[[SIGVerse with Python]] The aim of this tutorial is to --write a python module using pygame that captures mouse movements --to present setting of environmental variables for writing Sigservices in Python --import the module inside Sigservice and send data to Sigserver --making a .sig file and loading it into Sigviewer To use this tutorial, the use needs to have boost.python libraries installed and configured on his visual studio project. I have shown how to do that in previous tutorial. -Writing python module for capturing mouse movements using pygame --Please install pygame from [[here:http://www.pygame.org/download.shtml]]. The version I am using is pygame-1.9.1.win32-py2.7.msi. It should be set in your python path. --Please install pygame from [[here:http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygame]]. The version I am using is pygame-1.9.1.win32-py2.7.msi. If you use 32 bit python, please use 32 bit version of pygame. It should be set in your python path. --Please copy the following code and name it as "mouseModule.py" #highlight(python){{ import sys import time import threading import pygame from pygame.locals import * pos=[] class App: def __init__(self): self._running = True def on_init(self): # pygame.init() # self._display_surf = pygame.display.set_mode(self.size, pygame.HWSURFACE | pygame.DOUBLEBUF) screen = pygame.display.set_mode((620, 400)) self._running = True self.flag=0 def on_event(self, event): if event.type == pygame.QUIT: self._running = False def on_loop(self): pass def on_render(self): pass def on_cleanup(self): pygame.quit() def on_mouseMotionNew(self): background_colour = (255,255,255) screen = pygame.display.set_mode((620, 400)) screen.fill(background_colour) flag=0 running=1 num=[] # pos=[] posAbs=[] posRel=[] global pos while running: event = pygame.event.poll() if event.type == pygame.QUIT: running = 0 if event.type == pygame.MOUSEBUTTONDOWN or event.type == pygame.MOUSEMOTION: (a,b,c)= pygame.mouse.get_pressed() if a == 1: print "the left button is pressed, logging starts" # print "mouse at (%d, %d)" % event.pos flag=1 count=0 elif c==1: print "the right button is pressed, logging stops" flag=0 flagList=[flag] yield flagList if event.type == pygame.MOUSEMOTION and flag==1: # print "mouse at (%d, %d)" % event.pos # pos=list(event.pos) count=count+1 pos=list(pygame.mouse.get_rel()) # print "relative pos is (%d, %d)" % pygame.mouse.get_rel() # num.append(pos) pygame.draw.circle(screen, (0,0,240),event.pos, 3,1) pygame.display.flip() if count==1: pass else: yield pos pygame.quit() # return num if __name__ == "__main__" : theApp = App() a=theApp.on_mouseMotionNew() for i in range(0,100): # Please modify this value to change the number of iterations. print next(a) pygame.quit() }} When you run this code, it captures 100 mouse movements and captures the relative distance between successive mouse movements. To change the iteration from 100 to some other number, please modify the counter. We shall now be importing this user defined module in our code. -Create a Visual Studio project --I have used Visual Studio 2008. --Please use Ctl+Shft+N to create a New Project. Lets call it "My Service Test". -Setting environmental variables. You need to have SigService library on your disk. Please download it from [[here:http://www.sigverse.org/wiki/en/index.php?service%20libraries]] I am using SIGService_v2-1-0 and its location on my disk is at F:\Sigverse\SIGService_v2-1-0\SIGService_v2-1-0 --1.

Please load the world file sigserver.sh -w ./ToolsOnTable.xml -p write_your_port_number 5. Go to Services-->Add-->MyServiceTest.sig and then Services-->Start This shall add your mouse service. 6. Please click "Start" to run the simulation. 7. When you use left click the mouse events are captured and their relative positions are recorded. Based on these relative positions, the tool moves which hits the target object. On making right click, the event capturing is stopped. #highlight(end) #counter
