random

Returns a random real number between 0 and n.

Syntax:

GML Code Example

random(n);


Argument Description
n The upper range from which the random number will be selected.


Returns: Real


Description

This function is good for probabilities where returning an integer (whole number) is not necessary. For example, random(100) will return a value from 0 to 99, but that value can be 22.56473! You can also use real numbers and not integers in this function like this - random(0.5), which will return a value between 0 and 0.4999999.

NOTE: This function will return the same value every time the game is run afresh due to the fact that GameMaker: Studio generates the same initial random seed every time to make debugging code a far easier task. To avoid this behaviour use randomize at the start of your game.


Example:

GML Code Example

if random(10) >= 9
    {
    score += 100;
    }
 

This will produce approximately a one in ten chance of adding 100 to the score.
