is there a way to make my Jump script only jump once?

Question

this is my script[SerializeField] private float _Speed = 1.0f; private bool _IsGrounded = true; [SerializeField] private float _jumpForce = 2.0f; public Vector3 Jump;

 Rigidbody RB;

 private void Start()
 {
     transform.Translate(new Vector3(-22.80f, 1f, -24.17f));
     RB = GetComponent<Rigidbody>();
     Jump = new Vector3(0.0f, 2.0f, 0.0f);
 }

 private void OnCollisionStay()
 {
     _IsGrounded = true;
 }

 void Update()
 {
     PlayerMovement();
 }

 void PlayerMovement()
 {
     float hor = Input.GetAxis("Horizontal");
     float ver = Input.GetAxis("Vertical");
     Vector3 PlayerMovement = new Vector3(hor, 0f, ver) * _Speed * Time.deltaTime;
     transform.Translate(PlayerMovement, Space.Self);
    
     if (Input.GetKeyDown(KeyCode.Space) && _IsGrounded)
     {
         transform.Translate(Vector3.up * _jumpForce * Time.deltaTime);
         RB.AddForce( Jump * _jumpForce, ForceMode.Impulse);
         _IsGrounded = false;
     }


 }

}

Well you need to define _IsGrounded correctly. The way to do this is by creating an empty GO underneath the feet of your player and use Physics.CheckSphere to create a radius around your empty GO. Then you can say _IsGrounded = Physics.CheckSphere(Groundcheck, 0.4f, Ground); where Groundcheck is the empty GO under the player, 0.4f is the radius, and Ground is a public LayerMask that is the layer assigned to all walkable/jumpable ground. Then, _IsGrounded will be true when this sphere is colliding with an object with the layer ground, and will be false when not. This will ensure that once youve jumped, _IsGrounded is false and therefore you can't jump again. @hamanieye
