Robotc if else how to#
What the above sample translates to is: motorįor kids who are programming novices, I would not recommend this style of writing instructions, as it can make it difficult to find errors when there’s so much going on in just one line of code (and then throw in multiple programmers at varying skill levels, and … probably a mess). But that doesn’t mean that they (and you) shouldn’t know how to read this code so that you can learn from the vast quantities of information and sample code available on the VEX Forum and the RobotC Forum.įor kids who already have some programming experience under their belts, this can be a great next step in sophistication, especially when your overall program is becoming more complex and, therefore, longer. This particular ternary sample is a way of connecting motor2 to joystick Channel 3, including a deadband area of ☑0 (in RobotC “abs” refers to “absolute value”). The word while Every while loop begins with the keyword while. This structure is called a “ternary” operator ( ternary = comprised of 3 parts), and it is a way of having an if-else statement all in one line. While loops While loop is a structure within ROBOTC Allows a section of code to be repeated as long as a certain condition remains true Three main parts to every while loop 1. Click File, Save As, select the folder that your teacher designated, and then name the file A125Part4. With this command the computer will execute one of two pieces of code, depending on whether the condition is true or false. It turns out that these statements are actually pretty cool. An if-else Statement is one way to allow a computer to make a decision.
If you’re like me in the early stages of learning RobotC, at this point your eyes glaze over and you think something like, “This is too complicated, I’ll look for another answer somewhere else.” is a little more my style, so I am not sure how they. If you’re new to RobotC and searching for sample code or explanations, you will frequently run into statements that look very confusing, involving a question-mark (?) and a colon (:), such as: motor = abs ( vexRT ) > 10 ? vexRT : 0 Pamela explains how to use mouseIsPressed with if statements to execute code.
