Unity版本捕鱼游戏设计与实现
经典的射击小游戏:捕鱼达人
灵魂画师上线:
这是比较直白的草图也叫灵魂图，中间大方框周围的小方框代表鱼的生成位置，鱼通过这七个点来生成，并且游向屏幕中央，
来让玩家看到这种效果：
而单纯的只给鱼向前游是不行的，那样看着会很机械，所以要模仿鱼的左右移动，也就是弧线移动。
弧线移动的实现方式也很简单，说白了就是让他边扭着身子边直线跑，这样就是弧线移动了。
把这两个运动分解成可以复用的两个脚本，一个直线移动，一个掌控自身的增量旋转。

namespace JumpAgent
{
public class FishMaker : MonoBehaviour
{
public Transform[] genPositions;//鱼的生成位置
public GameObject[] fishPrefabs;//所有鱼的预制体
public Transform fishHolder;//收纳鱼的clone,防止散乱
private void Start()
{
InvokeRepeating("MakeFish", 0, 0.1f);
}
void MakeFish()
{
//在什么位置生成什么鱼
int genPosIndex = Random.Range(0, genPositions.Length);
int fishPreIndex = Random.Range(0, fishPrefabs.Length);
//获取鱼的最大生成数量和最大速度
int maxNum = fishPrefabs[fishPreIndex].GetComponent().maxNuml;
int maxSpeed = fishPrefabs[fishPreIndex].GetComponent().maxSpeed;
//决定鱼的生成数量和速度
int num = Random.Range((maxNum / 2) + 1, maxNum);
int speed = Random.Range(maxSpeed / 2, maxSpeed);
//鱼的行为轨迹,0代表直线,1代表弧线
int moveType = Random.Range(0, 2);
//直走的倾斜角
int angOffset;
//转弯速度
int angSpeed;
if (moveType == 0)
{
//直线鱼
angOffset = Random.Range(-22, 22);
StartCoroutine(GreatLineFish(genPosIndex, fishPreIndex, num, speed, angOffset));
}
else
{
//弧线
angSpeed = Random.Range(8, 13);
int direct= Random.Range(0, 2);
if (direct==0)
{
StartCoroutine(GreatcurveFish(genPosIndex, fishPreIndex, num, speed, angSpeed));
}
else
{
StartCoroutine(GreatcurveFish(genPosIndex, fishPreIndex, num, speed, angSpeed));
}
}
}
IEnumerator GreatLineFish(int genPosIndex, int fishPreIndex, int num, int speed, int angOffset)
{
for (int i = 0; i < num; i++)
{
GameObject fish = GameObject.Instantiate(fishPrefabs[fishPreIndex]);
fish.transform.SetParent(fishHolder, false);
fish.transform.localPosition = genPositions[genPosIndex].localPosition;
fish.transform.localRotation = genPositions[genPosIndex].localRotation;
fish.transform.Rotate(0, 0, angOffset);
fish.GetComponent().sortingOrder += i;
fish.AddComponent().speed = speed;
yield return new WaitForSeconds(0.5f);
}
}
IEnumerator GreatcurveFish(int genPosIndex, int fishPreIndex, int num, int speed, int angSpeed)
{
for (int i = 0; i < num; i++)
{
GameObject fish = GameObject.Instantiate(fishPrefabs[fishPreIndex]);
fish.transform.SetParent(fishHolder, false);
fish.transform.localPosition = genPositions[genPosIndex].localPosition;
fish.transform.localRotation = genPositions[genPosIndex].localRotation;
fish.GetComponent().sortingOrder += i;
fish.AddComponent().speed = angSpeed;//添加旋转组件
fish.AddComponent().speed = speed;//添加移动组件
yield return new WaitForSeconds(0.5f);
}
}
}//类
}//命名空间 再然后是：炮台，子弹，网
首先，炮台会跟随我们的手指的输入坐标来进行转动，然后，是炮台的伤害，炮台的伤害根据我们所选择的伤害来执行，也就是操作一个int类型的伤害数组，然后可以把这个伤害数组里面的元素平均分组，然后每到一个分组里就给我们的换一个炮台（隐藏和显示）。
其次，我们的炮台发射子弹是要钱的，根据不同的金额，对鱼造成不同的伤害，当时并不是直接通过子弹对其造成伤害，是炮台放出去子弹，子弹碰到鱼，然后在子弹处生成网子，在把子弹应该造成的伤害赋值给网子，网子存在一定时间，然后由网子再和鱼做碰撞检测，每个enter进去的鱼都会收到网子发送给鱼的伤害，也就是说每次鱼碰到网子生命值都会减少，直到鱼死亡。
再根据每只鱼的死亡，去更新相应的UI数据即可。

最后是我去除了限制炮台发射速度的效果，因为这样比较爽：
