Re: [pygame] Can the pygame infrastructure be used for non-graphical text-mode games?

[Noel Garwick]

What Ian said is totally valid.

But maybe you're wanting something like this pseudo curses implementation
in pygame..?

Re: [pygame] Delay in MOUSEBUTTONUP after application start

[Noel Garwick]

If you tie it to something other than a print statement, are you still
seeing a delay?

And maybe this is a dumb question, but are you using the same mouse when
you test on Windows and OSX? Just to rule out anything physically different
with the mouse...

Could you post the source somewhere?

I think another reason those files are staying locked could be if you

Re: [pygame] Blit method bug?

[Noel Garwick]

Hi babaliaris,

Glad to see you're trying out pygame.  Just a suggestion, but even though
you can see the code in the video, it's still a good idea to paste or
provide a link to it in your email.

This is something I've encountered before. It doesn't really have anything
to do with the number of images you're blitting (only a very small
percentage of those are even being written to the screen, see?) It's a
limitation due to the coordinates being 16-bit integers.  When those go
past  32,767 (for signed, which allow negative and positive values), it
starts back at -32,767 and continues until we hit positive values you would
see on the screen.  Since those are starting at an odd number, you end up
with the 'offset' images you see in your output.

Python 3 supports much larger numbers.  iirc, the default for an integer is
as much as a full Long -- so it should match the maximum allowable value
for your environment.  Pygame is still using 16-bit integers for blitting,
though.  One thing to remember is that all of those very large values are
wa outside the coordinates you are actually using in your display
600x600 window.  Anyway, you will want to do something like storing the
absolute location of an object and also the location (rect) of a 'camera'.
Then you can do a calculation to find where you should display the object
(if at all) by finding out where it is in relation to your camera rect.  I
usually keep track of 2 rectangles per object; a hrect (as in "hit" rect)
for absolute value / collisions, and a rect that is its location in
relation to the camera (and named 'rect' so it will be used by the sprite
group's draw method). Something like..

class Thing(pygame.sprite.Sprite):
def __init__(self, x, y):
self.x, self.y = x, y
self.image = pygame.image.load("dude.png")
self.rect = self.image.get_rect()

self.hrect = self.rect.copy()

self.hrect.topleft = self.x, self.y
...
def update(self, camera):
# logic to update self.x and self.y goes here

self.hrect.topleft = self.x, self.y
self.rect.topleft = self.x - camera.x, self.y - camera.y



Hope that helps.

Re: [pygame] Function for keyboard movement

[Noel Garwick]

Hi Bob,

There are a lot of ways to do it..

In the past, I've used something like this for teaching basic movement:


   - Store time since previous frame
   - Poll for events
  - Update held keys
   - If movement key held,
  - set movement/direction flag for player sprite
   - Update sprite ai based on time since previous frame
  - if movement/direction flag on
 - generate a rect for the proposed new location
 - see if the new location only includes non-blocked tiles
 (background collision)
- If it doesn't, this is our sprite's new rect
- If it does, either
   - do nothing (very basic) or
   - move to the edge of the original position

This should work fine for objects that won't move fast enough to cover more
than a tile per frame..

Is that what you were looking for?  Or something even more abstracted like..

while True:
tts = fpcClock.tick( FPS )

held_keys = update_keys()

draw_background()

update_sprites( tts, held_keys )

draw_sprites()

pygame.display.update()

Thank you,
Noel

Re: [pygame] Re: Need a lot of help with 'virtual' board game

[Noel Garwick]

As Winkleink said, the Invent With Pygame stuff is awesome; tons of good
hands-on examples.  The author is very cool and will probably help you out
or recommend a blog post if you have specific questions on how something
works.  http://inventwithpython.com/

For troop movement, if you're making a grid-based game, I recommend this
tile map tutorial:  http://sheep.art.pl/Tiled%20Map%20in%20PyGame

That will help you understand how to break up an area into 'cells'.

