function binary_operation(operation_func, operand1, operand2)
return operation_func(operand1, operand2)
end
function add(o1,o2) return o1+o2 end
print(binary_operation(add,3,4))
return operation_func(operand1, operand2)
end
function add(o1,o2) return o1+o2 end
print(binary_operation(add,3,4))

I know ( interesting is that posting in old threads needs longer cool down - 90 seconds), but I noticed now what Lee posted and just wanna ask. It's not a crime, is it?

Im sorry that im reviving old thread, but here is a some LUA tips & tricks from me
CS2D Related:
Spawn player without any weapons at all
And some general LUA tricks:
Getting LUA filename that call the function
Info: Because debug library still exist in CS2D, this LUA also can be used on Counter-Strike 2D. It just uses a debug.traceback() function
Creating a error

On the main thread, this is the worse random number generator I've seen.
Unless you're going to use it for your cryptographic needs. Then it's perfect.

lol yeah, now that i know more about random numbers...that "truly" random number generator is absolute ass wipe. at least in c++, if you try to get reseeded numbers every time, the numbers will actually just be incrementing slowly instead of being random. this is worse than just seeding it once. you actually have to code this and run it to see what im talking about
will code for food

Buildings in Cs2D are nothing more than dynamic objects. Like images. That means you can manipulate them using imagepos etc.

Since everyone was using command line functions to know the operating system, I though it'd be better to post this easier way.

Tired of having undefined variables returning
I'm not here to debate language decisions; but if I were, I would definitely rank this as one of the most egregious issue with Lua. However, we can fix this!
This line tells Lua to route all undefined global indexing (aka variable resolution for global variables, which is the fallback routine in case local variable resolution fails) through our own function (__index), which just raises an error.

s everywhere? Are you suffering from spats of unfotunate speeling mistekes? Then you'll understand how annoying it is to track down one small typo within your goliath of a codebase. Seriously, that's probably the solution to about 30% of all of the questions that are asked in this forum.I'm not here to debate language decisions; but if I were, I would definitely rank this as one of the most egregious issue with Lua.
