Description

Description:
Composes a string containing other variables or other variable types. Converts any variable type to a string. If you want to convert a string back to a number, use parseNumber.
⚠
The output of this command is limited to ~8Kb. joinString on the other hand doesn't have such limit and is a bit faster.
ⓘ
Since Arma 3 logo black.png2.20 the maximum length of the string is 8388608 characters. Additionally, two consecutive percent symbols will be formatted to a single percent symbol in the final string (%% -> %)
Groups:
Strings

Syntax

Syntax:
format [formatString, var1, var2, ...]
Parameters:
formatString: String - a string containing text and/or references to the variables listed below in the array. The references appear in the form of %1, %2 etc.
varN: Anything - variable referenced by %N
Return Value:
String - the full string (up to 8kb, see above) is returned.

Examples

Example 1:
format ["Player:%1, player's side:%2", player, side player]; // returns "Player:WEST 1-1-A:1 (Username), player's side:WEST"
Example 2:
player addEventHandler ["HandleDamage", { hint format ["You just sustained %1%2 damage!", ceil ((_this select 2) * 100), "%"]; }]; // Shows "You just sustained 20% damage!"
Example 3:
// Since Arma 3 v2.18 two consecutive percent symbols will be formatted to a single percent symbol in the final string (%% -> %) player addEventHandler ["HandleDamage", { hint format ["You just sustained %1%% damage!", ceil ((_this select 2) * 100)]; }]; // Shows "You just sustained 20% damage!"

The maximum number of characters returned by the format command seems to depend on the total byte count. For plain ASCII strings the limit is 2048 characters.

In addition to the note above, formatTexted strings are Structured Text, hence cannot be used like formatted strings (with most scripting commands). A workaround to get strings of type String with more than 8191 characters is:
str formatText ["%1", _string]
