public ParticleSystemScalingMode scalingMode;

Description

Control how the Particle System applies its Transform component to the particles it emits.

Hierarchy: Scale according to its Transform and all its parents. Local: Scale using only its own Transform, ignoring all parents. Shape: Only apply scale to the source positions of the particles, but not their size. The source positions are defined by the Shape module.

void Start() { ps = GetComponent<ParticleSystem>(); }

void Update() { ps.transform.localScale = new Vector3(sliderValue, sliderValue, sliderValue); if (ps.transform.parent != null) ps.transform.parent.localScale = new Vector3(parentSliderValue, parentSliderValue, parentSliderValue);