For combat, again, you just need to break things down:


   - Characters need data for HP, Attack Power, Accuracy, Dodge Chance,
   Defense
   - Use something like:
  - # see if the attacker hits the defender (there are a LOT of ways to
  do this)
  - hit = False
  - if ( random.randint( 0, 100 ) + attacker.accuracy ) >
  defender.DodgeChance:
 - hit = True
  - # If the attack hits, lower the defender's HP, adjusting the damage
  by the defender's defense
  - if hit:
 - damage = attacker.attack_power - defender.defense
 - if damage >= 0:
- defender.hp -= damage
 - # check if the defender is dead; if so, remove hide sprite, etc.,
  - if defender.hp <= 0:
 - defender.kill()

Re: [pygame] Need a lot of help with 'virtual' board game

[Noel Garwick]

Hi Michael,

You will want to break all of these down into smaller jobs, and then break
those down further.  Have you tried making Pong yet? I know it sounds
super-simple, but by implementing Pong you actually cover a ton of concepts
that you will use when making games:


   - Player input
   - Movement
   - AI
  -  Ball
 - Increment x / y by x / y speed each frame unless collide with
 ball or collide with wall
  - Storing sprite positions
   - Storing other variables (score, etc)
   - Drawing (blitting) sprites and backgrounds to a window
   - Basic state machine (Title screen, gameplay, 'paused', game over)


All of the features you're listing for your board game uses concepts that
build off of these.

Re: [pygame] encrypt/decrypt zip/unzip

[Noel Garwick]

Diliup,

My understanding is that anything you load into memory can be dumped.  So
if you're just using this to load all game assets at startup, people could
extract the assets by duping what the interpreter has loaded into memory
(the copies of the unencrypted files).

Password protected zip would work.

You can also look into what renpy's .rpa format does.

Re: [pygame] image conversion in memory

[Noel Garwick]

since myimage is using pygame.image.load, it might be indexed?  On the
other hand, it's also possible that pygame.image.save is actually
performing some compression when it saves to a png format?  I'm not sure
offhand, but something to check out.

Re: [pygame] Fwd: Missing Module and Font

[Noel Garwick]

Diliup,

You want this one from http://www.pygame.org/download.shtml:

   - pygame-1.9.2a0.win32-py2.7.msi
    6.4MB

The freetype module is new in pygame 1.9.2, so you can't use the 1.9.1
builds.

For making it work with py2exe, after you install the above, make sure that
you are configuring it to use python2.7 32 bit and not another version on
your system.

 Dear Peter or anyone else who can help me,

 I downloaded

- pygame-1.9.2a0.win32-py2.7.msi
 6.4MB

 from the Pygmaesite and everything runs smoothly. I can comile using
 py2exe without any error. BUT I CANNOT import pygame.freetype. Gives me the
 following error.
 ImportError: No module named freetype

 Now when I download Pygame from the link below
 https://bitbucket.org/pygame/pygame/downloads

 I can do import pygame.freetype but whn I compile the program using
 py2exe I get an error
 import pygame._view error. module not found.

 Please help as this is causing a LOT of preoblems and I am stuck
 between the view module and the freefont. Kind of uncomfortable here so
 please help me.

 Thank you very much in advance.

Re: [pygame] OpenGL stretch of a pygame.Surface

[Noel Garwick]

vertpingouin,

If you are doing that every frame as part of the sprite's .draw or .update
method , it's still possible the transform is what is taking up CPU time.
 You may want to use something like this instead:

class MySpriteThing( pygame.sprite.Sprite):
image = None
def __init___( self ):

.
if MySpriteThing.image is None:
MySpriteThing.image = pygame.image.load( "foo.png" )
size = MySpriteThing.image.get_size()
new_width = size[0] * X_SCALE # where X_SCALE is the ratio
between RESOLUTION_X (the big resolution) and GRAPHICS_X (the resolution
the images were made at) ; ( 1920 / 640 )
new_height = size[1] * Y_SCALE
MySpriteThing..image = pygame.transform.scale( self.image, (
new_width, new_height ) )

self.image = MySpriteThing.image



# then, in your main loop, blit the sprite's .image attribute to your
display surface

mySpriteGroup.draw( screen )

pygame.display.update()

Re: [pygame] OpenGL stretch of a pygame.Surface

[Noel Garwick]

Right now you are blitting tiles to a 640x480 surface, and then performing
a transform on the whole surface and then blitting it to the display?

