Here's an example: UP = 0DOWN = 1
LEFT = 2RIGHT = 3
keys = [0, 0, 1, 0] #up, down, left, and right keys, respectively. 0 stands for 'not pressed', 1 stands for 'is pressed'.
if LEFT in keys: print True
Now, it won't work, because "2" is not in the keys list. if keys[LEFT]:
print TrueThis works, because you're checking to see if the 3rd numeral in the list is positive/true. HTH On Wed, Feb 11, 2009 at 5:46 PM, Yanom Mobis <yanom@xxxxxxxxxxxxxx> wrote:
Hmm. now i remember how it's done. the part about pygame.key.get_pressed returning 1's and 0's makes sense, but I just don't get why
if key[K_UP]:
works if
if K_UP in key:
doesn't.

hi,
K_UP has the value 273 and pygame.key.get_pressed() returns a tuple where the n'th value is 1 if the n'th key was pressed.
This should work:
if key[K_UP]: .....
