@griges so, you need variables first for where you are headed. im gonna call these (a,b,c) this is the location of wherever you wanna go. and im not gonna use c, because I only care about horizontal distance atm.
.
The variables of your plane are Longitude, Latitude, Altitude and Heading. imma call these (x,y,z) and theta (theta for angle).
.
to find the vector between you and your destination distanceX = a-x distanceY = b-y
.
Also I wall call the length of the vector between you and destination magDist. this is just sqrt(pow(distanceX,2) + pow(distanceY,2)) think a^2 + b^2 = c^2
.
im gonna make sure the length = 1 in equation below
.
for the dot product = sin(Heading)*(distanceX/magDist) + cos(Heading)*(distanceY/magDist)
.
Now you have a dot product, yippee!
.
with the dot product use acos(dot) for an angle.
to make is useful the angle between you and the target is = acos(dot)-heading
.
putting this all into as little lines as I can acos(sin(Heading)*((a-x)/sqrt(pow(a-x,2) + pow(b-y,2))) +
cos(Heading)*(b-y/sqrt(pow(a-x,2) + pow(b-y,2)))-Heading
.
edit: just fixed smth dumb
@griges its not scary haha, it looks it but in simple, if you know trig and simple vectors, you can use two formulas and a little neatening to get a result. Im happy to write it out as a big equation if you want
@griges Ok, i think i proof read that fine, the last thing you need is a little formula with the dot product i mentioned earlier. using a formula. and assuming everything was normalised earlier all you need to know is that acos(A.B) = the angle between two vectors, which is fun already.
.
and then im 90% sure because its headings the angle you have to turn to face the right direction is turn_angle = acos(A.B) - Heading
@griges basically, you know trigonometry with triangles?. SOH CAH TOA
all of that in this is solely for triangles, the powers are just pythagoras a^2 + b^2 = c^2
.
for this maths im using something called column vectors, which is just a nice way to show vectors, think of (2,3) as 2 along (right), 3 up. help here
.
Also I should say the maths assumes that youre looking down on the world from a birds eye view, which doesnt really mean anything important. just that up means north.
.
There is a few variables we know always, where you are (x,y,z) = (Longitude, Latitude, Altitude), which way you are headed as a heading. headings are the angle away from north you are facing. To use the heading, for your x use cos(Heading), for your y, use sin(Heading) help here.
.
Also you always know your destination. To find a vector between you and your destination you can use : (destination) x ,y ,z - (your current) x, y, z.
Because vectors are cool and (1,2,3) - (1,2,3) works by x-x, y-y, z-z. which results in (0,0,0) because there is no difference. help here
.
Now, with your triangle knowledge and simple vector knowledge you can use a few important facts. you need to normalise these vectors. This means the hypotenuse of the triangle has a length of 1, always. but it still points in the same direction. you can do this by dividing each side of the triangle by the hypotenuse length. help here
.
next step is the scalar product which sounds scary, but in short we have two vectors, our heading and the vector between us and our destination, which i will call A and B. to find 'how related they are' use the scalar/dot productA.B = x*x + y*y (multiply the x of A and B together and add it to the y of A time y of B).
.
This creates a number between -1 and 1. and basically it tells you a bunch. if its 1. you are looking directly at the island, if its 0 you are looking perpendicular to it. and -1 if you are looking the opposite direction
@griges next point? Basically, the distance is the hypotenuse of a triangle made with your current x,y, then using another points x and y, you find a distance.
.
for the direction i use a little vector maths, basically treating the heading of your aircraft as a normal vector, and comparing it to the (normalised) vector between you and the location. I use the scalar product for this.
.
im happy to explain in more detail, just not sure what you mean
@RepublicofWrightIsles i was gonna write out a bunch of stuff, but like in simple, its not that deep, 'true' communism is just homogenous equality etc.
.
I am not defending past atrocities. Ive dug myself a pit here
Use sets of asterisk like brackets around text to bold (2 asterisk pairs), or italics (1 asterisk pair). Or 3 is both
You can use backticks for the red text (useful to show off funky trees stuff)
Using amounts of hashtags, one hashtags is the largest, then adding more decreases sizes.

@griges yeah, just thought a ufo is probably
One of the few things that could need it, you could try like using a bit of hollow fuselage to like make a shadow over the lights to make them pop more/dark painted fuselage around the lights. But there isn’t really a way to increase brightness past emission 1 (with any effect) to my knowledge
also if u wanna swivel flight cam & or controls, make sure to have the main cockpit/flight comp remain in the same position and rotation, for the sake of physics
For the weapon you could make a tractor beam, using a negative value for the impactForce property on a gun. not 100% sure what you mean with the lights, but I recommend hooking them all up to a variable, in case you wanna change how they activate all at once, or use emission painted parts.
@StinkyRice A good practice is to make the arms weightless, it decreases shake, also not to mention I think mass scale makes rotators more stable, but I think joysticks have their own dampners etc built in
When i do bother, i wing it, usually have AG group buttons to the left, I like the fighter throttle to the left, joystick to the right, then some sorta screen dead ahead, any 'emergency' buttons by the feet. Needless to say, I have not really ever looked at a plane cockpit
Birds are an amazing shout, if they do a minimap I reckon it'll be a "screen" part or something like that, im slightly worried they might not add stuff like that because people managed to make it with normal stuff though. The Ai needs a uniform improvement too
