void cocos2d::utils::captureScreen	(	const std::function< void(bool, const std::string &)> &	afterCaptured,
		const std::string &	filename
	)

Capture the entire screen To ensure the snapshot is applied after everything is updated and rendered in the current frame, we need to wrap the operation with a custom command which is then inserted into the tail of the render queue.

Parameters

afterCaptured,specify	the callback function which will be invoked after the snapshot is done.
filename,specify	a filename where the snapshot is stored. This parameter can be either an absolute path or a simple base filename ("hello.png" etc.), don't use a relative path containing directory names.("mydir/hello.png" etc.)

Since: v3.2

var captureScreen	(	var	afterCaptured,
		var	filename
	)

Parameters

afterCaptured,specify	the callback function which will be invoked after the snapshot is done.
filename,specify	a filename where the snapshot is stored. This parameter can be either an absolute path or a simple base filename ("hello.png" etc.), don't use a relative path containing directory names.("mydir/hello.png" etc.)

local captureScreen	(	local	afterCaptured,
		local	filename
	)

Capture the entire screen To ensure the snapshot is applied after everything is updated and rendered in the current frame, we need to wrap the operation with a custom command which is then inserted into the tail of the render queue.

Parameters

afterCaptured,specify	the callback function which will be invoked after the snapshot is done.
filename,specify	a filename where the snapshot is stored. This parameter can be either an absolute path or a simple base filename ("hello.png" etc.), don't use a relative path containing directory names.("mydir/hello.png" etc.)

Parameters

node	The node to find
name	The name to search for, it supports c++ 11 expression

Returns: Array of Nodes that matches the name

Since: v3.2

local findChildren	(	local	node,
		local	name
	)

Find children by name, it will return all child that has the same name.
