Previously, calling e.g. love.graphics.getFont() 10,000 times would retain the object 10,000 times (and release it 10,000 times when the Font object was garbage-collected in the Lua state.) Now it will only retain it once and release it once.
luax_pushtype keeps the object in a weak table and checks the table before creating a new userdata, so it re-uses the object's existing wrapper userdata if it can, whenever the object is pushed to Lua.
This fixes some subtle issues with love objects, where using them as keys in tables would not always work as expected (https://love2d.org/forums/viewtopic.php?f=4&t=39398&p=112388#p112415). It also decreases the amount of new Lua objects created, saving the garbage collector some work.
A Geometry is a collection of vertices describing a non self-intersecting
(simple) polygon. In addition to screen coordinates, the vertices have
attributes for texture coordinates (s,t) and color (r,g,b,a).
It can be used as a quad, to display distorted images, or anything in between.
Added:
^^^^^^
-- geometry from table, where table has the format:
-- info = {
-- {x,y, s,t, [r = 255, g = 255, b = 255, a = 255]}
-- {x,y, s,t, [r = 255, g = 255, b = 255, a = 255]}
-- ...
-- }
geom = love.graphics.newGeometry(info)
-- convenience wrapper for quads (same as before)
geom = love.graphics.newQuad(x,y, w,h, sw,sh)
-- retrieve vertex i (1-indexed)
x,y,s,t,r,g,b,a = geom:getVertex(i)
-- set vertex i (1-indexed)
geom:setVertex(i, x,y, s,t, [r,g,b,a])
-- flip geometry
geom:flip(x, y)
Renamed:
^^^^^^^^
love.graphics.drawq() -> love.graphics.drawg()
Removed:
^^^^^^^^
quad:setViewport()
quad:getViewport()
The audio module was not really stable in 0.6.0, it takes very little messing around to cause OpenAL to do horrible things. It should now be much more stable,
and you *should* be able to play/stop/pause/resume/rewind/loop like a madman without disasters. Seek and tell, however, are still not tested and verified for
all decoders, but that's less important. Also, all objects now have object:type() and object:typeOf(), which returns the type name of the object,
and checks whether an object is of a certain type, respectively.
