[Super-tux-devel] SuperTux 0.0.6 released

[Tobias <tob...@gm...>]

Hi all,

SuperTux 0.0.6 just was released!
https://sourceforge.net/project/showfiles.php?group_id=69183

It would be great, if someone could write a good announcement for it
and send it to as many news sites as possible. :)

We can concentrate on new features again. I'll write a 0.0.7 TODO list,
on which you can comment tomorrow.
But now go and download 0.0.6 have fun and build a few levels so that
we can even release a 0.0.6.1. ;)

It would also be great, if you could build binary packages for your
favourite distribution. ;)

[Super-tux-devel] Laptop fixes [patch]

[Ricardo C. <ri...@ae...>]

Hi,

 This just fixes two small issues. They are not noticed in the current cvs, 
since the laptop doesn't even get flat.

 Tobias, commit my previous patch too and don't forget to remove line 98 
firstly.

If you wanted to do blurring and blending, the way I would do it would
be to provide a small matrix at each pixel giving the contribution of
the surrounding pixels.  This more general approach would subsume
blurring and blending, would be as efficient as blurring, and would
allow even fancier effects like small refraction distortions, which
could be useful for all kinds of effects. Of course, the whole thing is
super-overkill anyway, and I think the performance penalty would be too
high, but it's fun to think about it anyway :)

That's what I was suggesting. ;^)  Yes.

Of course, I went a step further and suggested BLURRING, as well as
blending, but I think that's overkill...

   Hi there,

   The "configure" script is there again. Now it uses AM_PATH_SDL as 
recommended by grumbel, (thanks for this hint:) ) I commited it so that ppl 
can help and report bugs. Some "enable-stuff" were introduced to improve 
developers' life :) Please type "configure --help" for more details. The .o 
and supertux will be compiled directly into the "src" directory. Do not try 
"install" because the data files are not handled yet :)
   
   By the way, I have some serious real life issues currently. That's why I

 Yes, in laptops, for instance, the player seems to continue colliding with=
=20
them after the first collision.
 This happens because the loop is so fast that the player doesn't have the=
=20
time to jump and be away from the enemies' square. Solution is to (when the=
re=20
is a collision) make sure the collider's position is changed in order to be=
=20
away from the collided, and apply the jump, as we do now.

 OpenGL can be used by passing the --opengl / -gl argument.
 The decision was that, in the (far) future, if there are some things that=
=20
need to be done and cannot be implemented in SDL (for performance reasons)=
=20
and that affect the gameplay, SDL will be dropped, in favor of OpenGL.

 SuperTux supports Alpha blending, so couldn't that be made by setting up s=

pixels, in the stalactite image, to a value from 0-255 ?

(a part; stalactite normal image, can be animated!)

I'd say the laptop should be destroyed after the first enemy is kicked.

You mean collisions between game objects, right? Yeah, that's true!
For game-object with map collisions I'd say there is only one known bug,
which occurs in a very special situation with low frames, so we can
nearly say it was perfect.

[Super-tux-devel] Bad guys fixes [patch]

[Ricardo C. <ri...@ae...>]

Hey there,

 This patch fixes a few issues (not all!) from bad guys, give it a try. (the 
patch is small, but gave some work, so appreciate it! ;) )

 The following bugs should be fixed:
- When Tux is big and is stopped, laptop does not harm him. This is a result 
of the fact that now collisions are not tested upon the velocity, but 
player's position and size;
- When laptop is being hold, you are invincible. This is a gameplay issue, 
laptop could be destroyed/kicked after the first enemy killed or/and player 
could only hold the laptop for a few time.

 Collision system should be studied a little more, since there seem to be a 
few issues, regarding it.

 There was this bug:
if(pbad->dir = LEFT)
 (line 174 badguys.c)
 Shouldn't gcc said anything? We are using -Wall... At least, g++ would have 
warn about that.

 Tobias, I sent a few time ago, a patch for making the powerups going in the 
opposite direction of the side that the player collided with the brick... It 
looks like that isn't being done, wanna me to patch that again?


 Anyway, I had a look at SuperTux 0.0.5 code and i must say that it has 
evolved a lot. I mean *a lot*! So, I guess, SuperTux future can only be 
brilliant, after all ;)

Bests,

I never tested the color things, so it's good that you found the bug

Your level is very nice! I think it can be included in 0.0.6, but it

Hey there,

 The patch just removes the  Y < 0 check, so that Tux can go into the upper 
part of the screen, even if it doesn't scroll (this was already requested and 
happens in SM1).

 I also include a level I've made that takes place in the sky. It has two 
problems though; first of all, it ends in the middle (?) and I was unable to 
use background colors, instead of the image (gives a black color, instead of 
the wanted colors).

I can either insert the level in DATA_PREFIX/data/levels/default as

works for me and SHOULD work for you, too.
