def alpha
  @alpha
end

#anchor_point ⇒ Point

The anchor point of the node, as a set of percentage coordinates. The anchor point represents where the node will be attached to its parent, and is normalized as a percentage. [0, 0] means the bottom-left corner, and [1, 1] the top-right corner. You can also use values lower than 0 and higher than 1. The default anchor point value is [0.5, 0.5], which means the center of the parent.

Instance Method Details

#add(node, zpos = 0) ⇒ self

Adds a child node to the receiver with a local z-order.



768
 
# File 'doc/API_reference.rb', line 768

def add(node, zpos=0); end

#children ⇒ Array<Node> 



787
 
# File 'doc/API_reference.rb', line 787

def children; end

#clear(cleanup = true) ⇒ self

Removes all children nodes from the receiver.



774
 
# File 'doc/API_reference.rb', line 774

def clear(cleanup=true); end

#delete(node, cleanup = true) ⇒ self

Removes the given child node from the receiver.



780
 
# File 'doc/API_reference.rb', line 780

def delete(node, cleanup=true); end

#delete_from_parent(cleanup = true) ⇒ self

Removes the receiver node from its parent. Same as:

node.parent.delete(node, cleanup)

#parent ⇒ Node 



783
 
# File 'doc/API_reference.rb', line 783

#run_action(action) { ... } ⇒ self

Run the provided action on the receiver node.

Yields:

  • if passed a block, the block will be called for the action.



745
 
# File 'doc/API_reference.rb', line 745

def run_action(action); end

#schedule(delay, repeat = 0, interval = 0) {|Float| ... } ⇒ String

Schedules a given block for execution.

Yields:

  • (Float) —

    the given block will be yield with the delta value, in seconds.



809
 
# File 'doc/API_reference.rb', line 809

def schedule(delay, repeat=0, interval=0); end

#schedule_once(delay) {|Float| ... } ⇒ String

Schedules a given block for execution that runs only once, with a delay of 0 or larger.

Yields:

  • (Float) —

    the given block will be yield with the delta value, in seconds.



817
 
# File 'doc/API_reference.rb', line 817

def schedule_once(delay); end

#stop_action(action) ⇒ self

Stop the provided action



754
 
# File 'doc/API_reference.rb', line 754

def stop_action(action); end

#stop_all_actions ⇒ self

Stop all actions running on the node



749
 
# File 'doc/API_reference.rb', line 749

def stop_all_actions(); end

#unschedule(key) ⇒ self

Unschedules a task that’s currently running.



823
 
# File 'doc/API_reference.rb', line 823

def unschedule(key); end

#visible=(value) ⇒ Object

Set whether the node is visible.



711
 
# File 'doc/API_reference.rb', line 711

def visible=(value); end

#visible? ⇒ Boolean 



715
