lua.wetgenes.gamecake.zone.scene.add
scene:add(it)
scene:add(it,caste)
scene:add(it,caste,boot)
Add a new item of caste or it.caste to the list of things to update.
The optional boot table contains initialisation/reset values and will be remembered in item.boot. If boot.id is given then we will remember this item with a call to scene.set(id,it)
The actual act of initalising the item from the boot table is left to custom code which ideally should initalize it and then just call scene.add(it) as the auto shortcuts are unnecesary.
