Re: Is LÖVE a framework, API, or engine?

An engine that provides an API that serves as a framework for 2D games. So, all three to some degree.

Re: Custom types in Lua

Personally if I know that (for example) a function parameter is going to be a class in the form of a table then I will check its type, if necessary, by looking at its metatable, e.g.: if getmetatable(object) == WhateverClass.Metatable then ... end If you use a third-party library for OOP then it may...

Re: Library Version Control

~/my-game $ git submodule foreach git pull origin master Alternatively I think you get the same effect with this: $ git submodule update --remote A trivial improvement as far as "number of keys you have to press" is concerned. But if you ever have submodules that either pull from somewhere besides ...

Re: Remove value in table when a body gets destroyed?

You need to give table.remove() the numeric index for the sub-table you want to remove. You could do this by looping through using ipairs() instead of pairs(), and when you find the unit you want to remove then you'll have the index to give to table.remove(). At which point you should break out of t...

Re: Can I mark table as userdata?

Robin is correct. You can have userdata behave like a table in your Lua code by defining pointers to functions to act as table functions/methods, and by defining a metatable to affect that userdata. Chapter 29 of "Programming in Lua 3rd Ed" covers this, as I'm sure the older editions do as well, but...

Re: Emacs Minor Mode for LÖVE

Sorry, but I can't replicate the error. Please double-check that the minor mode is enabled via 'M-x love-minor-mode', since it adds a hook to lua-mode to automatically enable itself when it thinks you're editing a file of LÖVE-related code, but the method it uses is not bullet-proof, so it may be fa...

Re: Having trouble using require and tables at the same time

Sorry, but could you be a little more specific about what you’re trying to do? I assume you meant your “own modules […] needs to save data.” Whatever the case, if you would please post the code in queston it would make it much easier to help you resolve the problem.
