I'm talking about how you are ACTUALLY supposed to code it. Not the general idea behind it. Without requiring "hack" type solutions to make it work.
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
