Bouncy platforms/spring jump?

I'm creating a fps set in space. The simulated forest environment is rather large in scale. I was planning on creating separate platforms to the terrain itself (from Cube) to act as something that if jumped onto it would throw you high up into the air to reach for example high cliff edges.

An idea like this is possible?

Much thanks.

Here's a simple solution.

var bounceForce : float = 10;

function OnCollisionEnter(hit : Collision)
{
  if (hit.gameObject.tag == "Player")
  {
    hit.rigidbody.AddForce(bounceForce * transform.up, ForceMode.VelocityChange); 
  }
}

This code goes on the platform. The way it works is that the force is being applied to the platform but since the platform doesn't actually move, the force is transferred to the player giving it that bounce effect. I hope that makes sense. There's a bit too much to break down so if you'd like to know what those fancy words are saying you could reference the manual. I hope this helps at all.

In the code above the force is not applied to the platform but to the “hit” object, which is the object that collided with the platform, so there is no magic as such.

can you help me , I am having my ball as the gameobject and I need to bounce everytime it hits a platform. thanks I am a beginner.

Add physics material,Add physics material and add bounce
