Im making a game where you can fire missiles at tanks. I want the missile to follow this trajectory:

I have tried a few things but no luck. Does anyone has an idea on how I could achieve this trajectory?

Thanks in advance for any help.

You should search for: ballistics, cannon, ballistics physics, ball parabola, etc.

Here is an example of of shooting ball at transform:

I don't have Unity open right now, so I can't give you full code. By the way, try to change the code below for your own use and let me know in comments.

 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);

     }

 }
