public Vector3 localScale ;

説明

The scale of the transform relative to the GameObjects parent.

If the localScale is changed on a child GameObject (but not the parent), only the child's scale will change. However, if the parent's localScale is changed, all the child GameObjects scale will change as well.

using UnityEngine;

public class ExampleClass : MonoBehaviour { public float x = 0.1f; public float y = 0.1f; public float z = 0.1f; void Update() { // Widen the object by x, y, and z values transform.localScale += new Vector3(x, y, z); } }
