Instantiating Classes

Note

ClassDB extensions registered by Go can be instantiated with the builtin new function.

Each object provided by the engine is available under the graphics.gd/classdb, they can be instantiated using the New function defined in their respective package.

The New function will return the convenient Instance type, which will include all of the methods available on that object (which will be exclusively using convienience types and do not include any optional arguments). Instance values can be converted to both Advanced types for low-level use and Expanded types (which include all optional arguments).

package main

import (
  "graphics.gd/startup"
  "graphics.gd/classdb/Node"
  "graphics.gd/variant/String"
)

func main() {
  startup.Rendering()

  var node Node.Instance = Node.New()
  node.SetName("Hello World")

  var advanced = Node.Advanced(node)
  advanced.SetName(String.New("Hello World"))

  var id Node.ID = node.ID() // all instances have an ID type and method.
  fmt.Println("Node ID:", id)
}
