Change motor speed

[WonderBoii]

how can I code when I pressed a button change my motors speed and when I pressed another button it would go back to its regular speed?

[Deicer]

if button pressing, var = low
if button2 pressing, var = not low
motor spin at power var

[WonderBoii]

my bad I wasn’t clear I meant if buttonA.pressed how would I use that to change the speed

{i’ll rewrite my question}

[Deicer]

if buttona.pressing()
speed
if not
don’t speed

The .pressed() method is probably what you would want to use. You can have a variable that stores the speed, read when the button is pressed, and swap the speed. The .pressed() method runs once after the button has been released, meaning you won’t loop swapping the values.

how can I use the pressed method

Please, be aware that .pressed() function uses callbacks and is only good for advanced coders. It is very easy to mess up with callbacks.

If you decide to use .pressed() instead of much simpler .pressing() function, then you can find very helpful this mini-tutorial:

How do I use the controller button pressed command

yea, this is used when polling the button, it returns a boolean indicating if the button is currently pressed or not. Controller1.ButtonA.pressing() These are used when you want your code to be event based. Controller.ButtonA.pressed( callback_pressed ); Controller.ButtonA.released( callback_released ); A callback used an an event is running in its own thread, that means you can block using time consuming code or a while loop if you really want to, for example, this code using namespace…
