I have no clue, didn't think knowing how to code was a prerequesite for making a suggestion?
I'm not trying to say it's easy, I don't think any aspect of coding a game like this is. I just don't see why it wouldn't be possible. If the tracking already occurs secretly, is adding a visual indicator that much harder? The icon would last from the time the plane locks on to when it attacks. I assume once it attacks, the plane loses its track if the vehicle is outside the radius
My instinct is that making the planes track/lose the track in the first place is the hard part and that's already done. Could be totally wrong
There's brainstorming ideas and concepts and then there's implementation.
Anything that is already in the game is feasible. But been feasible doesn't mean it's gonna be easy to implement nor that it would be approved.
This is something new. The closest that came to my mind was the old IR HT beam and we know how that end up.
In this case, you are trying to apply a dynamic "debuff" which works from the Loiter plane PoV. Can you retrieve that information from the plane and use that to locate which is the target and then make it so it gets a "mark target" icon show up for as long as the plane needs to attack it and then disappear and repeat the process?
If this was feasible, that would be great. But i'm not holding any hopes on any new feature been implemented as long as it's not already done by some modder.
At the end of the day, this would only be an UI thing, cause the behaviour of the Loiter would remain the same.
