ParticleEffectForUGUI === This plugin provide a component to render particle effect for uGUI in Unity 2018.2+. The particle rendering is maskable and sortable, without Camera, RenderTexture or Canvas.

Please see [RELEASE NOTE ](https://github.com/mob-sakai/ParticleEffectForUGUI/blob/master/CHANGELOG.md) <br><br><br><br> ## Description  This plugin uses new APIs `MeshBake/MashTrailBake` (added with Unity 2018.2) to render particles by CanvasRenderer. You can mask and sort particles for uGUI without Camera, RenderTexture, Canvas. Compares this "Baking mesh" approach with the conventional approach: (This scene is included in the package.) |Approach|Good|Bad|Screenshot| |-|-|-|-| |Baking mesh<br>**\(UIParticle\)**|Rendered as is.<br>Maskable.<br>Sortable.<br>Less objects.|**Requires Unity 2018.2+.**<br>Requires UI shaders.|<img src="https://user-images.githubusercontent.com/12690315/41765089-0302b9a2-763e-11e8-88b3-b6ffa306bbb0.gif" width="500px">| |Do nothing|Rendered as is.|**Looks like a glitch.**<br>Not maskable.<br>Not sortable.|<img src="https://user-images.githubusercontent.com/12690315/41765090-0329828a-763e-11e8-8d8a-f1d269ea3bc7.gif" width="500px">| |Convert particle to UIVertex<br>[\(UIParticleSystem\)](https://forum.unity.com/threads/free-script-particle-systems-in-ui-screen-space-overlay.406862/)|Maskable.<br>Sortable.<br>Less objects.|**Adjustment is difficult.**<br>Requires UI shaders.<br>Difficult to adjust scale.<br>Force hierarchy scalling.<br>Simulation results are incorrect.<br>Trail, rotation of transform, time scaling are not supported.|<img src="https://user-images.githubusercontent.com/12690315/41765088-02deb9c6-763e-11e8-98d0-9e0c1766ef39.gif" width="500px">| |Use Canvas to sort|Rendered as is.<br>Sortable.|**You must to manage sorting orders.**<br>Not maskable.<br>More batches.|<img src="https://user-images.githubusercontent.com/12690315/41765087-02b866ea-763e-11e8-8c33-081c9ad852f8.gif" width="500px">| |Use RenderTexture|Maskable.<br>Sortable.|**Requires Camera and RenderTexture.**<br>Difficult to adjust position and size.<br>Quality depends on the RenderTexture's setting.|<img src="https://user-images.githubusercontent.com/12690315/41765085-0291b3e2-763e-11e8-827b-72e5ee9bc556.gif" width="500px">| <br><br><br><br> ## Demo [WebGL Demo](http://mob-sakai.github.io/ParticleEffectForUGUI) <br><br><br><br> ## Usage 1. Download ParticleEffectForUGUI.unitypackage from [Releases](https://github.com/mob-sakai/ParticleEffectForUGUI/releases). 1. Import the package into your Unity project. Select `Import Package > Custom Package` from the `Assets` menu. 1. Add particle system to canvas. 1. If you want to mask particles, set the "UI/UIAdditive" shader to material. 1. Add `UIParticle` component to particle system from `Add Component` in inspector.  1. Enjoy! ##### Requirement * Unity 2018.2+ (Tested in Unity 2018.2b9) * No other SDK are required <br><br><br><br> ## Development Note #### BakeMesh API has a issue! See [this issue](https://issuetracker.unity3d.com/issues/bakemesh-slash-baketrailsmesh-crashes-if-update-jobs-are-running). `UIParticle` avoids the issue, but the rendering result lags one frame. Please vote the issue to improve `UIParticle`! <br><br><br><br> ## License * MIT * © UTJ/UCL ## Author [mob-sakai](https://github.com/mob-sakai) ## See Also * GitHub page : https://github.com/mob-sakai/ParticleEffectForUGUI * Releases : https://github.com/mob-sakai/ParticleEffectForUGUI/releases * Issue tracker : https://github.com/mob-sakai/ParticleEffectForUGUI/issues * Current project : https://github.com/mob-sakai/ParticleEffectForUGUI/projects/1 * Change log : https://github.com/mob-sakai/ParticleEffectForUGUI/blob/master/CHANGELOG.md
