A strange problem about line trace

I face a strange problem. It has cost much time. when I set " world Dynamic ", I can see the line trace. But when I set " InteractiveObject " which is customed by myself, the line trace disappeared.

world dynamic



InteractiveObject

I think it’s probably the collision settings of the object you’re trying to hit. What is it blocking etc?..

Sorry, I do not understand, can you tell me more?

Your object, or component, which has collision type ‘interactive object’ has to block the line trace. Is it set to block?

yeah, I have set ‘interactive object’.

But the strange thing is why the line trace disappeares and then it can not detect any thing.
