[Super-tux-devel] A chat with Bill Kendrick

[sik0fewl <xxd...@ho...>]

Hi,

Bill came into #supertux today/tonight and pointed out some things that 
needed to be fixed. I've summarized them here.

-----

Grass in front of tux looks wrong
    - Snow Level 1

Ice blocks shouldn't walk through eachother

Stalactite hangs to low

Jumping through two blocks is almost impossible (so is falling through them)

Eggs come out of opposite side.. should always be right.

Iceblocks shouldn't die after hitting a single enemy

Tux should jump higher if you are running

Lives don't reset after Game Over

Tux should run faster when Ctrl is DOWN

"Tux looks too stiff when jumping"

The egg should be able to be changed directions when bouncing the block 
underneath it.

When Tux jumps in front of a pipe he shouldn't hit the lip of the pipe 
(anti-physics)
    - seemed okay for me, though

* make ST easier
[04:15:59] <kendrick> probably just increase accelerations
[04:16:10] <kendrick> make him jump quicker, but for less frames
[04:16:23] <kendrick> make his turn-around speed faster

[04:18:51] <kendrick> whenever i hit [Esc] when looking in contrib levels, 
it quits! :)

Find a better decel rate for sliding on ice

[04:27:51] <kendrick> btw; when you push into a wall (e.g., hit arrow right, 
but you can't move cuz of the wall), and then let go of [right] and jump, 
you shouldn't have any forward momentum!

 This kind of bug and wanted features submitting is a very healthing thing =
and=20
I appreciate it. Here goes, a few comments.

 Tilesets behaviour can be changed through the *.stgt file. Though, I am no=

familiar with that, could you fix that, Ingo?

 That behaviour was lost after cleanups and fixes in the collisions code. I=

have a look at that.

 That's a known bug, related with the fact that timing is no longer fixed.

 Tux jumping is a bit broken, I'll look forward for a fix.

 It just follows SuperMario 3 behaviour. Eggs go for the opposite side wher=

you collided with the box.
 This was introduced a while ago (0.0.6 features this behaviour) and I vote=

keep it.

 I think we should talk more about gameplay behaviours... Maybe in a future=

meeting.

 True. Jumping code should be reviewed.

 Known bug... A patch, anyone? :)

 Doesn't that happens?
 Well, the animation speed is too fast (timing issue), but besides that, it=

works fine.

 Ooops, looks like that was removed during a cleanup...

 Seems okay to me too.

 Not only in the Contribs, but in the Options or any other dialog. It shoul=
d=20
use the back button...
 I already sent a patch for that... It was never applied, I still have it, =
and=20
will apply it.

This was a simple foreground/background problem in the level file. I 
already fixed that.

Hmmm... the problem is, I designed the levels for the current jumping 
height. If Tux can jump higher, I'll have to redesign a lot of maps... :(

IMHO, Tux should be sliding less. The way it currently is, the sliding 
makes a lot of jumps extremely frustrating.


Btw, I am currently reviewing and polishing the maps for release. I 
finished 10 of the total 24 levels so far and I will soon send them to 
Ricardo to commit.

The normal jump should be 4 tiles high, while the accelerated should
be 5 tiles high. Currently both are something like 4.5 tiles high, so
level changes should be minimal.

Jepp, currently Tux slides to much, there are also a lot of situations
where you just run into enemies, without having much a chance to dodge
or break, unless you already know where the enemies appear (ie.
already run into them). Slowing down some enemies and giving better
breaking abilities should help.

Thanks.  :)  I'll add clarification below most of them, just to make sure
we're clear on what I mean. ;^)


<snip>
> 
> Ice blocks shouldn't walk through eachother

No enemies should walk next to each other.  For example, say you have
this:

  [Wall]  <1] <2] <3]

e.g., enemies 1, 2 and 3 walking to the left, and there's a wall in
front of them (straight ahead of #1).  When #1 hits the wall, it will
be like this:

  [Wall][1> <2] <3]

#1 turns around.  But then he'll hit #2!

