Function randomSeed

Generates a random scalar seed.

The function can be useful together with the randomization modifiers for properties:

• RandomDeltaModifier
• RandomRangeModifier
• RandomFractionModifier

Or the functions that generate simple properties with these modifiers:

• RandomDeltaProperty
• RandomRangeProperty
• RandomFractionProperty

To link multiple random values, so that they change the same amount if randomized at the same time, you can use this function to generate a seed that you can use multiple times. For example:

const seed = randomSeed()
new PointLight({
  separateSpecular: true,
  diffuseMultiplier: RandomDeltaProperty(1, 5, seed),
  specularMultiplier: RandomDeltaProperty(1, 5, seed),
})
Copy

Here, the point light that was created will randomize to have the same specular multiplier as its diffuse multiplier. This example is not the best, because this could also have been done by setting separateSpecular to false, but it should at least show how this functions.

Generates a random seed of the given type.

To link multiple random values, so that they change the same amount if randomized at the same time, you can use this function to generate a seed that you can use multiple times. For example:

const seed = randomSeed(ValueType.Vector4)
new PointLight({
  separateSpecular: true,
  diffuseColor: RandomDeltaProperty([1, 1, 1, 1], [0.5, 0.5, 0.5, 0], seed),
  specularColor: RandomDeltaProperty([1, 1, 1, 1], [0.5, 0.5, 0.5, 0], seed),
})
Copy

Here, the point light that was created will randomize to have the same specular color as its diffuse color. This example is not the best, because this could also have been done by setting separateSpecular to false, but it should at least show how this functions.
