JASS

JASS is an event driven scripting language used in Blizzard Entertainment's Warcraft III game. Map creators can use it in the World Editor to create triggers and AI scripts.

Features

The language provides an extensive API that gives programmers control over nearly every aspect of the game world. It can, for example, give orders to units, change the weather and time of day, play sounds and display text to the player, and manipulate the terrain. It has a syntax similar to Delphi, although, unlike that language, it is case sensitive.

Sample code

The following function creates a string containing the message "Hello, world!" and displays it to all players:

function Trig_JASS_test_Actions takes nothing returns nothing
 local string a ="Hello, world!"
 call DisplayTextToForce( GetPlayersAll(), a )
endfunction
