敌人射击之间的间隔

我正在开发一个简单的项目,作为未来项目的支柱。

我的问题是。当我从“寻找”状态移动到我的“攻击”状态时,我会检查我是否在敌人射程范围内。如果我是,它会射击我。为此,我在'if(Enemy!= none&& VSize(Location - Enemy.Location)< AttackDistance)'语句中调用了函数'FireRocket'。这完美地工作,但正如预期的那样,每秒发射一次导弹音(因为这个代码在'tick函数内)。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,计时器只在我移出敌人射程时才开始计数,但他确实开火了,但是只有在我超出其范围时才会开始计时。当我回到它的范围参数时,他停止向我射击......

问题出在“攻击”状态。

提前感谢您的帮助。

解决!这是编辑过的代码。现在,射击以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');
}
