2.14 unity特效渲染

day14 Unity特效渲染

一,粒子系统

在层级视图当中创建空白对象，然后给其添加组件Compnent—Effects—Particle System.

二,拖尾渲染

组件:TrailRenderer

三,线 性 渲 染

代码:

自动导航的描点

public LineRenderer line;

NavMeshAgent agent;

public Transform[] targets;

int index = 0;

NavMeshPath path;//保存导航路径

void Start () {

agent = GetComponent<NavMeshAgent>();

agent.SetDestination(targets[index].position);

path = new NavMeshPath();

}

// Update is called once per frame

void Update () {

if (agent.remainingDistance<=agent.stoppingDistance)

{

index++;

index %= targets.Length;

agent.SetDestination(targets[index].position);

}

DrawPath();

}

void DrawPath()

{

//判断是否能计算导航路径

bool res = agent.CalculatePath(agent.destination,path);

if (res)

{

//获取路径的拐点

Vector3[] corners= path.corners;

//设置line的顶点数

line.positionCount = corners.Length + 2;

line.SetPosition(0, transform.position);

for (int i = 0; i < corners.Length; i++)

{

line.SetPosition(i + 1, corners[i]);

}

line.SetPosition(corners.Length + 1,agent.destination);

}

}
