游戏地图中的隐形标记-Unity 2D游戏

Question

How can I place specific points on my 2D tile map that are invisible and do not obstruct any movement in the game, and when the player interacts with this it fires some code. Any help would be great, thanks!

Let me know if more description needed

Answer 1

You probably want to use a BoxCollider2D as a trigger (ie set the IsTrigger flag to true). You can override the OnTriggerEnter2d method to fire off your code when something enters the bounds of the collider.

Setting the IsTrigger flag will cause the collider to NOT block any actors. It will simply trigger the events as the collider is entered / touched / exited etc.
