我正在做一个简单的项目，它将成为未来项目的支柱。

我的问题是。当我从“寻找”状态转移到“攻击”状态时，我会检查我是否在敌人的火力范围内。如果我是，它会朝我开枪。为此，我在“if(Enemy != none && VSize(Location - Enemy.Location) < AttackDistance)”语句中调用了函数“FireRocket”。这工作得很好，但正如预期的那样，每秒会发射一个音调的导弹（因为这个代码在一个 'tick 函数中）。为了避免这种情况，我尝试使用 SetTimer (SetTimer(FireInterval, true, 'FireRocket');) 这就是我的问题出现的时候。

现在，计时器仅在我移出敌人的射程并且他确实开火时才开始计数，但同样，只有当我在其射程之外时才开始计时。当我回到它的射程参数时，他停止向我开火……

问题出在“正在攻击”状态。

预先感谢您的帮助。

解决了！这是编辑后的代码。现在以 1 秒的间隔正确射击。

state Attacking
{
    function Tick(float Deltatime)
    {
        //HasFired = true;

        if(Enemy == none)
        {
            GetEnemy();
        }

        if(Enemy != none && VSize(Location - Enemy.Location) < AttackDistance)
        {
            ShootRocket();
        }
        if(VSize(Location - Enemy.Location) > AttackDistance)
        {
            GoToState('Seeking');
        }
    }
}

/////////////////////////
function ShootRocket()
{
    local UTProj_Rocket MyRocket;

    if(Enemy != none && VSize(Location - Enemy.Location) < AttackDistance && HasFired == false)
    {
        `log("BOOM!");

        MyRocket = spawn(class'UTProj_Rocket', self,, Location);
        MyRocket.Init(normal(Enemy.Location - Location));

        MyMesh.SetMaterial(0, AttackingMat);
        SetTimer(1, false, 'EndAttack');

       HasFired = true;

        if(HasFired == true)
        {
            SetTimer(FireInterval, false, 'IsAttacking');
        }
    }
}

function IsAttacking()
{
    HasFired = false;
    GoToState('Attacking');
}
