Unity 2D line collider

Question

I try to do the following: I have a point A at -4x-4y and a point B at 4x 0y. I want to make a colliding line from position A to position B.

I tried to do it with a linerenderer but I can't get the line to collide with my other 2d objects.

My other tought was to calculate the center of the points and the rotation and do it with a box collider but that seems to be really complicated and hacky.

Is there a simple way to achieve this?

Thanks in advance

Answer 1

您可以使用PolygonCollider2D ，它会自动为精灵创建碰撞器，如果您对结果不满意，可以通过单击检查器中的编辑碰撞器来编辑它，或者使用Unity的API 。

Answer 2

I think you must have a Rigidbody2D attached with your other 2D object. Then this will work 100%. You can use any collider it doesn't matter.
