==What's different in SQF==
__NOEDITSECTION__
* Every command has to end with semicolon.
{{SideTOC}}
* SQF does not have a [[goto]] command anymore.
[[SQF syntax]] has been introduced in {{ofpr}} v1.85 and is the Arma series' main scripting language since. The main differences with [[SQS syntax]] are:
* SQF commands can span several lines if they are enclosed in brackets.
* SQF can return a variable, where SQS cannot.


==Replacing==
* '''[[execVM]]''' is used (instead of [[exec]] for SQS)
* Every command has to end with a semicolon ({{Inline code|;}})
* the following commands disappeared:
** [[goto]]/#label (Note, [[a hash b|#]] is a command in itself in {{arma3}})
** [[exit]] - a partial SQF equivalent can be found in [[exitWith]]
* Line returns do not impact code
* SQF can return a variable, where SQS cannot

Template:SideTOC SQF syntax has been introduced in Operation Flashpoint: Resistance v1.85 and is the Arma series' main scripting language since. The main differences with SQS syntax are:

  • execVM is used (instead of exec for SQS)
  • Every command has to end with a semicolon (;)
  • the following commands disappeared:
    • goto/#label (Note, # is a command in itself in Arma 3)
    • exit - a partial SQF equivalent can be found in exitWith
  • Line returns do not impact code
  • SQF can return a variable, where SQS cannot

Conversion examples

Comment

; This is a comment

; This is a ; multiline ; comment 

comment "this is a comment";

"this is a comment";

// This is single-line comment

/*
	This is a
	multiline
	comment
*/

comment "this is a comment";

"this is a comment";

Condition wait

@CONDITION

@ not alive player

waitUntil { CONDITION };

waitUntil { not alive player };

Delay

~DELAY

~5

sleep DELAY;

sleep 5;

Conditional command

? CONDITION : COMMAND

? alive player : player setDammage 1

if (CONDITION) then { COMMAND };

if (alive player) then { player setDammage 1 };

Multi-conditional command

? CONDITION : goto "SKIP"
 COMMAND_2
 goto "END"
#SKIP
 COMMAND_1
#END

if (CONDITION) then {
	COMMAND_1
} else {
	COMMAND_2
};

Cycle

#loop
 COMMAND
 ~DELAY
? CONDITION : goto "LOOP"

while {CONDITION} do {
	COMMAND;
	sleep DELAY;
};

Cycle with step

_i = 0
#LOOP
 COMMAND
 _i = _i + 1;
? _i < COUNT : goto "LOOP"

for "_i" from 0 to COUNT -1 do {
	COMMAND;
};

Structured conditional command

? VARIABLE == VALUE_1: goto "SKIP_1"
? VARIABLE == VALUE_2: goto "SKIP_2"
 DEFAULT_COMMAND
 goto "END"
#SKIP_1
 COMMAND_1
 goto "END"
#SKIP_2
 COMMAND_2
#END

switch (VARIABLE) do {
	case VALUE_1:
		{ COMMAND_1 };
	case VALUE_2:
		{ COMMAND_2 };
	default
		{ DEFAULT_COMMAND };
};

Exiting

? CONDITION : COMMAND_2
? CONDITION : exit
 COMMAND_1

if (CONDITION) exitWith { COMMAND_2; };
COMMAND_1;
