This version does not require an Internet connection to install or activate.This is a Periodic Building license of ROBOTC Robot Virtual Worlds for version 4.0 and any hot-fix updates (minor fixes and bug fixes).Again, if you start above the first line of code that looks wrongly indented you should be able to track down your error.ROBOTC is a cross-robotics-platform programming language for popular educational robotics systems. 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.Press CTRL+F and type a word or two in that box to search (use the most unique word in the compiler message).Two ways to find what you’re looking for (Starting from the first compiler message): 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.
