  • Method Details

    • from

      public static IValueType[] from(IVariable... variables)
      Create a new value type array from the given variable array element-wise. If a variable would be null, that corresponding value type would be null as well.
      Parameters:
      variables - The variables.
      Returns:
      The value types array corresponding element-wise to the variables array.

    • from

      public static IValueType<?>[] from(IVariableFacade... variableFacades)
      Create a new value type array from the given variableFacades array element-wise. If a variableFacade would be null, that corresponding value type would be null as well.
      Parameters:
      variableFacades - The variables facades.
      Returns:
      The value types array corresponding element-wise to the variables array.

    • from

      public static net.minecraft.network.chat.Component[] from(IValueType<?>... valueTypes)
      Create a new unlocalized name array from the given variableFacades array element-wise.
      Parameters:
      valueTypes - The value types.
      Returns:
      The unlocalized names array corresponding element-wise to the value types array.

    • evaluateOperator

      public static IValue evaluateOperator(IOperator operator, IVariable... variables) throws EvaluationException
      Evaluate an operator for the given variables.
      Parameters:
      operator - The operator.

      Returns:
      The resulting value.
      Throws:

    • serializeRaw

      public static void serializeRaw(net.minecraft.world.level.storage.ValueOutput valueOutput, IValue value)
      Serialize the given value to a raw tag without its value type.
      Parameters:
      valueOutput - The value output.
      value - The value.

    • serialize

      public static void serialize(net.minecraft.world.level.storage.ValueOutput valueOutput, IValue value)
      Serialize the given value.
      Parameters:
