title: Trail renderer collision detection in Unity3d
body: <p>I added the &quot;Tail Renderer&quot; component to the 2d object. Now I want to detect when the other object interacts with it make notification for this event. I have googled so much but the solutions that I have found were not good for the performance. So, the length of the trail is dynamic that is why making the collider for every vertex point of &quot;Tail Renderer&quot; is making slow the game. Isn't there any alternative way of doing it? Maybe another way not with &quot;Tail Renderer&quot;. Actually, does not matter, I need just good performance.</p>
