Where are the basic color values coded?

[Drachenbauer]

Hello

Is there any way to change the 16 basic color values (for banners, shields, sheep-wool, wolf-collars, ...) with a mod?

 

Where in minecraft´s code are they stored?

[diesieben07]

Check the TextFormatting enum.

[Drachenbauer]

theese are textcolors, not the colors, i mean.

I found out, that, what i mean, is in DyeColor.

 

What is the best way to get my own colorvalues in there?

Most things that use the colors (excluding leather armor and such) don't use them dynamically; you'd have to actually change the textures, names, etc. to have any effect.

In any case, no. There's no reasonable way to change anything to do with DyeColor. Oh right, reflection duh.

I'm dumb

[Drachenbauer]

I really want to change the colorvalues for the things, i listed in the startpost.

The other stuff, with textures, is already done.

 

There must be a solution.

Optifine did it, too.

DyeColor is also an enum which stores various colors in fields. You can probably change them.

[Drachenbauer]

I´m not sure, how.

if i any where create own DyeColor-values, how can i apply them to the things in the game, wich use this enum?

There are fields in the DyeColor class which hold the colors. Change them using reflection.

[Drachenbauer]

Must i extend and override all classes, that uses Dyecolor to do this?

I saw some of them diectly using the prepared Colors on top of the enum

What do you mean by this? Provide more details.

[Drachenbauer]

The sheep has this:

 

public static DyeColor getRandomSheepColor(Random random)
    {
        int i = random.nextInt(100);
        
        if (i < 5)
        {
            return DyeColor.BLACK;
        }
        else if (i < 10)
        {
            return DyeColor.GRAY;
        }
        else if (i < 15)
        {
            return DyeColor.LIGHT_GRAY;
        }
        else if (i < 18)
        {
            return DyeColor.BROWN;
        }
        else if (random.nextInt(500) == 0)
        {
            return DyeColor.PINK;
        }
        else
        {
            return DyeColor.WHITE;
        }
    }

So...?

[Drachenbauer]

how can i make it use custom values?

I already told you like, three times. Have you looked at the DyeColor class at all?

[Drachenbauer]

Yes.

I know about theese fields.

Must i extend and override the sheep to replace the stuff, shown above, with such custom colorvalues?

I don´t know, how to put stuff with custom values in theese fields, behind the "return" in this mthod there?

Edited April 11, 2020 by Drachenbauer

[diesieben07]

Please learn basic Java.

[Drachenbauer]

This method want´s to return an object of the type Dyecolor.

And i noticed, that i cannot make a custom instance of it, because this is not possible with an enum.

Why don´t you just tell me, how to use the int field colorValue, where it wants to return DyeColor?

[diesieben07]

Jesus lord have mercy.

DyeColor has instance fields that store the color values.

Change them using reflection.

Do not create new DyeColor instances, do not try to modify the code that uses DyeColor, do not pass go, do not collect $400.

[Drachenbauer]

At searching for "change fields with reflection" i found this:

        Class<?> clazz = Class.forName("Child");
        Object cc = clazz.newInstance();

        Field f1 = cc.getClass().getField("a_field");
        f1.set(cc, "reflecting on life");

 

But if i try to use DyeColors in there, it says things about IllegalAcessExeption.

i hat to put theese exeptionhandlings to the header of the function, i placed this in.

 

another question:

A color-field holds alot of content;

WHITE(0, "white", 16777215, MaterialColor.SNOW, 16777215, 16777215),

how do i put all this into the setter of this reflection-stuff?

Edited April 11, 2020 by Drachenbauer

1. You have to use ObfuscationReflectionHelper with SRG names when reflecting fields from vanilla Minecraft, otherwise your code will not work outside the development enviornment.
2. If you want to access private fields using reflection, you have to use setAccessible(true). ObfuscationReflecitonHelper already does this for you.

   Look at the DyeColor constructor and how it stores these parameters into fields. The fields are what you want to override. Please learn basic Java.

[Drachenbauer]

I cannot find codesamples, where someone uses ObfuscationReflectionHelper to override fields in an enum.

I really must see working code for this, to find out, how exactly it must look like.

 

i never ured reflection before.

Setting field values in an enum is not any different than with any other class.

[Drachenbauer]

        ObfuscationReflectionHelper.setPrivateValue(DyeColor.class, DyeColor.WHITE, 16777215, "colorvalue");
        ObfuscationReflectionHelper.setPrivateValue(DyeColor.class, DyeColor.WHITE, 16777215, "fireworkColor");
        ObfuscationReflectionHelper.setPrivateValue(DyeColor.class, DyeColor.WHITE, 16777215, "textColor");

Is this the way to do it?

 

To repeat for all 16 colors.

Edited April 11, 2020 by Drachenbauer

[diesieben07]

Yes, except please use hex literals for colors and you must use SRG names, like I said.

[Drachenbauer]

how do i find the SRG-names?

And do you mean only for the variabls, or for class and instance, too?
