Question

JavaScript => static var Infinity: float;
C# => static float Infinity;

Description 描述

A representation of positive infinity (Read Only).

表示正无穷，也就是无穷大，∞ （只读）[in'finiti]

JavaScript:

// Casts a ray from (0,0,0) towards (0,0,1) to the infinity and prints a message
// if any object has touched the ray.
// To test it, just place any object and intersect it with the white drawn line
 
function Update () {
	// shows the line that follows the ray.
	Debug.DrawLine(Vector3.zero, Vector3.forward * 100);
	if (Physics.Raycast (Vector3.zero, Vector3.forward, Mathf.Infinity)) {
		print ("There is something in front of the object!");
	}
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Update() {
        Debug.DrawLine(Vector3.zero, Vector3.forward * 100);
        if (Physics.Raycast(Vector3.zero, Vector3.forward, Mathf.Infinity))
            print("There is something in front of the object!");
 
    }
