^click^ for target plane to test with

I woke up today and the new beta featured a new parameter: fuseInput. This immediately got me thinking, and I came up with this. While the new auto fuses can simply be timed to the linear distance, I decided on something more complicated as cannon projectiles are pulled down by gravity. As well as that, I also upgraded the old turret's simple funky trees with something much more... fun... to compensate for the force of gravity.

It works best at longer range and has a built in range of 20km. This can be put on planes if gyros are used instead of rotators.

Function Physics Explanation

(But no Funky Trees! So people who took Physics can understand easily!)
Thanks to SnoWFlakE0S for linking the following equation:

This allows the cannon to take account gravity to hit (X,Y). These being calculated on a plane based from the turret's heading using trig.
The heading is nearly the same as the old turret. Basically, the fun two-vector projectile motion but simplified and solved into 1 equation with the variables I need/have.

The fuse is different than a linear calculation, which would calculate the amount of time the shell would reach linearly (Distance/Speed). Since the projectile is a two-vector object, we find the horizontal vector and then divide by the total horizontal distance to attempt to explode near the target, unlike the normal linear method which would result in the shell exploding too early as the linear path would be shorter than the parabolic one.

To become cool and reason why it looks so intimidating, is we need to find the horizontal vector of the already gravity-corrected turret angle, (as opposed to the target’s component of horizontal displacement, which is from straight TargetElevation) meaning we plug the entire equation into the trig.


Want to know the license for these FUNKtions? look at a rotator lol

    And the code given by WNP78 worked better at shooting down planes.

    So.. how so i modify this so it Can work with a different projectile velocity than the preset one that idk how to modify

    Its only weakness is planes that is constantly changing distance from the turret like planes that are moving away or towards the turret

    The elevation / azimuth is aight. But the fusing (that determines when the flak should explode, preferably next to the enemy) is unreliable and explodes too far or too short sometimes @Hellosss38

    If you make it so it has no recoil then the fire rate goes up.

    @NumbersNumbersTheMan The entire problem, I assume, is that the target is moving and the fuse is set to detonate at the point the plane was when the shells fired instead of where the plane is when the shell passes by the plane... Because even with the Snowflake code the shells still pass by the plane (even the slowest vanilla bushplane, that is) and harmlessly detonate 50 feet (if not 100 or more) behind it...

    @ThomasRoderick unfortunately, the function

    ((cos(TargetElevation) * TargetDistance)/(cos((atan(((pow(2000,2)) - (sqrt((pow(2000,4)) - (9.81 * ((9.81 * pow((cos(TargetElevation) * TargetDistance), 2)) + ((2 * ((sin(TargetElevation) * TargetDistance))) * pow(2000,2)))))))/(9.81 * (cos(TargetElevation) * TargetDistance))) + rate(TargetElevation) * (TargetDistance / 2000)) / 1) * 2000))
    

    has issues when setting horizontal component fuses. I will take a look some day, but I am busy. A guaranteed fuse that will be a little short and more inaccurate as targets get farther is a linear fuse, targetDistance / 2000

    There's one slight problem: the shells detonated nowhere near the enemy plane, so unless we can get a direct hit it's not really working... Is it due to lag?
