Class RobotMath

java.lang.Object

robocode.util.RobotMath

public final class RobotMath
extends Object

Used internally by Robocode for making the random numbers of robots deterministic, when Robocode is set up for deterministic battles, e.g. with the RANDOMSEED system property or in tests.

When robot classes are loaded, calls to Math.random() and StrictMath.random() are replaced with calls to random(), which uses the random number generator of Robocode. With Java 8, Robocode replaced the random number generator of the Math class instead, but this is not possible with newer Java versions. Robots should not use this class directly.
