showInventory(player); is passing a type as parameter. That’s illegal, you need to pass an object. For example, something like: I’m guessing you have something like this: which is awful. First, don’t name the object the same as your type. Second, in order for the object to be visible inside the function, you’ll need to pass it … Read more
Maybe you just need to commit. I ran into this when I did: Oops! Never committed! All I had to do was: Success!
There could be many reasons, but the most common are: The port is not open on the destination machine. The port is open on the destination machine, but its backlog of pending connections is full. A firewall between the client and server is blocking access (also check local firewalls). After checking for firewalls and that … Read more
There is an experimental webkit property called text-stroke in CSS3, I’ve been trying to get this to work for some time but have been unsuccessful so far. What I have done instead is used the already supported text-shadow property (supported in Chrome, Firefox, Opera, and IE 9 I believe). Use four shadows to simulate a stroked text: Run code … Read more
They are being divided in integer arithmetics. So dividing integer a by integer b you get how many times b fits into a. Also a % b will give you a remainder of a division. So (a / b ) * b + a % b = a
If you’re only targeting modern browsers: Use element.classList.add to add a class: And element.classList.remove to remove a class: If you need to support Internet Explorer 9 or lower: Add a space plus the name of your new class to the className property of the element. First, put an id on the element so you can easily get a reference. Then Note the space … Read more
The wording of the error message corresponds to what you get from Google Chrome when you run JSON.parse(‘<…’). I know you said the server is setting Content-Type:application/json, but I am led to believe the response body is actually HTML. Feed.js:94 undefined “parsererror” “SyntaxError: Unexpected token < in JSON at position 0” with the line console.error(this.props.url, status, err.toString()) underlined. The err was actually thrown … Read more

You can get a specific character from a string simply by indexing it. For example, the fifth character of str is str[4] (off by one since the first character is str[0]). Keep in mind you’ll run into problems if the string is shorter than your index thinks it is. c_str(), as you have in your comments, gives you a char* representation (the … Read more
As the others have said, you can use var at global scope (outside of all functions and modules) to declare a global variable: (Note that that’s only true at global scope. If that code were in a module — <script type=”module”>…</script> — it wouldn’t be at global scope, so that wouldn’t create a global.) Alternatively: In modern environments, you can assign to … Read more
