TileMapCollider2D+CompositeCollider2D的点击检测

使用Collider2D自带的OverlapPoint来检测点是否在范围内

且Composite的Geometry Type需要修改为Polygons

Vector2 clickPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
if (_compositeCollider.OverlapPoint(new Vector3(clickPosition.x, clickPosition.y, transform.position.z))) {
    Debug.Log("click in tileMapCollider");
}
