Let's start the reconstruction
Right click and select
FX => Niagara System to create. 
4.
Create Niagara System
Select
Empty template, click + and Finish 
5.
Create Niagara System
As a result, we get a
Niagara System asset, click to open it. 
6.
Empty Niagara System
You can see that we have an empty Niagara system.
7.
Spawn Rate
Click on the
+ sign to the right of the Emitter Update to add the Spawn Rate module.Spawn Rate: Number of particles per second to spawn. 
8.
Spawn Rate
Set the
Spawn 5.0 particle per second.
Spawn Rate value to 5.0.Spawn 5.0 particle per second.
9.
Attributes
An important aspect of Niagara is something we call
An Emitter level attribute, for example, is a single piece of data for the entire emitter. In this tutorial here, a
Attributes. These are bits of data that are saved alongside the various scripts.An Emitter level attribute, for example, is a single piece of data for the entire emitter. In this tutorial here, a
Float, called Emitter.SineWave. 
10.
SineWave
Click the
+ sign to the right of the Emitter Attributes to add a float attribute. 
11.
SineWave
Name this new property
SineWave. 
12.
SineWave
Drag this property under
If dragged into
By setting it in
Emitter Update.If dragged into
Emitter Spawn, its value would only be set once, on the first frame the emitter was born.By setting it in
Emitter update, that Attribute gets a new value every frame. 
13.
Edit Attribute
Modify the value type of the property to
Sine function dynamic input. 
14.
Edit Attribute
Set the value type of
Normalized Angle to Multiply Float 
15.
Edit Attribute
Link
A with the Age attribute of the emitter 
16.
Edit Attribute
Edit the value of
In this case, we make ourselve a sinewave which is accessible by every single particle in the emitter, and we sample that sinewave in the "Add Velocity" module to spray oscillating particles as time goes on.
B to 0.2.In this case, we make ourselve a sinewave which is accessible by every single particle in the emitter, and we sample that sinewave in the "Add Velocity" module to spray oscillating particles as time goes on.
17.
Initialize Particles
Select

Mesh Scale Mode is Uniform and its value is 3.0 
18.
Add Velocity
Add
Add Velocity module to the Particle Spawn section. 
19.
Add Velocity
Click the first
Fix issue button to add its dependency on the SolveForcesAndVelocity module. 
20.
Edit Velocity
Set the value type of
Velocity to Rotate Vector 
21.
Edit Velocity
Set the
Z value of Vector To Rotate to 100.0. 
22.
Edit Velocity
Set the value type of
Pitch to Multiply Float 
23.
Edit Velocity
Set the
A value of Pitch to the SineWave of the emitter. 
24.
Edit Velocity
Set the
B value of Pitch to 24.0. 
25.
Edit Velocity
Set the
time increment (Delta Time) of the velocity as a sine function (Sine). 
26.
Edit Velocity
Set the value type of
Normalized Angle to Multiply Float 
27.
Edit Velocity
Sets the
A value of Normalized Angle to the Age of the emitter. 
28.
Edit Velocity
1. Set the
2. Set the
3. Set the value of
B value of Normalized Angle to 0.2.2. Set the
Scale value to 0.5.3. Set the value of
Bias to 1. 
29.
Initial Mesh Orientation
Add
Initial Mesh Orientation module to the Particle Spawn section. 
30.
Initial Mesh Orientation
Set the value of
Orientation Vector to the Velocity of the particle. 
31.
Update Mesh Orientation
Add
Update Mesh Orientation module to the Particle Update section. 
32.
Update Mesh Orientation
Add
Update Mesh Orientation to the Particle Update module. 
33.
Scale Mesh Size
Add
Scale Mesh Size module to the Particle Update section. 
34.

Edit the
Scale Factor's value to Vector 2DFrom Float. 
35.
Scale Mesh Size
Set the value type of
Value to Float from Curve 
36.
Scale Mesh Size
Select the first point and edit its value to: (Time is
0.0, Value is 0.0). 
37.
Scale Mesh Size
Mouse over the small red circle, right click, and select
Add key to Curve. 
38.
Scale Mesh Size
Set the
Time of the newly added point to 0.25 and the Value to 1. 
39.
Scale Mesh Size
In the same way, add a point:
Then select each point, right-click, and select
Time is 0.75 and Value is 1.Then select each point, right-click, and select
Auto. 
40.
Remove Sprite Renderer
Select
Sprite Renderer, right-click, and select Delete. 
41.
Add Mesh Renderer
Add
Mesh Render module to the Render section. 
42.
