@j20m I'm going to assume you want a sub assembly version of the missile to mount on your own plane
Unfortunatly making it a stand alone sub assembly is not going to make mounting the missile on your plane easier. Please reference my other missile where I have created detailed installation and set-up instructions (such as my Aim-9P).
I can understand Chinese but I would prefer to communicate in english.
@dekanii Hi, would you mind me taking a look at the missile system? I'm assuming you are trying to implement a SACLOS Shillaili and I would be happy to help you make it work.
@Graingy Ik and I absolutely do not plan to give up making simpleplanes not so simple. I am interested in seeing how my usual ft missiles will stack up against the new ones though.
@llFLMTll I can put Tomahawks in my long long list of future projects, sure
I may wait till Simpleplanes2 comes out to at least publish a guide of sorts on how to make missiles. I'll look into starting the guide probably sometime soon.
So proportional navigation depends on keeping the angular acceleration of the missiles flight path proportional to the angular rate of the line of sight angle of the target, and thus the missile ideally only takes acceleration commands. The trouble I had for the longest time was how do I make a missile hold a certain angle (in this case pitch angle) using acceleration commands.
As for the science of lofting it is exactly as I described in the description. Let me know what else I can clarify.
@Warwolf182 basically you are going to go to your plane and make the variable menu have the exact same things as the variable menu of the pod when you first download it. So copy the name (left side of the variable box) and the expression (right side of the box) from the pod, then go to your plane, and copy in the name and the expression.
Simpleplanes gives you the very very basic to work with and there’s not a lot of shortcuts to working from only the foundation. Take a look at my codes (I highly suggest any missile but this one) and see if you can make sense of it and implement it on your own missile.
@Object775blyat You have to open Overload on the part and its gonna be part of the engine's XML properties. You add it to the same page as the power multiplier and exhaust color override.
@Object775blyat In the engine properties your gonna add a new property called "throttleResponse" and set that to whatever. The higher the number the faster the engine spools up.
@QuesoAirlines So the reason it did that is not necessarily because you clicked it, but you double clicked to open the modify menu. The degree range on the rotator is precisely 1 degrees, and if you open the default part editor (the menu that comes on on the left side of the screen) the game won't be able to process that I only want it to turn 1 degree and so it makes the range 0 degrees, which is free spin.
To properly fix that you should've opened fine tuner and change the range back to 1 degree and speed back to 1.
@kismit Well done on the success of your build. We may have talked about this before already but my offer to mount funky trees weapons to your build instead of default missiles still stands; you know where to find me.
@CACHA That highly depends on how the rest of your plane is built. You could potentially turn whatever you want to measure onto it's butt and measure the drag force when the entire belly of the plane is headed into the wing (aoa of 90 degrees) and the correlation of aoa and drag force should be roughly linear.
To answer your question better,
Funky Trees is essentially a coding language unique to SimplePlanes and essential to programming your plane to do more than the bare, default, minimum.
A Funky Trees MIssile is essentially re-inventing the wheel in terms of practicality, since the in game default missiles are a lot more easily customizable, consistent, and easy to use. However, there is joy for the small number of us to take advantage of the game's physics engine to test our engineering abilities.
@Magma1358 Hi,
Essentially, there's two parts in creating a funky trees missile: making a stable and good performing missile, and then making an auto pilot that tracks a target. I would recommend starting with the first task, then researching how to do the latter. Please see some of my other posts where I explain more in depth in the comments.
@SuperSuperTheSylph Good work on the missile, however I have a couple feedback based on my own experience with FT missile
1. The symmetrical airfoil wings stall past 13 degrees of aoa, so there's usually no point in deflecting the fins past like 10 degrees; this will almost always give you the best maneuverability
2. The guidance is very rudimentary and tbh very inaccurate. I would recommend you to look into the kinematic equation in radial coordinates, aka what automatic turrets also use for lead/aim. If you want to take it one step further, I recommend you to look up proportional guidance in the context of missile guidance design.
That being said, this is a big step for you and I remember taking steps like these 2 years ago.
@Quercon and yes i have considered using coordinate transfers but those are extremely tedious to code and is simply not worth it for this type of build. Perhaps it would be worth it for future ballistic missile builds though.
@Quercon PID is a very simple and flexible tool and how to calibrate it depends on your understanding of what the I and D term does. The I term is used if you have consistent undershoot that can not be corrected with P over time, and D is used for dampening oscillations and preventing overshoots. What i used in this missile specifically is called proportional guidance, and it guides by controlling the angular acceleration of the missile , and so it oscillates a lot, thus i have a D term. Feel free to go into the code and mess with it to see what i’m talking abt.
@waylaymythz someone already beat me to it. I think someone made an ultimate countermeasure to all missiles in game and it was posted like a month ago. It works well against my missiles to and I recommend u checking it out.
@UltravioletBlood a lot of trial and error. Make sure both the bomb and the fuselage section you intend for it to smash into have collision enabled, and it's just a matter of finding how far the bomb needs to be from the fuselage, how fast/far the piston needs to extend to squeeze the bomb to make it blow up, etc.
@llDeadboyll It depends but generally, there's always a way around it. Although it is always better to take the extra time to cover all of your bases.
If it is a conventional plane then an autopilot can totally ignore angle of attack/slip values. If it is something PSM capable (intentional or not) then you definitely need to take care of AOA and make sure you don't stall yourself when you don't want to.
@llDeadboyll Assuming you are asking me if it is possible to make a missile autopilot without taking into account of Angle Of Attack and Angle Of Slip; Yes, I do it without those values all the time, especially for multi-firing or aircraft mounted missiles since a flight computer that's not set as the primary cockpit does not return values of angle of attack/slip and calculating them is a hassle and adds more variables that you have to transfer and more points for failure/inconsistency.
@j20m ya ur good
@j20m ^^^^^^^^^^ matter of fact reference this

@dekanii That's ok, I can make it from scratch
If I make it, would I be able to repost the tank with your permission?

+1@JJmaca please reference my other posts on how to attach ft missiles to your plane. Its not as simple as drag and drop.
@Object775blyat whatever you want. 1 is default value and 2 would mean it spools up twice as fast and so on.

Goated game of all time
+1@Thatmililitaryguy u must’ve accidentally not copied the entire variable expression. Try copying it again
@Thatmililitaryguy What do u mean by variable stack?
@kpfpz70m933 ya use it however u want
@QuesoAirlines or just dont double click the part and open its editor menu at all when moving it to avoid this problem
@QuesoAirlines So the reason it did that is not necessarily because you clicked it, but you double clicked to open the modify menu.
