A TV guided bomb you can fly around! Or rather, glide with!
I was getting sick of tinkering with Lawn Mower and UMOR-N guided bombs, and also wanted to build a period appropriate fictional guided bomb for my AG Fugitive attack jet, and decided to build something that resembles AGM-62 Walleye of the real world. It was going to be a reskin of UMOR-N at first, but I realized during a build session that Gyro can steer these bombs independent of the mothership aircraft, which allowed me to build an actual manually (& automatically) guided glide bomb. I assume plenty of people bave made this kind of thing already, but I'm very happy that I could make one from scratch myself. Feel free to use this on your build (I'd appriciate credit if you're going to upload the plane with this!).
User's Manual
1000lbs TV-guided bomb
W&W AGM-43 "Mike"
*Remove flight computer and save as sub assembly.
*Edit detacher and gyro setting for each if you want to dupe them and drop/control them separately.
<Automatic guidance mode>
Range: 9km
1. Lock on to target
2. Drop (fire weapon button)
*AG6 or 7 for limited manual override.
<Manual guidance mode>
Range +9km
1. Switch to respective camera
2. Identify target
3. Drop bomb (AG6 or AG7)
*Do not deactivate AG until bomb hits something
4. Guide bomb to target
Yaw control=VTOL
Pitch control=Trim
(If you are in AG Fugitive, use the aircraft's gyro and trim lock for aircraft stabilization)

Pls prefix It i dont know how to make airplane
@Goofygg5
That would be cool!
Idk if you're on or not but I can give you a camrea guidance code it's pretty simple
@OrderlyHippo
Nah it's fine, figured that was a brain fart of sort, lol Besides, the example really did help me improve my understanding of it. I hD read PID page of Snowflake's Funky Trees Guide many times before, but I just couldn't get it. I think that was due to the lack of practical example on the page.
I'll re-read your comment later. Check this post in the mean time, it might interest you.

You may be able to use rexizon's PQ-14 FT (link in the post comments) for something like a loitering missile- no nvm, I might be thinking of someone else
@Kendog84 I explained PID so incorrectly. Sorry lol just fixed it
@OrderlyHippo
Thanks, these examples (including the other one on gyro page) helped me understand it a lot. Still don't know what the heck is going on with it, but I now have a vague picture. What I made so far is really weird though, like (I think) it's supposed to keep the plane's pitch angle to 0, but it tries to flip 180 degrees and fly upside down (if it's still flying). Still got a long way to go, lol
I came up with a rotator that stores current altitude using smooth function though (will upload the whole thing later), so I can at least achieve similar function with something I know better. Code will probably be a lot more simple and efficient once I understand how to make PID FT in the game though.
@Kendog84 That might give you a headache because of how much code it has lol. Start small and try making a plane fly straight
PID(
target
,
current
,
I think this value just multiplies your output value. It scales it all up or down otherwise known as PROPORTION.
,
this value says how much fluctuation can happen until any real adjustments are made basically a "room for error" value called INTEGRAL
,
how quickly over time it adjusts to meet target from current value which has the most effect when your "room for error" has run out called DERIVATIVE
)
PID(0, PitchAngle, 1,1,1) I think would work.
* Changing 0 to be Trim*90 will make it try to pitch the plane up or down up to 90 degrees wherever you move Trim slider.
* If you get a feedback loop and it pitches like nuts, make final DERIVATIVE value, 1, into 0.5 or some smaller amount. Usually it won’t need to be changed much.
* After that, I think you could even change PitchAngle to be PitchAngle+RollAngle and subtract RollAngle on the other wing.
It’s hard to find to a useful PID example so I hope this is good
@OrderlyHippo
I might try that at some point, I still don't quite get how it works though :( (I've read Snowflake's guide on it, and read some of wikipedia article of PID controller)
I should probably study your camera-steering missile's FT closely in fact
If you want to use the camera look for the bomb’s flight you should us PID controllers. Snowflake’s funky trees guide is helpful for that
Your welcome 😃😃
@VIPGOD27TH
Thanks!
Cool
