Nice. You can still remove the use of mainCanvas (that is, setCanvas(mainCanvas), setCanvas(), and draw(mainCanvas)), so having no canvases at all, and draw directly to the screen. You aren't doing anything different with the contents of the canvas except passing them to the screen already, so it's ...

object:anotherFuction1() helper:anotherFuction1(object) As I understand it, the second case is right in being more expensive, as it handles more parameters. In both cases you have a table key query ("anotherFuction1"), but the parameters in the first case are (self,), and in the second ca...

Hi Giuliano, welcome. Here are my impressions: - You don't need to reference the global table _G every time. This is already done for you when you use a name that was declared without the 'local' qualifier. It's a great practice to use "local" for everything, even things declared in the to...

Wow, thanks guys! I've tried to make the d-string parser, but it was always bad, there are too much variations how you can write the same vectors. Ah, mine is very simple and would probably fail too with some SVGs out in the wild. By the way, I was fascinated by your work on parabolas. I was looking...

This is an example script of rasterizing a polygon into a grayscale image (R8 format). So, starting from SVG data, you generate an Image object from it then draw that Image as needed. Depending on the shape and its size, it's a bit lighter to have it described as SVG data than as a PNG file in your ...

Wow, you're right. Thanks for the correction. I don't know why I said all of that, when a few days ago I had read the Löve source code and seen how it differentiates the possible uniform types (int, float etc), and used int in a shader myself... The OpenGL wiki does list more types that should be av...

Try self:withinCols(5) so the sugar becomes FallingSand.withinCols(self, 5).

The colon syntax is explained in here (the entire PIL e-book is useful btw): https://www.lua.org/pil/16.html

Unorm16: according to this answer , on older OpenGL versions all data types are mapped to floats. So in your case, it would be a vec2 indeed. In the OpenGL wiki it says that there are other GLSL data types like int, uint, ivecn, uvecn and dvecn, so I think that after some GLSL version those new typ...

I'm in the same boat, in that I haven't tried the Löve audio system yet. What I'd do is make a folder with a main.lua inside it and treat it like a sandbox, testing all kinds of stuff. You mentioned that Banjo Kazooie style of speech, I think there are only two ways: playing the same source over and...

Using a flat array of attributes set by pointer index timed a bit faster than using an array of structs. But using structs leads to less cumbersome code, as instead of "myAttributes[vertexOffset + attributeOffset] = value", you'd do "myVertex.attribute = value". So unfortunately ...
