### Set Animator Controller<a id="SAC"/>
Animation Controller must be set carefully.<br>
set Transition and duration for starting & end of animtion.<br>In Script, `Animator.set~()` control state of animation.<br>Ref [This](https://www.youtube.com/watch?v=YaXcwc5Evjk&list=PLy78FINcVmjA0zDBhLuLNL1Jo6xNMMq-W&index=10) 1:40 ~ <br><br>

### Combat Basic with Player Cycle<a id="CBP"/>
Technic is same for other actions.<br>Check input, check action, and active, finish.<br>But Script is isolated.<br>Need state below

private bool gotInput;       // need for inputBotton is pushed
private bool iSAttacking;    // need for Animation & condition is Attacking now.
private bool isFirstAttack;  // need for Animation & later...

<br>

First, check input correct & set condition

private void CheckCombatInput()
{
    if (Input.GetMouseButton(0))
    {
        if (combatEnabled)
        {
            // Attempt combat
            gotInput = true;
            lastInputTime = Time.time;
        }
    }
}

<br>

Second, check state and condition updating.

private void CheckAttacks()
{
    if (gotInput)
    {
        //Perform Attack1
        if (!iSAttacking)
        {
            gotInput = false;
            iSAttacking = true;
            isFirstAttack = !isFirstAttack;
            anim.SetBool("attack1", true);
            anim.SetBool("fistAttack", isFirstAttack);
            anim.SetBool("isAttacking", iSAttacking);
        }
    }
    
    if (Time.time >= lastInputTime + inputTimer)
    {
        // Wait for new input (new attack possible)
        gotInput = false;
    }
}

<br>

Last, finish attack.<br>
Set Animtion state.

private void FinishAttack1()
{
    iSAttacking = false;
    anim.SetBool("isAttacking", iSAttacking);
    anim.SetBool("attack1", false);
}

<br><br>

### Hit Box & Player conditions<a id="HB"/>
Attack also have to check objs collider.<br>Use same technic grouding, check all objs attached.<br>Set it ~ing of animation.

private void CheckAttackHitBox()
{
    Collider2D[] detectedObjects = Physics2D.OverlapCircleAll(attackHitBoxPos.position, attackRadius, whttIsDamageable);

    foreach (Collider2D collider in detectedObjects)
    {
        collider.transform.parent.SendMessage("Damage", attackDamage);
            //Instantiate hit particle;
    }
}

<br>

And must change player's conditions, especially flip.<br>For Changing, make public function, `Enable / DisableFlip()`<br>they are called by attack animation's start and end.

public void DisableFlip()
{
    canFlip = false;
}

public void EnableFlip()
{
    canFlip = true;
}
