| Parameter | Description |
|---|---|
| sprite | The sprite to extract the polygon shape data from. |
| detail | The detail used when tessellating the sprite outline, in the range [0, 1]. This is only used if the sprite doesn't already have its own PhysicsShape outline(s). This value has the same meaning as the similarly named property in the Sprite Editor. |
| alphaTolerance | The alpha tolerance used to separate the sprite from its background, in the range [0, 255]. This is only used if the sprite doesn't already have its own PhysicsShape outline(s). This value has the same meaning as the similarly named property in the Sprite Editor. |
| holeDetection | Selects whether internal holes should be detected when creating the sprite outlines. This is only used if the sprite doesn't already have its own PhysicsShape outline(s). This value has the same meaning as the similarly named property in the Sprite Editor. |
bool
Returns true if the selected sprite resulted in polygon shapes being created. Returns false if not, in which case the Collider will be set to a default primitive shape.
Create polygon shapes using the selected sprite.
If the selected sprite already has its own PhysicShape(s) defined in the Sprite Editor then that outline will be tessellated into polygon shapes to be used here.
If the selected sprite does not have its own PhysicsShape(s) then a new outline will be created using the additional arguments provided. This takes additional time and in all cases, it is preferred that each Sprite has its own PhysicsShape(s) defined.
NOTE: If PhysicsShape(s) are not available in the Sprite and the additional arguments are used in a player build then the Sprite.texture must have read/write enabled in the importer so it is readable.
