Non random procedural generation

Hi, I’m new to coding in Unity and mainly interested in experimenting with procedural generation. I wanted to ask if there is a command to generate pseudo-random numbers based on a specific number input that will give the same result every time the same number input is given? I have seen the PerlinNoise function but this appears to give different output every time. Many thanks

Yes, any PRNG will do that if you seed it. See Random.seed, or try System.Random.
