Reaching cocos objects

8 Ball Pool is a cocos2d game running a Cocotron Objective-C runtime on both iOS and Android, so on either build the ffi capability’s objc, cocos and memory globals reach the game’s own objects, and reflect reads their fields by name. Use these when you need something the pool namespace does not already hand you; for everything the namespace covers, prefer the namespace.

These globals are gated (ffi for memory/ffi/objc/cocos, reflect for reflect). memory/ffi work on every build; objc/cocos work on the cocos (Cocotron) builds — iOS and Android — and are nil on non-cocos games. Always guard.

Walking the scene

if cocos then
  local root = cocos.running_scene()
  if root then
    for _, child in ipairs(root:children()) do
      client.log(child:name(), child:position())
    end
  end
end

Messaging a node

-- hide a node by sending it setVisible: through objc
if objc and cocos then
  local node = cocos.running_scene():child("SomeOverlay")
  if node then
    objc.object(node:pointer()):msg("setVisible:", "v(b)", false)
  end
end

Reading a field by name

n:field(...) on a node returns a reflect handle you can read typed values from. Handles are frame-scoped: take and read in the same frame.

if cocos then
  local node = cocos.running_scene():child("GameLayer")
  if node then
    local n = node:field("someIntField"):i32()
    if n then client.log("field =", n) end
  end
end

Reads never crash on a bad address; they return nil. Selector and class strings come from your script, never from the game binary.
