Re: [Tutor] a pyball python app
Dean, Here's a tutorial/book that you should check out: http://www.greenteapress.com/thinkpython/ How to Think Like a (Python) Programmer by Allen B. Downey He generously has a free PDF to download, and the book makes use of some code - swampy.py I think if you 1) Read the book and try the examples, and at least try /some/ of the assignments, and 2) Examine the source code of the swampy program, you'll learn how to do exactly what you want - create two different balls (or technically, as many as you'd like/the phone will run).

Re: [Tutor] Which Python Script Editor of Choice?
Asking a programmer which editor to use is like asking which religion is best. I use VIM and IPython and shell scripts (I mostly program on windows, but sometimes on Linux as well). There are several options. I'm considering looking into PIDA, which is a "IDE you make from tools you already use" but haven't had time to try to check it out on windows. Eric4 and Wingware are both very fully developed. Komodo also often gets props from the "IDE People" I've known. Other "IDE" choices go as follow, DrPython, pyCrust, emacs, VIM (has IDE addons), IronPython/VisualStudio, Boa Constrictor, and Eclipse. I do often suggest to people who are just starting out: Learn to program without an IDE, then use one after 6 mo/a year. Many people who go this way, program with or without one just fine. Those who start right away always using IDE's can just plain die when they hit an environment where they don't have one (due to time, money, location, or whatever). Btw, if people know of good IDE's other than PIDA that are free, run on windows and linux and allow use of VIM as the editor, please let me know. --Michael On Thu, Apr 3, 2008 at 11:32 AM, Jeffrey Dates <[EMAIL PROTECTED]> wrote: > Hello, > > So as I'm starting to get into writing some scripts, I'm looking for > recommendations for a nifty script editor.

Or for a simple editor you can use Scite which is the same editor engine as Pythonwin but includes multiple tabbed panes. But doesn't include an interactive shell. At the other end of the scale you can install PyDev into the eclipse editor which is a good solution if you already use Eclipse for anything else. emacs and vim can both be made Python aware too.

For a very simple example of using a socket you could try the Network Programming topic in my tutorial. There is also a HowTo or Topic guide on the Python web site that gives a more detailed example. That having been said, backups are usually best done using OS tools or if you must roll your own then using ftp or similar as a file transfer mechanism rather than trying to send a bytestream over a socket. ftp can handle broken connections etc more easily.

Re: [Tutor] a pyball python app
this is the part im lil confused about to add the extra ball location=[img.size[0]/2,img.size[1]/2] speed=[0.,0.] blobsize=16 xs,ys=img.size[0]-blobsize,img.size[1]-blobsize acceleration=0.05 friction = 0.993 import time start_time=time.clock() n_frames=0 i tried copying but it did nothing do i need to copy it and change something so the python app dont read the same txt twice and jus do nothing? also on the txt bellow if i add another bal somehow i dotn have to copy or change the txt bellow do i? it should create same value for both balls? x_bounce_factor = .8 * (1 - min(6,abs(sense_conn.delta[0])) / 9) y_bounce_factor = .8 * (1 - min(6,abs(sense_conn.delta[1])) / 9) if location[0]>xs: location[0]=xs-(location[0]-xs) speed[0]= -x_bounce_factor * speed[0] speed[1]=0.90*speed[1] if location[0]<0: location[0]=-location[0] speed[0]= -x_bounce_factor * speed[0] speed[1]=0.90*speed[1] if location[1]>ys: location[1]=ys-(location[1]-ys) speed[0]=0.90*speed[0] speed[1]= -y_bounce_factor * speed[1] if location[1]<0: location[1]=-location[1] speed[0]=0.90*speed[0] speed[1]= -y_bounce_factor * speed[1] im just confused on how to get the programme to add another ball into it and keep everything the same.. i tried changing and copying some of the script but the app jus loads the whole ball script twice and seperate ball on each. also could you link advise any good tuturials that would help me ive read some on the net but need more help really. thank you for your time. . > Date: Thu, 3 Apr 2008 10:16:37 -0400 > From: [EMAIL PROTECTED] > To: [EMAIL PROTECTED] > CC: tutor@python.org > Subject: Re: [Tutor] a pyball python app > > dean garrad wrote: > > i kind of understood what you were saying but not sure how to go by this > > i am still new to python script and learning it as much as i can. > > OK.

i kind of understood what you were saying but not sure how to go by this i am still new to python script and learning it as much as i can. here is a video of the script in action http://youtube.com/watch?v=zqZeANFBmis i did not create the script only trying to modify it. i have permission from the developer to modify. > Date: Thu, 3 Apr 2008 08:57:05 -0400 > From: [EMAIL PROTECTED] > To: [EMAIL PROTECTED]; tutor@python.org > Subject: Re: [Tutor] a pyball python app > > dean garrad wrote: > > > this one is the working version of 1 ball that can move around the > > screen im sorry the other one i sent was a test one ive been trying out.. > > > > i cant seam to find it as easy to get it to work with 2 balls on screen. > > anything i try doesnt effect the script. > > What have you tried?

