Let's see I'm designing a 2D game with unity, but I'm looking for a solution to make a method in my main character's script where when entering a collider2D (with a Trigger2D) placed in his vertical stair sprite, he can activate your climb animation and can move upwards, canceling gravity and leaving the collider to activate it again
After investigating and with the help of a teacher we managed to get the character up the stairs and move on it:
When entering and leaving the stairs:
private void OnTriggerEnter2D(Collider2D collider2D)
{
if (collider2D.tag == "Player")
{
collider2D.GetComponent<PlayerController>().MoveStair();
}
}
private void OnTriggerExit2D(Collider2D collider2D)
{
if (collider2D.tag == "Player")
{
collider2D.GetComponent<PlayerController>().ExitStair();
}
}
In the character controller:
[SerializeField]
private bool _isClimbing = false;
public void MoveStair()
{
_isClimbing = true;
_rigidBody2D.gravityScale = 0f;
_animator.SetTrigger("Climb");
Debug.Log("Entro en una escalera");
}
public void ExitStair()
{
_isClimbing = false;
_rigidBody2D.gravityScale = 1f;
_animator.SetTrigger("ExitClimb");
Debug.Log("Salio de una escalera");
}
Note: when we finished climbing the ladder the character did not manage to get down, for a boxcollider theme (using 2D platform effector).
