If PhysFS 2.1-alpha is used and a directory is symlinked, isDirectory will return false (whereas it will return true when PhysFS 2.0 is used.) exists will return true in all cases.
addListener takes a function, and names of events that will trigger the function when they're processed inside love.event.poll or love.event.wait. When the given listener function is called, the name of the event as well as all of the event's arguments are passed to the function.
If addListener is called multiple times with the same function and events, it will not add the function more than once.
removeListener takes a function and removes it from all events it was previously added to.
The basic APIs are:
video = love.graphics.newVideo("myvideo.ogv")
love.graphics.draw(video, ...) -- Video objects are Drawables.
video:play(), video:pause()
video:getDuration(), video:tell(), video:rewind(), video:seek(seconds)
video:getSource()
video:getWidth(), video:getHeight(), video:setFilter(min, mag)
More advanced APIs include video:setSource(source), video:getStream(), and videostream:setSync.
To use a custom pixel shader when drawing a Video, call the new TexelVideo(texcoords) function instead of Texel(texture, texcoords) in order to get the pixel colors of a video frame.
The new versions of the functions are only used if LuaJIT's JIT compiler is enabled.
Those functions are often combined with ImageData:mapPixel or ImageData:setPixel, which also have LuaJIT FFI versions in 0.10.0 - so without JIT-able implementations of the math functions, the FFI code in the ImageData methods would not be JIT-compiled and would end up taking up to 10 times as long to execute compared to the non-FFI versions in 0.9.2.
- Type names for love's Lua objects are specified as an argument to luax_register_type, rather than being statically defined in an array.
- luax_register_type takes a variable number of method array arguments, for registering superclass methods without copying them into the subclass' method array.
Also removed most of the header declarations for wrapper functions.
Each sprite in a SpriteBatch has 4 vertices in the following order: top-left, bottom-left, top-right, bottom-right. The index returned by SpriteBatch:add (and used by SpriteBatch:set) can be multiplied by 4 to determine the first vertex in a specific sprite.
