Use Unity to build high-quality 3D and 2D games, deploy them across mobile, desktop, VR/AR, consoles or the Web, and connect with loyal and enthusiastic players and customers. Then there are the gradient noise and fixed pattern bayer or Halton series "noise" options. Unity is the ultimate game development platform. Though there are a handful of examples of real-time psuedo blue noise on ShaderToy as well you can look at if you search. There's also perlin and simplex noise and the like, which can be based off of various hash functions. Here's a site with a generator, as well as links to a ton of pregenerated blue noise textures of various sizes and formats: Unity's own post processing shaders use blue noise textures now almost exclusively. However it's fairly well accepted that the best quality noise you can get is some form of blue noise, and for that you will need to use a texture as it's much too expensive to calculate on the fly. Most are using some form of simple trigonometry free (no sin or cos) hash with multiple octaves which end up being similar in perf to the example above, but significantly higher quality.ĭepending on your needs, any of them might work well enough, even with out multiple octaves. This is how to use the function - Random.Range (min,max) - to generated randomized numbers and then use them as red,green,blue values to create an unexpected color If you think this. The link I posted of a ShaderToy search has a ton of different example noise, or hash functions, often with discussions in the comments about implementations and their various pros and cons. It's also pretty darn terrible both in quality and in performance (vs other similar quality noise functions). Random.Range with integers does not include the upper limit, so it will never hit 3 in your case. This can often be an effective way to reduce a game's storage requirements - you can generate as many levels as you like procedurally and store each one using nothing more than an integer seed value.The noise function posted above is a super common example that you'll find in plenty of shaders or there in the wild, and threads on the internet. Color class uses 0-1 values, you probably should use Color32, or switch to using 0-1. This will make sure that the same "random" pattern is produced each time the game is played. You can use randomly-chosen elements to make the scene look arbitrary and natural but set the seed to a preset value before generating. You might set your own seed, for example, when you generate a game level procedurally. However, it is sometimes useful to produce the same run of pseudo-random values on demand by setting the seed yourself. This prevents the same run of values from occurring each time a game is played and thus avoids predictable gameplay. The seed is normally set from some arbitrary value like the system clock before the random number functions are used. The point in the sequence where a particular run of pseudo-random values begins is selected using an integer called the seed value. A simply way to achieve this is to connect a Texture Coordinates node into its input. NOTE: Input data must vary across the the geometry since equal values will generate the same noise.

Enter the values for your maze design below and click the 'Generate Maze' button. The random number generator is not truly random but produces numbers in a preset sequence (the values in the sequence "jump" around the range in such a way that they appear random for most purposes). The Noise Generator node creates a Float noise value on a -1 1 range using the method specified by Type according to a value specified at UV.
