[pygame] kind of animation

[DR0ID <dr0id@xxxxxxxxxx>]

Hello everybody

I want to implement some animation and came up with 3 different ways to 
do that:

1. frame based animation

2. time based animation

3. event based animation

Well 1. one is clear: on each frame the animation is advanced one image. 
Simple to implement, but on different machines it runs with different 
speeds ( although you slow it down to a fix framerate).

The 2. one is a bit different: on each frame the time is passed and the 
animation is only davanced if the time for an image has passed by. On 
different computers it should run equaly fast, not depending on the 
framerate (because it depends on time).

And the 3. one only advances the animation if an event is received. Ok, 
doesent look practical but in combination with a timer perhaps it could. 
Or if one wants to make the animation depending on user action.


I wonder in wich way you do your animations. As said, I think framebased 
is the simplest thing to do, but perhaps not the best. And perhaps there 
are other ways to do animation!? There is also the other question: how 
to store the images for the animation. A list of images? Or one big 
image strip and then only changing the source rect? Or a list of 
sprites? What if an object uses 4 different animations? Use 4 lists in a 
dict? Or a list of animation-objects? Or an 2D-image strip and move the 
source rect?

You see I have some questions. :-)
