DATA TYPES

Type	examples	examples	examples	examples	examples	examples
bool	true	false
number	0	123.456	-5
string	"asd 134"
var	string	number	function	var	bool	table
function	pos(1 2 a)
symbol	!	(nil)	? (username)

VARIABLES

a variable can only be set to 1 thing at time

example	-	-	-	-	-	-
varname	a variable
var_aa =	set variable value
another_var =	"string"	123.54	false	var	function()	symbol
vara = varb	set to another var
vara.b =	set as table
vara.1 =	variable index 1 set, eg in lua: vara[1] (limeted to root variable)
event.msg.item	item from event message
a += 5	add 5
a -= 4	sub 4
a *= 98	multiply
a /= 2	divide
a !=	a = nil (used becaouse you can't set a=nll )

note the character "-" can mess if it is written together another symbol

add a node, could be

node.add(pos( -1 2 34) "default:dirt")

and...

c = 34
a = pos(1 2 c)
dirt="default:dirt"
node.add(a dirt)

you can use "return" to break the currently run

Saving/load

Everthing in the "save" variable/table will be automacly saved and loaded, eg:

save.a="asd"
save.unit_users.singleplayer.lpos=get.pos()

if(save.a=="asd")
..code..
end

Events

Any reasons to the script on the unit is running will be able in the "event" variable, eg: event.type

event	type	channel	from_channel	msg
run by gui	"gui_run"	✖	✖	✖
timer	"timer"	✖	✖	✖
wire	"wire"	✔	✔	✔
digilines	"digiline"	✔	✖	✔
msesecons on	"mesecon on"	✖	✖	✖
meseconns off	"mesecon off"	✖	✖	✖
pipeworks	"pipeworks"	✖	✖	✔ (item,count)

IF

if(a==b)  
	..code..  
endif  

if(1=="asd" or a~=b and 87.3>=c nor a<=3 not "aasd"==!)  
	..code..  
elseif(b==!)  
	..code..  
elseif(b~=a not c<b)  
	..code..  
else  
	..code..  
endif  

FOR LOOP

start_n = 3
end_n = 100
for(start_n end_n)
 ..code...
 next

max loops is 1000, dont use negative values use "break" to breat the loop

REGISTRY FUNCTIONS

was.register_function("name"{  
	info="",			--function description  
	privs={},			--required privileges, eg (kick=true,server=true)  
	action=function(arg1,arg2...)	--function  
		return result  
	end  
})  

was.register_function("name"{  
	packed=true,		--inputs all args as table
	action=function(args)  
		return result  
	end  
})  

REGISTRY SYMBOLS

a symbol are called while calling a function or setting a var

was.register_symbol("#",function(),"info"  
		return result  
	end  
})  

USERDATA

The user's information are stored in the global variable "was.userdata"
but is only able while the function / variables are active.

variable / function	description
was.iuserdata(index)	return indexed active data
was.ilastuserdata()	return last index
was.userdata.data	the active line
was.userdata.index	index of active line
was.userdata.function_name	name of active function
was.userdata.name	user's name
was.userdata.var	all active variabbles
was.userdata.error	crach and send text message