If this is the case, then try to only perform the scale operation when the
resolution is changed (instead of once each frame) and see how that works.
 I know you mentioned that the full screen blit operation seems to be the
main bottleneck, but this should help too.

Re: [pygame] Re: Pygame not handling keyboard tracking correctly

[Noel Garwick]

Im curious why "is" is bad in this case, as well. It's a constant; isn't
that a good use for is, whether it's referring to an int or not? I tend to
do this for event handling.  Maybe ints are always pointers in python?

The caveat for events is just warning you that the queue could fill up if
you didnt call pygame.event.get() at all.

Re: [pygame] Lightning Talk Timer

[Noel Garwick]

Hi Diliup,

I believe that there is a slight gain in performance when using set_allowed
so that only certain events are added to the queue.  I have never profiled
it, but I doubt that it's terribly more efficient. I would just do the
usual method of polling for events each loop, tracking the held keys, and
handling them appropriately, and see if that meets your requirements.  For
your case, you may not really have to track held keys, and could just run a
function to turn tones on if a key pressed, and off when it is released:

while True:

tslf = fpsClock.tick( FPS )

for event in pygame.events.get():
if event.type == KEYDOWN:
if event.key == K_q:
play_tone( q )
elif event.key == K_2:
play_tone( 2 )
.
elif event.type == KEYUP:
if event.key == K_q:
stop_tone( q )
elif event.key == K_2:
stop_tone( 2 )

# draw and update buttons here...

pygame.display.update()

Thank you,
Noel

Re: [pygame] Alternate to graphics modules

[Noel Garwick]

True.  Still, some might see a distinction between the compiler taking code
that a human has made, breaking it down and optimizing the calls into
operations, and then assembling that vs. using python to make calls to
functions written in python that call functions that someone else has
written in C.

Of course, all of this is just academic (vaguely :p).  The cool thing about
this thread is that Elias' request was not met with "use C, n00b", ">
suggesting python should be used for low level ops..", or even just
silence.  Instead, pygame-users explained the logical issues with the
request (that the OP likely wasn't aware of), and explained why the request
becomes more of a question of semantics than anything else. As well, they
offered suggestions for what could qualify as the next closest method to
fulfill that request.  That is cool.

But yeah:  If you want to use python's syntax to work with low-level
graphics calls, the modules with low-level bindings can offer a pretty
direct 'middle man.'  If you want to write C to use the libraries those
wrap directly, that's a possibility (and not as hard as it looks at first.)
 Or if you really want to get into it (mostly just useful for education,
but we wouldn't be here if pedagogy wasn't of some interest), try out some
assembly.  You will need to emulate an older set of hardware, since as far
as I'm aware things like 0x13h mode don't exist anymore, and as far as I
know most APIs to directly access a graphics card are going to be in C (if
I'm mistaken here, someone please correct me.)

If your overall goal is to get a better understanding of how graphics and
programming in general work, doing a small project in each of these
languages in order could be pretty enlightening (this is how it 'clicked'
for me, at least) -- tutorial links included:

1. Pygame ["Okay, so I take input, then I update the values from that
input, and then I draw.. I guess that's easy enough?]
http://inventwithpython.com/

2. 6502 Assembly (NES) [Registers, memory management, reading/writing to
ports/specific addresses, what loops, containers, and other things we take
for granted actually look like, etc.]
http://www.nintendoage.com/pub/faq/NA/nerdy_nights_out.html

3. C [Working directly with C and SDL or OpenGL calls]
http://www.lazyfoo.net/SDL_tutorials/ (SDL)  && 

4. C/Pygame ["Now that I understand how all that boilerplate works, I can
feel comfortable using 'shortcuts', since I see the benefits they really
offer (so now the only benefit of rolling my own is going to be '..just
'cause' 95% of the time), and can foresee/avoid the things that could cause
bottlenecks. Or I can use C since I want to experiment with designing more
complex 3d shaders, physics, etc. Or just because I think it's fun to use
C."]

