【Unity】抛物线公式

先上公式
public static Vector3 Parabola(Vector3 start, Vector3 end, float totalTime, float curTime) { //var g = 9.8f; var g = 50f; var halfTime = totalTime / 2f; var vec = (end - start) / totalTime; var initVelocity = vec + new Vector3(0, g * halfTime, 0); var acc = new Vector3(0, -g, 0); var curPos = start + initVelocity * curTime + 1f / 2f * acc * curTime * curTime; return curPos; }
使用方法，这里我用的是协程
float totalTime = 0.5f; float startTime = Time.time; while (true) { if (Time.time > startTime + totalTime) { break; } var curTime = Time.time - startTime; goGrenade.transform.position = MathTool.Parabola(startPos, targetPos, totalTime, curTime); yield return null; }
