c# - WPFパスの衝突検出？

Question

私は2つの六角形を持っています

2つの六角形間の衝突を検出する必要があります

ケース1（衝突）

ケース2（衝突）

ケース3（衝突なし）

Answer 1

FillContainsWithDetail2つのパスの交差を、それらのジオメトリの方法で取得できるはずです。

var intersectionDetail = path1.Data.FillContainsWithDetail(path2.Data);

if (intersectionDetail != IntersectionDetail.NotCalculated &&
    intersectionDetail != IntersectionDetail.Empty)
{
    // collision
}
