But there are easier functions to use than this. First, call Randomize() (this is important because it will randomize the "seed" your program uses for random stuff, or else you will always get the same results in the same order) For example, I have an array, and each value in the array has a Esta página lo guía a través de los tipos comunes de aleatoriedad y cómo implementarlos en Godot. To get a random element from an array faster, use the following instead: # Make sure to call `randomize ()` once (and only once) in a script's `_ready ()` function first. randi_range(1, 2730) I built a tiny RNG class with a few functions and have it in autoload to be able to get random numbers within certain ranges everywhere in my project. One question tho: Isnt the number of values in an array supposed to be predetermined?
