CustomCollider2D.ClearCustomShapes

描述

从碰撞器中删除所有形状及其关联的顶点。

此碰撞器的任何现有接触将在下一个模拟步骤中重新计算。

using UnityEngine;
using UnityEngine.Assertions;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Fetch the custom collider.
        var customCollider = GetComponent<CustomCollider2D>();

        // Create a shape group.
        var shapeGroup = new PhysicsShapeGroup2D();

        // Add 5 Circles to the shape group.
        shapeGroup.AddCircle(center: new Vector2(3f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(4f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(5f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(6f, 0f),  radius: 0.5f);
        shapeGroup.AddCircle(center: new Vector2(7f, 0f),  radius: 0.5f);

        // Assign our shapes.
        customCollider.SetCustomShapes(shapeGroup);

        // Validate the contents of the custom collider.
        Assert.AreEqual(5, customCollider.customShapeCount);

        // Clear all the remaining shapes.
        customCollider.ClearCustomShapes();

        // Validate the contents of the custom collider.
        Assert.AreEqual(0, customCollider.customShapeCount);
    }
}

参数

描述

删除从 shapeIndex 开始的由 shapeCount 定义的特定数量的形状，以及这些形状使用的所有关联顶点。

此碰撞器的任何现有接触将在下一个模拟步骤中重新计算。
