You can change the name of a Control Hub using a laptop or Chromebook that is connected to the Hub's Program & Management page.

In order to comply with game manual rule, the name should be changed. Examples follow below.By default, the Control Hub has a name that begins with the phrase 'FTC-' and ends with four characters that are assigned at the factory. All very useful! Your myBlock method can directly use objects or instances of these classes without declaring them. Programming note: classes inherited from BlocksOpModeCompanion include OpMode, LinearOpMode, Telemetry, HardwareMap, and Gamepad.

When you enter that line, the OBJ software automatically creates an import statement, making the parent class available.

The parent class BlocksOpModeCompanion contains useful tools to be inherited by your new subclass. This declares your new class as a subclass or child of a higher superclass or parent. Your pets Spot and Rover would be objects or instances of the 'dogs' class.Īfter the class name, type extends BlocksOpModeCompanion. A class called 'dogs' might contain methods 'run' and 'sleep', and fields 'friendliness' and 'appetite'. Programming note: A class describes methods (actions) and fields (properties) that can be used by objects (examples or instances of the class). and will thank yourself later for commenting heavily! Good programmers use lots of comments, to communicate with your FTC teammates and with your future self! You will not remember every little detail of your programs. The two forward-slash marks // indicate a comment line, all ignored by the Java software.

Place all your code between these curly braces. Notice the left curly brace at Line 4 and right curly brace at Line 7. It's public so other classes can access it. Line 1 shows the default storage folder 'teamcode', and Line 4 shows the class name, same as the filename. In the work area you see a simple/empty Java program. Don't choose a Sample OpMode, and use the default setting 'Not an OpMode'. Use the default 'teamcode' folder location. If you need internet and FTC programming together, connect an Ethernet cable to an internet router or try adding a USB Wi-Fi dongle.Ĭlick the large plus-sign icon to open a new file call it SampleMyBlocks.java. To follow this tutorial while programming, first allow this single web page to load completely, then connect to the Control Hub or RC phone. Note: a computer can usually connect to only one Wi-Fi network at a time. Go to the address (CH) or (RC), and click the OnBot Java tab. Open a Chrome browser connected via Wi-Fi to a Control Hub or RC phone. Start with a simple myBlock that creates a greeting 'Hello World' (of course!). This tutorial does not teach Java or OnBot Java (OBJ), beyond the bare minimum needed for basic myBlocks.Students already using Android Studio can easily follow the same programming. This tutorial builds myBlocks with OnBot Java, a programming tool running on the Control Hub or Robot Controller (RC) phone.Hats off to Google engineer Liz Looney for this major development! Notes on Java The other team members can continue learning and working in Blocks, producing the team's official code. Sample myBlock: return encoder target value based on inputsĪlso, myBlocks programming allows some team members to begin learning and using Java, contributing valuable new features. Now your team's Blocks code can be more powerful, and simpler! Or, a single myBlock can serve as a 'super-Function', containing robot instructions that previously needed many regular Blocks. Sample myBlock: operate a servo, no value returnedĪ myBlock can add advanced capability previously available only to teams using all-Java code. These 'myBlocks' are programmed in Java, with OnBot Java or Android Studio.

This tutorial shows how to make custom FTC Blocks, to be used in regular Blocks programs.
