#Robotc while loop code

Multiple If-Else StatementsIn this example, if one of the touch sensors is pressed, the rightMotor will be turned on in one if-else statement and immediately turned off in the other Multiple If-Else StatementsBe careful when using two separate if-else statements, particularly if both are used to control the same mechanismOne branch of each if-else statement is always run so that you may create a scenario where the two statements fight one another

#Robotc while loop code

If-Else StatementsIf-else statement is an expansion of if statementIf checks condition and runs appropriate commands when it evaluates to trueElse allows code to run when condition is falseEither if or else branch is always run once Presentation NameCourse NameUnit # Lesson #.# Lesson Name10If StatementsIf statement in the program is evaluated by condition contained in parenthesisIf condition is true, commands between braces are runIf condition is false, those commands are ignoredVery similar to how a while loop works, but does not repeat the code More information available at the Cortex Video Trainer Resource. TimersLoop controlWhere would the wait statement go if we wanted the loop to repeat for a controlled amount of time?Nowhere! We need something else.Solution: TimersInternal stopwatches (4 available)Like encoders, timers should be cleared before they are usedBecareful where you clear timersClearing timers within a loop may continually reset the timers which may create an infinate loop.Presentation NameCourse NameUnit # Lesson #.# Lesson Name9TimersTimer T1 is used as the condition for the while loop, which will run for 30 seconds Commands to be RepeatedCommands between curly braces will repeat while condition is trueProgram checks at the beginning of each pass through the loopīoolean LogicProgram decisions are always based on questionsOnly two possible answersyes or notrue or falseStatements that can be only true or false are called Boolean statementsTheir true-or-false value is called a truth value. The ConditionCondition controls how long or how many times a while loop repeatsWhen condition is true, the while loop repeatsWhen condition is false, the while loop ends and the remainder of the program executesĬondition is checked every time loop repeats before commands between curly braces are runģ.

The Word WhileEvery while loop begins with the keyword WhileĢ.
