Also I just came up with that function based on wikipedia so it may/may not work perfectly, but overall it does work well.

It works perfectly when firing horizontally, but it gets all wonky when the shot is angled, as in, the frequency increases. I think it needs to call for the overall velocity instead of X-velocity, if it is to be used at an angle.
Here's some screens to show you how it looks like right now:

Without Lua Frequency can be adjusted.



With Lua, horizontally



With Lua, diagonally



As you can see, the horizontal Lua wave looks far better than the non-Lua wave, but it looks wonky when fired diagonally. Note: I divided the amplitude (as provided by Mind) of Grif's script by 10, else it would make HUGE waves, that hammered into the ground instantly.
I don't know if it's possible to make the Lua wave usable at an angle, but i'm certain that my hacky method works at any angle... But it doesn't look as smooth.

Better than nothing, Shook.

I hate to do this to you, Shook (since it's going to be jargon) but you could run a proximity check to determine the parent, then if the aim angle is above a certain level it'll decrease the amplitude, or raise the wavenumber.

Basically, the function I posted has most of the arguments from the wikipedia page on sine waves. So, uh, learn from those terms and figure it out.

ALTERNATELY oh wait no--well, what you could do is, for the last argument in the sinewave function (self.Pos.X) replace it with:

self.Pos.X - self.Pos.X / 2

That should still get you a good wave, but less energetically overall.

Lemme go test some different things here.

Off topic from Sine waves, and such, Beware the Zero Division Cannon:

ah - ha!

Some indie devs helped shed light on sine waves. Functional code in any direction (except sometimes straight up):

To decrease frequency (how many waves per second aka the distance between wave tops) simply set the 20 to something else that's higher. Wavenumber can be just about anything, angvel the same, and phase has to be self.pos.x or at least based on that. And then, as mind explained, amplitude is the height of the wave.

Nice, it works like a charm! Thanks Grif.
I'm starting to think that the fact that it can only fire horizontally might just be a quirk with the weapon, kind of like how the Exterminator in the Pelian Army has an erratic flight path. To compensate, it can be deliciously powerful...

To fix the fact that it goes for a little while and then goes onto the sine path you can remove the timer lines:

Yes, we've been over this. Fun isn't it?

Just for fun, a sawtooth weapon function:

Hmmm... on sine waves, how about making the gun shoot a zero-gravity, constant speed invisible particle, but then have the invisible particle be trailed by an oscillating, visible and destructive AEmitter? So, if you 'hold' the invisible particle in place all you see is the AEmitter going up and down. And since the invisible particle will automatically align with where you aim the gun (I mean the angle), you'd have a sine wave which aligns with the angle you point the gun at. To fix frequency you'd just have to adjust the speed at which it oscillates. How's this? The oscillating part could be made into a lua file or something...

I'm pretty sure that this is impossible to do with conventional coding, and quite complicated to do with Lua. So for now, it stays how it is (as in, with Grif's neat-o script applied), so nobody will have to break their brains on it. =P

There's just one thing i've been thinking about... Would it be possible to make the Drones' guns controllable with Lua? Just like, make them fire when either the users Fire button is pressed, or when a pre-mapped key is pressed. It's probably not possible to make the attached emitter shoot, considering the lack of control over attachables, but wouldn't it be possible to make the drone itself spawn the shot and effects?
I also just thought about if it would be possible to make the drones flip horizontally, when flying backwards. Just so they don't actually fly backwards, y'know?
Well this wasn't nearly as subtle as i hoped it would be. >.>

Edit: Shooting problem solved, thanks to Grif.

*Double post lel* (I wish i didn't have to, but ehh... Needs a bump, this)

This is like, a progress update for your convenience.

Firstly, the old drones have been upgraded with manual firing and such, thanks to Grif. They all work very nicely, according to both me and my beta tester, Ragdollmaster.

Secondly, i've added the Death Drone, which kills anyone dumb enough to get too close.

Thirdly, i'm in the progress of making heavy versions of all the drones.



Huzzah.

Shook, let it never be said that you ever let me down.

Hoo-hah!

Anyways, i've made almost all of the heavy drones now, but there's one thing i need to ask you guys, provided that any of you can be assed to press the "Reply" button... Should i make heavy digger drones as well? I just feel that they'd be a little redundant, but ehh... If you want, i'll make them.
