Testing the new things in 0.9.0

But love.window.isVisible works properly? ffffuuuuu

EDIT: I think I found the issue, but the fix will probably be a bit hacky... oh well.

Yep, love.window.isVisible works just great, sorry!


Here's an example of creating a SoundData and a Source from a base64 encoded string, and a couple of new SoundData methods:

Code: Select all

function love.load()
	data = 'RXh0ZW5kZWQgTW9kdWxlOiBzb2x... etc. Check out the .love file to test it!'
	filedata = love.filesystem.newFileData(data, '.xm', 'base64')
	sounddata = love.sound.newSoundData(filedata)
	source = love.audio.newSource(filedata)
	source:play()
end

function love.draw()
	love.graphics.print('Number of samples: '..sounddata:getSampleCount(), 0, 0)
	love.graphics.print('\nDuration: '..sounddata:getDuration()..' seconds', 0, 0)
end

Well, Shaders seem to be well & happy.

Font filtering and love.graphics.printf!

Code: Select all

function love.load()
	love.window.setMode(650, 100)

	font = love.graphics.getFont()
end

function love.draw()
	-- The filter style of Fonts can be set.
	-- When setFilter is given one argument, it is used when the object is either magnified or minified.

	font:setFilter('nearest')

	-- love.graphics.printf has "justify" align mode and transformation parameters.

	love.graphics.printf(
		'This is a test!',
		10, 10, -- position
		200, -- width
		'justify', -- align mode
		0, -- rotation
		3, nil, -- x and y axis scale (y axis defaults to x axis)
		0, 0, -- offset
		-0.3, 0 -- x and y axis shear
		)

	font:setFilter('linear')

	love.graphics.printf(
		'This is a test!',
		10, 50, -- position
		200, -- width
		'left', -- align mode
		0, -- rotation
		3, nil, -- x and y axis scale (y axis defaults to x axis)
		0, 0, -- offset
		-0.3, 0 -- x and y axis shear
		)
end

FYI the 'justify' AlignMode is pretty broken right now. It needs major fixing/rewriting before it'll match real justified alignment.

[quote="Santos"]So I thought it would be cool to have a thread when 0.9.0 is released to talk about and show examples of the new functionality, but then I thought, why wait, it could be useful to talk about what's new now so it can be documented and tested with the nightly builds.

Just wondering where you live - that the nights are so long.
The last 'nightly build' was on June 24.

Cursors!

I'm wondering, why do new Cursors have to be created from CursorTypes rather than passing the CursorType to setCursor, since only one style of Cursor can be made from each CursorType? Something like this doesn't seem to make sense:

Code: Select all

cursor1 = love.mouse.newCursor('arrow')
cursor2 = love.mouse.newCursor('arrow')
