# [5.0.0-preview.2](https://github.com/mob-sakai/ParticleEffectForUGUI/compare/v5.0.0-preview.1...v5.0.0-preview.2) (2024-06-20)

### Bug Fixes

* 'Resource ID out of range in GetResource' error in overlay rendering mode ([ff78b6f](ff78b6fe32)), closes [#308](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/308)
* `UIParticle.transform.localScale` does not scale particles ([491ee7b](491ee7b0c3)), closes [#313](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/313)
* despite not using the size module, particles become smaller based on their z position ([c96ddf2](c96ddf293e)), closes [#316](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/316)
* the ParticleSystem's localPosition drifts at certain scales due to floating-point precision issues ([a9c2b19](a9c2b19edf)), closes [#299](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/299) [#312](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/312)
* UIParticle is scaled by canvas size even when `AutoScalingMode.None` and `ScalingMode.Local` ([63b24d8](63b24d8a8b)), closes [#313](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/313)
* UIParticle is scaled incorrectly with nested canvases ([c95d8c6](c95d8c6b17)), closes [#313](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/313)

### Features

* remove overlay window (editor) ([fc3fbdd](fc3fbdd230))
* reset previous position on start play for world space simulation ([e741584](e741584507)), closes [#303](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/303)
* restore `Transform.localScale` when setting `autoScalingMode` to something other than `Transform` ([dfb94f4](dfb94f4bad))

+## ⚙ Installation
+
+_This package requires Unity 2018.3 or later._
+
+#### Install via OpenUPM
+
+This package is available on [OpenUPM](https://openupm.com) package registry.
+This is the preferred method of installation, as you can easily receive updates as they're released.
+
+If you have [openupm-cli](https://github.com/openupm/openupm-cli) installed, then run the following command in your
+project's directory:
+
+```sh
+openupm add com.coffee.ui-particle
+```
+
+#### Install via UPM (using Git URL)
+
+Navigate to your project's Packages folder and open the `manifest.json` file. Then add this package somewhere in
+the `dependencies` block:
+
+```json
+{
+  "dependencies": {
+    "com.coffee.ui-particle": "https://github.com/mob-sakai/ParticleEffectForUGUI.git",
+    ...
+  }
+}
+```
+
+To update the package, change suffix `#{version}` to the target version.
+
+* e.g. `"com.coffee.ui-particle": "https://github.com/mob-sakai/ParticleEffectForUGUI.git#4.6.0",`
+
+Or, use [UpmGitExtension](https://github.com/mob-sakai/UpmGitExtension) to install and update the package.

+
+## ⚙ Upgrading from 3.x/4.x to 5.x
+
+### Breaking Changes
+
+- The default value of `UIParticle.scale` has been changed from `10` to `1`.
+- `UIParticle` no longer inherits from `MaskableGraphic`.
+- 
+
+<br><br>
+
+## 🚀 Usage
+
+### UIParticle Component
+
+`UIParticle` controls the ParticleSystems that are attached to its own game objects and child game objects.
+
+![](https://github.com/mob-sakai/ParticleEffectForUGUI/assets/12690315/3559df45-63e7-4c4c-9233-f455779efa29)
+
+- **Maskable**: Does this graphic allow masking.
+- **Scale**: Scale the rendering. When the `3D` toggle is enabled, 3D scale (x, y, z) is supported.
+- **Animatable Properties**: If you want to 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. A large number of the same effects can
+  be displayed with a small load. When the `Random` toggle is enabled, it will be grouped randomly.
+- **Position Mode**: Emission position mode.
+    - **Absolute:** Emit from the world position of the `ParticleSystem`.
+    - **Relative:** Emit from the scaled position of the `ParticleSystem`.
+- **Auto Scaling**: `Transform.lossyScale` (=world scale) will be set to `(1, 1, 1)` on update. It prevents the
+  root-Canvas scale from affecting the hierarchy-scaled `ParticleSystem`.
+- **Rendering Order**: The ParticleSystem list to be rendered. You can change the order and the materials.
+
+**NOTE:** Press the `Refresh` button to reconstruct the rendering order based on children ParticleSystem's sorting order
+and z-position.
+
+<br><br>
+
+#### Basic Usage
+
+1. Select `GameObject/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>
+
+#### With Your Existing ParticleSystem Prefab
+
+1. Select `GameObject/UI/ParticleSystem (Empty)` to create UIParticle.
+   ![empty](https://user-images.githubusercontent.com/12690315/95007362-cb697f00-0649-11eb-8a09-29b0a13791e4.png)
+2. Drag and drop your ParticleSystem prefab onto UIParticle.
+   ![particle3](https://user-images.githubusercontent.com/12690315/95007356-c6a4cb00-0649-11eb-9316-562f4bce3f31.png)
+
+<br>
+
+#### With `Mask` or `RectMask2D` Component
+
+If you want to mask particles, set a stencil-supported shader (such as `UI/UIAdditive`) to the material for
+ParticleSystem.
+If you use some custom shaders, see
+the [How to Make a Custom Shader to Support Mask/RectMask2D Component](#how-to-make-a-custom-shader-to-support-maskrectmask2d-component)
+section.
+

