Something like local mathstr = table.concat(mathtbl) local sum = loadstring("return "..mathstr)() might work. Depending on how trusted this string is, you might not want to do that. If the string came from another player over the network, the other player could send you something like {&q...

Nope. I doubt anyone will have a problem as a result, though.

Shmups all day long. You can probably throw together something about as complex and soul-crushingly difficult as Raiden in a weekend.

If you want to make a shmup with a lot of bullets that aren't of constant velocity (or need to be able to spawn other bullets), I would recommend using the ObjMan and Object classes defined in objman.lua and object.lua. Make an ObjMan when your game starts. Register a function with it that does stuf...

It looks like it just stores a private cache and uses a function decorator to check the cache. Then it returns the cached value or the return value of the function you gave it.

Cool, can you post it?

http://ompldr.org/vOGJqNw/nbml-screenie.png This is a tiny demo of a system for scripting shmups by attaching scripts to bullets and executing them asynchronously. It was inspired by my previous work using BulletML and my huge dislike for scripting things in XML. object.lua provides an API that doe...

It seems like his paddle is bigger than mine.

The edge of my monitor looks similar to the black pixels on the edge of my monitor, so those backgrounds are not the best for me. The look that results from the background becoming the same color as the grid is pretty cool though.

I'm glad that works, but ideally Object::release() would never be invoked on an Object that had already deleted itself. It seems like either something is decrementing count without also incrementing it first or you found a super fun race condition.
