Each node in the graph is a separate object and they are represented as a rectangular boxes with title and a set of properties. Each node has also connection ports that allow to connect it to another nodes and control the flow of the shader. </description> <tutorials> <link title="VisualShaders">$DOCS_URL/tutorials/shaders/visual_shaders.html</link> </tutorials> <methods> <method name="clear_default_input_values"> <return type="void" /> <description> Clears the default input ports value. </description> </method> <method name="get_default_input_values" qualifiers="const"> <return type="Array" /> <description> Returns an [Array] containing default values for all of the input ports of the node in the form [code][index0, value0, index1, value1, ...][/code]. </description> </method> <method name="get_input_port_default_value" qualifiers="const"> <return type="Variant" /> <param index="0" name="port" type="int" /> <description> Returns the default value of the input [param port]. </description> </method> <method name="remove_input_port_default_value"> <return type="void" /> <param index="0" name="port" type="int" /> <description> Removes the default value of the input [param port]. </description> </method> <method name="set_default_input_values"> <return type="void" /> <param index="0" name="values" type="Array" /> <description> Sets the default input ports values using an [Array] of the form [code][index0, value0, index1, value1, ...][/code].