+
+<br><br>
+
+### Script usage
+
+```cs
+// Instantiate ParticleSystem prefab with UIParticle on runtime.
+var go = GameObject.Instantiate(prefab);
+var uiParticle = go.AddComponent<UIParticle>();
+uiParticle.scale = 100;
+
+// 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)  
+![](https://user-images.githubusercontent.com/12690315/174311027-462929a4-13f0-4ec4-86ea-9c832f2eecf1.gif)
+
+- **Particle System**: Attracts particles generated by the specified particle system.
+- **Destination 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. It is a percentage of the particle's start lifetime.
+- **Max Speed**: Maximum speed of attracting. 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**: Update mode.
+    - **Normal:** Update with scaled delta time.
+    - **Unscaled Time:** Update with unscaled delta time.
+- **OnAttracted**: An event called when attracting is complete (per particle).
+
+<br><br>

+## 🛠 Development Note
+
+### Compares the Baking mesh approach with the conventional approach
+
+- **Baking mesh approach (=UIParticle)**

+    - ✅ Rendered as is.
+    - ✅ Maskable.
+    - ✅ Sortable.
+    - ✅ Less objects.

+### 🔍 FAQ: Why Are My UIParticles Not Displayed Correctly?
+
+If `ParticleSystem` alone displays particles correctly but `UIParticle` does not, please check the following points:
+
+- [Shader Limitation](#shader-limitation)
+    - `UIParticle` does not support all built-in shaders except for `UI/Default`.
+    - Most cases can be solved by using `UI/Additive` or `UI/Default`.
+- Particles are not masked
+    - `UIParticle` is maskable.
+    - Set `Mask` or `RectMask2D` component properly.
+    - [Use maskable/clipable shader](#how-to-make-a-custom-shader-to-support-maskrectmask2d-component) (such
+      as `UI/Additive` or `UI/Default`)
+- 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 the `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 the 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 the `Auto Scaling` option.
+    - It is recommended to place `ParticleSystem` under `UIParticle`.
+- If `Transform.localScale` contains 0, rendering will be skipped.
+- Displayed particles are in the correct position but too large/too small
+    - Adjust `ParticleSystem.renderer.Min/MaxParticleSize`.
+
+<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.
+
+#### (Unity 2018 or 2019) UV.zw components will be discarded
+
+UIParticleRenderer renders the particles based on UIVertex.  
+Therefore, only the xy components are available for each UV in the shader. (zw components will be discarded).  
+So unfortunately, UIParticles will not work well with some shaders.
+
+#### (Unity 2018 or 2019) Custom vertex streams
+
+When using custom vertex streams, you can fill zw components with "unnecessary" data.  
+Refer to [this issue](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/191) for more information.
+
+<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 the `Mesh Sharing` feature in
+  the [UIParticle Component](#uiparticle-component).
+    - If you don't like the uniform output, consider the `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 a single material, atlasing the sprites, and using `Sprite` mode in the `Texture Sheet Animation` module
+      in the ParticleSystem.
