Unity 视频总结(一) 初级编程

初级编程 – Unity Learn

• 输入 Input.GetKeyDown(KeyCode.R)
• 获取在组件并设置色彩 GetComponent().material.color = Color.green;
• update()函数是更新帧

using Unity巩立姣Engine;
using System.Collections;
public class ExamplgoogleeBehaviourScript : MonoBehaviour
{
void Update()
{
if (Input.GetKeyDown(KeyCode.R))
{
GetComponent<Renderer> ().material.color = Color.red;
}
if (Input.Get变量KeyDown(KeyCode.G))
{
Get变量英文Component&l变量的界说t;Renderer>().material.color =枸杞 Col宫颈癌or.green;
}
if (Input.GetKeyDown(KeyCode.B))
{
GetComponent<Rendere变量的界说r>().material.color = Color.blue;
}
}
}

• start函数是初步函数
• awake函数也是初步函数

using UnityEngine;
using System.Collections;
public clas变量英文s VariablesAndFunctions : MonoBehaviou宫颈癌r
{
int myInt = 5;
void Start ()
{
myInt = MultiplyByTwo(变量类型有哪些myInt);
Debug枸杞.Log (myInt);
}
int MultiplyByTwo (int number)
{
int变量之间的联系 ret;
ret = number * 2;
return ret;
}
}

• 这个时分的transform值自身

using UnityEngine;
using System.Collections;
public狗狗币 class BasicSyntax : MonoBehaviour
{
vGooid Start ()
{
Debug变量与函数.Log(transform.position.x);
if(t巩立姣ransform.position.y <= 5f)
{
Debug.Log ("I'm about to hit the ground!");
}
}
}

• Time.deltaTime 差距时间

using Un变量与函数ityEngine;
using S变量min表明什么类型的变量ystem.Collections;
public class IfStatements : MonoBehaviour
{
f宫颈癌loat coffeeTemperGoature = 85.0f;
float hotLimitTemperature = 70.0f;

Tem变量泵peratureTe巩立姣st();
coffeeTemperat宫颈癌ure -枸杞= Time.deltaTime * 5f;
}
void TemperatureTest ()
{
// 假定咖啡的温度高于最热的饮用温度...
if(c变量的界说offeeTemperature > hotLimitTemperature)
{
// ... 实施此操作。
print("Coffee is too hot.");
}
// 假定不是，但咖啡的温度低于最冷的饮用温度...
else if(c枸杞offeeTemperature < coldLimitTemperature)
{
// ... 实施此操作。
print("Coffee is too cold.");
}
// 假定两者都不是，则...
else
{
// ... 实施此操作。
print("Coffee is just right.");
}
}
}

• awake 即使没有变量类型有哪些启用脚本也能运转,首要是初始化引用
• star变量提高t 初次更新置前调用,一定需求启用脚本

using Unity变量min表明什么类型的变量Engine;
using Syste变量名的命名规矩m.Collections;
public class AwakeAndStart : MonoBehaviour
{
void Awake ()
{龚俊
Debug.Log("Awake called."宫颈癌);
}
void Start ()
{
Debu变量是什么意思g.Log("Start called."巩立姣);
}
}

{
Debug.Log("FixedUpdate time :" + Time.deltaTime);
}
void Upda变量min表明什么类型的变量te ()
{

• Input.GetKey(KeyCode.UpArrow) 这个不必GetKeyDown
• Vector3.forward 由所以局部坐标,所以可以这么弄

using Uni变量英文tyEngine;
using System.Collections;
public class TransformFunction变量是什么意思s : MonoBehaviour
{
public float moveSpeed = 10f;
public float turnSpeed = 50f;
void Update ()
{
if(Input.GetKey(KeyCod变量min表明什么类型的变量e.UpArrow))
transf变量类型有哪些orm.Translat工商银行客服电话e(Vector3.forward * move宫颈癌Speed * T公积金ime.deltaTime);
if(Input.GetKey(KeyCode.Down龚俊Arrow))
transform.Translate(-Vector3.forward * moveSp变量类型有哪些eed * Time.deltaTime);
if(Input.GetKey(KeyCode.LeftArrow))
transform.Rotate(Vector宫颈癌3.up,枸杞 -turnSpeed * Time.deltaTime);
if(Input.GetKey(KeyCod变量之间的联系e.RightArrow))
