Gliding of Hero

I want to make my hero glide in air when the player presses particular key. How can I do that?

 

This is not tested, but it should be close.

Use Debug.log to track things in the Console. This will get it to go up and stop at a specified height. Add a time variable and track Time.unscaledTime or however you are doing time to determine when to apply a negative force, basically reversing the two situations below.

Add the compiling script to the Hero. Set the height in the script component UI.

class HeroGlide()
{

private RigidBody2D body;
private SpriteRenderer renderer;
public float height;

public float startingHeight;

private void Start()
{
body = GetComponent<RigidBody2D>():
SpriteRenderer = GetComponent<SpriteRenderer>();

startingHeight = renderer.transform.position.y;
}

private void Update/FixedUpdate()
{
if (renderer.transform.position.y < height + minHeight)
{
//apply some force upward
body.AddForce(new Vector2(0, 3); // 3 is the upward force amount, play with different values
}
else if (renderer.transform.position.y > startingHeight + height) // reached target height
{
// this code block can be used in the other if clauses, it stops the body on the y axis
Vector2 vector = body.velocity;
vector.y = 0f;
body.velocity = vector;
}

}

}
