Class MathHelper

java.lang.Object
net.minecraft.util.math.MathHelper
public class MathHelper extends Object
Contains math-related helper methods. This includes float-specific extensions to Math, linear interpolation (lerp), and color-related methods.

Trigonometric functions defined in this class use the "sine table", a pre-calculated table of sin(N) (0 <= N < pi * 2).

    • ROUNDER_256THS

      private static final double ROUNDER_256THS
      A constant for rounding a double to the nearest multiple of 1/256.

      When this constant is added to a double that is not too large, then the bits of the result's mantissa reflect the original number times 256. Consequently, adding this constant and then subtracting it rounds such doubles to the nearest multiple of 1/256.

      This is used by atan2(double, double) to produce an index into ARCSINE_TABLE and COSINE_OF_ARCSINE_TABLE.

      Returns:
      an approximation of Math.atan2(y, x)
      Implementation Note:
      This implementation transforms the arguments such that they lie in the first quadrant. If y > x, then x and y are swapped to minimize the error of the initial approximation. x and y are normalized, and an initial approximation of the result and the sine of the deviation from the true value are obtained using the ARCSINE_TABLE and COSINE_OF_ARCSINE_TABLE lookup tables. The error itself is approximated using the third-order Maclaurin series polynomial for arcsin. Finally, the implementation undoes any transformations that were performed initially.

    • binarySearch

      public static int binarySearch(int min, int max, IntPredicate predicate)
      Finds the minimum value in [min, max) that satisfies the monotonic predicate.

      The predicate must be monotonic, i.e. if for any a, predicate.test(a) is true, then for all b > a, predicate.test(b) must also be true.

      Examples:

      • binarySearch(3, 7, x -> true) returns 3.
      • binarySearch(3, 7, x -> x >= 5) returns 5.
      • binarySearch(3, 7, x -> false) returns 7.
      Parameters:
      min - the minimum value (inclusive) to be tested
      max - the maximum value (exclusive) to be tested
      predicate - the predicate that returns true for integers greater than or equal to the value to be searched for
      Returns:
      the minimum value if such value is found, otherwise max

    • catmullRom

      public static float catmullRom(float delta, float p0, float p1, float p2, float p3)
      Interpolates a point on a Catmull-Rom Spline. This spline has a property that if there are two splines with arguments p0, p1, p2, p3 and p1, p2, p3, p4, the resulting curve will have a continuous first derivative at p2, where the two input curves connect. For higher-dimensional curves, the interpolation on the curve is done component-wise: for inputs delta, (p0x, p0y), (p1x, p1y), (p2x, p2y), (p3x, p3y), the output is (catmullRom(delta, p0x, p1x, p2x, p3x), catmullRom(delta, p0y, p1y, p2y, p3y)).
      Parameters:
      delta - the progress along the interpolation
      p0 - the previous data point to assist in curve-smoothing
      p1 - the output if delta is 0
      p2 - the output if delta is 1
      p3 - the next data point to assist in curve-smoothing
