how to jump in parabola.

hi ,,,

i have path like this.

i need the jump like a parabola from one tail to other. if there is one tail(i mean no need to climb) he jumps exactly what i need .but whenever the there is two tails he can jump but shape was missing(parabola),and for down also .

how can i do it

this is my code check it and give any suggestions.

void Jump () {

 Vector2    forwardAndLeftAndStright=new Vector2(1f,0);
     
     if (assignOnce == false) {
         startPoint = transform.position;

//here am giving the next tail position. targetPoint = collider_transform + forwardAndLeftAndStright;

         time = 0;
         jumpProgress = 0;

         velocityY = jumpStartVelocityY;
         height = startPoint.y;
         assignOnce = true;
     }
     
     jumpProgress = time / jumpDuration;
     
     currentPos = Vector2.Lerp (startPoint, targetPoint, jumpProgress);

     currentPos.y = height;

         height += velocityY* Time.deltaTime;


     velocityY += Time.deltaTime * Physics.gravity.y;

     time += Time.deltaTime;
     
     
     transform.position = currentPos;

//here am checking how many tails are placed before the player.if it is one then am doing this.

 if (foundHight != null) {
         if (foundHight.Length == 1) {
             forwardAndLeftAndStright = new Vector2 (2.5f, 2f);
         }
     }

//here am checking to jump down.if some thig hits then no need to jump down .if hit is none then he has to jump down.

     if (!foundHit) {
         forwardAndLeftAndStright=new Vector2(2.5f,-1f);


     }
 }
