ToolButtonPlugin for Godot 4.0 - v1.4

Editor buttons with ~~one line of code: @tool~~ zero lines of code.

Simply install, and select any node:

Public methods will be listed at the bottom of editor panel.
Signals with 0 arguments will also be shown.

For more advanced features, read below.

Getting Started

Enable plugin.
Add @tool to top of your script.
Add a _get_tool_buttons() -> Array method.
The array items can be:
- Names of methods "my_method"
- Method itself my_method
- Bound method method.bind(true, "ok" 1.0)
- Anonymous methods func(): print("Hey!")
- Anonymous methods with name func press_me(): print("You pressed me!")
- Names of signals "my_signal"
- Signal itself my_signal
- Array with signal and arguments ["my_signal", [true, "ok"]]
- Dictionarys with fine tuned control: {call=method.bind(true), text="My Method", tint=Color.RED}
- Arrays with any of the above ["my_method", method2.bind(1.0), "a_signal", {text="X", call=reset}]

Advanced Example

To specify buttons that show above the inspector, add a _get_tool_buttons func.

With Strings:

@tool
extends Node

func _get_tool_buttons():
	return [boost_score, remove_player]

func boost_score():
	Player.score += 100

func remove_player():
	Player.queue_free()

and/or Callables

# WARNING, some stuff won't work: If you get *"Cannot access member without instance"*: https://github.com/godotengine/godot/issues/56780
@tool
extends Node

func _get_tool_buttons():
	return [
		func add_score(): score += 10,
		func reset_health(): health = 0
	]

and/or Dictionarys

@tool
extends Node

signal reset()

func _get_tool_buttons(): return [
	"boost_score",
	{call="boost_score", args=[100], tint=Color.DEEP_SKY_BLUE},
	{call="emit_signal", args=["reset"], text="Reset", tint=Color.TOMATO},
	{
		call=func(): print("My Health: ", health),
		text="Print Health",
		tint=func(): return Color(health * .1, 0.0, 0.0)
		lock=func(): return health == 100
	}
]

func boost_score(x=10):
	Player.score += x

call is mandatory. Other's are optional.

Resource Example

For _get_tool_buttons to work on a Resource it needs to be static.

@tool
extends Resource
class_name MyResource

# STATIC
static func _get_tool_buttons():
	return ["my_button"]

# LOCAL
export(String) var my_name:String = ""

func my_button():
	print(my_name)

Signals

signal my_signal()
signal my_arg_signal(x, y)

func _get_tool_buttons():
	return [
		my_signal,
		[my_arg_signal, [true, "okay"]]
	]

Multi button support

You can have multiple buttons on the same line.
They can all be called at once (default), or seperate, based on a toggle.

func _get_tool_buttons():
	return [
		[msg, msg.bind("yes"), msg.bind("no")],
	]

func msg(msg := "Default Message"):
	print("Got: ", msg)

func doit():
	pass
