Stipple

[Nixola]

Can you give me the .love that hangs? Anyway, added proper line detection and table input, you can as always find it in the repo (also, in string:sub, you can use -1 instead of #string, -2 instead of #string-1, etc)

Thanks for your offer of help.
Problem I encountered with love.graphics.getLineWidth was actually with my code, not yours.
I was setting the line width in newStipple and not draw so nothing happened when I used love.graphics.setLineWidth in love.draw.
My bad.
Found a simple work around so all happy hear.
Best

Stipple2 is basically my stipple ...)

Are you sure? … look at text in lower left corner.
OK1 I'll step back and let you run with this. My intent was to help, not be obnoxious.
That said, for this bunch you really need a racier name for your library. How about 'stripper',
Then they could require 'stripper'. Best. :>)

Darn! Just can't seem to leave this alone.
Added to my version the ability to use either '11001111111100000000' or '200800000000' for the stipple pattern. Couldn't come up with an easy way to deal with the zeros.
Edit2:Now '2b8h' gives same results as using '11001111111100000000'. Don't know if this feature really helpful.

About the numbers... if you have something like

Code: Select all

001100111111110000

you can put something like:

Code: Select all

022284

The first number is the quantity of ones you have, the second is the quantity of ceros, the third is quantity of ones, and so.
Since you start with one and the sequence starts with cero there are 0 ones and then 2 ceros.

Hope its helps is just an idea

Yes, that could be a nice idea, when I get some time I'll add it to the library (of course, unless I forget to do so). Thanks!

To port this to love 0.9.1 you'll just need to change line 62 from

Code: Select all

lg.drawq(self.img, self.quad, x1, y1, a, lw, 1)

to

Code: Select all

lg.draw(self.img, self.quad, x1, y1, a, lw, 1)

I couldn't find any docs for this so here goes.

First load up stipple.lua using [wiki]love.filesystem.load[/wiki], the return value will be a function that we'll be using to create new stipples.

Code: Select all

function love.load()
	newStipple = love.filesystem.load('stipple.lua')

Next create a stipple using the returned function:

Code: Select all

	stipple = newStipple('1111111100000000')
end

The newStipple only waits for one argument, the stipple pattern in string from, this pattern will be repeated to complete the line.
A 1 is a a cue to draw a pixel whereas 0 is the opposite and does not draw a pixel, this is done per pixel for the given line.

Now you can draw your newly created stipple in love.draw() using a pair of coordinates:

Code: Select all

function love.draw()
	stipple:draw(0,0,love.graphics.getWidth(),love.graphics.getHeight())
end

More stuff, you can use the :next() and :prev() (or :previous()) functions to advance or to backward the patter by one pixel.
Try it out, use the left and right keys to move the patterns, they'll move one pixel every half a second:

Code: Select all

function love.load()
	newStipple = love.filesystem.load ('stipple.lua')
	stipple = newStipple('1111111100000000')
	time = 0
end

function love.update(dt)
	if time > 0.5 then
		if love.keyboard.isDown('right') then
			stipple:next()
		elseif love.keyboard.isDown('left') then
			stipple:prev()
		end
		time = 0
	end
end

function love.draw()
	stipple:draw(0,0,love.graphics.getWidth(),love.graphics.getHeight())
end
