I'm glad I asked you guys ;) I've downloaded the Python version of NeHe 1-10, and I'll take a look at it soon. One of the reasons I wanted to get into OpenGL, although I probably won't be learning it until A LOT later, is things like particle effects and other types of visual effects (I know a lot of people who used Direct3D in their 2D games to do such things), and plus I had assumed that OpenGL draws more things much quicker if you have Direct Rendering and code it properly. Plus, I'm learning 3D modeling and, although 3D graphics for games don't seem as good as well polished 2D graphics to me, I'd like to at least experiment with the idea as soon as I stop sucking at Blender. Plus, if I ever want to make that Tetris Attack clone (in the far future) with the 3D mode, well, it has to be in 3D :P Also, kinda off-topic, I've found an idea for my first game that is so simple, that even I can't screw it up. ...I think. (Plus, the game is awesomely addictive) http://jayisgames.com/archives/2007/05/speed_cluster_2.php A simple game concept, yes? I think I could do it. I'm positive, in fact. I could practice all sorts of simple concepts, like randomization, 2D graphics, simple logic, and different types of input, like keyboard and mouse. Oh, and I can finally learn how to make a menu. I still have no clue how to do that (or make any other screens, scenes and popup menus in games).

[pygame] Starting a game
Alright. I don't know if I'm going to be using that MVC stuff... although I might reprogram the game to use it later, if I decide it'll be better... but I want to start a game now! I'm so bored just sitting here that I may as well start something. So now, I'm going to get started. But the problem is that the last time I tried it, I over-complicated it by using advanced sprite functions that I didn't understand at all. I'm still trying to figure out an eaiser way to draw stuff than making everything a class and making it extend from pygame.sprite.Sprite (painful .) Also, some concepts of object orientation seem to have bit me. How should I have classes interact with each other? I know I was doing it completely wrong last time, and one of my friends called me on it. But I forgot how he said I should do it... Well, I'm going to see if I can drum up something usable...

I'm still trying to figure out an eaiser way to draw stuff than making everything a class and making it extend from pygame.sprite.Sprite (painful .) My advice, come up with a game concept, then come up with one aspect of it that you can implement easily and do that first. For example, if you were making a tiled rouge-like game, you could come up with some simple art for a player character (like a knight or mage) then make it so you move the character in a grid on the screen. If you are making an asteroids type game, make it so you can turn your ship, then implement thrust, etc. Try to bite off little chunks you can do in a few hours time and don't try and invent the whole thing at once, learn as you go. Some kinds of games (such as the rouge-like one I mentioned) already have lots of pygame implementations, and there are frameworks that can help with things like tiling, level design, etc. Sometimes though it may be as hard to learn to use the framework as it is to learn pygame itself, so beware of biting off more than you can chew. Also, some concepts of object orientation seem to have bit me. How should I have classes interact with each other? I know I was doing it completely wrong last time, and one of my friends called me on it. But I forgot how he said I should do it... Look at other people's code. Games and OO programming go hand-and- hand IMO and it really helps you if you have the right level of abstraction. The sprite class is supposed to help you in this regard, giving you a small organizational unit for the components of your game. OTOH, using Sprite may make it more difficult to implement certain patterns (i.e., MVC). But to risk overusing a cliche: Don't let the perfect be the enemy of the good, figure out how to make something work first then learn how to make it better. Don't try to learn everything at once. Maybe you said this before, but what kind of game are you making? Is there another pygame that has similar ideas and elements you can borrow from? -Casey I'm trying to decide between a Tetris Attack clone (my friends were all interested in this idea), an RPG (some of my other friends recommended I start with this, but if I did I wouldn't allow myself to do something like Final Fantasy, it'd have to be something really weird like Tendrills) or an arcade shoot-em-up game like the one I tried to make for my senior project, which would be a series of boss-battles in which you have to type a set of words to damage the boss. My teacher really wanted to see what it looked like when it was done but my first try ened up... well, crappy to say the very least. (it couldn't shoot bullets T_T) I had other people on the ML say that I should start backwards from what I did last time: try to get an enemy firing bullets before I get the player on the screen. Which I probably will do, just to make sure I do it right this time. You say to look at other people's games for an example of abstraction. Do you have a particular one in mind?

