+
+## Usage
+
+### UIParticle component
+
+`UIParticle` controls the ParticleSystems that is attached to its own game objects and child game objects.
+
+![](https://github.com/mob-sakai/ParticleEffectForUGUI/assets/12690315/3559df45-63e7-4c4c-9233-f455779efa29)
+
+| Properties | Description |
+| -- | -- |
+| Maskable | Does this graphic allow masking. |
+| 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. |
+| Position Mode | **Absolute:** Emit from the world position of the `ParticleSystem`.<br>**Relative:** Emit from the scaled position of the `ParticleSystem`. |
+| Auto Scaling | Transform.lossyScale (=world scale) will be set to `(1, 1, 1)` on update.<br>It prevents the root-Canvas scale from affecting the hierarchy-scaled `ParticleSystem`. |
+| Rendering Order | The ParticleSystem list to be rendered.<br>You can change the 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 your existing ParticleSystem prefab
+
+1. Select `Game Object/UI/ParticleSystem (Empty)` to create UIParticle.  
+![empty](https://user-images.githubusercontent.com/12690315/95007362-cb697f00-0649-11eb-8a09-29b0a13791e4.png)
+2. Drag & drop your ParticleSystem prefab on UIParticle.  
+![particle3](https://user-images.githubusercontent.com/12690315/95007356-c6a4cb00-0649-11eb-9316-562f4bce3f31.png)
+
+<br><br>
+
+### With `Mask` or `RectMask2D` component
+
+If you want to mask particles, set a stencil supported shader (such as `UI/UIAdditive`) to material for ParticleSystem.
+If you use some custom shaders, see [How to make a custom shader to support Mask/RectMask2D component](#how-to-make-a-custom-shader-to-support-maskrectmask2d-component) section.
+
+![](https://user-images.githubusercontent.com/12690315/95017591-3b512700-0695-11eb-864e-04166ea1809a.png)
+
+
+<br><br>
+
+### 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://github.com/mob-sakai/ParticleEffectForUGUI/assets/12690315/ea6ae0ed-f9a8-437c-8baa-47526303391e)

+
+| 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) |
+| Update Mode | **Normal:** Update with scaled delta time.<br>**Unscaled Time:** Update with unscaled delta time. |
+| OnAttracted | An event called when attracting is complete (per particle). |
+

+
+## Development Note
+
+### FAQ: Why are my particle effects not displayed correctly?
+
+If `ParticleSystem` alone displays particles correctly but `UIParticle` does not, please check the following points:
+
+* [Shader Limitation](https://github.com/mob-sakai/ParticleEffectForUGUI#shader-limitation)
+  * Most cases can be solved by using `UI/Additive` or `UI/Default`.
+* Particles are masked
+  * `UIParticle` is maskable.
+  * Set `Mask` or `RectMask2D` component properly.
+* Particles are too small
+  * If particles are small enough, they will not appear on the screen.
+  * Increase the `Scale` value.
+  * If you don't want to change the apparent size depending on the resolution, try `Auto Scaling` option.
+* Particles are too many
+  * No more than 65535 vertices can be displayed (for mesh combination limitations).
+  * Please set `Emission` module and `Max Particles` of ParticleSystem properly.
+* Particles are emitted off-screen.
+  * When `Position Mode = Relative`, particles are emitted from scaled position of the ParticleSystem, not from the screen point of the ParticleSystem.
+  * Place the ParticleSystem in the proper position or try `Position Mode = Absolute`.
+* Attaching `UIParticle` to the same object as `ParticleSystem`
+  * `Transform.localScale` will be overridden by `Auto Scaling` option.
+  * It is recommended to place `ParticleSystem` under `UIParticle`.
+
+
+<br>
+
+### Shader Limitation
+
+The use of UI shaders is recommended.
+
+- 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.
+- If your custom shader does not work properly with UIParticle, consider creating a custom UI shader.
+
+#### Built-in shaders are not supported
+
+UIParticle does not support all built-in shaders except for `UI/Default`.  
+If their use is detected, an error is displayed in the inspector.  
+Use UI shaders instead.
+
+#### (2019.4 or earlier) UV.zw components will be discarded
+
+UIParticleRenderer renders the particles based on UIVertex.  
+Therefore, only xy components is available for each UV in the shader. (zw components will be discarded).  
+So unfortunately UIParticles will not work well with some shaders.  
+
+#### (2019.4 or earlier) Custom vertex streams
+
+When using custom vertex streams, you can fill zw components with "unnecessary" data.  
+https://github.com/mob-sakai/ParticleEffectForUGUI/issues/191
+
+
+<br>
+
+### Overheads
+
+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.
