How to force a value stored in variable?

hello,

thank you for your answer! here some pictures to explain what i'm trying to do: 1-the first triggered zone is very big (enter zone) to avoid (i think) to collide again. It sets canClimb to 1 2- the second is another triggered zone to align the hand with the edge collider 3- if the hand AND can climb is true, then he can climb

 }

}

when i press jump, i can see in the log that canJump switch to "false" than when i reale the space key it goes back immediatly to "TRUE".

I'm sure it has something to do with passing the variable, public variable...

I think when you are pressing Jump, your velocity is greater than 0, so you Unity will execute this code:

    if(velocity.y>0)
              {
                  rb.constraints &= ~RigidbodyConstraints2D.FreezePositionX;//| unfreeze position
                  canClimb = false;
                  print("FROM playerMotorV3.cs : "+canClimb);
                  rb.gravityScale = 2;
                  print("FROM playerMotorV3.cs : jumpFromLiana");
                  rb.AddForce(new Vector2(velocity.x, velocity.y) * jumpSpeedLiana * Time.deltaTime, ForceMode2D.Impulse);//permet de sauter
              }

Good, but after it, you don't change your canClimb back to true never. You have to exit your current trigger, and enter it back for triggering it, and then you will change your canClimb from OnTriggerEnter.

I think you can add some new bool to your playerMotorV3 script, like private bool m_jumping;.
And then make it true if velocity.y>0 , and make false if it is not. And before you can climb you have to check two bools canClimb and !m_jumping (m_jumping == false). So you will check if i can climb (it is meaning that you are on trigger zone) and if i am not jumping.

P.S this can be wrong, because i am sleepy and tired today:/

P.S #2... You can cut it short and try to add grounded to your this line:

    if (canClimb && grounded) // HERE // HERE// HERE // HERE // HERE
         {
             rb.gravityScale = 0;//to set no gravity if the player touch the liana
                                 // print("FROM playerMotorV3 : " + parentPlayer[1]);

So you will check if you are grounded and canClimb , then only allow to climb. And you have to remove canClimb = false; from if(velocity.y>0).
