Events appear as properties on several objects. The goal is to register a function that will be fired whenever that event happens. For example
playerA.damagedEvent:Connect(OnPlayerDamaged) chooses the function
OnPlayerDamaged to be fired whenever
playerA takes damage.

| || ||Registers the given function which will be called every time the event is fired.

Core uses events for a variety of built-in state changes that can happen in a game. Events appear as properties on several objects. By connecting a function to the desired event, scripts can listen and act on them. In this example, both
player.damagedEvent are connected to. The
OnPlayerDamaged() function will be called each time a player takes damage. Any number of extra parameters can be added when connecting and those values will be passed back to the listening function.
function OnPlayerDamaged(player, dmg, joinTime) local elapsedTime = time() - joinTime print("Player " .. player.name .. " took " .. dmg.amount .. " damage after joining the game for " .. elapsedTime .. " seconds.") end function OnPlayerJoined(player) -- Passing extra float parameter player.damagedEvent:Connect(OnPlayerDamaged, time()) end Game.playerJoinedEvent:Connect(OnPlayerJoined)
