Hi again, thanks for the welcome!
I got it working with line trace, and yeah that “needle” is in 3D form not UI. One thing i can’t get is sound it plays but it doesn’t stop. Here is the Screenshot, i probably didn’t do something right, but i’m new in Game Development and i have spend so much time on getting this system to “work” 
And i love every thing about Unreal and Epic, You guys really try to make everything simple and help people
