OK, I know this is an old thread, but I absolutely have to post here and say THANK YOU.
I was beginning to have real trouble in XTC (the X-Tended Mod for Terran Conflict, which is now in its first public release) because ALL of the M7 class frontal weapons are now flagged as "chargeable." This means if you hold down the boresight fire key, as I am used to doing, they don't fire a nice stream of projectiles, but rather "charge up" a shot... and usually miss.
This script was recommended to me simply to solve that issue, and it did... but it has done MUCH MORE for my game than that! I use a mouse + keyboard and, like Jaga said above, this script is UTTERLY INDISPENSABLE for anyone who uses that control setup.
Previously, I could only hit an enemy if my targeting reticule was placed over the leading "pip" and that meant that I could only shoot at my enemies while basically flying a collision course toward them!
Now, with this life-changing script, I can actually steer my million-ton frigate AWAY from a collision, and also strafe and roll, all while pouring hot death right into his bridge.
Is it fair? In my opinion, it perfectly simulates having a separate crew member firing the guns while the captain is busy with the helm... in other words, completely realistic. Can you imagine if the navy required the captain of a boat to aim and fire the guns, WHILE steering the ship? Ridiculous!
In short, this is one of those things that has the feeling of "ah, this should have been in the game all along." Gazz, I know I've said it before, but you're a genius. I was ready to quit playing this game, and your tiny little auto-aim script has made me excited to play it all over again. I wish I had known about this back when you wrote it... I'd have been using it the whole time.
You're the best. Thank you.
P.S. No compatibility issues with XTC that I've found, but I'm not really knowledgeable about scripting. Hopefully it won't do any damage down the road.
I don't think I could go back to playing without it (at least not in an M7 with frontal guns).
EDIT - one last thought. The people who said the script wasn't switching on properly, or switching on, firing a shot or two, and toggling back off... I think I know why. At least, I figured out why it was doing it to me. I was holding down the left mouse button at the same time I hit the hotkey, and the game really doesn't like that. Any key you press while the button is held down seems to rapid-fire. Try it: with the left mouse button held down, try hitting any key, like "T" to switch off the little targeting brackets while they're flashing, and you'll hear several bleeps happen very quickly (and the brackets will still be flashing, because you've just pressed "T" more than once).
So just make sure you're not pressing any other keys or buttons at the same time (i.e. not "mouse steering") and it should work fine. It does for me, anyway.
Oh, and happy new year. There, I'm done.
