A create automation with using own programming language, naming "Metal". Place a computer, right click, enter code, press save, shift+right click for toggle run.
Coding: Declare 2 Systems (System is just like function), "INIT" and "TICK" like that:
SYSTEM(INIT): START;
init code here
END_SYSTEM;
SYSTEM(TICK): START;
tick (loop) code here
END_SYSTEM;
API: There is some functions to work with Metal.
built-in functions:
MAKE_VAR(VAR_TYPE,$name,start_value); - making a global variable (global variable MUST start with '$', ONLY in INIT)
MAKE_ITEM_VAR($name,item_id); - making a INT variable by minecraft item number id (ONLY in INIT)
SET($name,value); - set new value for variable
ADD/SUB/MUL/DIV($name,value); - operations with variables
WAIT(ms); - delaying script (ONLY in TICK)
CONTINUE(); - return to the current System begin (ONLY in TICK)
RERUN(); - return to the main System of current script (ONLY in TICK), REMOVED since 0.0.7
EXIT_STACK(); - exit entire stack of System calls and returns to the point of stack start. REMOVED since 0.0.7
RETURN(); - exit 1 System of stack of System calls, since 0.0.7 can actually return values to SYSTEM call
ABORT(); - forcibly terminate current script (Doesn't turn off computer)
CALL_SYSTEM(name, args...); - call System (max stack size is 16), cannot call Systems-EntryPoints (INIT, TICK), args is ONLY in in 0.0.3+ mod version, since 0.0.7, can return values
IF(condition): START; - Base IF operator (closing - "END_IF;")
ELSE(): START; - Base ELSE operator (between IF and END_IF), since 0.0.7 can be called without "()"
BIND_ARGS_TO_SYSTEM(name, args...); ONLY in INIT, args must be like "#var:INT", setting arguments to system call (CALL_SYSTEM), ONLY in 0.0.3+ mod version
MAKE_LOCAL_VAR(VAR_TYPE,#name,start_value); - making a local variable (local variable MUST start with '#') ONLY in 0.0.3+ mod version
ACCEPT_INVOKES(); - allow invoke non-reserved systems by integrations ONLY in INIT, for 0.0.4+ mod version
PRINT(args...); - INFO Output (white) ONLY in 0.0.6+ mod version
WARN(args...); - WARN Output (yellow) ONLY in 0.0.6+ mod version
ERROR(args...); - ERROR Output (red) ONLY in 0.0.6+ mod version
EVALUATE(str); - calculates the expression, added since 0.0.7
EVAL(code); - executes the code like a new SYSTEM, added since 0.0.7
FUNC((args),{ body }); - Creates a MetalFunction, can be called with .invoke(args), added since 0.0.7
CAUSE_HARD_ERROR(message); - Stops the script, log stack and info to console. added since 0.0.7
WHILE(condition, { body }); Runs while condition is true, added since 0.0.7
FOR(#i,start,end, { body }); Runs from #i = start to end - 1, added since 0.0.7
LIST(TYPE); - Creates a MetalList, elements limit is 1024, added since 0.0.7
SET_CATCH_MODE(); ONLY in INIT, now, some of errors won't stop the script, just log with "Error catched!", added since 0.0.7.
SENDER($name,"item1", "item2"); - ONLY in INIT, makes RedstoneLinker (MetalObject) with sending mode, better than old functional method (CONNECT_LINK_SENDER) added since 0.0.7.
RECEIVER($name,"item1", "item2"); - ONLY in INIT, makes RedstoneLinker (MetalObject) with receiving mode, better than old functional method (CONNECT_LINK_RECEIVER) added since 0.0.7.
MAKE_PROCESS(SYSTEM_NAME); - makes second ticking entrypoint, can be called once. ONLY in INIT. added since 0.0.7.
end of built-in functions
Java Functions (registered outside of a Metal):
CONNECT_LINK_SENDER(id,item1,item2); - making a transmitter connection (for two last arguments recommends use MAKE_ITEM_VAR, id is any value, doesn't used before), ONLY in INIT. NOTE: since 0.0.7 use SENDER($sender,item1name,item2name) instead.
