Description

Description:

Sets given event handler of in-game UI. If EH function returns true, performed action is overridden. Event handlers available are:

• "PrevAction" - mouse scroll up
• "Action" - action key press
• "NextAction" - mouse scroll down

In order to remove a previously added event handler, set it again with an empty code string "".

⚠

This is a "set" command, which means event handlers are not stackable and will replace previously set event handlers of the same type.

Since Arma 3 v1.50 the event handler receives an array of the selected/activated action's arguments in _this variable:

params ["_target", "_caller", "_index", "_engineName", "_text", "_priority", "_showWindow", "_hideOnUse", "_shortcut", "_visibleMenu", "_eventName"];

• _target: Object - target object to which action is attached
• _caller: Object - caller object, basically player
• _index: Number - index of the action in action menu (0 - top most)
• _engineName: String - engine based action name ("User" for user added actions)
• _text: String - localized action plain text as seen by the caller
• _priority: Number - action priority value
• _showWindow: Boolean - action showWindow value
• _hideOnUse: Boolean - action hideOnUse value
• _shortcut: String - action shortcut name or ""
• _visibleMenu: Boolean - action menu visibility - on first scroll or action press the menu is still invisible, the menu is shown but no action is performed
• _eventName: String - event name

In case of the "Action" event, (_showWindow || _visibleMenu) also denotes if the action is performed or not. For example, if the action menu is closed or fading off, pressing Spacebar will bring it up and trigger an "Action" event; in that case, _visibleMenu is false. But if the action menu is open, and Spacebar is pressed to perform the selected action, then _visibleMenu will be true. If _showWindow is true, then it means the action was performed, regardless of _visibleMenu.
