Type Event Revision Release 2020.3619 Keywords lateUpdate, runtime See also Basic Interactivity and Event Detection (guide)
"lateUpdate" events occur at the
config.lua. They are only dispatched to the global Runtime object.
This is dispatched after the
"enterFrame" event, and right before the engine starts the rendering process. For this reason, it is useful to make any last update according to its state. Also, it is intended to be a safe call for all those who are listening to this event, otherwise, it loses its purpose.
local shouldUpdate = false local rect = display.newRect(100, 100, 30, 30) local x, y -- Change the state local touchListener = function( event ) x, y = event.x, event.y shouldUpdate = true print("I need to update my position.") -- This could be call more than once each frame. return true end rect:addEventListener("touch", touchListener) -- Interpretation of the new state local myListener = function( event ) if not shouldUpdate then return false end shouldUpdate = false rect.x, rect.y = x, y print("Position updated!") -- This is going to be called just once, before the game renders. end Runtime:addEventListener( "lateUpdate", myListener )
