No luck with the rockets so far - tried changing the Typhoon rocket data in the .tweak file to match that in the AIX P-51, including the MultiFireArmTargetComp bit, but they still don't actually fire the rockets. However, they don't seem to use guns on ground targets anymore despite the guns not being disabled - which suggests that they're trying to fire rockets but for some reason can't.
Saw your post in the other thread re. contacting Clivewil - hope he can help out with this! I think I've given up on this problem for the time being.
I have had more luck with the Stuka siren, I've managed to integrate the AIX code into the FH2 Stuka, but currently the siren only activates when in a very steep dive. I'll see if I can lower the activation speed.
Anyway, I'll be releasing another beta version some time this week. It's not really polished enough for a non-beta release, but I haven't had that much time lately to work on or playtest it so I'd rather get a playable version out now than wait weeks more to get everything working correctly.
I've made numerous improvements + fixes since the last beta, but there are still some annoying bugs like bots not firing at gunner positions, and the CTD on Purple Heart Lane.
