slick v1.0.1

• Fix slick.world.add to return slick.entity instance representing item instead of the slick.entity type.

slick v1.0.0

🚀 Here we go!

No differences in slick from v1.0.0.

1. Moving forward, breaking changes will cause a bump in the major version number
2. Significant non-breaking feature additions will bump the minor version number.
3. Bug fixes, optimizations, and minor additions to existing features will bump the minor version number.

Thanks to everyone who tested and gave feedback! LET'S GO!

slick v0.1.7

• Add slick.newMeshShape
• Make normals direction consistent regardless shape-shape evaluation order and other cases. +Y will always be pointing down (assuming +Y is down in the game, e.g., default LÖVE behavior) and -Y will always be pointing for circle-polygon, polygon-circle, polygon-polygon, and circle-circle collisions
• Tweak default epsilon

slick v0.1.6

• Add optional tag field to slick.collision.shapelike instances. This tag field can be populated by passing in a slick.tag (created by slick.newTag) to all slick.collision.shapeDefinition constructors. See README.md for more information.
• Make slick library paths look a little nicer in the traceback when slick is in a subdirectory.
• Fix greedy insert in quad tree node expand causing duplicate inserts and crashes.
• Fix broken demo after breaking change. Whoops!

slick v0.1.5

A little bigger than usual... Mostly fixing cross and adding bounce with supporting work and documentation.

Major user-facing changes

• Fix bug where all responses were treated as slide.
• Fix cross response handler.
• Add bounce response handler.
• Update demo to include bouncing bubble.
• Breaking change: rename slick.newBoxShape to slick.newRectangleShape. This was leaking an implementation detail and also causing inconsistent naming (e.g., with slick.world.queryRectangle)
• Formally document slick.worldResponseFunc
• Improve documentation for slick.worldQuery and slick.worldQueryResponse

Internal changes

• Changes to behavior of slick.worldResponseFunc
  • Add optional slick.worldQueryRespone return value. If a response handler returns a value other than nil, then slick.world.check will immediately attempt to handle the returned slick.worldQueryResponse without causing a bounce. See documentation updates.
• Refactor to how pooled slick.geometry.point are handled in a slick.worldQuery. Now, the slick.worldQuery can automatically pool objects of a slick type (i.e., slick.geometry.point in this case) across all slick.worldQueryResponse children. Before, each slick.worldQueryResponse pooled its own slick.geometry.point specifically for contact points. Now these point instances are pooled across responses.
• Support moving an instance belonging to one slick.util.pool to another slick.util.pool. This is used by slick.worldQuery when move-ing a slick.worldQueryResponse from one query to another; any pooled extra fields will be transparently moved as well.

slick v0.1.4

• Fix precision issues with clipper.
• Fix incorrect logic when querying line segments in a quad tree.
• Add optional epsilon to line segment and point queries in a quad tree.
• Add simple triangulation and clipping API.

slick v0.1.3

• Add clipper API.
• Fix crash with quad tree point query API.

slick v0.1.2

• Fix data missing in quad tree when straddling the border after an automatic expansion
• Small fix to slick.world.optimize - the method rebuilt the quad tree but didn't update the bounds of the root node!
• Fix polygon-circle edge case when contact normal as axis aligned causing slight penetration and jitter.

slick v0.1.1

• Improve documentation.
• Fix bug causing potentially overlapping polygons in polygonization in certain situations.
• Add maxPolygonVertexCount to slick.geometry.triangulation.delaunayTriangulationOptions. This allows putting an upper limit on the max vertices in a polygon generated during polygonization. Useful if you're using the polygonization e.g., with Box2D.
• Add slick.world.optimize method to optimize quad tree in-place.

If there's no more bugs, then the next release will be v1.0.0!

slick v0.1.0

slick alpha release!
