How to set speed depending on button pressed

[rcodecom]

Hi, I am looking at the code on this page for the 42109 rally car:

Everything works fine, but I would like to use the red left button to set the speed to 50%, and use the red right button to set the speed to 100%. Rather than having the speed change while the buttons are pressed, I would like just a press of the button to change the speed to the new value where it would remain until the other button is pressed.

How can I do this?

Something like this?

    if Button.LEFT in pressed:
        drive_speed = top_speed // 2
    if Button.RIGHT in pressed:
        drive_speed = top_speed

Totally right, I missed that. Works beautifully now, thank you.

As a sidenote, I did have some problems updating the code on the hub after changing some of it as indicated. I had to reset the hub and install the bootloader again, then download the new code for it to be applied. Maybe a bug of sorts with the current version of pybricks.

Did you use https://code.pybricks.com/ or https://beta.pybricks.com/ when this issue happened?

For issues with updating code, I suggest trying it out with https://beta.pybricks.com/

We have improved program storage a lot. Resetting/updating is no longer required to save a program. Just run it and it will be saved.

I understand you're experiencing issues with the beta in terms of Bluetooth, however. We're looking into it.

Thanks for taking the time to report your issue here, we really appreciate it :)
