我正在制作一款可以向坦克发射导弹的游戏。我希望导弹遵循这一轨迹:
我尝试了几件事,但是没有运气。有谁知道如何实现这一轨迹?
在此先感谢您的帮助。

您应搜索:弹道,加农炮,弹道物理,抛物线等。
以下是在变换时投篮的示例: https://answers.unity.com/questions/148399/shooting-a-cannonball.html
我现在没有打开Unity,所以我不能给您完整的代码。顺便说一句,尝试更改以下代码供您自己使用,并在注释中告知我。
function BallisticVel(target: Transform, angle: float): Vector3 {
var dir = target.position - transform.position; // get target direction
var h = dir.y; // get height difference
dir.y = 0; // retain only the horizontal direction
var dist = dir.magnitude ; // get horizontal distance
var a = angle * Mathf.Deg2Rad; // convert angle to radians
dir.y = dist * Mathf.Tan(a); // set dir to the elevation angle
dist += h / Mathf.Tan(a); // correct for small height differences
// calculate the velocity magnitude
var vel = Mathf.Sqrt(dist * Physics.gravity.magnitude / Mathf.Sin(2 * a));
return vel * dir.normalized;
}
var myTarget: Transform; // drag the target here
var cannonball: GameObject; // drag the cannonball prefab here
var shootAngle: float = 30; // elevation angle
function Update(){
if (Input.GetKeyDown("b")){ // press b to shoot
var ball: GameObject = Instantiate(cannonball, transform.position, Quaternion.identity);
ball.rigidbody.velocity = BallisticVel(myTarget, shootAngle);
Destroy(ball, 10);
}
}
