OBSERVE(FOREVER) but FINDFAILED

Asked by Alexandre Bourdeau

Hello, first post here. This is my code:

def myH(e):
 hover(PICTURE)
 stopObserver()
 observe(FOREVER)

onAppear(PICTURE, myH)

observe(FOREVER)

After some time it stops and I get the following message:

[error] Message d'erreur : Traceback (most recent call last):

Line 6, in file C:\Users\ALEXAN~1\AppData\Local\Temp\sikuli-tmp4889400881574180526.py

Why am I getting this error? All I want to do is to make a script that hovers over a picture when it appears with an endless loop.

Thanks for the help.

In any case: You cannot start a new observe() inside the handler.

*** So your basic code should be:

def myH(e):
 hover(picture)
 stopObserver()

picture = "your-captured-image.png" # only one capture / multiple use
onAppear(picture, myH)

observe(FOREVER)

*** So if you want this to continue this for ever:

def myH(e):
    hover(picture)
    stopObserver()

picture = "your-captured-image.png" # only one capture / multiple use
onAppear(picture, myH)

while True:
    observe(FOREVER) # this will start observing again, when handler has stopped the observer

But this does not make sense, because I cannot see any action to wait until the image disappears to start a new observation.

*** do not make another find in the handler
in the handler, you know the match of the onAppear(), so you can use:

def myH(e):
    hover(e.match)
    stopObserver()

(look: http://sikuli.org/docx/region.html#observing-visual-events-in-a-region)

*** using exists() instead of observe()
for these situations (observing in foreground - script waits) I prefer to use loops and exists()

picture = "your-captured-image.png" # only one capture / multiple use

while True: # run forever
    while not exists(picture, 0): # wait for picture
        wait(1)
    hover(getLastMatch())
    wait(10) # or something else to make picture vanish