MVC has strong advantages when you need to present and interact with the same data in multiple ways, but often in simple games data is only presented a single way. Using MVC has advantages for unit testing as well, but how many pygames actually employ unit tests in a meaningful way? For some low-level functions (e.g. vector math) unit tests were rather useful. Also, I couldn't have refactored the AI code that Ignas Mikalajūnas wrote for me without writing a set of unit tests for it. Other than that, my initial resolution to have everything covered by unit tests evaporated pretty rapidly when I got caught in the frenzy of prototyping the fun stuff. What's unit testing? I wouldn't be surprised if I knew what it was, but didn't know what it was called. I also wouldn't be surprised if I never had the slightest idea what it was, either. I'm curious how widespread these practices really are in the pygame community, not to make a point for or against them, but to better understand theory vs. practice. I'm curious about everything.

T_T My original email had an explanation of the technique but I thought that might be considered spoilers :). It might help you understand if you went into the code. At the very top, there's a line called FRAME_COUNT. Change it to 1 or 2 and see what happens. It's a cute trick, but it relies on certain properties of the sprite motion -- namely that all sprites are identical, and are all following the same trail, but are just on different places on it. I think generally the use of sprites in a game runs counter to these assumptions -- you introduce a sprite class because the sprites aren't identical, and they move differently. But like I said, maybe bullet hell games. Ethan Oh... that's still cool, though. Maybe after I fix my little game thing that currently is out of order, I could implement something like this? It would be cool to have, oh say, 2 or 3 of these running at the same time making a pattern. Would that make sense or would it be asking for trouble?
[pygame] loading images and sounds
So, I have a helpers.py file that I imported into all of my files. It loads sounds, images and music. However, when I load an image, I can't do anything with it because pygame keeps saying that tuple object has no attribute 'blit' and I can't do anything. I noticed at the bottom of this helper file, it says return image, image.get_rect() on it. What should I do with that then? Here is the file that is causing the problem and the helpers.py file. this is due on the 3RD OF MAY OH DANG IT GOT HERE FAST!!! :P (I said I wouldn't be rushing to get it out at the end of the deadline and, hey look, I'm rushing to get it out at the end of the deadline.

I use Linux and the user I've written the app for is on Windows. I recommended they slow down the pointer in the Windows crontrol panel. This works for Windows but the mouse runs at full speed in my app, then goes back down to the slower speed he's set in Windows once he exits the app. So is there any way to slow down the mouse in pygame? A couple people on the irc channel suggested slowing down my game engine, but I don't have much of an engine and that wouldn'ts affect the mouse pointer anyways. Any suggestions?

But when you double-click and pick run or right-click and pick open with python, the current working directory does NOT get set, and the game cannot find its data files. What I do for my own games is something similar to this: import os import sys os.chdir(os.path.dirname(sys.argv[0])) That makes sure that the data files will always be found where you expect them. --- James Paige That's good information.

That's not quite what I meant... I'm bad at describing things. Let's see... um... my drawing code uses the RenderUpdates method. At the top of the main loop, I have: all = pygame.sprite.RenderUpdates() after that, I have all the classes listed as: textsprite = Textsprite([]) the text I want shows up in the brackets. I'll be changing that later anyway. Next, I have all.add(textsprite) which makes the game update the sprites in the listed classes, in this case textsprite. A little later down, I have: all.clear(screen, background) all.update dirty = all.draw(screen) pygame.display.update(dirty) which would redraw all the sprites on the screen that have changed without updating the ones that haven't. My question is, what do I have to put in all.add to get the bullets to actually show up on screen?

If this is really all I have to do, how do I get the bullets to register with my screen redrawing class? I use that dirty rect update method where you have to specify the class with the sprite class. If you want the bullet objects to have a reference back to the object running the game (if any), you can give them that reference. Say: class Game: ... def MakeBullet(self): self.bullets.append(self, Bullet() ) class Bullet: def __init__(self,game_object): self.game_object = game_object If you do that, the bullets can then call functions of the game object. I do that for the ships in my game so they can say, Hey, I got destroyed, but not for bullets. Also I've got separate lists for player and enemy bullets to simplify collision detection.
Re: [pygame] Firing bullets
That's the most basic way of doing it... but reusing bullets means that the program doesn't have to delete and recreate bullets every operation. If I understand correctly, it only needs to make one set of bullets. I know that it is faster, but I'm not sure how much faster, or how much more efficiently it will work, and if it is easier or harder to code it that way, although the kill and recreate way sounds a bit easier to code. I don't know which I would be using, though...

