A create automation with using own programming language, naming “Metal”.
\nPlace a computer, right click, enter code, press save, shift+right click for toggle run.<\/p>\n
Coding:
\nDeclare 2 Systems (System is just like function), “INIT” and “TICK” like that:<\/p>\n
SYSTEM(INIT): START;<\/p>\n
init code here<\/p>\n
END_SYSTEM;<\/p>\n
SYSTEM(TICK): START;<\/p>\n
tick (loop) code here<\/p>\n
END_SYSTEM;<\/p>\n
API:
\nThere is some functions to work with Metal.<\/p>\n
built-in functions:<\/p>\n
MAKE_VAR(VAR_TYPE,$name,start_value); – making a global variable (global variable MUST start with ‘$’, ONLY in INIT)<\/p>\n
MAKE_ITEM_VAR($name,item_id); – making a INT variable by minecraft item number id (ONLY in INIT)<\/p>\n
SET($name,value); – set new value for variable<\/p>\n
ADD\/SUB\/MUL\/DIV($name,value); – operations with variables<\/p>\n
WAIT(ms); – delaying script (ONLY in TICK)<\/p>\n
CONTINUE(); – return to the current System begin (ONLY in TICK)<\/p>\n
RERUN(); – return to the main System of current script (ONLY in TICK)<\/p>\n
EXIT_STACK(); – exit entire stack of System calls and returns to the point of stack start<\/p>\n
RETURN(); – exit 1 System of stack of System calls<\/p>\n
ABORT(); – forcibly terminate current script (Doesn’t turn off computer)<\/p>\n
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<\/p>\n
IF(condition): START; – Base IF operator (closing – “END_IF;”)<\/p>\n
ELSE(): START; – Base ELSE operator (between IF and END_IF)<\/p>\n
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<\/p>\n
MAKE_LOCAL_VAR(VAR_TYPE,#name,start_value); – making a local variable (local variable MUST start with ‘#’) ONLY in 0.0.3+ mod version<\/p>\n
ACCEPT_INVOKES(); – allow invoke non-reserved systems by integrations ONLY in INIT, for 0.0.4+ mod version<\/p>\n
PRINT(args…); – INFO Output (white) ONLY in 0.0.6+ mod version<\/p>\n
WARN(args…); – WARN Output (yellow) ONLY in 0.0.6+ mod version<\/p>\n
ERROR(args…); – ERROR Output (red) ONLY in 0.0.6+ mod version<\/p>\n
end of built-in functions<\/p>\n
Java Functions (registered outside of a Metal):<\/p>\n
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<\/p>\n
CONNECT_LINK_RECEIVER(id,item1,item2); – making a receiver connection (use MAKE_ITEM_VAR variables for two last arguments) ONLY in INIT<\/p>\n
SEND_LINK(id,power); – send power to Create Redstone Link (use with id, used in CONNECT_LINK_SENDER)<\/p>\n
RECEIVE_LINK(id); – receive power from Create Redstone Link (use with id, used in CONNECT_LINK_RECEIVER)<\/p>\n
RANDOM(min,max); – returns random INT between min and max<\/p>\n
RAND(); – returns random DOUBLE between 0.0 – 1.0<\/p>\n
SIN(value); – returns sin of the value (use radians)<\/p>\n
COS(value); – returns cos of the value (use radians)<\/p>\n
TAN(value); – returns tan of the value (use radians)<\/p>\n
SQRT(value); – returns sqrt of the value<\/p>\n
DTR(value); – degrees to radians<\/p>\n
RTD(value); – radians to degrees<\/p>\n
GET_PI(); – returns PI<\/p>\n
MIN(args…); – returns MIN of all arguments<\/p>\n
MAX(args…); – returns MAX of all arguments<\/p>\n
CLAMP(value,min,max); – returns limited value in range<\/p>\n
ABS(value); – returns module of value<\/p>\n
POW(value,pow); – returns exponentiation of the value<\/p>\n
GET_OPS(); – returns completed operations of this script – 0.0.5+<\/p>\n
end of Java Functions;<\/p>\n
Tips:<\/p>\n
ADD,SUB, etc using ONLY in modification of value
\nfor example: <\/p>\n
ADD($x,1); = x += 1;<\/p>\n
In brackets:<\/p>\n
IF($x + 1 > $y): START;<\/p>\n
code<\/p>\n
END_IF;<\/p>\n
And, “: START” is not necessarily, but recommended, you also can use<\/p>\n
SYSTEM(INIT);
\n…<\/p>\n
IF(condition);
\n…<\/p>\n
etc.<\/p>\n
Current variable types: INT, DOUBLE, POWER, BOOL.<\/p>\n
TICK EntryPoint (System) running in the other thread 1000 times per second.<\/p>\n
INTEGRATION:
\nSince 0.0.4 you can call non-reserved systems from Computer Craft mod, its looks like:
\nMetal:
\nSYSTEM(INIT): START;
\nACCEPT_INVOKES();
\nBIND_ARGS_TO_SYSTEM(SUM,#first:DOUBLE,#second:DOUBLE);
\nEND_SYSTEM;
\nSYSTEM(SUM): START;
\nRETURN(#first + #second);
\nEND_SYSTEM;
\nSYSTEM(TICK): START;<\/p>\n
END_SYSTEM;<\/p>\n
CC Lua:
\nlocal metal = peripheral.find(“metal”);
\nif metal then
\nprint(metal.callSystem(“SUM”,5,10)); — output: 15
\nelse
\nprint(“Cannot find Metal Computer”);
\nend<\/p>\n
Since 0.0.5 you can use
\nSYSTEM(NAME,args…): START; instead of BIND_ARGS_TO_SYSTEM<\/p>\n
example:<\/p>\n
SYSTEM(SET_POWER,#f:POWER,#s:POWER): START;<\/p>\n
SEND_LINK(1,#f);<\/p>\n
SEND_LINK(2,#s);<\/p>\n
END_SYSTEM;<\/p>\n
“**” instead of “POW(val,pow);”
\n“%” operator<\/p>\n
Since 0.0.6, in output functions you can use literals, just like that:<\/p>\n
PRINT(~Hello World);<\/p>\n
>> Hello World<\/p>\n
or, with variable:<\/p>\n
MAKE_VAR(INT,$test,150);<\/p>\n
PRINT(~counter: ,$test);<\/p>\n
>> counter: 150<\/p>\n","protected":false},"excerpt":{"rendered":"
