Button

Simple input handler for gui nodes that should act as buttons. Register nodes and pass any call to on_input() to this module and it will automatically do picking and invoke a registered callback.

Usage

The Button module can be used via button.lua:

local button = require "in.button"

function init(self)
	msg.post(".", "acquire_input_focus")

	button.register(gui.get_node("blue"), function()
		print("blue")
	end)

	button.register("green", function()
		print("green")
		local scale = math.random(1, 5)
		gui.set_scale(gui.get_node("blue"), vmath.vector3(scale, scale, 1))
	end)
end

function final(self)
	button.unregister("blue")
	button.unregister("green")
end

function on_input(self, action_id, action)
	button.on_input(action_id, action)
end
