    Hi,

    I have this problem... where my Player gameObject jump and collision with another collider I see that all script code in the OnCollisionEnter2D func, runs 2 times

    How can I disable the event until the first CollisionEnter2D ends ?

    Regards

    Pablo

    OnCollisionEnter2D is called when a unique collider/collider pair first contact. You won't get two from the same collider pair until that pair have received a OnCollisionExit2D.

    Also, if you have two Collider2D on the same GameObject you'll get the callback twice; once for each collider contacting another collider.

    It's all about collider/collider pairs though so anything beyond that needs to be done via your own logic i.e. ignore the callback upon certain conditions.

    Thanks, now works fine,

    I had the same script attached to the parent gameobject, and one of children GameObject.

    You're very kind.

    Regards

    Pablo
