes, 1, 0x29).Replace(" ", "").Trim();
	Palette = new DesignPattern.Color[15];
	this.Type = (DesignPattern.TypeEnum) bytes[0x2B];
	for (int i = 0; i < 15; i++)
	Palette[i] = new DesignPattern.Color() { R = bytes[0x2C + i * 3 + 0], G = bytes[0x2C + i * 3 + 1], B = bytes[0x2C + i * 3 + 2] };
	this.Pixels = new byte[Width / 2 * Height];
	Array.Copy(bytes, 0x59, this.Pixels, 0, this.Pixels.Length);
	}

Similarly to the way that the ACNL file format reads/writes those bytes:

ACNHDesignPatternEditor/Assets/Plugins/ACNLFileFormat.cs

Lines 457 to 458 in 498aa02

	Username = System.Text.Encoding.Unicode.GetString(bytes, 0x2c, 20).Replace(" ", "").Trim();
	TownName = System.Text.Encoding.Unicode.GetString(bytes, 0x42, 20).Replace(" ", "").Trim();

But read from the *.dats and written to the pattern byte arrays would be best (not relying on pattern dumps that originate from the user).

Without those IDs written to the start of each pattern array the game marks them as not owned by the player and thus unable to be edited within the game (marked with 🚫).

Refer here for details on the data side.

If I get time I might look over the codebase and implement, but it might be quicker for @FluffyFishGames to action it due to familiarity with the codebase.

I would also recommend not using a trimmed file format for the pattern exports to increase interoperability.
