Defined in ../src/litegraph.js:1419

add a new output slot to use in this node

Parameters:

  • name String
  • type String

    string defining the output type ("vec3","number",...)

  • extra_info Object

    this can be used to have special properties of an output (special color, position, etc)

addOutputs

(
  • array
)

Defined in ../src/litegraph.js:1440

add a new output slot to use in this node

Parameters:

  • array Array

    of triplets like [[name,type,extra_info],[...]]
