First Person shooter Game summary overview

This game small item for first person shooter game

is divided into several steps:

One: The production of the protagonist

1. Control the implementation of the main character movement

Points:

Understanding of Character Controller components

Understanding of Rigidbody Components

Colider and Rigidbody's understanding

Using code to control the movement of the protagonist--The realization of keyboard interaction

　　　　

    //Operation lead Movement//define 3 values to control movement        floatXM =0, ym =0, ZM =0; //move up or down        if(Input.getkey (KEYCODE.W)) {ZM+ = M_movspeed *Time.deltatime; }        Else if(Input.getkey (KEYCODE.S)) {ZM-= M_movspeed *Time.deltatime; }        if(Input.getkey (Keycode.a)) {XM-= M_movspeed *Time.deltatime; }        Else if(Input.getkey (KEYCODE.D)) {XM+ = m_movspeed*Time.deltatime; }

Also paste in the player the definition of some variables, to help define

//Transform Components     PublicTransform M_transform; //Role Controller ComponentsCharactercontroller m_ch; //character Move Speed    floatM_movspeed =3.0f; //Gravity    floatM_gravity =2.0f; //Health Value     Public intM_life =5;

　　　　

Display an icon for the protagonist in the editor: because the previous implementation of the protagonist is through a gameobject->empty to add the character controller to achieve, so in order to make it easier to edit, we use a picture in the editor to represent the protagonist, This image can only be displayed in the editor, the code is as follows:

void Ondrawgizmos () {    Gizmos.drawicon (this. Transform.postion,"spawn.tif" );}

　　

2. Bind the camera

Define the camera's properties first

// Camera Transform     Transform m_camtransform;     // Camera Rotation Angle     Vector3 M_camrot;     // camera height (lead height)    float 1.4f;

3. Binding

The next step is to bind the camera position to the direction and lead.

First: initialization of camera position and orientation in start function

　　

void Start () {  //Get the initial position of the camera      m_camtransform=camera.main.transform;       The initial position of the camera is consistent with the initial position of the protagonist    Vector3 pos=m_transform.postion;    Pos.y+=m_camheight;    m_camtransform.postion=pos;//the camera toward the main character    M_camtransform.rotation=m_transform.rotation;  M_camrot=m_camtransform.eulerangles;    Lock cursor
Screen.lockcursor=true;
}

In addition, with regard to cursor locking, the so-called cursor lock

　　　　

Here is a question, is transform.rotation and eulerangles problem, here some do not understand, leave first, later solve

Next, the camera position and orientation are updated at any time in the update () function, keeping it consistent with the protagonist's position.

  //get mouse Move distance        floatRH = Input.getaxis ("Mouse X"); floatRV = Input.getaxis ("Mouse Y"); //Rotating CameraM_camrot.x-=RV; M_camrot.y+=RH; M_camtransform.eulerangles=M_camrot; //The orientation of the protagonist is consistent with the cameraVector3 Camrot =M_camtransform.eulerangles; Camrot.x=0; Camrot.z =0; M_transform.eulerangles=Camrot; //protagonist Mobile Code//Align the camera position with the main characterVector3 pos =m_transform.position; Pos.y+=M_camheight; M_camtransform.position= pos;
