I need help with loops,functions,making a game with the things I know.

Be a bit more specific...?

Loops:

while (Condition) do
	COMMANDS
end

for (Variable Declaration, COondition, Callback = +1) do
	COMMANDS
end

do
	COMMANDS
while(Condition)

Functions:

function Foo(local bar)
	bar = bar + 5;
	return bar
end

print(Foo(5)) --Prints 10

Kinda short, but I hope it helps :)