Re: [pygame] Pygame for Android question: videos possible?

[Noel Garwick]

I think that devs are waiting for the next version of SDL before they
implement it.  You could always do it manually; blit a series of images to
a surface, while playing the soundtrack using pygame's mixer module.  I did
this (using ffmpeg to extract still frames / audio track, along with a
script to try and remove redundant frames to reduce file size) to get some
renpy games working on android and it worked pretty well.

Re: [pygame] Re: HELP PLEASE: sprite collision - object not iterable error

[Noel Garwick]

Hey I'm on my phone so I can't see the example you need help on  
specially, but here is some general help on the subject:

Arguments are the variables passed to a function.

Example:

def getDogYears(name, age, canine=False):
if not canine:
age *= 7 # age times 7
return "%s is %s years old in dog years." % (name, age)

>> samsDogAge = getDogYears('Sam', 5)
>> print samsDogAge
>> "Sam is 35 years old in dog years."

In this case, the arguments for the function getDogYears() are:
-name
-age
-canine (optional)

So the "second argument" would be the subject's age. Also note that by  
using "canine=False", we have set an optional argument. This means  
that, if no 3rd argument is given, the function will automatically set  
the variable to it's assigned default value. (In this case, 'False')


Hope that helps! :)

Re: [pygame] pygame performance limits

Ren'py actually requires more memory than you would think.* The ease

Renpy :p

Hi, Armor Nick.

Some common bottlenecks I've encountered:

rendering many images per frame
brute force collision checking
computationally intensive logic and AI
real-time image transformation
heavy usage of images with SRCALPHA
2D and 2.5D layering
particles

These are easy limits to hit early on especially in scrollers,  
platformers, and bullet hell type games, or when you start adding  
environment and GFX.


But there are clever techniques that pygamers have developed to deal  
with them in the form of cookbook recipes, libraries, and modules.  
Many issues can be easily mitigated by selecting a culling technique  
or two to reduce the number of things processed each game loop.


Some people popping into IRC lately seem easily frustrated by these  
challenges, wanting an inefficient workload to just perform well. I  
can understand the sentiment. But I personally get an immense amount  
of pleasure from conquering these challenges. :)


When I started pygame three years ago I was told you can't do a  
scrolling action-RPG: it's too much work for the CPU. Since then,  
computers became a significantly faster and several people have  
produced reasonably impressive action-RPGs, as well as other genre.


For some examples one only has to look among the top places at pyweek.org 
, where pygame competes with the likes of pyglet, cocos2d, and  
rabbyt, all of which have the proclaimed advantage of 3D  
acceleration. It's become clear to me that for most hobby games the  
only real limitation is the resourcefulness of the programmer.


I personally haven't yet hit a wall with Python or pygame that  
forced me to look at another framework or a natively compiled  
language, and I've done a few relatively ambitious projects.


That may seem like a biased representation of Python's and pygame's  
capabilities, but I assure you it's not. A few times a year my eyes  
wander to other game development libraries or engines, but I keep  
coming right back to pygame.


Hope that perspective helps.

You should be able to just use any image with the same dimensions as the one

With Apple announcing a new Mac App Store, and MS

announcing a new Games

Will py2app need changes, so I can insert Apple

Certificates into the
app?



Will py2exe need updates to survive the Windows 7

compatibility test?


Inquiring mind wants to know...

Re: [pygame] Ghosting

battery, another to maximize performance, etc.,  One of the ways it does
this is by adjusting the min/max CPU usage.  You may want to try messing
around with that in your Power Settings.
