Instead, developers code some possibilities and let chance determine what happens when the player reaches a certain point in the map.

RNGs are used, for example, to live up open world games without the developers having to code every single section of forests and roads and deserts. In a video game, you can use a RNG to determine what kind of loot might be dropped by a fallen enemy, or what you can find in a chest, or what kind of random encounter will await you, or even what the weather will be.

There are many ways you can generate a Random Number, but how do you actually use one?īreaking it down into the simplest terms, using a RNG is not dissimilar from what you saw above with the dice throw used to determine an effect from a table. In video games, RNGs are much less noticeable and more complex, and players might not even be aware they exist. How Random Number Generators Work in Video Games

Here's the whole table.Īny game that uses dice has an analogic random number generator. Part of a table for random effects after drinking a potion. More complex games have manuals full of tables to determine something randomly. In this case there is a 1/16 or 6.25% chance of getting 0, 1/4 or 25% chance of getting 1, 3/8 or 37.5% chance of getting 2, 1/4 or 25% chance of getting 3 and 1/16 or 6.25% change of getting 4. There are 16 possible combinations, of which one gives a value of 0, 4 gives a value of 1, 6 gives a value of 2, 4 gives a value of 3, and one gives a value of 4. All the possible combinations obtained by throwing 4 dice, each can give a value of 0 or 1 Each die can give a value of 0 or 1 meaning that the value obtained by a single dice throw can go from 0 to 4. The oldest known tabletop game, the Royal Game of Ur, uses four 4-sided dice. Using multiple dice or coins instead will give a lower probability to the highest and lower values, and a higher probability to the middle values. Using a single die or coin means that each value has the same probability of occurring. The simplest form of a RNG is throwing dice or flipping coins. How an Analogic Random Number Generator Works In this article, we'll learn how random number generators work. RNGs, or Random Number Generators, are a way to introduce a touch of randomness and causality you need to spice it up. If everything is predictable in a game, that isn't much fun.
