Unity 3D学习日记（2）

Day2

1.实例化用Instantiate(要生成的物体，生成的位置，旋转角度)

2.检测鼠标左键并生成物体 If(Input.GetButtonDown(“Fire1”)){
Transform n = Instantiate(newobeject,transform.position,transform.rotation);
}

3.给物体加力 n.rigibody.AddForce(fwd*28000);

4.转换方向 Vector3代表xyz
Vector3 fwd=transform.TransformDirection(Vector3.forward);
Vector3.forward=>(0,0,1)

5.销毁物体 Destroy(gameObject,3.0);

6.多行注释/* */

7.对变量赋予物体， Inspector中直接拖

8.旋转物体 Input.GetKEy(KeyCode.Q){
transform.rotate(0,-25*Time.deltaTime,0,Space.Self);
}
Space.Self以自身轴旋转
25*Time.deltaTime
KeyCode.X不可用小写

9.走到地下问题，沿x轴旋转
Input.GetKEy(KeyCode.Z){
transform.rotate(-25*Time.deltaTime,0,0,Space.Self);
}

10.GUI Text(Unity 3d 5.0后变为UI-Text)

    //Rotate in Y using Q and E
    if(Input.GetKey(KeyCode.Q)){
        transform.Rotate (0,-25*Time.deltaTime,0,Space.Self);
    }
    if(Input.GetKey(KeyCode.E)){
        transform.Rotate (0,25*Time.deltaTime,0,Space.Self);
    }

    //Rotate in X using Z and C
    if(Input.GetKey(KeyCode.Z)){
        transform.Rotate (-25*Time.deltaTime,0,0,Space.Self);
    }
    if(Input.GetKey(KeyCode.C)){
        transform.Rotate (25*Time.deltaTime,0,0,Space.Self);
    }

    //Raise or down camera
    if (Input.GetKey (KeyCode.H)) {
        transform.Translate (0,speed*Time.deltaTime,0);
    }
    if (Input.GetKey (KeyCode.N)) {
        transform.Translate (0,-speed*Time.deltaTime,0);
    }
