love.graphics.polygon.isInside(x, y)

What about adding a function to each shape provided by Löve to check whether a given (x,y) is inside? Would be tremenduously cool ! ;)

Re: Share your favourite helper functions

I've found that building up a library of helper functions can really speed up programming and debugging in Löve/Lua. I've called them "helper functions" in the title, but basically any techniques, modules, functions etc. that you use a lot and have saved you a lot of time would be great. ...

Re: löve time: how does it get precision?

Thank you all, very helpful. I'll have a look at the SDL method and luasocket too (which I have never used).

Re: Tables for Dummies

That's a great idea, Denis. Well written tutorials are always welcome. Anyway, I tend to think that most people don't actually take enough time to search. Concerning tables, for instance, here are some great starting point: Pil - Lua-Users Tables Tutorial - Gts Stolberg - Litt's Lab - MUSHClient tu...

Re: Tables for Dummies

Can someone explain me tables "for Dummies" style? Thanks! I was about to propose starting a tutorial on lua tables and data structures, after noting many isssues on this forum related directly or indirectly to table usage (and meaning). I would start with my practices and views, then eve...

[solved] löve time: how does it get precision?

In Lua (afaik), one only gets the C-standard , 1-second precision time. How do we get precise time in Löve (via dt)? And how precise is it (guaranteed to be)? EDIT: if the code to get that (C, I presume) is accessible, I would really appreciate a pointer to it (I planned to write a little hook to ge...

Re: weird bug with lua (5.2) table.pack & table.unpack

LÖVE currently only links against Lua 5.1. If you see Lua 5.2 stuff, you might have a LÖVE linked against LuaJIT with 5.2 compatibility enabled. The Arch Linux package links against LuaJIT, but I don't know if they enabled the 5.2 stuff. See _VERSION (and jit for LuaJIT) to be sure. I don't know if...

[solved] weird bug with lua (5.2) table.pack & table.unpack

Hello, These 2 funcs (pack new to 5.2, unpack move to field of table) work fine by me in general. However, sometimes, lua simply does not find them (also under aliases without the 'table.' prefix). But just sometimes . This seriously gets on my nerves because I cannot find the logic of the errors. A...
