Delay before first attack for both player and AI

[ToroidalGames]

I’ve a few lectures ahead where ai follow and attacking is introduced, and there is a bug when it comes to the very first attack/punch. For both the player and AI there Is a delay.

It seems to happen when first getting the target after moving, if I click to attack multiple enemies in range and change between them the attack speed works correctly.

But whenever I move and then click on an enemy again the initial delay bug happens.

    {
        [SerializeField] Health _targetHealth;
        [SerializeField] float _weaponRange = 2f;
        [SerializeField] float _timeBetweenAttacks = 1f;
        [SerializeField] float _weaponDamage = 5f;

        Animator _animator;
        Mover _mover;

            {

        {
            if (combatTarget == null){ return false; }

            Health targetToTest = combatTarget.GetComponent<Health>();

            return targetToTest != null && targetToTest.IsDead == false;
        }

    }

            if (_targetHealth == null || _targetHealth.IsDead) return;

            _timeSinceLastAttack += Time.deltaTime;

You’re not updating _timeSinceLastAttack if you don’t have a target, since we return if the target is invalid. Move the _timeSinceLastAttack+=Time.deltaTime to the top of the Update method.
