Fix the find failed issue in sikuli script

Question

I have the following code that always returns a findfailed error when it doesn't find the end_turn image.

def clickCards():
    # region.wait(end_turn,90)
    # search for the cards and click all of them
    if exists(zero):
        z = region.findAll(zero)
        for i in z:
            click(i)
            sleep(1)
    else:
        pass
                     
    if exists(one): 
        o = region.findAll(one)
        for i in o:
            click(i)
            sleep(1)
    else:
        pass

    click(end_turn)

while exists(level):
    
    with region:
        
        if exists(end_turn):
            clickCards()
        elif exists(victory):
           click(victory)
        else:
            wait(end_turn,90)

I am trying to automate the following game visual:

• Card Games starts
• click cards while end button is available
• end turn with end turn button
• keep playing until I win
• Victory appears and no end turn button is visible anymore
• click the victory image

The script will run, but when I win it will go into an error that it couldn't find the end_turn button.

I had a similar issue. Luckily the docs are good in this case. https://sikulix-2014.readthedocs.io/en/latest/region.html#exceptionfindfailed

Its by design that region.findAll() will raise a FindFailed exception when it cannot find a match (implicit or explicit). In your case, I think its the implicit call during the click() operation.

Fortunately, Sikuli gives a way out by letting one toggle this exception.

You can use setThrowException() to toggle this exception for a region.

def clickCards():
# region.wait(end_turn,90)
# search for the cards and click all of them
region.setThrowException(False)
if exists(zero):
    z = region.findAll(zero)
    for i in z:
        click(i)
        sleep(1)
else:
    pass
                 
if exists(one): 
    o = region.findAll(one)
    for i in o:
        click(i)
        sleep(1)
else:
    pass

click(end_turn)
