Jump trajectory | Official Unity Discord | Page 1

I'm trying to make a method that will draw a line which shows where the player will land, I don't know how to do that right. The current code I have draws it wrong.
Here it is:

    void ShowTrajectory()
    {
        line.enabled = true;

        Vector3 startPos = line.transform.position; //transform.position;
        Vector3 startVel = playerTransform.forward * m.defaultSpeed + Vector3.up * (m.jumpForce / m.rb.mass / 1000); //if i won't divide this number the line goes to the sky

        Vector3[] points = new Vector3[resolution];
        points[0] = startPos;

        for (int i = 1; i < resolution; i++)
        {
            float t = i * timeStep;
            Vector3 point = startPos + startVel * t + 0.5f * Physics.gravity * t * t;

            // check for collision
            if (Physics.Raycast(points[i - 1], point - points[i - 1], out RaycastHit hit, (point - points[i - 1]).magnitude, collisionMask))
            {
                points[i] = hit.point;
                line.positionCount = i + 1;
                line.SetPositions(points);
                return;
            }

            points[i] = point;
        }

        line.positionCount = resolution;
        line.SetPositions(points);
    }
