Offsetting no matter what vector

I’m not very good with CFrames and positions, so how can I offset a certain amount no matter what vector I’m in. As you can see from the video I’m offsetting the position by 8 studs in the X axis and obviously it doesn’t offset correctly in the Z axis.

But thats only moving it forward, I want to move it to the left and the right.

edit: nvm i’m chilling
