Lifecycle - UgCore

ug-core moves through seven states, always forward: A state can be skipped: a failed boot goes from Booting straight to Stopping. A skipped state is never reached.

Wait for Ready

UgCore.Lifecycle.On('Ready', function()
    -- Runs when ug-core is ready, or right away if it already is.
end)

CreateThread(function()
    if UgCore.Lifecycle.Await('Ready', 30000) then
        -- ready
    end
end)

On is sticky: a handler for a state already reached runs immediately. It never runs for a skipped state. Await returns false on timeout or when the state is skipped.

Check the state

UgCore.Lifecycle.GetState()             -- 'Ready'
UgCore.Lifecycle.IsReady()              -- true
UgCore.Lifecycle.HasReached('Starting') -- true

Lifecycle events

Event	Arguments
`ug-core:Lifecycle:Changed`	`newState, oldState`
`ug-core:Lifecycle:Ready`
`ug-core:Lifecycle:Stopping`

In your resource, UgCore.Lifecycle mirrors ug-core’s state from these events. When ug-core restarts, your handlers keep working.
