+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind

+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at sakai861104@gmail.com. All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the reporter of any incident.

+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time.

+### UIParticle component
+
+`UIParticle` controls the ParticleSystems that is attached to its own game objects and child game objects.
+
+![](https://user-images.githubusercontent.com/12690315/174413976-691eb38e-7f92-4fbe-9790-8771b9dc70b2.png)
+
+| Properties | Description |
+| -- | -- |
+| Maskable | Does this graphic allow masking. |
+| Ignore Canvas Scale | Ignore the scale of the root canvas.<br>This prevents it from displaying small even in hierarchy scaling mode of `ParticleSystem`. |
+| Scale | Scale the rendering.<br>When the `3D` toggle is enabled, 3D scale (x,y,z) is supported. |
+| Animatable Properties | If you want update material properties (e.g. `_MainTex_ST`, `_Color`) in AnimationClip, use this to mark the changes. |
+| Mesh Sharing | Particle simulation results are shared within the same group.<br>A large number of the same effects can be displayed with a small load.<br>When the `Random` toggle is enabled, it will be grouped randomaly. |
+| Absolute Mode | The particles will be emitted at the ParticleSystem position.<br>Move the UIParticle/ParticleSystem to move the particle. |
+| Rendering Order | The ParticleSystems to be rendered.<br>You can change the rendering order and the materials. |
+
+NOTE: Press `Refresh` button to reconstruct rendering order based on children ParticleSystem's sorting order and z position.
+
+<br><br>
+
+### Basically usage
+
+1. Select `Game Object/UI/ParticleSystem` to create UIParticle with a ParticleSystem.  
+![particle](https://user-images.githubusercontent.com/12690315/95007361-cad0e880-0649-11eb-8835-f145d62c5977.png)
+2. Adjust the ParticleSystem as you like.  
+![particle1](https://user-images.githubusercontent.com/12690315/95007359-ca385200-0649-11eb-8383-627c9750bda8.png)

+
+<br><br>
+
+### With `Mask` or `MaskRect2D` component
+
+If you want to mask particles, set a stencil supported shader (such as `UI/UIAdditive`) to material for ParticleSystem.
+

-##### Requirement
+<br><br>
 
-* Unity 2018.2+ (Tested in Unity 2018.2.0f2)
-* No other SDK are required
+### Script usage
 
+```cs
+// Instant ParticleSystem prefab with UIParticle on runtime.
+var go = GameObject.Instantiate(prefab);
+var uiParticle = go.AddComponent<UIParticle>();
 
+// Control by ParticleSystem.
+particleSystem.Play();
+particleSystem.Emit(10);
 
+// Control by UIParticle.
+uiParticle.Play();
+uiParticle.Stop();
+```
+
+<br><br>
+
+### UIParticleAttractor component
+
+`UIParticleAttractor` attracts particles generated by the specified ParticleSystem.
+
+![](https://user-images.githubusercontent.com/12690315/174413982-b31c358a-8e1d-4b3e-a6d8-18b050b25d6f.png)
+![](https://user-images.githubusercontent.com/12690315/174311027-462929a4-13f0-4ec4-86ea-9c832f2eecf1.gif)
+
+| Properties | Description |
+| -- | -- |
+| Particle System | Attracts particles generated by the specified particle system. |
+| Distination Radius | Once the particle is within the radius, the particle lifetime will become 0 and `OnAttracted` will be called. |
+| Delay Rate | Delay to start attracting.<br>It is a percentage of the particle's start lifetime. |
+| Max Speed | Maximum speed of attracting.<br> If this value is too small, attracting may not be completed by the end of the lifetime and `OnAttracted` may not be called. |
+| Movement | Attracting movement type. (Linear, Smooth, Sphere) |
+| OnAttracted | An event called when attracting is complete (per particle). |

 ## Development Note
 
-#### Animatable material property
+### Shader Limitation
 
-![](https://user-images.githubusercontent.com/12690315/53286323-2d94a980-37b0-11e9-8afb-c4a207805ff2.gif)
+UIParticles are based on UIVertex.  
+Therefore, only xy components is available for each UV in the shader. (zw components will be ignored).  
+So unfortunately UIParticles will not work well with some shaders.  
+When using custom vertex streams, you can fill zw components with "unnecessary" data.  
+https://github.com/mob-sakai/ParticleEffectForUGUI/issues/191
 
-Animation clips can change the material properties of the Renderer, such as ParticleSystemRenderer.  
-It uses MaterialPropertyBlock so it does not create new material instances.  
-Using material properties, you can change UV animation, scale and color etc.
+- If you need a simple Additive shader, use the `UI/Additive` shader instead.
+- If you need a simple alpha-blend shader, use the `UI/Default` shader instead.
 
-Well, there is a component called CanvasRenderer.  
-It is used by all Graphic components for UI (Text, Image, Raw Image, etc.) including UIParticle.  
-However, It is **NOT** a Renderer.  
-Therefore, in UIParticle, changing ParticleSystemRenderer's MaterialPropertyBlock by animation clip is ignored.
+### Overheads
 
-To prevent this, Use "Animatable Material Property".  
-"Animatable Material Property" gets the necessary properties from ParticleSystemRenderer's MaterialPropertyBlock and sets them to the CanvasRenderer's material. 
+UIParticle has some overheads and the batching depends on uGUI.  
+When improving performance, keep the following in mind:
+- If you are displaying a large number of the same effect, consider `Mesh Sharing` feature in [UIParticle Component](#uiparticle-component).
+  - If you don't like the uniform output, consider `Random Group` feature.  
+![](https://user-images.githubusercontent.com/12690315/174311048-c882df81-6c34-4eba-b0aa-5645457692f1.gif)
+- If you are using multiple materials, you will have more draw calls.
+  - Consider single material, atlasing the sprites, and using `Sprite` mode in the `Texture Sheet Animation` module in ParticleSystem.
