What does bChecker used for?

I was doing research about visual scripting in UE4. I came across this bchecker that is under variables section under my blueprint. What does this mean?

Hey ,

Could you show us a screenshot of your Blueprint? What kind of Blueprint is this appearing in?

Here is blueprint.

This is not my own script, I was doing research on Unreal 4 for a teacher that I have.

Hey ,

It looks like a custom variable. If this isn’t a Blueprint you made, it’s likely that its creator made a Boolean variable and then didn’t use it. If you click on it, you can see more about it in Details panel below. You can create new variables using +V button in My Blueprint panel, and first type that comes up is usually a Boolean.

Hope that helps. Let me know if you have any other questions!
