Description

The size of the box, measured in the object's local space.

Use this to return or set the size of the BoxCollider component of a GameObject. Unity measures the size in the GameObject's local space. Changing the BoxCollider size scales it by the Transform’s scale.

no example available in JavaScript
//Attach this script to a GameObject. Make sure the GameObject has a BoxCollider component (Unity Cubes have these automatically as long as they weren’t removed).
//Create three Sliders ( Create>UI>Slider). These are for manipulating the x, y, and z values of the size.
//Click on the GameObject and attach each of the Sliders to the fields in the Inspector.
//In Play Mode, click the GameObject and enable Gizmos to visualize the BoxCollider.

using UnityEngine; using UnityEngine.UI;

public class Example : MonoBehaviour { //Make sure there is a BoxCollider component attached to your GameObject BoxCollider m_Collider; float m_ScaleX, m_ScaleY, m_ScaleZ; public Slider m_SliderX, m_SliderY, m_SliderZ;

void Start() { //Fetch the Collider from the GameObject m_Collider = GetComponent<BoxCollider>(); //These are the starting sizes for the Collider component m_ScaleX = 1.0f; m_ScaleY = 1.0f; m_ScaleZ = 1.0f;

//Set all the sliders max values to 20 so the size values don't go above 20 m_SliderX.maxValue = 20; m_SliderY.maxValue = 20; m_SliderZ.maxValue = 20;

//Set all the sliders min values to 1 so the size don't go below 1 m_SliderX.minValue = 1; m_SliderY.minValue = 1; m_SliderZ.minValue = 1; }

void Update() { m_ScaleX = m_SliderX.value; m_ScaleY = m_SliderY.value; m_ScaleZ = m_SliderZ.value;

m_Collider.size = new Vector3(m_ScaleX, m_ScaleY, m_ScaleZ); Debug.Log("Current BoxCollider Size : " + m_Collider.size); } }
