Unity Collider Optimizer
Optimizes Mesh & Polygon colliders in Unity.
Polygon Collider Optimizer
| Original Sprite | Unity Polygon Collider | Optimized Polygon Collider |
| Path Count | 213 paths | 23 paths |
The tool uses a C# implementation of the Ramer Douglas Peucker Algorithm to smooth the polylines and reduce the number of paths created by a Polygon Collider in Unity.
Performance Comparison
You can run this test on your machine by cloning the project and going to the Polygon Collider Optimization Test scene in Unity.
Usage
- Download the
collideroptimizationpackage_2d_v004.unitypackagepackage from the Releases. - Import all the assets from the package in your unity project.
- Attach the
PolygonColliderOptimizer.csscript on your 2D sprite. - Adjust the
optimizationFactorto control the amount of optimzation you need.
Mesh Collider Optimizer
| Original Mesh | Unity Mesh Collider | Optimized Mesh Collider |
| Triangles Count | 9132 tris | 2416 tris |
The tool uses the Computational Geometry Unity Library by Erik Nordeus 🐐 to perfrom the Quadric Error Metrics simplification on the shared mesh of the mesh collider.
Performance Comparison
You can run this test on your machine by cloning the project and going to the Mesh Collider Optimization Test scene in Unity.
Usage
- Download the
collideroptimizationpackage_3d_v004.unitypackagepackage from the Releases. - Import all the assets from the package in your unity project.
- Attach the
MeshColliderOptimizer.csscript on your 2D sprite. - Choose the connecting mode between Fast, Precise, and No.
- Adjust the
optimizationFactorto control the amount of optimzation you need. - Choose the mesh style to be Soft, Hard or both.
- Warning: Choosing the "Fast" mode would likely lead to errors, Precise mode is recommended for most of the meshes.
Updates
v004
- Added the functionality to save and load the optimized colliders as assets.
- Fixed the refresh bug.
Contribution
Contributions to the project are welcome. Currently working on converting the QEM algorithm to a coroutine to stop the main Unity thread from freezing.
Known Bugs
If a prefab is made out of a gameobject having Polygon Collider Optimizer, it keeps refreshing itself.[FIXED]- Choosing Hard Edge Mesh Style decreases the number of triangles but induces additional vertices (doesn't affect the performance).
