Create Collider
Generate Collider components.
Parameters
| Parameter | Type | Description |
|---|---|---|
| oneColliderPerObject | Boolean | |
| strategy | ProxyStrategy | |
| maxDecompositionPerMesh (Max decomp. per object) | Int32 | Maximum number of decompositon to generate, per mesh. On a fork for instance: you would put 5: 4 for the spikes + 1 for the base. |
| maxTrianglesPerMesh (Max triangles. per mesh) | Int32 | Maximum number of triangles per output convex collider mesh |
| resolution | Range | Concavity resolution (the higher the more concave). |
| gridResolutionPreset (Mesh quality preset) | GridResolutionPreset | Voxelization quality presets. |
| gridResolution (Quality value) | Int32 | Specify the voxel grid resolution. A setting of 'x' divides the model into roughly x³ voxels. Increasing this value may result in longer processing times and more triangles in the output mesh. |
| boundingBoxType (BoundingBox) | BoundingBoxType |
Additional Information
This function creates a compound collider on an existing or new mesh. Four strategies are available:
Retopology
Use this strategy to create a mesh approximation with a low polygon count for the assigned collider. Read more about retopologizing.
Convex decomposition
Use this strategy to generate a set of convex mesh colliders from the source geometry. This strategy is ideal for advanced physics collision. Colliders are assigned to existing GameObjects.
Specify these parameters:
| Parameter | Description |
|---|---|
| Max decomposition per mesh | The maximum number of convex hulls to generate per mesh. For the gray Gameobject in the illustrated example, the best value is 4 – for the 3 tubes and the base. |
| Max triangles per mesh | The maximum number of triangles per output collider mesh. |
| Resolution | The precision of the mesh collider. High resolutions drastically increase processing time. |
Axis-aligned bounding-box
Use this strategy to create a set of box colliders for each mesh. Colliders are assigned to existing GameObjects.
Initial mesh
Use this strategy to use the existing mesh as a collider.
