Unity basic C # access between game objects

Script Language: C #

 

1. Create two objects in the Unity project: Cube and sphere.

2. Add the cubescript and spherescript for the cube and sphere respectively:

In spherescript, the two define a function dosomething (). The specific code of the script is as follows:

using UnityEngine;using System.Collections;public class SphereScript : MonoBehaviour {    public int radius = 5;    // Use this for initialization    void Start () {    }        // Update is called once per frame    void Update () {    }    public void DoSomething(){        Debug.Log("Hello ~");    }}

 

3. Access the sphere of an object in the cubescript script to change its color to red, and access the dosomething function in the spherescript. The specific code is as follows:

Using unityengine; using system. collections; public class cubescript: monobehaviour {// use this for initialization void start () {spherescript A = NULL; // obtain spherescript script a = gameobject. find ("sphere "). getcomponent <spherescript> (); debug. log ("spherescript's a =" +. radius); debug. log ("spherescript's function Domething:"); // call the function a of the spherescript. dosomething ();} // update is called once per frame void Update () {gameobject target = NULL; // access sphere to reference object target = gameobject. find ("sphere"); // Changes the color of the sphere to red target. renderer. material. color = color. red ;}}
