Description
- Description:
- Creates cycle, using C like style. See example.
- Groups:
- Uncategorised
Syntax
Examples
- Example 1:
for [{_x=1},{_x<=10},{_x=_x+1}] do {debugLog _x;}- Example 2:
_a = 0; for [{},{_a <= 10},{_a = _a + 1}] do {debugLog _a;};- Example 3:
for [{_a = 0; _b = 1},{_a <= 10},{_a = _a + 1; _b = _b + _b}] do {}; //_a = 11; _b = 2048;

- In ArmA3 ver 1.16 Please note the difference between for forspec and for do, for forspec detects Boolean in each scope while for do doesn’t. e.g.
command Structure Summary for forspec a = 0; b = true; for [{_i = 0},{_i < 10 && b},{_i = _i + 1}] do { a = a + 1; if (a >= 7) then {b = false} }
loop can be exited via Boolean control, possible workaround can be like BIS_fnc_areEqual for do a = 0; for "_i" from 0 to 10 do { a = a + 1; if (a >= 7) exitwith {} };
have to be exited via exitWith
- Never try to tell a decimal number via binary number in a loop; otherwise the loop will be infinite:
for [{_a = 0},{_a != 1},{_a = _a + 0.1}] do {}; //an infinite loop; _a will never be 1 so the scope will always be true.Any binary number behind the decimal point is always the sum of 1/2, 1/4, 1/8, 1/16 etc. so decimal number with odd denominator like 1/3 or 1/10 cannot be exactly equal to each other.- Avoid too large factorial multiply which may loose the leading indicator in result. And 12 is the biggest accessable factor in this example.
for [{_a = 2; _b = 1;},{_a < 100},{_a = _a + 1}] do {_b = _b * _a}; // _b = 1.#INF
