Overview

This numerical property controls the radius of particles. This value is 1.0 by default.

Gotchas

If you change the radius during execution, existing particles may explode, shrink, or behave unexpectedly.

Example

local particleSystem = physics.newParticleSystem(
    {
        filename = "particle.png",
        radius = 2
    }
)

particleSystem.particleRadius = 3.0
