## Fields

- [`Frame`](/api/Sandbox.ParticleFloat.EvaluationType/Frame): Evaluates the value based on the current frame, introducing randomness for dynamic effects.
- [`Life`](/api/Sandbox.ParticleFloat.EvaluationType/Life): Evaluates the value based on the lifetime using its normalized age.
- [`Particle`](/api/Sandbox.ParticleFloat.EvaluationType/Particle)
- [`Seed`](/api/Sandbox.ParticleFloat.EvaluationType/Seed): Evaluates the value based on a random seed. This means that in most situations, it's random per context. Like if this is on a particle, the value will be random per particle.