I don't care about complex physics simulations like hinges, and am willing to callously treat objects as hard boxes standing upright, on or above a plane. I just want characters that can run and jump around in a game world and interact with stuff. As a result you can so far make a game world with an object in it that can move around, with the following code: import Nutshell w = Nutshell.BasicWorldsim() w.MakeEntity(nature=Object,name=Pretzel,velocity=[1.0,0.0,0.0]) w.SimulationStep() The collision detection isn't quite done yet, but motion is, it's optimized for efficiency, and I'm going to build on the basic worldsim class to get zones that can be loaded/saved. I'm willing to open-source this if anyone's interested, especially if people are willing to help with graphics/graphics code. My question is, does it seem reasonable to build a goodly chunk of the game character code into the simulation, ie. having RPG stats mixed in with the class that handles the physics of living creatures? Considering the module as a pure physics simulation, that seems odd, but since a physics simulation doesn't really need a Creature class at all, maybe it's justified. Kris

I do not know what danmaku is (actually thanks to google I think I now do), but I have had success at work and at home with intensive 3d applications written primarily in Python. If you feel you are able to develop this and are interested in doing so, you should try it. In my experience most complaints against Python tend to be based on poor design and/or implementation of algorithms rather than the language running dog slow. (And you can make the plunge into C extensions or whatever if it really becomes an issue.) Python having accuracy limitations seems very suspect as well. Where the heck did that assertion come from? -bob A tutorial on the pygame website says that you shouldn't try to get pixel perfect hitrect detection. Wouldn't that mess with the game's accuracy? That's a general rule of game programming; doing bounding rects or circles is a LOT faster than comparing swaths of pixels. It's possible to do it with pixels in pygame if you really want to, and I'm pretty sure I've seen extensions that do exactly that. You still need to design for bounding rect or distance based collision detection in *any* environment even if doing pixel based collision in order to decide which things are worth comparing. Bounding rect? you mean like something that surrounds an object and tells if the two bounding rects touched? That's what I thought he meant by pixel perfect detection. Oops. ^_^;; And the speed limitations thing comes from the fact that, well, I suck at coding. :P I read one tutorial that if you're making a fast paced game you shouldn't even bother with Python. Of course, I considered this BS, but I know that Python isn't as fast as C. That doesn't mean it's _slow_, though. If you can do fast paced games in Flash (and you can), then you can do it in pygame. I've seen an ikaruga clone in Flash, which sounds like the kind of game you're thinking of. That said, you need to know what you're doing in nearly any environment to get good performance when you're managing hundreds or thousands of things many times a second. Good point. Although it wouldn't be thousands of things. at the most a hundred or two. Didn't know you could use C extensions in Python. Is that like saying, if I have a library I like to use in C (in this case, Kenta Cho's awesome bulletml library) I can use it in python? How much hacking would that take? pygame is a C extension. I don't know anything about bulletml, but you might be able to use it relatively easily with something like ctypes or swig. Otherwise you'd have to write code in C or Pyrex against the Python API that gets what you want out of it. someone was writing a python wrapper for it and then disappeared off of the face of the planet _ I kinda don't have time for that, though. Other reasons I wanted to change the idea of my game is because... 1. Time limitations. It'd probably be easier to come up with a grid instead of 20 bullet patterns and program them all, but if I could use bulletml this wouldn't be nearly as much of a problem. 2. I never thought of doing it this way and someone else said it would be a good idea, and I agree with him now. 3. No need to change the game code for every keyboard layout. My typing danmaku game idea assumed everyone has a QWERTY keyboard. 4. I've never seen anyone else do this, while I've seen multiple shoot-em-up typing tutors (but none of them were danmaku and none of them were based on the Touhou games). 5. Well... uh... my typing danmaku game would make a good sequel. ;P I didn't mean to make it sound as if it's impossible to make a danmaku typing game in Python, but rather a newbie like myself would end up making code that is slow and inaccurate due to lack of information and (moreover) time. None of these really seem terribly relevant to Python or pygame. You'd have the same problems with just about anything... Yeah, I know, which is why I am going for something a little simpler. Since it sounds like you're just starting out I would recommend doing simpler games that you can actually finish instead of trying to make your first or second project a masterpiece... but again, that's not Python

Rest assured that Python has no trouble doing integer arithmetic accurately, and will tell you for certain whether the bounding rects intersect or not. :-) (If you were using floats for your rect coordinates, you might have some accuracy limitations, but that's a general feature of float arithmetic, and nothing to do with Python.)
