/facepalm im saying like it only shoots at vehicles ex: scripting the P51D Mustang and make it have a invisible beacon in it and the Anti Aircraft gun would lock on to it and shoot a heat seeking missle, but apparently even BLOCKLAND has its limits..
Of course, it's using an outdated engine.
What you're suggesting can be done, and in a simpler manner. In-fact, doing something like this is actually a very dumb idea, as then it's unable to work for other vehicles, or for every vehicle, which then requires
every single add-on maker to script this in.
A flak cannon is designed to shoot in a large radius, and quickly. It would be more efficient than having your proposal. Another solution is to use something like G-Cat's stinger missile, which locks onto a target, then follows it until boom, dead. Automatically aiming it would require a bot, and bots are horrid with vehicles. Trust me. You could, of course, turn a bot into a vehicle with Bot Events, but that's not what you want, is it, pouty-face?
Also, you could just aim in the vehicle's path, and
not directly at the vehicle, a process called "leading". I'm wondering why you need bots to automatically aim at the bloody vehicles when it would be much cooler to feel the satisfaction of shooting a plane out of the air, yourself, without any help.
