I attached a small example. But as sphyrth sad: This is just one of many solutions.

The basic idea is mostly the same: Save the direction the character is looking in some variable and read it when you draw the image.

I cannot help you with the technical stuff, but I know the trick with the numbers. It is the same trick how one converts binary numbers to decimal numbers and back - just with base 40 and not with base 2. Let say you have three numbers: 0 <= a <= 39, 0 <= b <= 39, 0 <= c <= 39. To convert it into a ...

The problem is that your code will be loaded and executed first and after that love.load() will be called. This means that player in line 15 is not defined yet. Put that piece of code inside love.update().

You could use something like RLua which bind Lua und Ruby together:

RLua is Ruby to Lua bindings library that features nearly complete coverage of Lua C API, seamless translation of Lua and Ruby objects into each other, calling Lua functions from Ruby and vice versa.

It is a really fun game. At first I thought it was too easy, but it gets really hard. The thing I like the most: The reload animation. It is gorgeous. Level 2-7 took really long - I nearly gave up. And then I gave up at level 3-1. I know what I have to do, but it is just too frustrating. I peeked in...

Take a peek at the documentation of 30log:

To include the library you just have to add the following line of code: Have fun

You initialize the snake with one head and four tail elements. All of them in on the same spot. In the first update the head then collides with all four of its tails, triggering the death of the snake with its fourth tail element. You can initialize the snake with 3 tail elements, initialize the sna...

If you call the function playerDeath() in love.update(dt) you initialize a new lstSprites . After creating a new player you jump back into the code line where playerDeath() was called. And there the local loop variable nSprite is still iterating over the old number of #lstSprites . Since there are n...

You should upload your .love file. Then someone can take a look at the source code to find the bug. Just a wild guess: You delete sprites by lstSprites[index] = nil This creates gaps in the table. So the table has the same length before deletion, but one index is emtpy. If you try to access that ind...

Reverse the order of the tail-update in line 31 from for i = #tail, 1, -1 do to for i = 1, #tail do and it will work. In your version the position of an element will be set on the position of the previous element and all tail-elements will be on the same position after the update. And if you know th...
