Hi,
I’m slowly getting the hang of Lua and its idiosyncrasies, but there is this piece of code I wan’t some more clarification:
[lua]local function onCollision(self, event )
if ( event.phase == “began” ) then
if event.other.properties then
local item = event.other
local onTransitionEnd = function(event)
event:removeSelf()
insertClone()
end[/lua]
ok, this onCollision() method will be called whenever a collision event happens. Then if event.phase is “began”, a onTransitionEnd closure will be create and… this closure will be called exactly when?
[lua]-- Fade out the item
transition.to(item, {time = 200, alpha = 0, onComplete=onTransitionEnd})[/lua]
for what I know about box2d, bodies cannot be removed from the application in between collision phases (i.e. “began” and “ended”), so I guess that the transition will be completed after the box2d collision event is complete. But how exactly? This time item in transition to is updated after the collision is complete?