  [Wall] <1][2> <3]

#1 turns around again, and #2 turns around.  But the #1 will hit the
wall again, and #2 will hit #3:

  [Wall][1>  <2][3>

So you see, #1 gets bumped around like a pinball for a while. ;^)
#2 less so.  #3 just hits once and goes on his/her way:

  [Wall] <1][2>  [3>

Once last bump into the wall...

  [Wall][1>  [2>  [3>


And they're on their way again, in the opposite direction
(but the SAME order!)

  [Wall] [1>  [2>  [3>



<snip>
> Jumping through two blocks is almost impossible (so is falling through 
> them)

By two blocks I mean:

  +-+ ^ +-+
  |1| X |2|
  +-+ | +-+

X marks the spot :)  You can't fall through them either.  You should
be able to walk quickly across the tops of two that are arranged like
that...  So that if the level has this:

  # # # # # # # # # # # #    # # # #

You can run across it, and would only need to jump once, at the big
gap.  But, if you slowed down, you'll need to be careful, otherwise
you'll wall through!



> Eggs come out of opposite side.. should always be right.

I guess I need to play SMB3 more.  I really like it always coming out
the same direction, though.  This also allows for evil things like:


  ##?#########################


  #####   #    #    #   #    #  #####

e.g., hit the "?" block and you don't get to grab the egg until you've
traversed something difficult. >:^)



> Iceblocks shouldn't die after hitting a single enemy

Yes!  I can't believe someone changed this!!!

If you have an enemy setup like this:


   <1] <2] <3] <4] <5]

Where "1" is an iceblock and "2" thru "5" are, say, snowballs or other
iceblocks, if you stomp "1" and kick it to the right, it'll kill all
of the others!

   _1><2] <3] <4] <5][Wall]

      !2!
      _1><3] <4] <5] [Wall]

         !3!
         _1><4] <5]  [Wall]

            !4!
            _1><5]   [Wall]

               !5!
               _1>   [Wall]

And then he's still alive, and will bounce back if he hits a wall! >:^)

                  <1_[Wall]


> Tux should jump higher if you are running

Yes!!!


<snip>
> Tux should run faster when Ctrl is DOWN

By this, I mean...  "Yes, I guess he DOES go faster when Ctrl is down...
but it's really hard to tell.  It doesn't seem MUCH faster!"



> "Tux looks too stiff when jumping"

My wife described as:  "You know when they have enemies that stick to
your head and make it hard to move?  That's what it reminds me of."

What >I< assume she means is that Tux's face/chest/neck doesn't seem to
look much different when he's jumping.  It's like he's doing Riverdance. ;)

But honestly, that's her comment.  >I< think he looks adorable!
I can't wait to see a 'big' version of him running around!


> The egg should be able to be changed directions when bouncing the block 
> underneath it.

E.g., hit the "?" block:

     [?]
  [#]^^^[#][#][#]


Egg pops out:

      [0>
  [#][ ][#][#][#]

Hit another 'bounceable' brick (e.g., another "?", or a breakable brick,
either as big or small Tux):

          <0]
           [#]
  [#][ ][#]^^^[#]

And the egg goes the other direction...

       <0]
  [#][ ][#][#][#]

In other words, if you have this:


  =====
  |   |
  |   |
  | X |
##########

(X marks the Tux)

If you jump UP, you shouldn't bump your head on the "===" lip.

However, when you're falling DOWN, you should land on the lip.  e.g.,
so you can go from the state in the diagram above to this, just by
hitting the [Jump] key:

    X
  =====
  |   |
  |   |
  |   |
##########

(Again, X marks the Tux ;^) )

<snip>

Admittedly, I only get 26fps.  But that should be PLENTY for Tux to move
around quickly, since the game is no longer dependent on the FPS it gets! :^)


Thanks much!  I'm so glad I can finally compile it now!
(Had to upgrade to automake ~1.9 and install g++-3.0 ;^) )
