Particle Effect Particle Property Expression

Particle effect particle property expression provides simple yet powerful way for particle to describe its property.

Property Expression

Each property output is computed based on its property expression, which is the sum of all property inputs multiplied by corresponding coefficient.

Take the following example:

json

{
    "x": {
        "c": 0.1,
        "cosr1": 0.2
    }
}

It will be transformed with the following logic:

ts

output.x = input.c * 0.1 + input.cosr1 * 0.2
