Another question...

[cpaca]

Ok, so I might as well say what i'm trying to do. 
Attached is a script which is supposed to send particles to enemy particles. 
I will deduct how I got my problems [so you can see if maybe the problem exists elsewhere?] 
Createparticle(CurrentPixelCoords Direction[see below] Speed(1) Health(1) IsEnemy)
Works correctly! 
Direction:
<-particley <-playery sub <-particlex <-playerx atan2 ->direction
The way the error appears i *believe* this works as "intended"
Then I have a do loop where I take a list of particles in range...
but it doesn't run (I can tell because I put a trace in there)
So this is where the problem occurs: 
The one line of code I don't fully understand [that and atan2, but that's math-stuff and I mostly know how it works [Basically, tangent]] 
CurrentCoords <-range 0 <-IsEnemy not GetParticlesInRange ->particles 
IsEnemy is self-explanatory
Earlier: 40 ->range 

TL;DR
How does GetParticlesInRange work? 
Can I set it to a variable [e.g. ->particles]
What are the inputs [and the order of the inputs] 
And please don't just go off this TL;DR; The problem may stem off of somewhere else.

Let's see...

Your script does not yet turn the module invisible when it is destroyed. Easily fixed by a "<-Exists eq0 if" block before the pause check.

From the post you wrote, I have no idea what your issue is. Directing your new particles?

Inside this spoiler is an (untested) upgraded form. Length.

Edit:

GPAR works (according to the wiki, our go-to source of information) as you seemed to be using it. The atan2 line also looks good. GPAR returns a list of particles, which can be stored.

You will note that I have changed the GPAR and associated code to use GetNearestTarget - this offloads it onto the engine level code, which is much more efficient and can take advantage of V's backend access, making optimisations such as stopping the search as soon as a suitable particle is located.

If this adjusted script does not work for you, I can look at another time. I didn't have time to test, and I noticed two typos when doing this edit, now fixed.

Well then... It has a similar angle problem of where it lands [But using GetNearestTarget is good to know, lol] 
But instead of going to 0,0... 
Well, it goes to somewhere... dunno how it chooses that place, always goes the same direction.
If you want my fun story [but it breaks CW3 lore] open spoiler

My suspicion is that Platius is in this timeline and the particles are attacking Platius

I'll open it up later, then.
