[SOLVED] Using intersection of stencils

[msilvestro]

Hi everybody!
I'm trying to draw a tiled ground, but I want it to be a circle of radius r. So, I first drew a square with sides of 2*r of length, and then I applied a stencil of a circle of radius r with the same center of the square, and everything worked very well.
My problem is this: what can I do if I want, let's say, a circular sector of the circle with inside the tiled ground, what can I do?
With stencils, if I add a triangle in the stencil function (with already the circle), I get the union of the shapes, but what if I want the intersection of them?
Is that possibile with stencils? Or maybe I have to study the canvases to achieve this?
Thanks for the help!

Did you try setting a stencil while drawing a stencil?

Do you mean something like this?

Code: Select all

triangle = function()
	love.graphics.polygon("fill", xc, yc, 0, 600, 300, 0)
end
groundCircle = function()
	love.graphics.setStencil(triangle)
	love.graphics.circle("fill", xc, yc, r, 100)
	love.graphics.setStencil()		
end

If yes, it didn't worked... I don't know what to do exactly!

You can draw a circular sector with love.graphics.arc. And if you need a more complicated shape you can always make a polygon of the shape and use this as a stencil.

Oh thanks, I didn't remembered there was such a function!
