YaEventAPI

YaEventAPI enables users send events to an event handler.

The following code shows how to register an event handler, issue an event and remove an event handler.

local entityId = script:SelfEntity().EntityId  -- get the id of the entity the script attached to
local option = EventOption.New():SetScope("NewGame"):SetBoundEntityId(entityId)  -- create an option with scope "NewGame" and associate the entity with this option

local h1 = YaEventAPI.OnEventFromLocal("hello", option, function(payload)
    local content = payload:GetContent()       -- get content from the received payload
    local text = table.concat(content, " ")
    print("[hello.handler.1]", text)
end)
local h2 = YaEventAPI.OnEventFromLocal("hello", option, function(payload)
    local content = payload:GetContent()       -- get content from the received payload
    local text = table.concat(content, " ")
    print("[hello.handler.2]", text)
end)

local helloWorldPayload = EventPayload.New({"Hello", "World"})    -- create a payload
YaEventAPI.FireToLocal("hello", option, helloWorldPayload)        -- send "hello" event, two handlers will be invoked
h1:Disconnect()                                                   -- removes the first registered handler
local helloYahahaPayload = EventPayload.New({"Hello", "Yahaha"})  -- create another payload
YaEventAPI.FireToLocal("hello", option, helloYahahaPayload)       -- send "hello" event, only the second handler will be invoked
h2:Disconnect()                                                   -- removes the second registered handler

The output may be:

[hello.handler.2]    Hello World
[hello.handler.1]    Hello World
[hello.handler.2]    Hello Yahaha
