Private _indexPrivate _listNumber of tags in set.
Private _hasPrivate _processFire an event, all additional arguments are passed on to the event listener.
Name of event to fire.
Optional arg1: anyFirst argument that is passed to the event handler.
Optional arg2: anySecond argument that is passed to the event handler.
Optional arg3: anyThird argument that is passed to the event handler.
Optional arg4: anyFourth argument that is passed to the event handler.
Optional arg5: anyFifth argument that is passed to the event handler.
Optional arg6: anySixth argument that is passed to the event handler.
Optional arg7: anySeventh argument that is passed to the event handler.

Check if tags satisfy filters. Filters can be provided by simple name of tag, as well as by array of tags. When an array is provided it will check if tags contain each tag within the array. If any of comma separated argument is satisfied, then it will return true. Any number of combinations are valid, and order is irrelevant.
Rest ...args: anyTrue if filters are satisfied.
tags.has('player'); // player
tags.has('mob', 'player'); // player OR mob
tags.has(['level-1', 'mob']); // monster AND level-1
tags.has(['ui', 'settings'], ['ui', 'levels']); // (ui AND settings) OR (ui AND levels)
Test if there are any handlers bound to an event name.
The name of the event to test.
True if the object has handlers bound to the specified event name.
obj.on('test', function () { }); // bind an event to 'test'
obj.hasEvent('test'); // returns true
obj.hasEvent('hello'); // returns false
Detach an event handler from an event. If callback is not provided then all callbacks are unbound from the event, if scope is not provided then all events with the callback will be unbound.
Optional name: stringName of the event to unbind.
Optional callback: HandleEventCallbackFunction to be unbound.
Optional scope: objectScope that was used as the this when the event is fired.
Self for chaining.
const handler = function () {
};
obj.on('test', handler);
obj.off(); // Removes all events
obj.off('test'); // Removes all events called 'test'
obj.off('test', handler); // Removes all handler functions, called 'test'
obj.off('test', handler, this); // Removes all handler functions, called 'test' with scope this
Attach an event handler to an event.
Name of the event to bind the callback to.
Function that is called when event is fired. Note the callback is limited to 8 arguments.
Optional scope: object = ...Object to use as 'this' when the event is fired, defaults to current this.
Can be used for removing event in the future.
obj.on('test', function (a, b) {
console.log(a + b);
});
obj.fire('test', 1, 2); // prints 3 to the console
const evt = obj.on('test', function (a, b) {
console.log(a + b);
});
// some time later
evt.off();
Attach an event handler to an event. This handler will be removed after being fired once.
Name of the event to bind the callback to.
Function that is called when event is fired. Note the callback is limited to 8 arguments.
Optional scope: object = ...Object to use as 'this' when the event is fired, defaults to current this.
obj.once('test', function (a, b) {
console.log(a + b);
});
obj.fire('test', 1, 2); // prints 3 to the console
obj.fire('test', 1, 2); // not going to get handled
Static EVENT_Fired for each individual tag that is added.
tags.on('add', (tag, parent) => {
console.log(`${tag} added to ${parent.name}`);
});
Static EVENT_Fired when tags have been added or removed. It will fire once on bulk changes, while add
and remove will fire on each tag operation.
tags.on('change', (parent) => {
console.log(`Tags changed on ${parent.name}`);
});
Static EVENT_Fired for each individual tag that is removed.
tags.on('remove', (tag, parent) => {
console.log(`${tag} removed from ${parent.name}`);
});
Set of tag names. Tags are automatically available on Entity and Asset as
tagsfield.
