is pressed vs. was pressed

jimjams — 2021-09-13 07:49:04 UTC

If you want to make sure that your condition is checked at the start of each loop, you must use was_pressed().

This is because is_pressed() is checked only once, and if you aren't pressing the button at that exact same microsecond, your program is going to miss it!
