Particle effect help?

Unity Engine
1

Hi there, I am new to Unity’s particle system.

I am trying to create a certain effect for use on my 3D game’s canvas.

I tried to make it have:
10 hard edged red triangles emitted radially, spawning once, almost like an explosion/burst, (not spewed out continuously) over half a second.

Any help in guiding me towards the effect I am going for would be greatly appreciated :slight_smile:

Hi @MaltedWheaties

“10 hard edged red triangles emitted radially, spawning once, almost like an explosion/burst, (not spewed out continuously) over half a second.”

I think that can be interpreted in many ways… better show a picture of what you think you want…

Besides, this is 2D graphics forum, I don’t think there is one for particles, but I see many particle system questions in General Graphics:

But in general, you can use circular emission shape and meshes for triangles for example.

In addition to the great answer from eses, there are Burst emission settings in the Emission Module, for the one-shot emission you want.

In the shape module, perhaps set the emission type to Burst Spread, to have the particles distributed evenly around your circle, too, instead of randomly. If that’s what you want :wink:

Looks like it is! Thanks :slight_smile:

@richardkettlewell my only other question is that how do you go about making it a triangle shape? I tried putting the triangle sprite onto a material and using that, but it was just red :confused:

@MaltedWheaties

I’m not Richard, but I’ll answer first :slight_smile: .You can use mesh or texture on your particle (or both). You don’t have to use default particle shape. Also, like @richardkettlewell said, you can use burst emission setting… and in addition to that, you can also modify size, velocity, rotation and material of particles and you can also align the particles to velocity if that is needed. Like this (probably not what you need, but anyway…):

@eses that’s exactly what I’m going for! Currently I think I have rotation, size, etc settings done, however please could I a peek at those burst settings if that’s ok? I’ve never really worked with particles before :wink:

    “however please could I a peek at those burst settings if that’s ok?”

For that you only need to remove time based particle emission, and replace it with some values in burst settings:

So instead of movement or time, you emit burst at set time, often in start i.e. TIme 0.
