Cannot get traces to return hits

I have got a problem with tracing in blueprint in that whenever I trace something I get no results whatsoever.

In the example, I have set up a staticmeshactor to do a spheretrace. No matter what objects I set for detection, it won’t return a true. I have double checked the actor’s object responses and it has been set to BlockAll, so as far as I know, I should at least get it to return a true on itself. I have also tried a trace by channel, but it’s the exact same result. Nothing.

Since I am trying to do the behavior tree tutorial, I really need these traces to work. At the moment, I cannot get that tutorial to work either since, again, no matter what I do the traces simply return nothing.

1: is your input array of object types to detect populated.

2: On the end location add a small vector of 0,0,15 I think the sphere traces works by moving a sphere for X radius along a line from start > end, therefore your end needs to be different from the start point.

Also make sure if your detecting all object types to ignore yourself.

It was the second. I had properly taken care of 1 (to the point of throwing in all possible objects at one point). I had no idea that the positions needed to be different. I thought that as long as the Radius was not 0, I would be good to go.
