In game programming, which term describes the use of a randomizing mechanism to determine movement, such as a spin of a six-number randomizer?

• A. Deterministic
• B. Randomizer
• C. Pseudorandom
• D. Constant

Answer: (B)

The key idea here is introducing randomness through a device or function that produces a random value to drive movement. A randomizer is exactly that piece—the mechanism that yields a random result, like spinning a six-sided die to decide how far or in which direction to move. In games you often implement this with a random number generator, which is typically pseudorandom: it uses an algorithm (and often a seed) to produce numbers that appear random but can be reproduced if you know the seed. However, the term that best describes the mechanism that provides the randomness itself is randomizer. Deterministic means outcomes are fixed given the inputs, constant means a fixed value, and pseudorandom refers to the nature of the numbers produced rather than the mechanism used to introduce randomness.
