Re: Coordinates for lines vs points (and pixel grid alignment for points)
LÖVE's coordinate system is rooted in the upper-left corner of the screen, which is at location (0, 0) [...] the location (0, 0) aligns with the upper-left corner of the pixel as well, meaning that for some functions you may encounter off-by-one problems in the render output when drawing 1 pixel wi...

Re: Coordinates for lines vs points (and pixel grid alignment for points)
In the end, it doesn't matter how the underlying hardware works. Oh yes, yes it does x). The best APIs are those that reflect how the hardware work, because they build knowledge of what exactly is going on physically. See what Gump said, he understood exactly what I meant. To be clear, this wasn't ...

Re: Coordinates for lines vs points (and pixel grid alignment for points)
In the end, it doesn't matter how the underlying hardware works. The only thing which matters is the contract that the API offers. And for a 2D platform such as Love2D, specified pixel locations should *absolutely* be accurate because they should directly map to an underlying surface, for example an...

Re: Coordinates for lines vs points (and pixel grid alignment for points)
Hello, What I pointed out is that I'm not getting the same behaviour for all primitives. If you look at the picture I posted, passing the same x coordinate to points() and line() does not result them in starting at the same horizontal pixel. In my example, I set the line drawing mode to "rough&...

Coordinates for lines vs points (and pixel grid alignment for points)
While doing some tests, I noticed that if I drew lines and points with the same coordinates, I couldn't get them aligned. For example, calling: love.graphics.points(10, 1) love.graphics.line(10, 2, 15, 2) will result in the point being drawn one pixel before the line, as if it had been issued at (9,...
