Already seen this, but haven't looked at it closely yet. I really just need to know how to call the Java methods from Lua to get input or render stuff.
after a quick search I found this: http://www.keplerproject.org/luajava/
I have no idea how usable/bug free it is
What it looks like I need to use is the loadLib function. I can't test anything right now (on iPhone) but I'll keep posting if I encounter any trouble.
