Speeding up CV on PC with emulator?

[savour]

I have been working on a Vagrant story auto chain script, and have noticed sometimes the delay between CV recognizing the chain ! and GPCinputting the button is too long leading to it not working.

For those who don't know, Vagrant story has a chain system that works similar to rhythm games where an ! comes up, and then you must press some button (square, triangle or circle) immediately after that. If done correctly it will continue the combo until the user misses a prompt, or the enemy dies. Here is a youtube video of someone getting a 30 chain to show how it works.

At first my script was too slow 100% of the time since I was checking the entire frame the ! but after cropping the frame to a zone that the ! pops into most the time it now works about 70% of the time. I'd like to make it perfect, so if there are any other things I can do to make this quicker or strategies people have used to make rhythm type mechanics work correctly that would be greatly appreciated!

Here is an image of the cropped image that is currently being checked. The blue square is the same size as the image being checked for the !

Any help or feedback greatly appreciated! Thanks!

GCV code

Code: Select all

 
    def process(self, frame):
        self.gcvdata[0] = False
        frame = cv2.rectangle(frame, (700,100), (1400,500), (255, 0, 0), 2)
        picture = frame[100:700, 500:1400]
 
        # Passing bools to GPC script to take action on.
        self.gcvdata[0] = self.imageMatch(picture, self.attack_combo, 0.97)
 

GPC code

Code: Select all

 
if (enabled) {
        if(gcv_ready()) {
            attack_combo = gcv_read(0);
        }
 
        if(attack_combo) {
            // left hold to trigger square combo
            if(get_actual(BUTTON_12)) {
                combo_run(square);
            }
            // up
            else if(get_actual(BUTTON_10)) {
                combo_run(triangle);
            }
            // right
            else if(get_actual(BUTTON_13)) {
                combo_run(circle);
            }
            else {
                combo_run(circle);
            }
        }
