Custom scripting gives experienced developers even more power by allowing you to run your own javascript.

###By Tiers###

Free and Pro-tier developers only have access to in-play scripting. Enterprise customers can run javascript anywhere in their game, including sets, community pages, landing pages, etc.

Getting started with JavaScript

The simplest way to try custom scripting is through the custom javascript action in the effect builder.

To use it, use the custom javascript action. All javascript is executed in the context of that action. Custom javascript action can be executed either client side or server side. Server side execution effects the logic of the game while client-side execution effects the rendering and visuals on the client. Even if your game doesn't have a server the logic of the game is still server-side with a local server.

Examples of custom javascript commands on the server:

console.log(thisCard)
thisCard.variable = {
  "foo": "bar"
}
console.log(parseVariable('$variable'))
console.log(dotSyntax('$variable.variable2'))

Local Variables

thisCard

effectIndex

effectIndex effectIndex

Global Variables

thisMatch

Helper Functions

clientUpdateCard(thisMatch, ciid)

ciid parameter

A number that is a ciid.

otherPlayer(playerNumber)

In games with 2 players, get the playerNumber of the other player. Returns either string "player1" or "player2"

getIndexFromEffectName(effectName, context)

Returns index as number.

effectName parameter

A string that is the name of the effect. Typically saved by assign variable. Should be in either _effectTriggers or _effectNames.

context parameter

Optional. Default thisCard.

runEffectFromAnotherAction(effect, callback)

effect parameter

A string that evaluates to an effectIndex or an array of effectIndexes.

callback parameter

Optional.

runEffect(thisMatch, options, callback)

thisMatch parameter

Specify the match. Should always be "thisMatch".

options parameter

callback parameter

Optional.

getIndexFromEffectName(effectName)

effectAfterAction()

Proceed to the effect completion.

assignTargetVariable(target, key)

target parameter This assigns the target to the line like the assign variable action. The target may be any number, string, object, function or array of ciids.

key parameter Optional. Create an additional property on thisCard in the form of effect-${effects.effectName}Key.

safeEvalInput(string)

Checks to see if there's math that can be done. If there is, do the math and return a number. Otherwise return the string.

dotSyntax(string)

Like parseVariable but works with dot syntax.

stringVariableReplacement(string)

With a string, replace any variables within. Uses dotSyntax. Example:

stringVariableReplacement("This card is called $title. It has an attack power of $atk and a health of $health.")

effectSelectCard()

Returns all possible choices based on the target
