|-||====== ZDoom RNG myths ======|
|-||Many modders are convinced that ZDoom's [[zdoom>Random]] function is not statistically random, or returns the same sequence of random numbers in different games. As a result, some mods try to enhance the randomness by creating a custom RNG that factors in [[zdoom>Timer]] or actor positions, or combines multiple calls to [[zdoom>Random]], and use it throughout the mod.|
|-||While this non-randomness of [[zdoom>Random]] was probably true previously, it is not anymore. Zandronum 2.0+ and GZDoom 1.8.6+ (as verified, likely earlier versions too) use high-quality statistically random [[wp>Mersenne Twister]] RNG and don't output the same sequence in different games or rounds.|
|-||Therefore, "enhancing" the RNG will only likely make it **less** random in modern versions of source ports. It is recommended to remove any custom RNG code from mods.|
