Xtensity's "Spaceman Turret V6" Tutorial, "Head Shots FTW"

[Xtensity]

What are you building? Watch this video for a demonstration.
[ame=http://www.youtube.com/watch?v=t32EdNgaUyU]YouTube - Spaceman Turret V6[/ame]

This is a pure picture tutorial of my 6th revision of my "Spaceman Turret"
The whole idea behind this is to use on any enemy.
If they duck you press 2 and if you want to head shot them standing you press 1
The number wired to 1 wire mod is a head shot standing, and 2 is a head shot while ducking, no number pressed is a normal shot (feet on human)

The main reason I made this was due to space build, I am in flat grass just for an open area to test the range of this turret, which it can head shot an enemy from across the map. It takes a second to aim but yeah..

N@Spaceman Turret V6
I@Elevation Bearing Dist Roll Num
O@ElevationThrust BearingThrust RollThrust
BearingThrust = (Bearing+$Bearing*10)
ElevationThrust =(HeightAngle+$Elevation*10)
RollThrust = (Roll+$Roll*5)
Bearing == 0 -> BearingThrust = 0;
Elevation == -90 -> ElevationThrust = 0;
HeightAngle = Elevation + atan(Num/Dist)

I know little trig so I used orbs trig function from his head shot turret on mine, the rest of everything else is made by me.

This expression is so accurate when it adjust to the targets bearing within 3-5 seconds or less, I haven't counted, it gets to .001 bearing and elevation, now if you tell it to aim for the head it will say the elevation is off


Yeah in this picture I said turret on accident lol but I mean thrusters, don't get it mixed and expect turrets to thrust the turret lol.

Ok i was taught that stuff in trig 3 years ago and currently doin advaced trig at senior highschool but i had to look up the english terms on google lol (im greek) . I havent watched Orb's tut on how to do the headshot but i guess that since u know the elevation which u tweaked to match the oposide side , u also know the distance which is the bottom side , u were able to find the angle (θ) with the tangent and output it to the either pitch or roll thrusters. Anyways what i dont understand in ur e-gate is the +*'s u got there what kind of function are those .

[drpepper]

Is the +* in your e gate the delta?? If soo sweet, I didn't know the formula for a delta.

[Xtensity]

WTF!

Why do the delta things always disappear the code gets ass fucked! It doesn't make any sense! I cant post the code since it keeps doing this ffs and idk how to fix it.

No dr its not, the delta for a variable is a dollar sign before the variable.

Aspras


Its like this

Yup thats exactly what i typed right there lol. Anyways im really getting pissed off with my turret im still trying to get the firing thing positioned correctly , no matter where i position it the god damn bearing is at 0.001 and the bullets go nowhere near the guy .

[drpepper]

Sweet thanks so much Xtensity, I never knew what that blasted delta command was.

Hm you sure? I'll go onto Gmod and make one using my tutorial and upload the adv dupe file and you can compare them.

Also one thing. I don't know shit about trig really just basics.

But what do sin and cos have to do with right triangles at all(not relating to circles) if Atan can get you the angle of a point....

Also whats your elevation go to when its aligned or w/e, show me a picture.

Edit, I added the adv dupe file.

[Aspras]

You use the sine to find the angle when u know the oposite side and the hypothenuse length , you use the cosine instead to find the angle again if u know the bottom side's length and the hypothenuse the tangent is currently the only trig function used because we know the distance which is the bottom side and the height of the player which is the oposite side when the elevation is at 0. Its all basic trigonometry and you can use those 3 functions to find any of the 2 angles in the triangle as long as it has an angle which is 90 degrees it doesnt matter if its right , left sided it could be rotated as well when watching it from the side its always the same thing as long as 1 of the angles of the triangle is 90 degrees. Also the most accurate and fast way to aim in the z axis would be to use the pitch or the roll to rotate towards your target and its easier to use that instead of the elevation where u have to add 180 and stuff.



PS: I realised why my turret wouldnt even aim close to the target even though the bearing was 0.001 , i thought about it a little bit and i realised that the beacon sensor has to be positioned in the exact middle of the object so that its x , y and z compared to the object itself are 0.

You know you could put th gyro inside the expression ship and save yourself another prop. You also only need 1 thruster each for yaw, pitch and roll (looks like you got two)(would also save you another few props).

That would make it aim slower if it used less thrusters, and I can't put the gyro inside the chip, I tried it and it was an utter fail. It updated but it spazzed out since it did not work properly, I did it the right way it just didn't work.
