鱼的移动和方向转换
usingUnityEngine;
usingSystem.Collections;
publicclassFishMove:MonoBehaviour{
publicfloatfishSpeed;
privateVector3startPos;//开始位置
privateVector3targePos;//目标位置
voidStart(){
startPos=transform.position;
GetTarget();
if(transform.position.x>0.0f){
ChangeDirection();
}
}
voidUpdate(){
if(Vector3.Distance(transform.position,targePos)<=0.05f){
ChangeDirection();
//更改起始点和目标点
startPos=targePos;
GetTarget();
}
MoveToTarget();
}
//移动
voidMoveToTarget(){
transform.position=Vector3.MoveTowards(transform.position,targePos,fishSpeed*Time.deltaTime);
}
//获取目标点
voidGetTarget(){
targePos=newVector3(startPos.x*-1,startPos.y,0);
}
voidChangeDirection(){
//1.
transform.Rotate(newVector3(0,180,0));
//2.
//Vector3scale=transform.localScale;
//scale.x=-scale.x;
//transform.localScale=scale;
}
}
用委托来监视鱼的生命值
usingUnityEngine;
usingSystem.Collections;
publicclassFishLife:MonoBehaviour{

publicfloathp;//鱼的生命值
publicdelegatevoidFishDelegate();
publiceventFishDelegatefishEvent;
voidStart(){
}
voidUpdate(){
}
voidOnTriggerEnter2D(Collider2Dother){
//减血
hp-=other.gameObject.GetComponent().attack;
//子弹消失
if(other.name.Contains("fire")){
Destroy(other.gameObject);
}
if(hp<=0){
//产生爆炸效果
GameObjectexplosion=Instantiate(explosionPrefabs,transform.position,Quaternion.identity)asGameObject;
fishEvent();
Destroy(gameObject);
}
}
}
usingUnityEngine;
usingSystem.Collections;
publicclassGameController01:MonoBehaviour{
privatestring[]fishName;
privatefloattime;
privateintkillNumber;
privatefloattime_1;
voidStart(){
fishName=newstring[]{"fish1","fish2","fish3"};
}
voidUpdate(){
time+=Time.deltaTime;
if(time>=1.5f){
CreatFish();
time=0.0f;
}
}
voidCreatFish(){
intfishIndex=Random.Range(0,3);
//从资源文件夹Resources获取预设体
GameObjectfishPrefabs=Resources.Load(fishName[fishIndex])asGameObject;
intx_Dic=Random.Range(0,2);
floaty=Random.Range(-2,5.84f);
Vector3fishCreatPos;
if(x_Dic==0){
fishCreatPos=newVector3(-13.66f,y,0);
}else{
fishCreatPos=newVector3(13.66f,y,0);
}
GameObjectfish=Instantiate(fishPrefabs,fishCreatPos,Quaternion.identity)asGameObject;
fish.GetComponent().fishEvent+=ShowDate;
}
voidShowDate(){
killNumber++;
print(killNumber);
if((Time.time-time_1)<=1.0f){
}
time_1=Time.time;
}
}
用鼠标控制炮台的旋转
usingUnityEngine;
usingSystem.Collections;
publicclassCannonScript:MonoBehaviour{
publicGameObjectbulletPrefabs;//子弹预设体
publicTransformshootPos;//获得子弹发射位置
voidStart(){
}
voidUpdate(){
FollowMouseRotation();
if(Input.GetMouseButtonDown(0)){
Shoot();
}
}
voidShoot(){
GameObjectbullet=Instantiate(bulletPrefabs,shootPos.position,transform.rotation)asGameObject;
}
voidFollowMouseRotation(){
Vector3mousePos=Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector3direction=mousePos-transform.position;
direction.z=0;
//限制旋转角度
if(direction.y>0.2f){
//让自身坐标的Y轴指向当前方向
transform.up=direction;
}
}
}
usingUnityEngine;
usingSystem.Collections;
publicclassbulletScript:MonoBehaviour{
publicfloatattack;
privateRigidbody2Drig2D;
voidStart(){
rig2D=GetComponent();
}
voidUpdate(){
rig2D.AddForce(transform.up*1,ForceMode2D.Impulse);
}
}
usingUnityEngine;
usingSystem.Collections;
publicclassexplosionScript:MonoBehaviour{
//Usethisforinitialization
voidStart(){
}
//Updateiscalledonceperframe
voidUpdate(){

voidDead(){
Destroy(gameObject);
}
}
