# script: RegionAreaTest6, 01 June 2013
# Related to [Question #229825]: do an action if the image on a region doesn't change
# This Sikuli script monitors a screen area to detect change.

bigChange=False  # a global variable set if a region changes

def changed(event): # this function runs if change is observed
        print "something changed in ", event.region
        global bigChange # set to true if this function runs
        bigChange=True
        print bigChange
        for ch in event.changes:
                ch.highlight(2) # highlight all changes
        sleep(1)
        for ch in event.changes:
                ch.highlight() # turn off the highlights
        event.region.stopObserver()


# now start watching a Chicago Transit Authority map of buses moving down streets
# http://ctabustracker.com/bustime/map/displaymap.jsp

print "Starting..."
myRegion=Region(200,250,500,500)  
# adjust size of region examined, make area as small as reasonably possible to limit searching, analysis

#myRegion=Region(420,270,200,200) # an alternative region that is smaller
myRegion.highlight(3)  # for illustrative purposes, not functionally necessary
wait(1)
myRegion.highlight(0) #remove highlight
wait(1)
print bigChange # value of the variable before starting the monitoring

myRegion.onChange(30, changed) # install 'changed' as the function to run if changes are discovered
myRegion.observe(30,background=True) # start observing for 30 seconds before proceeding
# Monitoring is now running.
# Next start a loop to check for changes in the monitored area...

myLimit=4
i = 0  # index for our loop
mycontinue = True
print "Starting mycontinue loop..."
while mycontinue:
    print bigChange
    if bigChange:

    else:
        print "No change yet."
        # Do some desired action here...
    i +=1 # increment index 
    if i >=myLimit:
        mycontinue=False
    wait(5)
