i was able to put a script together through research on the movement and jumping of a rigidbody...but i noticed that anytime i jump up and i try to come down, i go through the stationary platform beneath me...the platform moves with my rigidbody and i want my rigidbody to stand on my stationary platform anytime it comes down after jumping up...here is my script

pragma strict

var playerSpeed: float; var projectilePrefab : GameObject; private var speed : float = 0.5f; //private var JumpHeight : int = 30.0; var JumpSpeed : float = 25.0f; var JumpStrength : float = 0.3; var JumpDecay : float = 0.01; var Jumped : boolean = false;

function Jump() { animation.Play("timi"); rigidbody.AddForce(Vector3.up *JumpSpeed );

 }
 
 

function Update() {

     if (Input.GetKey(KeyCode.RightArrow))
         this.transform.position += Vector3.right * speed;
     if (Input.GetKey(KeyCode.LeftArrow))
         this.transform.position += Vector3.left * speed;
    if (this.Jumped){

this.transform.position.y += this.JumpStrength - this.JumpDecay;

this.JumpDecay += 0.009; }

   if(Input.GetKeyDown(KeyCode.UpArrow)){
   this.Jumped = true;
  Jump();
  }
 

transform.position.x = Mathf.Clamp(transform.position.x, -545, -435);

//to shoot bullets using the jump key
if(Input.GetButtonDown("Jump")){ Instantiate(projectilePrefab, transform.position, Quaternion.identity); }

}
