パラメーター

説明

Sets the radius of a shape.

using UnityEngine.Assertions;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Create a shape group.
        var shapeGroup = new PhysicsShapeGroup2D();

        // Add a Circle to the shape group.
        var shapeIndex = shapeGroup.AddCircle
            (
                center: Vector2.zero,
                radius: 0.5f
            );

        // Fetch the Circle shape and validate the radius.
        var physicsShape = shapeGroup.GetShape(shapeIndex);
        Assert.AreApproximatelyEqual(0.5f, physicsShape.radius);

        // Update the Circle radius.
        shapeGroup.SetShapeRadius(shapeIndex, 2f);

        // Fetch the Circle shape and validate the radius.
