showWhen()

Shows a question, text or container only while a checkbox is ticked, or while an option is chosen. Every dialog item has it.

Signature​

showWhen(checkBoxId: number): DialogComponent
showWhen(radioGroupId: number, optionId: number): DialogComponent

Parameters​

ParametersTypeDescription
checkBoxIdnumberShow while the CheckBox with this id is ticked
radioGroupIdnumberThe RadioGroup (or dropdown) to watch
optionIdnumberShow while the RadioButton with this id is chosen

Returns

The same item, so calls can chain

Example​

Dialog:add(CheckBox(1, "Collect daily rewards"))
Dialog:add(NumberInput(2, "Rewards to collect", 3):showWhen(1))

local mode = RadioGroup(3, 1)
mode:add(RadioButton(1, "Farm"))
mode:add(RadioButton(2, "Arena"))
Dialog:add(mode)
Dialog:add(TapPicker(4, "Tap the Arena button"):showWhen(3, 2))

Notes​

  • For the opposite, use hideWhen().
  • A hidden question never keeps OK grey, and keeps its last answer.
  • If the watched checkbox or group is hidden itself, the item hides too.
  • Watching an id that isn't a CheckBox or RadioGroup, or a RadioGroup without an optionId, stops the dialog with an error.
