@Linkpy, your formula for the determinand is wrong. Should be det = @matrix[1] * (@matrix[5] * @matrix[9] - @matrix[6] * @matrix[8]) det -= @matrix[2] * (@matrix[4] * @matrix[9] - @matrix[6] * @matrix[7]) det += @matrix[3] * (@matrix[4] * @matrix[8] - @matrix[5] * @matrix[7]) Also, when composing th...

It's curious because SFML use 4x4 matrix, using it like a 3x3 for 2D operations... I don"t understand :crazy: My guess is they uses 4x4 matrices in order to apply perspective. If you are interested (as I think) in 2D operations, augmented 3x3 matrices suffice. However, please keep in mind that...

It's somewhat odd that so may developers devised a similar project structure. I've also seen very badly unstructured projects that works perfectly, but an organized one put the mind at ease when working on it. Personally I'm adopting something like the following structure +- root +- assets +- data <...

The "formula" is simply to apply the matrix operations by yourself. I don't think the trasformation matrix can be retrieved from the graphics subsystem.

Give the canvas destination rectangle (or, at least, the maximum line length in pixels) I would break the texts on whitespaces. Then, iterating the words I would build every single line of text, measuring the line width. Upon reaching the maximum length, store the current line and start new one. loc...

I'm stupid.

It should also be

Code: Select all

function test.new(x)
    local self = {}
    setmetatable(self, test)
    self.x = x
    return self
end

in my opinion. There's no point in using the

Code: Select all

specifier in the allocator.

I opted for a similar approach, in some projects, but using a queue of closures with priority. That way I simply enqueue the drawing snippets without the need to define a specification format to be interpreted.

So to recap this - default (strong) tables are collected only when there is no more references to them (and collection cycle happens), and weak tables can be collected on next collection cycle. Am i right? It isn't the table the object of the garbage-collection, but the objects/functions/whatever t...

However, developer who actualy is concerned about this is not going to use GC-d language for perfomance-sensitive applications. That is exactly my point. If I'm going to be real concerned about garbage-collector related issues, and I'm working on a performance-critical piece of software, and I can ...

i think it is going to be way better if i lift the burden off garbage collector's shoulders as much as i can, since it allows to minimize things like fps spikes during collection cycle etc. I have the exact opposite opinion. :) The garbage-collector exists with the sole aim to relieve us, the progr...
