It seems like you have opened this file by double-clicking on it. In order to test your build in a browser you need to load this file from a web server. You can either upload this file and the rest of the files from a Defold HTML5 bundle to a web hosting service OR host them using a local web server on your home network.
The example shows how to use Defold built-in timer and trigger it asynchronously and uses two indicators:
The timer triggers update of the counter every 1s. Click anywhere to trigger the callback of the timer asynchronously.
function init(self) self.count = 0 -- <1> local interval = 1 -- <2> local repeating = true -- <3> self.timer = timer.delay(interval, repeating, function() -- <4> self.count = self.count + 1 -- <5> local node = gui.get_node("counter") -- <6> gui.set_text(node, self.count) -- <7> end) msg.post(".", "acquire_input_focus") -- <8> end function on_input(self, action_id, action) if action_id == hash("touch") and action.pressed then -- <9> timer.trigger(self.timer) -- <10> end end --[[ 1. Start the count with value 0. 2. We will use interval of 1 [s]. 3. We will be repeating the timer endlessly. 4. Start the timer with interval (1s) and repeating (true) and pass a callback function. Store the handle to the timer in self.timer. 5. The function will be called every 1s, so increase the count by 1 each time. 6. Get the counter text node. 7. Update the counter text node with an increased count. 8. Tell the engine that this game object wants to receive input. 9. If the user clicks. 10. Trigger the timer's callback function asynchronously using the saved self.timer handle. --]]
