bump.lua changelog

v3.1.7

  • Fixes rare edge case which was triggered sometimes when two rects shared one corner and one of them moved (#33)

v3.1.6

  • Fixes queryRect accepting rectangles with negative dimensions without raising an error

v3.1.5

  • Fixed a typo inside the bounce code

v3.1.4

  • bump.lua was declaring '_' as a global variable by mistake. Added automated tests to prevent other global vars in the future

v3.1.3

  • Fix floating-point issue when using coordinates like 100.1298374892437, by adding a 10^-10 delta margin in some operations
  • Add and remove less stuff when updating an item

v3.1.2

  • Add world:getItems and world:countItems

v3.1.1

  • Bugfix in rect_detectCollision where goalY was not correctly initialized

v3.1.0

  • The filter parameter of world:move, world:check and world:project now has the signature filter(item, other) instead of filter(other).

v3.0.0

  • Renamed world:move to world:update
  • world:move() now implements a basic collision-resolution algorithm - no need for the user to do the "complex loops" he needed to use in 2.0.x
  • Collisions no longer have methods. Instead, filter now returns "the type of collision", and "move" handles that internally. The collisions are now "plain tables", which are returned by world:move after all the collisions have been dealt with.
  • Added a new type of collision: cross, for when it's good to know that a collision happened but item's trajectory should remain unaltered
  • world:check() does the same thing as world:move, except without calling world:update. Useful for planning/studying alternatives without moving things.
  • world:project() now does more or less what word:check() did in 2.0.0. It's a key method for collision resolution.
  • world:getRect now returns 4 integers instead of a table
  • Collision detection is handled by the function rect.detectCollision.
  • The rect module is now available to the user.
  • It is possible to add new response types to the world

v2.0.1

  • Added world:hasItem(item)

v2.0.0

  • Massive interface change:
    • moved the state to worlds
    • Only 1 element can be "moved" at the same time
    • Introduced the concept of "Collision methods"
