c# – for循环始终只执行ONCE

简要信息图片,我的代码做了什么：

这是我的代码：

private void CheckObjectAttackPoints(Point AttackPoint){
    Point ObjectAttackPoint = AttackPoint;
    ObjectAttackPoint.X -= 1;
    int count=0; //This variable for reading how many tiles are false
    //Check tiles active and ObjectAttackPoint is exist in List
    for (int i=0; i < 1;i++) {
        if (GameManager.AllPoints.Contains (ObjectAttackPoint)) {
            if (!GameManager.TileColliders [ObjectAttackPoint.X, ObjectAttackPoint.Y].activeSelf) {
                count++;
                ObjectAttackPoints [i] = ObjectAttackPoint;
                Debug.Log (ObjectAttackPoints [i].X +", " + ObjectAttackPoints [i].Y);
            }
        }
        if (i == 1) {
            break;
        }
        ObjectAttackPoint.X += 2;
    }

    if (count > 0) {
        Debug.Log ("Object can attack " + count + " points");
    }

}

因此,此方法需要已经具有AttackPoint.Y-1值的AttackPoint,我们只需要检查List中是否存在AttackPoint.X并检查此时对象是否处于活动状态.在方法启动时,AttackPoint.X将其值减1.

我的问题是,即使两个图块不活动,控制台也只返回一个点(示例图像：0,0和0,2图块不活动,控制台仅返回count = 1并且使用点0,0图块),这意味着方法只检查一个tile并且我的代码有错误,但我无法理解它在哪里.
有人能帮我吗？

解决方法:

你的for循环总是完全执行ONCE,你的方法的代码等同于：

private void CheckObjectAttackPoints(Point AttackPoint) {
    Point ObjectAttackPoint = AttackPoint;
    ObjectAttackPoint.X -= 1;
    int count = 0; //This variable for reading how many tiles are false
                   //Check tiles active and ObjectAttackPoint is exist in List
    if (GameManager.AllPoints.Contains(ObjectAttackPoint)) {
        if (!GameManager.TileColliders[ObjectAttackPoint.X, ObjectAttackPoint.Y].activeSelf) {
            count++;
            ObjectAttackPoints[0] = ObjectAttackPoint;
            Debug.Log(ObjectAttackPoints[0].X + ", " + ObjectAttackPoints[0].Y);
        }
    }
    ObjectAttackPoint.X += 2;

    if (count > 0) {
        Debug.Log("Object can attack " + count + " points");
    }
}

如果要循环遍历ObjectAttackPoint的所有元素,则应使用

如果它是一个List：

for (int i=0; i < ObjectAttackPoint.Count;i++)

如果它是一个数组：

for (int i=0; i < ObjectAttackPoint.Length;i++)

编辑：当i == 1时,休息条件的用途是什么？即使你扩展了for循环,if会在两个循环之后完全打破循环(即在i == 0和i == 1之后执行它).你应该更深入地解释什么是ObjectAttackPoints.
