Cocos2d-x Lua Render Order: setLocalZOrder and Sibling Nodes

In
Control Cocos2d-x Lua sibling rendering order with setLocalZOrder, understand larger and equal Z-order values, child arrival order, and scene-graph branch limits.

Set a Node’s Local Z Order

Set a node’s local Z order with:

1
node:setLocalZOrder(0)

Among sibling nodes, a larger local Z-order value is normally drawn above a smaller one. This affects ordering under the same parent; it is not a global layer shared across unrelated branches of the scene graph.

When siblings have the same Z order, their arrival or child order may decide which is drawn later. Use a small, documented range of layer constants rather than scattered unexplained numbers.
