Add support for Bezier curves of arbitrary degree.
...
New functions:
bezier = love.math.newBezierCurve(control-points)
degree = bezier:getDegree() -- degree = #control-points - 1
x,y = bezier:getControlPoint(pos) -- pos < 0 => string.sub semantics
bezier:setControlPoint(pos, x, y) -- pos < 0 => string.sub semantics
bezier:insertControlPoint(x,y, [pos = -1])
x,y = bezier:eval(t) -- 0 <= t <= 1
polyline = bezier:render([accuracy = 5]) -- returns a table of points
Example:
function love.load()
b = love.math.newBezierCurve(10,10, 80,400, 380,400, 470,10)
end
function love.draw()
if not curve then -- curve rendering is expensive-ish
curve = b:render()
end
love.graphics.line(curve)
end

Make most love.filesystem functions return nil, err instead of erroring (when used correctly)
...
Note that argument exceptions, for instance, are still thrown as errors.
Also fixes a potential uncaught exception with getSize being called for the optional
size arg in read, now it just uses the ALL constant instead.
File:read no longer opens and closes a file automagically (this was undocumented, and weird)
NOTE: the love.filesystem.lines iterator can still error, but this should only happen in
case there's something really, really wrong (otherwise love.filesystem.lines would've failed
already)
NOTE: love.filesystem.lines still errors, because otherwise you'd get weird errors from the for
loop (namely 'attempt to call nil value') instead of seeing anything useful

Added love.graphics.getRendererInfo(infotype). Useful for creating more informative error reports and advanced debugging.
...
Returned string can be highly system-dependent, so don't rely on its output!
infotype can be "name", "version", "vendor", or "device"

Exposed Geometry:setVertexColors and Geometry:hasVertexColors, to enable/disable per-vertex colors.
...
Vertex colors are automatically enabled if newGeometry or setVertex is called with a color other than 255,255,255,255
2013-04-24 12:04:24 -07:00
3b05ec0635
Geometries now automatically use per-vertex colors when drawing if any vertex has a custom color set, otherwise the constant color is used.
...
Still not a perfect solution, but it works better than before

71317c4359
Add Geometries (replaces Quads).
...
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()
