Bounce into the air

Question

Hi guys

I'm working on a 2D game, and I need a projectile prefab bounce/flap/jump in the middle of the air after the player press the mouse. In this case, while it moves along the X-axis, it is necessary to apply a force inversely proportional to the projectile's angular direction on the Y-axis in relation to its own x-axis line (only when it has a negative angle in relation to the horizontal line). The new velocity should be minimally lower than the previous one, divided by the percentage of "SlowDownFactor." Something like that: alt text

I'm new to Unity, so I don't know exactly which commands to use to apply this inverse force, I've already taken a good look at the documentation, but I haven't been very successful. The code I have so far:

 {
     [Range( 0, 1 )]
     public float SlowDownFactor = 1;
     private Rigidbody2D red_rigidbody;
 
 
     public void ExecuteAirSpecial()
     {
         red_rigidbody = GetComponent<Rigidbody2D>();
         Vector3 redAng;
         red_rigidbody.AddRelativeForce(Vector3.Angle(redAng.y, -redAng.y) * SlowDownFactor);
     }
 }

 [Range( 0, 1 )]
      public float SlowDownFactor = 1;
      private Rigidbody2D red_rigidbody;
  
  
      public void ExecuteAirSpecial()
      {
          red_rigidbody = GetComponent<Rigidbody2D>();
     
          red_rigidbody.AddRelativeForce(Vector2.Perpedicular(transform.forward) * SlowDownFactor);
      }

try this, it adds a force to the direction perpdicular to the objects forward (normal in your image)

Hi there, thanks for your awsare. I end up going like that:

 public class AirSpecialBounce : $$anonymous$$onoBehaviour, IAirSpecial
 {
     [Range( 0, 1 )]
     public float SlowDownFactor = 1;
     private Rigidbody2D red_rigidbody;
 
 
     public void ExecuteAirSpecial()
     {
         red_rigidbody = GetComponent<Rigidbody2D>();
         Vector2 red_velocity = red_rigidbody.velocity;
         if (red_velocity.y < 0)
         {
             red_rigidbody.AddForce(new Vector2(0, -red_velocity.y) / (SlowDownFactor / 100));
         }
     }
 }
