Should you need to keep a consistent value over a number of runs of a game, you should be using random_set_seed(). Please note, that when using the random number functions in GameMaker the initial seed is always the same, as this makes tracing errors and debugging far easier.
This function returns a random floating-point (decimal) number between 0.0 (inclusive) and the specified upper limit (inclusive). For example, random(100) will return a value from 0 to 100.00, but that value can be 22.56473!
Now that we've covered the essentials of PRNGs, we will start using GameMaker's built-in random number generator, understanding the different functions available and exploring possible pitfalls. We'll start by generating a uniform random integer within a range. Say, for example, we need to simulate a fair six-sided die roll.
14 Απρ 2015 · In GameMaker Studio and GameMaker 8.1 there is a function: random_set_seed(seed) Here you can enter your seed. Then random(x) gives the same n-th result per game run.
Random Numbers and Values. NOTE When using the random functions, GameMaker maintains the same random seed every time you start the game.
This is a way to get a random number without repetition: First, you initialize a list with how many numbers do you want: global.number_list = ds_list_create() var i = 0; repeat(10) { // the random number you will get will be from 0 to 10 ds_list_add(global.number_list, i) i++; } ds_list_shuffle(global.number_list);
RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.
