# 获取全局属性
print(nuke.root())
nuke.zoom()
# 返回所有选中节点实例的列表
print(nuke.selectedNodes())
# 返回名字为Write1的节点实例
print(nuke.toNode("Write1"))
# 返回当前节点实例
print(nuke.thisNode())
# 创建节点实例两种方案，NodeClass是节点类型，可以通过在具体节点上按i键或者通过Class()方法查看节点类型
print(nuke.createNode("NodeClass"))
print(nuke.nodes.NodeClass())
# 返回某一类型所有节点实例列表
print(nuke.allNodes("NodeClass"))
# 返回所有插件路径
print(nuke.pluginPath())
- Callback函数
nuke.addAfterRender()
nuke.addOnUserCreate()
nuke.addKnobChange()
- 节点实例对象属性与方法
nuke模块中有很多函数可以返回节点实例对象，下面是一些常用的函数。
nuke.selectedNodes()
nuke.toNode()
nuke.thisNode()
nuke.createNode()
nuke.nodes.Read()
有了节点实例对象就可以获取关于节点数据类型属性以及方法。
[‘Class’, ‘__class__’, ‘__delattr__’, ‘__doc__’, ‘__format__’, ‘__getattribute__’, ‘__getitem__’, ‘__hash__’, ‘__init__’, ‘__len__’, ‘__new__’, ‘__reduce__’, ‘__reduce_ex__’, ‘__repr__’, ‘__setattr__’, ‘__sizeof__’, ‘__str__’, ‘__subclasshook__’, ‘addKnob’, ‘allKnobs’, ‘autoplace’, ‘bbox’, ‘canSetInput’, ‘channels’, ‘clones’, ‘connectInput’, ‘deepSample’, ‘deepSampleCount’, ‘dependencies’, ‘dependent’, ‘error’, ‘fileDependencies’, ‘firstFrame’, ‘forceUpdateLocalization’, ‘forceValidate’, ‘format’, ‘frameRange’, ‘fullName’, ‘getNumKnobs’, ‘hasError’, ‘height’, ‘help’, ‘hideControlPanel’, ‘input’, ‘inputs’, ‘isLocalizationOutdated’, ‘isLocalized’, ‘isSelected’, ‘knob’, ‘knobs’, ‘lastFrame’, ‘linkableKnobs’, ‘localizationProgress’, ‘maxInputs’, ‘maxOutputs’, ‘maximumInputs’, ‘maximumOutputs’, ‘metadata’, ‘minInputs’, ‘minimumInputs’, ‘name’, ‘numKnobs’, ‘opHashes’, ‘optionalInput’, ‘performanceInfo’, ‘pixelAspect’, ‘proxy’, ‘readKnobs’, ‘redraw’, ‘removeKnob’, ‘resetKnobsToDefault’, ‘rootNode’, ‘running’, ‘sample’, ‘screenHeight’, ‘screenWidth’, ‘selectOnly’, ‘setInput’, ‘setName’, ‘setSelected’, ‘setTab’, ‘setXYpos’, ‘setXpos’, ‘setYpos’, ‘showControlPanel’, ‘showInfo’, ‘shown’, ‘treeHasError’, ‘upstreamFrameRange’, ‘width’, ‘writeKnobs’, ‘xpos’, ‘ypos’]
# 返回节点类型
node.Class()
# 节点在节点网络中的位置相关方法
setXYpos, setXpos, setYpos, xpos, ypos
# 添加自定义参数
addKnob
- 参数实例对象属性与方法
获取节点参数实例对象有下面两种常用的方法。
node["<parm_name>"]
node.knob("<parm_name>")
nuke.thisKnob()
有了节点参数实例对象就可以获取关于参数数据类型属性以及方法。
[‘Class’, ‘__class__’, ‘__delattr__’, ‘__doc__’, ‘__format__’, ‘__getattribute__’, ‘__hash__’, ‘__init__’, ‘__new__’, ‘__reduce__’, ‘__reduce_ex__’, ‘__repr__’, ‘__setattr__’, ‘__sizeof__’, ‘__str__’, ‘__subclasshook__’, ‘clearAnimated’, ‘clearFlag’, ‘critical’, ‘debug’, ‘enabled’, ‘error’, ‘evaluate’, ‘fromScript’, ‘fromUserText’, ‘fullyQualifiedName’, ‘getDerivative’, ‘getEvaluatedValue’, ‘getFlag’, ‘getIntegral’, ‘getKeyIndex’, ‘getKeyList’, ‘getKeyTime’, ‘getNthDerivative’, ‘getNumKeys’, ‘getText’, ‘getValue’, ‘getValueAt’, ‘hasExpression’, ‘isAnimated’, ‘isKey’, ‘isKeyAt’, ‘label’, ‘name’, ‘node’, ‘removeKey’, ‘removeKeyAt’, ‘setAnimated’, ‘setEnabled’, ‘setExpression’, ‘setFlag’, ‘setLabel’, ‘setName’, ‘setText’, ‘setTooltip’, ‘setValue’, ‘setValueAt’, ‘setVisible’, ‘splitView’, ‘toScript’, ‘tooltip’, ‘unsplitView’, ‘value’, ‘visible’, ‘warning’]
# 返回参数类型
parm.Class()
# 读取写入操作相关方法
getValue, getValueAt, setValue, setValueAt, value
