Movement is not smooth (SOLVED)

Questions
1

I got a code which makes moving a crosshair. But her movement is not smooth. How do I solve?

local rot
function init(self)
   msg.post(".", "acquire_input_focus")
   go.set_position(vmath.vector3(0,-190,1))
   rot = go.get(".", "euler.z")			-- Get rotation
end

function update(self, dt)
   go.set(".", "euler.z", rot)			-- Set rotation
end

function on_input(self, action_id, action)
    if action_id == hash("esq") and (action.pressed or action.repeated) and (rot <= 180) then
   	   -- move left
	   rot = rot + 1
    elseif action_id == hash("dir") and  (action.pressed or action.repeated) and (rot >= 0) then
	   rot = rot - 1
    end
end

You’re only moving the crosshair when the button is pressed and when it’s repeated. You should do it continuously instead. Also, module-local variables (rot) are likely to break if you have multiple instances of the script.

function init(self)
  msg.post(".", "acquire_input_focus")
  go.set_position(vmath.vector3(0,-190,1))
  self.rotation = go.get(".", "euler.z")
  self.rotation_velocity = 0
end

function update(self, dt)
  local rotation = self.rotation + self.rotation_velocity * dt
  rotation = math.max(0, math.min(180, rotation))
  self.rotation = rotation
  go.set(".", "euler.z", rotation)
end

function on_input(self, action_id, action)
  if action_id == hash("esq") then
    self.rotation_velocity = action.value * 60.0 -- Adjust this factor to your liking
  elseif action_id == hash("dir") then
    self.rotation_velocity = -action.value * 60.0 -- Adjust this factor to your liking
  end
end

Thank you! Worked 100%, now I’m going to study these functions.
