Module rand 

Implementations and uses of Pseudo-RNG in Geometry Dash.

Functions

check_seed_advanced_random

Determines the group that an advanced random trigger will activate based on an input seed and a list of the trigger’s activation probabilities per group as a GDValue::ProbabilitiesList.

check_seed_random

Checks if the seed will activate group 1 or 2 in a random trigger. The chance must be given as a float in the range [0.0, 1.0]. The function returns true if the group 1 will be activated, and false if group 2 will be activated.

fast_rand_bits

Function used by GD to generate a new seed. Internally known as fast_rand_0_1. Unlike the actual PRNG used in GD, this function DOES NOT automatically update the seed.

fast_rand_bits_norm

Utility function which normalises result from fast_rand_bits to the range [0.0, 1.0].

next_seed

Determines the next seed from a starting seed as generated in Geometry Dash.

next_seed_mut

Mutating version of next_seed
