# 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:

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

It will be transformed with the following logic:

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