C# SAT中的碰撞仅在两个方向上工作

我试图通过XNA中的SAT解决碰撞问题，但它只在底部和右侧两个方向起作用。我认为这个问题是由于轴有负分量时，重叠未通过长度检查造成的

冲突解决方法：

public Vector2 Collides(Rect other, float selfr, float otherr)
        {
            Vector2 minTranslationVector = new Vector2(Single.PositiveInfinity, Single.PositiveInfinity);
            foreach (Vector2 v in GetRotatedNormals(selfr))
            {
                float[] minMaxA = ProjectRotatedAlongAxis(selfr, v);
                float[] minMaxB = other.ProjectRotatedAlongAxis(otherr, v);
                float minA = minMaxA[0];
                float maxA = minMaxA[1];
                float minB = minMaxB[0];
                float maxB = minMaxB[1];
                if (!(maxA > minB && maxB > minA))
                    return new Vector2(0, 0);
                float overlap = Math.Min(maxA - minB, maxB - minA);
                if (Math.Pow(overlap, 2) < minTranslationVector.LengthSquared())
                {
                    minTranslationVector = v * overlap;

                }
            }
            foreach (Vector2 v in other.GetRotatedNormals(otherr))
            {
                float[] minMaxA = ProjectRotatedAlongAxis(selfr, v);
                float[] minMaxB = other.ProjectRotatedAlongAxis(otherr, v);
                float minA = minMaxA[0];
                float maxA = minMaxA[1];
                float minB = minMaxB[0];
                float maxB = minMaxB[1];
                if (!(maxA > minB && maxB > minA))
                    return new Vector2(0, 0);
                float overlap = Math.Min(maxA - minB, maxB - minA);

                if (Math.Pow(overlap, 2) < minTranslationVector.LengthSquared())
                {
                    minTranslationVector = v * overlap;

                }
            }
            return minTranslationVector;
        }

在我们帮助您之前，您需要解释变量的含义。在2D中使用旋转矩形正确吗？

foreach (GameObject obj in room.Objects)
            {
                if (!obj.HasCollisions)
                    continue;
                Rect playerRect = new Rect(BoundingBox);
                Vector2 minTranslationVector = playerRect.Collides(new Rect(obj.BoundingBox), 0, 0);
                playerRect.topLeft += minTranslationVector;

                toDraw += playerRect.isNegative;

                Position = playerRect.topLeft;
                BoundingBox = playerRect.ToRectangle();
            }
