How do I make a primitive component?

I want to make a primative component so I can get the “physics linear velocity”. At the moment the “physics linear velocity” is just returning 0.

I’m currently using an arrow componet which apparent inherits from primative component but when I try to cast to “primative component” the cast just fails. I want my whole object to be a simple box primative but can’t find any option do that.

Hi man , i dont understand completely,
In order to have an actor like a simple box,

all you need to do is go in the upperleft of the blueprint and add a component from the list, you can choose the box and the sphere component (dont use the colliders or trigger ) those are primitive.

You can do that also at Runtime using blueprint .
