love.graphics.setStencil not applying over canvases?

[davisdude]

It came to my attention that, when paired with STI, Brady, my camera library, drew certain portions that should not have been drawn. When I use love.graphics.setScissor, it worked, though.

It works regularly when I comment out the lines from STI pertaining to drawing to a canvas, but not with the canvas.
Is this the intended result? Am I missing something?

(.love's are over on this thread if you're interested)

What .love you are referring to: MV Platformer or BWE?
In both cases setShape function is never called.
Tried MV Platformer with LÖVE 0.10.0 (adapted several functions including stencil related) and it works (all is clipped to rectangular region in the top left corner).
If this is not what is needed then how result should look like? Or is this wrong .love files?

[davisdude]

Can confirm with 0.10.0 (and proper porting) it works as expected. Does NOT work with 0.9.2.

You can use both:
MV Platformer is demonstrating the problem.
BWE comments out lines in STI that set canvases, and it works as expected.

It seems that setting / unsetting canvases cancels any defined stencils in 0.9.2:

Code: Select all

local lg = love.graphics
local canvas

function love.load()
	canvas = lg.newCanvas(800, 600)
end

function love.draw()
	lg.setStencil(function() lg.rectangle("fill", 100, 100, 200, 200) end)

	lg.setCanvas()

	lg.setColor(0, 100, 0)
	lg.circle("fill", 150, 150, 100)
end

Yeah, that's what I was noticing. Is this intended?

[arampl]

Oh, I've thought question was about problems inside .love.

Stencils are effectively per-Canvas in all versions of LÖVE. The new stencil APIs in 0.10.0 make it a bit more obvious/explicit.
