Game has also few custom levels that were used for development and can now be used to test different scripts.Ībout game interface languages: Game interface language can be set to English, German or Slovak but comments in script examples are always written in English.
There are 18 levels that require you to write code for your robots. Harder levels require robots to observe the environment for objects and other robots. This game was first intended to be used in schools and collages where students show interest in robot programming but don't have access to real robots or don't have sufficient amount of them.
Tutorial 0 should also teach you how to use Pyrois scripting language. Game features 11 tutorial levels that can help you understand how robots work. You can find out more about Pyrois here: Pyrois is an interpreted language with syntax similar to C++ and Java.
Robots use Pyrois scripting language for their code. Robots can carry boxes, use guns and swords, navigate through a maze and open doors with sensors. If there are any compilation errors in your code, game will tell you by pointing at the line, where the first compilation error occurred.
If you decide to use Notepad++ you can find syntax highlighter in "scripts/notepad++pyrois".Īfter you write code, you can assign it to your robots and watch them do, what you told them to do. The best code editor you can get for Virtual Robots is probably Notepad++. Ironically, this game does not have a code editor. The objective of this game is to write code for your robots. Again, if you start above the first line of code that looks wrongly indented you should be able to track down your error.Virtual Robots is a robot programming simulator. You can see in the above code listing that task main() and its body are indented (pushed to the right). Unreferenced function / Undefined Procedureįrom the following code: void movForward ( float inches ) In a perfect world you should strive to have no messages at all in the Compiler Errors window pane, your code will generally be cleaner. Error something is broken and you need to fix it.The compiler is pretty sure you wanted to use it, but you’re not. You write a function moveForward(float inches) but it’s not being used. Warning the compiler is pretty sure this thing will cause a problem, just maybe not right now.Maybe you defined a variable to use somewhere else, but deleted that other code, so that variable is hanging around for no reason. These messages are really just to help you keep your code clean, as far as the compiler can tell they don’t have the potential to cause any problems. Info nice to know information that the compiler discovered.Let’s quickly chat about the various Message Types: What type of message this is (Error, Warning, Info).What line number the compiler is talking about.Looking at the above screenshot there’s actually a lot of information there: First let’s look at where you can find your compiler messages:Ĭompiler Messages show up in a window pane at the bottom of the ROBOTC IDE. Sometimes the messages you get back from the compiler aren’t completely obvious, but the more familiar you get with them the easier it’ll be to figure out what’s wrong with your program. Here’s the sign that you did something wrong: Compiler ErrorsĬompiler Errors will, unfortunately, be a fact of life as a programmer. Once you’ve found it, then look at the details for that section and most importantly the FIX listed in each section. Scan through the headings (they’re underlined) and see if you can match up a few of the words.A program’s code is the text that is written in it. A robot’s commands are written as text on the screen, processed by the ROBOTC compiler, and loaded into a machine language file, where they can be run by the robot.
In order to make you more self sufficient, and to save my sanity :), here are a list of things I expect you to check before you ask me or your teammates for help.
