I did not give it good bullet drop so it will not work right

I take it this will work for a magnet bomber if I just twiddle the numbers? Tell it the rocket has really high mass and very low speed?
Edd 18 Nov, 2024 @ 11:55am 
oh, okay, yeah i just made them misiles
Squigee 10 Nov, 2024 @ 6:18pm 
Not sure how to get this working properly, would really love an example craft so i could visually see what im doing wrong.

@Edd
It simply creates an aimpoint based on your vectors and the rocket's ballistic properties. However, the bread is quite inaccurate. I plan on making one with actual movement equations in the relatively distant future.
Also, this uses the vectors of the base craft. You could probably rig it to work on a turret but it won't be accurate.

hey! is this ONLY for planes/helicopters? does it aim with movement? is there a way to make it work on turrets? maybe some more clarity on that could be neat
Tachyon  [author] 10 Sep, 2024 @ 7:58am 
no

does this also work for ejector mortars?

@everyone update dropped, I fixed an issue with the missile mass equation and how the breadboard finds missile speed

@nova_meteor
That sounds like a PID/control issue. This breadboard works best if you have thrust vectoring or very finely tuned PIDs with responsive control surfaces. Also, you may need to add another section to the breadboard to set the minimum altitude to extremely low (like -300) purely in strafing runs so the AI does not pitch up to compensate for low altitude. Even the slightest deviation in your aircraft's controls will cause the rockets to miss, as they do not have any independent guidance.

@von Turbo
the breadboard simply creates an aimpoint based on the variables you input, the launching of the rockets is not controlled by it
Make sure your failsafes are disabled and their controllers' firing arc enables their launching

also, to answer the first question, missiles in FTD do not weathercock so it may look like they level but they are really not
von Turbo 9 Sep, 2024 @ 4:00pm 
I've had the following issues:
1. missiles level into horizontal flight after launch (launch aircraft in shallow dive during launch)
2. missiles launch much later than LWC enables Missile Controller. (LWC set to 900m, missiles launch at half that)
As far as I know, all variables seem correct (missile drag, Center Mass, etc.)

Tachyon should probably upload am example plane with this bb
nova_meteor 9 Sep, 2024 @ 11:15am 
@Tachyon i have it linked i figured that out and got it to stop crashing into the water now the problem is it not being able to aim itself at the enemy and make proper attack runs (it is circling the target not really aiming itself properly) possibly i need a more maneuverable plane, i probably need to do more testing.

@von Turbo
They need no guidance whatsoever, just a thruster and fuel tank. The rest can be payload.
Also, thank you! Breadboards can be very fun once you get the hang of how they work.

@nova-meteor
One of two things could be going wrong-
You could not have an enemy target, if so then the breadboard will output NaN and the vehicle will try to go to 0, 0, 0, which is probably why it is going into the water.
Or you could not have the breadboard behavior correctly linked and the vehicle is going to its default position: 0, 0, 0. The breadboard behavior's filter name is "attack" (case sensitive), though you can always change that with the breadboard behavior component located at the bottom right corner of the board.
von Turbo 9 Sep, 2024 @ 10:55am 
Does the missile need any guidance components, such as "one-turn" or "APN"?
Im just getting into breadboarding - this is inspirational.
nova_meteor 9 Sep, 2024 @ 7:12am 
also what did you do with your AI is it bread board link behavior? if so my plane just slams into the water when i use it.

diameter can be found with the CIWS controller, 250mm small, 500mm medium, 1000mm large, 2000mm huge
nova_meteor 8 Sep, 2024 @ 4:41pm 
with the equation for rocket mass it would be nice if missile diameter was listed for small medium large and huge missiles also i presume the diameter is millimeters and the weight in kilograms? if so i keep getting insanely low numbers for an eight segment medium i am getting .035
Tachyon  [author] 7 Sep, 2024 @ 8:22pm 
they are missiles without any guidance components or fins. thruster -> fuel tank -> tons of payload
Abyssi Lolligo 7 Sep, 2024 @ 7:15pm 
Are these rockets like missiles or like ai controlled suicide 'rockets'
Tachyon  [author] 7 Sep, 2024 @ 7:06pm 
@Tynaiden I've done that before also... it falls short against moving targets or small targets though
Tachyon  [author] 7 Sep, 2024 @ 7:05pm 
@Lincrono fully unguided rockets allow for much more payload space, all you need is a thruster and fuel tank and the rest is payload 😉
Tynaiden 7 Sep, 2024 @ 6:13pm 
Thank you!
I've been using two-stage missiles with the first stage set to 'fired direction' with no targeting at an upward angle then having the smaller missiles launch with one-direction guidance to approximate a ballistic style system.
Lincrono 7 Sep, 2024 @ 4:56pm 
since there are rocket lovers here. One-Turn. *fantastic* for simple rocket craft as it keeps the fins flying straight, does make it impossible to make cool lobbing shots though.
Tachyon  [author] 7 Sep, 2024 @ 8:08am 
quick note- rockets behave very similarly to CRAMs, so if the enemy moves sporadically then they will probably miss