Do you understand how the current script works? If not, what parts are confusing? Do you understand object-oriented programming at all (classes)? If not, you should probably read some tutorials and get at least a basic understanding. You could add another ball by brute-force copying of lots of code, or by making a list of (location, speed) values for each ball, but the code will end up simpler and easier to understand if you use a class to hold the parameters for the ball.

The attachment seems to be a modified version that moves text around on the screen, not a ball. The program uses global variables to hold the state of the moving image, in particular the lists that hold location and speed. Adding a second image while keeping the same programming style would involve a lot of code duplication. What I suggest is to create a Ball object that holds the location and speed of the ball. The movement code could also go into the Ball class. Get this working with one ball. Then it should be pretty easy to add a second ball.

hi there.. im not sure if you can help or you would want to but i fort i may aswell give it a try. i am currently trying to edit a python app it is a normal green ball game that comes with python it uses nokia n95 accel to move around. i have been trying to make more than one ball on the screen at the same time . do you think it is possable ? i have attached the script to this e mail and would be greatful for any advice thanks. dean. _ Amazing prizes every hour with Live Search Big Snap http://www.bigsnapsearch.com# This code has been significantly modified from the original source, which # is distributed with Nokia's Python for Series 60, by Christopher Schmidt, # and is released under the same license as that code (see below). # # Copyright (c) 2008 Christopher Schmidt # Copyright (c) 2005 Nokia Corporation # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License. import appuifw from graphics import * import e32 import sensor class SensorConnection(object): delta = [] def __init__(self): """Connect to the sensor.""" sens = sensor.sensors()['AccSensor'] self.s = sensor.Sensor(sens['id'], sens['category']) self.s.connect(self.callme) def callme(self, state): self.delta = [] for key in ['data_1', 'data_2', 'data_3']: val = state[key] self.delta.append(int(val + 40)/80) def cleanup(self): """Cleanup after yourself. *Must be called* before exiting.""" self.s.disconnect() sense_conn = SensorConnection() appuifw.app.screen='full' img=None def handle_redraw(rect): if img: canvas.blit(img) appuifw.app.body=canvas=appuifw.Canvas( redraw_callback=handle_redraw) img=Image.new(canvas.size) running=1 def quit(): global running running=0 appuifw.app.exit_key_handler=quit location=[img.size[0]/2,img.size[1]/2] speed=[0.,0.] blobsize=16 xs,ys=img.size[0]-blobsize,img.size[1]-blobsize acceleration=0.05 friction = 0.993 speed=[0.,0.] blobsize=16 xs,ys=img.size[0]-blobsize,img.size[1]-blobsize acceleration=0.10 friction = 0.999 import time start_time=time.clock() n_frames=0 # To speed things up, we prerender the text. labeltext=u'Tilt the phone to move' textrect=img.measure_text(labeltext, font='normal')[0] text_img=Image.new((textrect[2]-textrect[0],textrect[3]-textrect[1])) text_img.clear(0) text_img.text((-textrect[0],-textrect[1]),labeltext,fill=0xff,font='normal') while running: img.clear(0) img.blit(text_img, (0,0)) img.point((location[0]+blobsize/2,location[1]+blobsize/2), 0x00ff00,width=blobsize) handle_redraw(()) e32.ao_yield() e32.reset_inactivity() speed[0]*=friction speed[1]*=friction location[0]+=speed[0] location[1]+=speed[1] n_frames+=1 if not sense_conn: continue if not len(sense_conn.delta): continue x_bounce_factor = .8 * (1 - min(6,abs(sense_conn.delta[0])) / 9) y_bounce_factor = .8 * (1 - min(6,abs(sense_conn.delta[1])) / 9) if location[0]>xs: location[0]=xs-(location[0]-xs) speed[0]= -x_bounce_factor * speed[0] speed[1]=0.90*speed[1] if location[0]<0: location[0]=-location[0] speed[0]= -x_bounce_factor * speed[0] speed[1]=0.90*speed[1] if location[1]>ys: location[1]=ys-(location[1]-ys) speed[0]=0.90*speed[0] speed[1]= -y_bounce_factor * speed[1] if location[1]<0: location[1]=-location[1] speed[0]=0.90*speed[0] speed[1]= -y_bounce_factor * speed[1] speed[0] -= (sense_conn.delta[1]) * acceleration speed[1] -= (sense_conn.delta[0]) * acceleration speed[0] = max(min(xs / 2, speed[0]), -xs/2) speed[1] = max(min(ys / 2, speed[1]), -ys/2) end_time=time.clock() total=end_time-start_time sense_conn.cleanup() print "%d frames, %f seconds, %f FPS, %f ms/frame."%(n_frames,total, n_frames/total, total/n_frames*1000.) ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
