Yet another beta tech demo. This time, it is a static AA turret (but can be mounted on a moving land vehicle provided the ground is flat or sea vehicle) that calculates the lead of the enemy aircraft; thus, the automatic aiming will not miss and there is no need for manual adjustment like the old turret. Spawn in, spawn your enemies, and the turret will do the work.

Limitations

This suffers from "triangle error", where the turret's gunnery is slightly offset from the information provided from the cockpit's location. I have thought of and drafted a function to solve this based on Law of Sines and Law of Cosines but I have not implemented it yet. Also, it only works on flat ground. Moving land vehicles are ok though. The AI can control it but it won't fire the guns (unless you damage the AI so it keeps firing the guns). This is only designed to work with the gravityless projectiles of guns.

I think it will work on ships as long as your ships do not list.

The function (click to access):


The function is fully free (it isn't that good though).

How auto-lead works

We take the rate of change of heading and assume the craft will keep that same rate of change constant. Then we calculate how long the bullet will take to get to the target's distance. Finally, we multiply the rate by the time to get the amount of correction for a successful intercept (assuming the enemy keeps its same rates). This means if your enemy is not constantly changing its course (including just going in a circle), you will have big chances to kill it with this device.

PS: It shoots down a lot of different types of planes, not just slow props. Try it out!


Addendum: AI Control

It works now, exactly like the original.

Coming Soon: PARALLAX

Now turrets don't have to be right above the cockpit... you can have more than one now

 (((TargetHeading - ((sign(Heading)<0)?(360+Heading):Heading)) + (rate(TargetHeading) * (TargetDistance / 2000))) < -90 | (((TargetHeading - ((sign(Heading)<0)?(360+Heading):Heading)) + (rate(TargetHeading) * (TargetDistance / 2000))) > 90)?((asin((sin((180 +  ((TargetHeading - ((sign(Heading)<0)?(360+Heading):Heading)) + (rate(TargetHeading) * (TargetDistance / 2000))))) * TargetDistance) / sqrt((TargetDistance * TargetDistance) + (16.25 * 16.25) - (2 * TargetDistance * 16.25 * cos((180 +  ((TargetHeading - ((sign(Heading)<0)?(360+Heading):Heading)) + (rate(TargetHeading) * (TargetDistance / 2000)))))))) + 180) / 180):((asin((sin((180 +  ((TargetHeading - ((sign(Heading)<0)?(360+Heading):Heading)) + (rate(TargetHeading) * (TargetDistance / 2000))))) * TargetDistance) / sqrt((TargetDistance * TargetDistance) + (16.25 * 16.25) - (2 * TargetDistance * 16.25 * cos((180 +  ((TargetHeading - ((sign(Heading)<0)?(360+Heading):Heading)) + (rate(TargetHeading) * (TargetDistance / 2000))))))))) / -180)

(ignore this for now, it is coming soon)

    @Brendorkus 20 dollars basic plan, 50 dollars premium, 100 dollars gold tier
    anyways, people have asked, credit is not needed and you could claim it as your own if you like. still flaws to be fixed and worked out.

    Hello - I’ve set a range of 5km so your target should be closer than that. If you open the turret up you can change this by changing the 5000 in overload of the heading rotator. @Loldydu374

    @232287168147825 So currently the turret has 0 degrees depression, how do i make it able to aim downwards? (It currently cannot)

    That is because it is rigged to only work a a ground turret but with few changes to the equation it can be fixed, note that only the pitch rotating one suffers from this problem so you should be able to fix it by comparing them to each other@Zakhaev245

    I would like to know how you managed to make the tower give a 360°, because even with the Mods I can't, it always stops at 180°. Note: I'm using your idea to make a World War II AA.

    How do you adjust the turret for different muzzle velocities?
