So, i'm trying to add a trail to a MOPixel using lua, but, i'm failing. >_____>'

First, I tried directly creating the trail particle

No trail was seen and it lagged bigtime.

Then I tried attaching an AEmitter to the MOPixel to emit the trail particles

Again, no trail was seen but it didn't lag

What am I doing wrong?

Okay, MaximDude. I actually had this problem, but here's what you would do.

In Create



In Update.


Really should work

Worked for me :3

Still no go...
I suspect that it is me doing something wrong...

My AE was an AddAmmo AE, I changed it to an AddEffect AE, but it still doesn't show...

And my CC becaue really crashy for some reason... >_________>'
I'll have to look into this.

Thanks anyway.

first of all you are adding it to the exact same place as the original particle, so it may actually be workin but it's just behind the other one, try adding this:

if (self.Vel.X > 0.1) then trail.Pos.X = trail.Pos.X + 1; end
if (self.Vel.X < -0.1) then trail.Pos.X = trail.Pos.X - 1; end
if (self.Vel.Y > 0.1) then trail.Pos.Y = trail.Pos.X + 1; end
if (self.Vel.Y < -0.1) then trail.Pos.Y = trail.Pos.X - 1; end
(note I don't use 0 because it's very unlikely it's ever going to be exactly 0)

Also, adding things to the scene with lua has been problematic with me so yeah, if that doesn't fix it it's a problem with how you are adding it

The particle being created has PinStrength, so its supposed to stay behind the particle while it moves forwards.

In the 2nd code, I attached an AEmitter to the particle. Again, particles emitted from it would always stay behind.



It most likely is.

Emitters should be able to be attached to MOPixels. I see no reason why not.
It would make the proces of pretty glow trail creation alot easier.

I wonder if I can add sharpness to an AE... Then i'd use it directly.

I, am a ♥♥♥♥ idiot.
All this time, the LifeTime on the glow particle was set to 10... It was meant to be 1000....
Everything worked just fine from the very beginning... I just couldn't see the result...

/doublefacepalm

Thread can be closed now.

I see it's just that you were adding the velocity of the particle to the trail particle and in update you were updating the position of the trail particle to match with the leading particle, and I thought you were after some kind of trail flowing behind it rather than a static trail. You usually find the problem lies within the annoying little things like that

Actually, I am trying to do that.
A nice glowy trail behind it, but, it doesn't quite work because of the particle's speed is too high. So its just blobs at equal intervals.

Uh can I see the glows and um aemitter's code? Just the part where it is emitting the glow and the whole glow code. :3

Why would you need that?
Its a regular MOPixel with ScreenEffect and an AddEffect AEmitter emitting that pixel.
The script is attached to a round.

Well, how about this:



It's what I used for a laser gun I made yesterday. Doesn't lag at all. Here's the effect it creates:

My code works too, and the result is the same.
Though, I wanted it to be more like •••••• then • • • • • •, but that really depends on the speed of the round.

And how short you make the timer.

0/1 sim MS.
And still, • • • • • • and not ••••••••.

How fast are you shooting the bullet?
