• #on_attach ⇒ Object

  Tree-lifecycle hooks.

• #on_detach ⇒ Object
• #sweep_freed ⇒ Object

  Container components (e.g. SceneStack) that hold nodes off the normal child list override this to forward the deferred-free sweep into them.

Instance Method Details

#context ⇒ Object

# File 'lib/rgame/engine/component.rb', line 10

def context
  @context ||= node.context
end

#control(actions) ⇒ Object

# File 'lib/rgame/engine/component.rb', line 21

def control(actions); end

#draw(renderer, view) ⇒ Object

# File 'lib/rgame/engine/component.rb', line 23

def draw(renderer, view); end

#on_attach ⇒ Object

Tree-lifecycle hooks. on_attach fires once the node is in the live tree, so node.root / node.scene and sibling systems are reachable — pull and register shared systems here, not in initialize (where the node has no anchors yet). on_detach mirrors it: release those registrations.

# File 'lib/rgame/engine/component.rb', line 18

def on_attach; end

#on_detach ⇒ Object

# File 'lib/rgame/engine/component.rb', line 19

def on_detach; end

#sweep_freed ⇒ Object

Container components (e.g. SceneStack) that hold nodes off the normal child list override this to forward the deferred-free sweep into them.

# File 'lib/rgame/engine/component.rb', line 27

def sweep_freed; end

#update(dt) ⇒ Object

# File 'lib/rgame/engine/component.rb', line 22
