Okay so i’m not sure if I put this in the right category but I would like to know how to make advanced particles like the one in this game.
Here is how it looks like:
I really want to know how the person made the laser beam thing move like that for the weapon. So if you have any idea on how the person made it please let me know. 
They are not advanced, they probably just played with the particle emitter properties and got there, hoe a lot of devs(including me) try making cool particles.
For the laser beam I don’t know the exact things but here are my predictions:
LockedToPart = true
Size = 1, 0.5, 0 – Set this to your number sequence(ask me if you don’t know)
But, it might be a beam, not a particle emitter.
Alright I will try doing that thanks for the help!
For the squiggly effect around the sword, it looks the developer used a series of beams that are connected to each other. If you look carefully you can identify 3 different parts in the effect. All the way at the left end you can see a beam move up and down. Just to the right of it you can see a zigzag beam moving quickly. But then further to the right that zigzag effect is moving more slowly. I believe these are 3 different beam effects aligned in a way that it looks like a seamless illusion. Here’s a more descriptive picture to explain how it works:
(I messed up in the picture a little, imagine the green area being wider than the purple area)
The green and purple areas are two different beams with the same texture that are connected to the black attachments (dots) touching their sides. Because both beams use the same texture, they line up perfectly. The purple zigzag is wider than the green zigzag. This way the purple beam is a little stretched compared to the green zigzag which creates the illusion of the purple area moving faster. The orange line is a third beam connected to the red attachment and the black attachment all the way on the left. The red attachment will move up and down in a pattern that matches up with the speed of the green beam such that it looks like the full zigzag is moving as one seamless line.
