Java

In your Java file containing all your blocks (create one if you don't already have one) imports the MultiCrater library.

import multicraft.*

Then create a new block with the type MultiCrafter

Block mine-crafter = new MultiCrafter("mine-crafter") {{

}};

You can add recipes like this:

resolvedRecipes = Seq.with(
    new Recipe() {{
        input = new IOEntry() {{
            items = ItemStack.with(
                Items.copper, 1,
                Items.lead, 1
            );
        }};
        output = new IOEntry() {{
            items = ItemStack.with(
                Items.surgeAlloy, 1,
                Items.thorium, 1
            );
        }};
        craftTime = 120f;
    }},
    new Recipe() {{
        input = new IOEntry() {{
            items = ItemStack.with(
                Items.copper, 1
            );
        }};
        output = new IOEntry() {{
            items = ItemStack.with(
                Items.copper, 1,
                Items.beryllium, 1
            );
        }};
        craftTime = 160f;
    }}
);

Recipe

A recipe has several fields:

Field	Type	Note
input	IOEntry
output	IOEntry
crafterTime	Float	how long to do a synthesis, can be 0.
icon	Prov<TextureRegion>	such as Icon.lock-open. See Icon
iconColor	Color (RGB, RGBA, rgba8888 or Hex)	a color for icon

Input and Output

The input or output are IOEntry. With this style, its power is unlimited.

Key	Type	Note
items	ItemStack[]	how much item for input/output, default: empty
fluids	LiquidStack[]	how much fluid for input/output, default: empty
power	Float | unit: power/tick	how much power for input/output, default: 0f
heat	Float	how much heat for input/output, default: 0f
icon	Icon	such as Icon.lock-open. See Icon
iconColor	Color (RGB, RGBA, rgba8888 or Hex)	a color for icon
craftEffect	Effect	an independent craft effect for each recipe

Icon

You can customize which icon is used for your recipe selector menu.

If you don't set a dedicated icon, it will find the first one from the recipe.

For example:

alphaaaamono

icon = Icon.alphaaaa
iconColor: F30000

switchStyle = RecipeSwitchStyle.simple;
resolvedRecipes = Seq.with(
    new Recipe() {{
        input = new IOEntry(){{
            fluids = Seq.with(
                Liquids.ozone, 1.5f
            );
        }};
        output = new IOEntry() {{
            items = Seq.with(
                Items.coal, 1
            )
            power = 2f;
            icon: alphaaaa
            iconColor = Color.valueOf("#F30000");
        }};
        craftTime = 250f;
    }},
    new Recipe() {{
        input = new IOEntry(){{
            items = Seq.with(
                Items.copper, 1
            );
        }};
        output = new IOEntry() {{
            items = Seq.with(
                Items.coal, 1
            )
            icon = () -> Icon.lock.uiIcon;
        }};
        craftTime = 120f;
    }}
);

icon: mono

switchStyle = RecipeSwitchStyle.simple;
resolvedRecipes = Seq.with(
    new Recipe() {{
        input = new IOEntry(){{
            items = Seq.with(
                Items.copper, 1
            );
        }};
        output = new IOEntry() {{
            items = Seq.with(
                Items.coal, 1
            )
        }};
        craftTime = 60f;
        icon = () -> UnitTypes.mono.uiIcon;
    }},
    new Recipe() {{
        input = new IOEntry(){{
            items = Seq.with(
                Items.copper, 1
            );
        }};
        output = new IOEntry() {{
            fluids = Seq.with(
                Liquid.ozone, 1f
            )
        }};
        craftTime = 60f;
    }}
);

• The icon variable as to be always defined by icon = () -> ...;
• For a built-in icon, it should start with Icon., such as Icon.lock-open or Icon.trash.
• For an icon from item, fluid, unit or block, it should be the content uiIcon, such as Units.mono.uiIcon,phase-heat.uiIcon.
• For any texture, it should be its name, such as your-mod-icon or alphaaaa.
