Idea for multiple keys pressed

[borisreyesgrange]

Hi, I'm using your pygamge_function with my High School Computer Science students in Chile, and I want to share with you this idea... I take your keyPressed function and add a simple modification to add multiple keys detecting (for jumping with direction for example, or move in diagonal):

KeyCheck must be a list with the keys to check

def keysPressed(keyCheck):
global keydict
pygame.event.clear()
keys = pygame.key.get_pressed()
pressedKeys = 0
if sum(keys) > 0:
for key in keyCheck:
if key == "" or keys[keydict[key.lower()]]:
pressedKeys += 1
if pressedKeys == len(keyCheck):
return True
return False

When we use this, in the game loop, we must check the multiple keys pressed actions first, before of the single keystroke in the "if" that controls the movement.

An interesting idea.
So would you be using a line of code such as:

if keysPressed(["up","left"]):
    # actions for diagonal left
elif keysPressed(["up","right"]):
    # actions for diagonal right
elif keyPressed("up"):
    # just up

In which case, doesn't this do the same:

if keyPressed("up"):
    if keyPressed("left"):
        # Diagonal left
    elif keyPressed("right"):
        # Diagonal right
    else:
        # Just up
