Vague errors in the script (SOLVED)

Questions
1

I’m following the tutorial “War battles” and encountered a problem - got errors in the script:
ERROR:SCRIPT: /main/player.script:51: attempt to call field ‘lenght’ (a nil value)
stack traceback:
/main/player.script:51: in function </main/player.script:38>
ERROR:SCRIPT: /main/player.script:22: attempt to index global ‘factoy’ (a nil value)
stack traceback:
/main/player.script:22: in function </main/player.script:14>

The script:

function init(self)
	msg.post(".", "acquire_input_focus")
	self.moving = false
	self.firing = false	
	self.input = vmath.vector3()
	self.dir = vmath.vector3(0, 1, 0)
	self.speed = 50
end

function final(self)
	msg.post(".", "release_input_focus")
end

function update(self, dt)
	if self.moving then
		local pos = go.get_position()
		pos = pos + self.dir * self.speed * dt 
		go.set_position(pos)
	end

	if self.firing then
		factoy.create("#rocketfactory")
	end
	
	self.input.x = 0
	self.input.y = 0
	self.moving = false
	self.firing = false
end

function on_input(self, action_id, action)
	if action_id == hash("up") then
		self.input.y = 1
	elseif action_id == hash("down") then
		self.input.y = -1
	elseif action_id == hash("left") then
		self.input.x = -1
	elseif action_id == hash("right") then
		self.input.x = 1
	elseif action_id == hash("fire") and action.pressed then
		self.firing = true
	end

	if vmath.lenght(self.input) > 0 then
		self.moving = true
		self.dir = vmath.normalize(self.input)
	end
end

I suppose that a line: “self.input = vmath.vector3()” in the “function init” initializes the vector3() to 0.

This is a screenshot of the main.collection

Thanks in advance

There is a typo

It should be
factory.create("#rocketfactory")

and

should be
if vmath.length(self.input) > 0 then

Thank you. It was difficult to see a typo because a word was colored blue and I supposed that all is ok. I’m used to Visual Studio, where all typos and mistakes are immediately shown.

You should still get auto-complete in our editor for methods that are part of our API. E.g typing “factory.” should present the methods available in the factory namespace.

We could perhaps highlight the errors more clearly also.
