UnityEngine.AnimationCurve
- 創建：創建腳本掛載在物體上，定義public AnimationCurve curve；然后在Inspector面板就可以看到多了一個Curve，點開后可進行編輯
- 簡單使用：
public void Update()
{
transform.position = new Vector3(Time.time, anim.Evaluate(Time.time), 0);
}
- 再做一個簡單的案例：
利用曲線控制小球的運動軌跡和顏色
using UnityEngine;
public class curvetest : MonoBehaviour
{
public AnimationCurve curve;
public Color oldColor;
public Color newColor;
public float timeScale = 1;
bool startAnimation = false;
float startTime = 0;
float currentTime = 0;
Material mat;
void Start()
{
mat = transform.GetComponent<Renderer>().material;
Invoke("ChangeState", 2f);
}
void ChangeState()
{
startTime = Time.time;
startAnimation = true;
}
float CurrentTime
{
get
{
if (startAnimation)
{
currentTime = ((Time.time - startTime) * timeScale) % 1;
}
else
currentTime = 0;
return currentTime;
}
}
void Update()
{
if (startAnimation)
UpdateAnimation();
}
void UpdateAnimation()
{
transform.localPosition = new Vector3(0, curve.Evaluate(CurrentTime), 0);
mat.SetColor("_Color", Color.Lerp(oldColor, newColor, curve.Evaluate(CurrentTime)));
}
}
看完這段代碼，應該已經會使用AnimationCurve了，基于Curve我們還可以做更多的事情，許多的面片特效的插件就是通過用Curve來控制面片的scale和position來生成的，大家可以多多嘗試
