name = "Peter"
print("Hello "..name)
-> Hello Peter
this format is: "command param1 param2 param3..."
(parameters separated with spaces)
how you do it: you simply join the "strings" and variables with .. (.. is an operator to concatenate strings. you use + to add two numbers but .. to "add" two strings)
imagine the variable values are:
effect=1
x=2
y=3
p1=4
p2=5
r=6
g=7
b=8
then this
parse("effect "..effect.." "..x.." "..y.." "..p1.." "..p2.." "..r.." "..g.." "..b)
would result int:
parse("effect 1 2 3 4 5 6 7 8")
a valid command with parameters in the right format so that CS2D can execute it. that's it.
it's important that you add spaces. one space behind the command itself "effect_" and of course one space between all parameters "_". otherwise you would end up with: parse("effect12345678") which is nonsense. CS2D doesn't understand it.
hope that helps to understand the idea.
common mistakes:
many idiots use .."".. to attach an empty string to the string. it changes NOTHING and is always 100% pointless. it's like adding 0 to a number. it makes no difference. we use .." ".. to add WHITESPACES, but "" doesn't add anything because it's an empty string. " " and "" = huge difference!
some people add a space to the end .." ". this also makes no difference. CS2D doesn't care if the command ends with a space or not.
oh and you actually don't have to care about all this if you include and use wrapper.lua
(but remove the map function from it! it's a bug) edited 1×, last 17.09.11 09:53:33 am
It's useful if you want to include double quotes in your string.

mystring='my quotes "lol" are here'
It works with patters as well...

mystring="my quotes \"lol\" are here"
