my crawler can’t be flip and the crawler can’t die i have attack many times
this my enemy code
<code>using System.Collections; using System.Collections.Generic; using UnityEngine; public class Centipede : Enemy { [SerializeField] private float flipWaitTime; [SerializeField] private float ledgeCheckX; [SerializeField] private float ledgeCheckY; [SerializeField] private LayerMask whatIsGround; float timer; // Start is called before the first frame update protected override void Start() { base.Start(); rb.gravityScale = 12f; } protected override void Awake() { base.Awake(); } // Update is called once per frame protected override void UpdateEnemyStates() { switch (currentEnemyState) { case EnemyStates.Centipede_idle: Vector3 _ledgeCheckStart = transform.localScale.x > 0 ? new Vector3(ledgeCheckX, 0) : new Vector3(ledgeCheckX, 0); Vector2 _wallCheckDir = transform.localScale.x > 0 ? transform.right : -transform.right; if (!Physics2D.Raycast(transform.position + _ledgeCheckStart, Vector2.down, ledgeCheckY, whatIsGround) || Physics2D.Raycast(transform.position, _wallCheckDir, ledgeCheckX, whatIsGround)) { ChangeState(EnemyStates.Centipede_Flip); } if (transform.localScale.x > 0) { rb.velocity = new Vector2(speed, rb.velocity.y); } else { rb.velocity = new Vector2 (-speed, rb.velocity.y); } break; case EnemyStates.Centipede_Flip: timer = Time.deltaTime; if (timer > flipWaitTime) { timer = 0; transform.localScale = new Vector2(transform.localScale.x * -1, transform.localScale.y); ChangeState(EnemyStates.Centipede_idle); } break; } } } </code>

November 13, 2024 at 12:29 am #16311::Ok, you need to add the if statement for death in your crawler script in updateenemystates in your crawler script, add this
<code> if(health <= 0) { Death(0.05f); }</code>
Then in your main enemy script add the function for death
<code> protected virtual void Death(float _destroyTime) { Destroy(gameObject, _destroyTime); }</code>
November 13, 2024 at 2:09 am #16312November 13, 2024 at 2:43 pm #16318::your crawler state idle for ledgecheck is missing the negative ledgexcheck
Vector3 _ledgeCheckStart = transform.localScale.x > 0 ? new Vector3(ledgeCheckX, 0) : new Vector3(-ledgeCheckX, 0);
also ensure the platforms in your game have the ground tagNovember 15, 2024 at 4:56 am #16337 -
