this is the error:

this is the script:
function init(self)
msg.post(".", “acquire_input_focus”)
self.moving = false
self.firing = false
self.input = vmath.vector3()
self.dir = vmath.vector(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
		local angle = math.atan2(self.dir.y, self.dir.x)
		local rot = vmath.quat_rotation_z(angle)
		local props = { dir = self.dir }
		factory.create("#rocketfactory", nil, rot, props)
	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

@OURABIG Did you read the error description?
It says it’s on line 45, and on line 45 you have:

if vmath.lenght(self.input) > 0 then

You’ve made a typo, and you’ve misspelled “vmath.length” wrong.
And since there is no symbol with that name, you get nil instead.