CONNECT_LINK_RECEIVER(id,item1,item2); - making a receiver connection (use MAKE_ITEM_VAR variables for two last arguments) ONLY in INIT. NOTE: since 0.0.7 use RECEIVER($receiver,item1name,item2name) instead.
SEND_LINK(id,power); - send power to Create Redstone Link (use with id, used in CONNECT_LINK_SENDER). NOTE: since 0.0.7 use $sender.send(power) instead.
RECEIVE_LINK(id); - receive power from Create Redstone Link (use with id, used in CONNECT_LINK_RECEIVER). NOTE: since 0.0.7 use $receiver.receive() instead.
RANDOM(min,max); - returns random INT between min and max
RAND(); - returns random DOUBLE between 0.0 - 1.0
SIN(value); - returns sin of the value (use radians)
COS(value); - returns cos of the value (use radians)
TAN(value); - returns tan of the value (use radians)
SQRT(value); - returns sqrt of the value
DTR(value); - degrees to radians
RTD(value); - radians to degrees
GET_PI(); - returns PI
MIN(args...); - returns MIN of all arguments
MAX(args...); - returns MAX of all arguments
CLAMP(value,min,max); - returns limited value in range
ABS(value); - returns module of value
POW(value,pow); - returns exponentiation of the value
GET_OPS(); - returns completed operations of this script - 0.0.5+
end of Java Functions;
Tips:
ADD,SUB, etc using ONLY in modification of value for example:
ADD($x,1); = x += 1;
In brackets:
IF($x + 1 > $y): START;
code
END_IF;
And, ": START" is not necessarily, but recommended, you also can use
SYSTEM(INIT); ...
IF(condition); ...
etc.
Current variable types: INT, DOUBLE, POWER, BOOL. Since 0.0.7 - STRING, OBJECT.
TICK EntryPoint (System) running in the other thread 1000 times per second.
INTEGRATION: Since 0.0.4 you can call non-reserved systems from Computer Craft mod, its looks like: Metal: SYSTEM(INIT): START; ACCEPT_INVOKES(); BIND_ARGS_TO_SYSTEM(SUM,#first:DOUBLE,#second:DOUBLE); END_SYSTEM; SYSTEM(SUM): START; RETURN(#first + #second); END_SYSTEM; SYSTEM(TICK): START;
END_SYSTEM;
CC Lua: local metal = peripheral.find("metal"); if metal then print(metal.callSystem("SUM",5,10)); -- output: 15 else print("Cannot find Metal Computer"); end
Since 0.0.5 you can use SYSTEM(NAME,args...): START; instead of BIND_ARGS_TO_SYSTEM
example:
SYSTEM(SET_POWER,#f:POWER,#s:POWER): START;
SEND_LINK(1,#f);
SEND_LINK(2,#s);
END_SYSTEM;
"**" instead of "POW(val,pow);" "%" operator
Since 0.0.6, in output functions you can use literals, just like that:
PRINT(~Hello World);
Hello World
or, with variable:
MAKE_VAR(INT,$test,150);
PRINT(~counter: ,$test);
counter: 150
OBJECTS:
MetalList: $list.add(value); $list.get(index); $list.getFirst(); $list.getLast(); $list.remove(index); $list.removeFirst(); $list.removeLast(); $list.clear(); $list.size(); $list.maxSize(); $list.hasIndex(index); $list.forEach(MetalFunction);
MetalFunction: $func.invoke(args); $func.getTypes();
RedstoneLinker: SENDER: $sender.send(power); $sender.toggle(active); RECEIVER: $receiver.receive(); $receiver.isActive();
since 0.0.8 variables can be assigned like that:
TYPE $global_var = ...;
TYPE #local_var = ...;
changing:
var++; (increment)
var--; (decrement)
var+=...; (add)
var-=...; (sub)
var%=...; (mod)
var*=...; (mul)
var/=...; (div)
var**=...; (pow)
var=...; (set)
