The 2019 update to the MakeCode editor (makecode.microbit.org) contains a number of new features and bug fixes that we'd like you to test.
Functions with parameters
You can now pass parameters to functions. This example passes two numbers as parameters and then displays them on the LED display.
The green screen lets you use your web camera or a green screen as the background to the workspace. Using screencapture software, this allows you to record demonstrations or tutorials in the editor. It can be enabled in the settings menu.
The home screen now includes the ability to search for, duplicate, delete and list your projects. Handy if you have lots of projects saved in the browser.
UTF8 character support in strings
Updated servo blocks
The blocks in the Servo extension have been improved to help you calibrate and better control your servo motors
Updated radio receive blocks
Previously if you renamed the values in Radio Received blocks the data types would not change; ie string remained string and number remained number.
To resolve this, we are now using fixed names for the received values – so they will not show up in the Variables Toolbox drawer and you will not be able to rename them.
Convert to String
The Convert to String block can take numbers and Boolean values and convert them into Strings.
A ‘Garbage collector’ has been introduced to improve memory usage. From MDN “High-level languages embed a piece of software called "garbage collector" whose job is to track memory allocation and use in order to find when a piece of allocated memory is not needed any longer in which case, it will automatically free it”.
