See what you mean. Thanks I finally understand the Xbox controller some confusion for me, between "trigger" and "bumper" . With blowing up those containers, is there anything special I need to do there. I have tried varying the distance and shooting the sh*t out of them, in the circle, but they don't blow up.
Assuming you are still referring to the tutorial I show how to do this at the 12:40 point in my video (I'll attach it below at the right time stamp).
You need to first of all target the thing you want to shoot - you should see the Guillemets (angle-brackets / chevrons)
* appear around it in the HUD and in the lower left you can see it show up in your target hologram.
As you shoot it you can see the hull health of the capacitor reduce beneath the target hologram - it then blows up at 0% and the hologram clears to an exclamation mark (ecphoneme).
The same targeting is used for anything you need to interact with (shoot, scan or collect).
You can hit things without targeting them - as I did with the second capacitor - so I don't know why you were unable to do so. In combat when using gimballed weapons it is often useful to "untarget" your enemy if they are chaffing - by doing so you are effectively using the weapons as fixed ones and thus defeat the chaffing.
* There is a bug that causes these not to show sometimes - I don't know of a work-round for this years-old bug.
