A Plug is an attribute of a node. The plug can be "readable" only or "readable and writable".

A Plug is implemented with a Lua table.

Documentation

nil adddependencies ( Plug ... )

Connect outputs plug to this plug

Arguments:

  • ... The list of plugs to connect to this plug

nil adddependency ( Plug output )

Connect an output plug to this plug

Arguments:

  • output The output to connect to this plug

nil connect ( Plug output , boolean safe )

Connect an output plug to this plug

Arguments:

  • output The output to connect to this plug
  • safe Is true, no error if the plug is already connected. In this case, replace the old connection by the new one. If false, raise an error if the plug is already connected.

nil delete ( )

Delete this plug.

nil disconnect ( Plug output )

Disconnect an output plug from this plug

Arguments:

  • output The output to connect to this plug

nil disconnectall ( )

Disconnect a plug from all its connections

nil disconnectcontrol ( )

Disconnect the plug from its input and delete the input if it is a control and it is no longer connected

nil get ( )

Returns the value of a plug. The plug must be readable.

If the plug was invalidated, its value is recomputed.

nil getbackdependencies ( )

Retrieve the list of plugs this plug has dependencies on, or nil if none

nil getdependencies ( )

Retrieve the list of plugs this plug is dependent on, or nil if none

types.bool state getflag ( number flag )

Get a specific plug flag.

Arguments:

  • flag the flag to retrieve

Return:

  • state The current state

number flags getflags ( )

Gets the plug flags.

A Plug has various flags that indicate parts of the Plug state. The addressable flags are:
  • Plug.Dynamic: the plug is create dynamically, not within the node constructor
  • Plug.NoSerial: the plug connection, dependencies and value are not written to file
  • Plug.KeepOnCopy: the plug connection and dependencies to out of copy/paste space are written (for instance, when copy/pasting a primitive, the connection to the material is kept)
  • Plug.RefReadOnly: the plug value and incoming connection/dependencies are kept untouched if the plug is read from a reference
Return:

  • flags

nil getinmotion ( int steps , float time , float start , float stop )

Return an array of values of this plug evaluated in time.

The array is always of size 'steps'. If this plug is connected to a curve driven by the document's time, this method will evaluate the value in the desired time steps. If not, it will return 'steps' times the current plug value.
Arguments:

  • steps Number of motion steps wanted
  • time Base time at which we want the motion values
  • start Delta time from the base time for the first value
  • stop Delta time from the base time for the last value

Plug result getinput ( )

Returns the input connection

Return:

  • result the connected input plug

nil getname ( )

Returns the name of the plug in its parent

nil getnode ( )

Returns the parent node of the plug

{Plug} result getoutputs ( )

Returns the list of output connections

Return:

  • result the connected output plugs or nil if no plug is connected

nil getpath ( )

Returns the path of the plug

nil getraw ( )

Returns the raw value of a plug, regardless of its invalidation state.

nil gettype ( )

Get the type associated to the plug

nil hasbackdependencies ( )

Tells if some plugs are dependent on this plug

nil hasdependencies ( )

Tells if the plug is dependent on other plugs

bool result hasoutputs ( )

Tells if the plug is connected in output to some other plugs

Return:

  • result True if the plug is connected in output

nil isanimatable ( )

Tells if the plug value can be animated

boolean result isconnected ( Plug output )

Test if a plug is connected to another

Arguments:

  • output The output to test connection

Return:

  • result

boolean dependent isdependent ( Plug plug )

Returns true if this plug is dependent on other

Arguments:

  • plug The plug to test dependency on

Return:

  • dependent True if this plug is dependent on plug

nil isrefoverriden ( )

Tells if the plug state is overriden from its reference state

boolean result isvalid ( )

Returns the validity status of the plug

Return:

  • result

nil removealldependencies ( )

Remove all input dependencies of this plug

nil removedependencies ( Plug ... )

Connect an output plug to this plug

Arguments:

  • ... The list of plugs to disconnect to this plug

nil removedependency ( Plug output )

Connect an output plug to this plug

Arguments:

  • output The output to connect to this plug

nil set ( Type value )

Set the value of a plug. The plug must be writable.

All the plugs dependent of this plug will be invalidated.
Arguments:

  • value The new value to put in the plug

nil setflags ( number flags )

Sets the plug flags

Arguments:

  • flags the flags to set.

nil setvalid ( )

Force the plug valid state, but the plug is not evaluated.

string result tostring ( )

Returns a human readble string of the plug's value

Return:

  • result the string value

nil touch ( )

Invalidate this plug

nil validate ( )

Force the plug validation by evaluating the plug.

nil flushinvalidation ( )

Flush the invalidation counter
