As you probably know, the tow which comes with version 1.00 to 1.05 of Armed Assault cannot be guided by hand. Here's a simple script, still written in OFP way as it's only a test, to 'adjust' the thing:
First thing to do is to place in the 'Initialization:' field of the unit (I just tested for the HMMWV TOW vehicle) this line:
and then save the mission in the mission editor and in the same folder place the script, saved under the name of 'fired.sqs': you should be good to go.
Please note: since the BIS TOW missile was too fast, the script provides to adjust it to the correct (almost) speed as in real life. For this reason max range is also reduced (as in real life) to 3600 meters. Don't lock the target you mean to attack, otherwise the missile will automatically steer to it (of course). For lack of time the turn rate of the missile is not controlled in any way. A further version will check for this too. I've not tested it with AI as gunners, as probably it won't work correctly. If positive feedback is encountered, we may consider releasing a simple addon (tow humvee), using the actual BIS model, but with scoped optics and of course this manual guidance script. So please check this out and report back your impressions.
