ROBOTC FUNCTIONS CODE

You write a function moveForward(float inches) but itРІР‚в„ўs 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 donРІР‚в„ўt have the potential to cause any problems. Info nice to know information that the compiler discovered.LetРІР‚в„ўs 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 thereРІР‚в„ўs actually a lot of information there: First letРІР‚в„ўs look at where you can find your compiler messages:Р”В¬ompiler Messages show up in a window pane at the bottom of the ROBOTC IDE.

Sometimes the messages you get back from the compiler arenРІР‚в„ўt completely obvious, but the more familiar you get with them the easier itРІР‚в„ўll be to figure out whatРІР‚в„ўs wrong with your program. HereРІР‚в„ўs the sign that you did something wrong: Compiler ErrorsР”В¬ompiler Errors will, unfortunately, be a fact of life as a programmer. Once youРІР‚в„ўve found it, then look at the details for that section and most importantly the FIX listed in each section.

Scan through the headings (theyРІР‚в„ўre 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 youРІР‚в„ўre looking for (Starting from the first compiler message): VEX File ManagementFrom the file management utility, you can.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. Returns a true if there is space available, false if the queue is full.VEX File ManagementThe file management utility allows you to see all of the programs, sound files and other files that are loaded on your VEX.

Set bPlaySounds to true to unmute the VEX.The #define shortcuts are also acceptable: MuteSound() UnmuteSound() Sound QueueThe VEX has an internal queue in order to line up sound commands.This queue will automatically process any waiting sound commands, in order that they are received.You can override/check on the queue with the following commands:PlayImmediateTone(frequency, durationIn10MsecTicks) This command will force the playTone command to jump ahead of the queue.bSoundQueueAvailableA Boolean Variable to check if the sound queue is full. Set bPlaySounds to false to mute the VEX. Returns true if a sound is playing, false if no sound.bPlaySoundsA Boolean variable to mute the VEX. Use the File Management Utility for downloading sound files onto your VEXRobot Advanced Tools File ManagementPlaying SoundsPlaySound(sound) Plays a specific sound effect that is pre-programmed into the VEXsoundBlipsoundBeepBeepsoundDownwardTonessoundUpwardTonessoundLowBuzzsoundFastUpwardTonessoundShortBlipsoundExceptionsoundLowBuzzShortSound VariablesbSoundActiveA Boolean variable informs the user if the VEX is actively playing a sound.

ROBOTC SoundsROBOTC with the VEX has a speaker port available on it for playing basic and polyphonic tones.You can play the follow types of sounds:A specific note PlayTone() A system sound PlaySound() A user loaded sound file (.wav) PlaySoundFile()
