update() required to read controls?

Wanderer1412

I thought the update() function was to update the screen graphics.... but it seems it's also required to read the controls?

If I want to wait for the "A" button to be pressed, then this works...

c=controls(0)
while not c.a loop
     c=controls(0)
     update()
repeat

But, if I miss out update()....

c=controls(0)
while not c.a loop
     c=controls(0)
repeat

...then I get "Stack overflow. Too many functions called, maximum memory for variables exceeded (line 3)"

update also polls input internally, so you're correct- it is required for this!
