Problem N°1: I have no sound when driving on textures
Problem N°2: Slowdown texture is not working so well shorcuts are possible

Hi,

this track does not use the latest track exporter. Are you using STK 0.7 alpha 3? Many fixes occurred so it may be a good idea to update to latest SVN

In any case,

{l Code}: {l Select All Code}

<material filename="snowtrack-phoques.png" >


needs to be

{l Code}: {l Select All Code}

<material name="snowtrack-phoques.png" >


I found this in shell :

{l Code}: {l Select All Code}

I know Texture's bug
I will searching for, but it's not urgent

My material .xml :

You have to use 'filename' in the sfx entries, not 'name'. You _can_ then give them a (short) 'name', in case that you want to use the same sfx for other textures (this way there is only one change if you want to change a sfx). E.g. you would set filename="glace.ogg" name="glace" - then you can use glace in all other textures as sfx.

So, is there a problem with wooden_bridge.ogg from the material.xml of snowtuxpeak track ?


1 <?xml version="1.0"?>

3 <materials>
4 <material name="ice.png" reset="Y"/>

11 </material>
12 </materials>

How can I increase slowdown effect, please ?

Rudy, s'il vous plaît de comparer les deux noeuds XML en vorte document. La première est correcte, la seconde est faux.

Not that I am aware of - unless I am missing something?

7 <sfx filename="wooden_bridge.ogg" name="wood" rolloff="0.6" min-speed="9.0" max-speed="22.0" min-pitch="1.0" max-pitch="1.7" positional="yes" volume="1.0"/>

11 </material>

The first time we use 'filename' to specify the name of the ogg file, and define a 'name' ("wood"). In the 2nd material we only need the short 'name', and stk will know which .ogg file to use (from the filename attribute of the first material file).

Cheers,
Joerg

This is a bug in Material.xml of snowtuxpeak

rudy85 {l Wrote}:How can I increase slowdown effect, please ?

Same question, again, Please

<material name="Slowdown.png" slowdown="0.01"/>

This maximum is not enough

<material name="Slowdown.png" slowdown="0.01"/>

Contary to it's name, "slowdown" does not slow you down. In stead, setting a low value for "slowdown" it will all but kill your engine power. (I think "engine-power" is a better name for this variable).

I think it's better you lower max-speed instead...

asciimonster {l Wrote}:I think it's better you lower max-speed instead...

And how

in stk_config.xml, value
<engine power="400 450 500" max-speed="15 20 23" brake-factor="11.0"
max-speed-reverse-ratio="0.3"/>
but I can be wrong

I cant change it to my track without changing values for all ones

I would be wise NOT to change the stk_config.xml since it controls the behaviour of the entire supertuxkart game.

Rudy, it should not be more than

{l Code}: {l Select All Code}

<materials>
   (...)
   <material (...) max-speed="0.3"/>
   (...)
</materials>

For more information, see Materials_xml.

asciimonster {l Wrote}:For more information, see Materials_xml.

But I think I have to update that page, the details about speed limits are outdated. For now have a look at some example slowdown settings in existing materials.xml files, I hope to fix this by tomorrow.

Cheers,
Joerg

I finally found , SFX must have a name and a filename

{l Code}: {l Select All Code}

<?xml version="1.0"?>
<materials>
  <material name="ice_dark_transp" alpha="Y" light="N" collide="Y"/>
  <material name="Ice-transp.png" alpha="Y" light="N" collide="Y" anisotropic="Y"/>
  <material name="fondu1.png" alpha="Y" light="N" collide="Y"/>
  <material name="snow2.png" ignore="Y" />
  <material name="Slowdown.png" slowdown="[b]0.1[/b]" max-speed="[b]0.1[/b]"/>
  <material name="snowtrack-crystal.png" >
     <sfx  name="crystal" filename="crystal.ogg" min-speed="1" max-speed="1" rolloff="0.1"  volume="2.0"  positional="N"/>
  </material>
  <material name="snowtrack-phoques.png" >
      <sfx  name="phoques" filename="phoques.ogg" min-speed="1" max-speed="1" rolloff="0.1" volume="1.0"  positional="N"/>
  </material>
</materials>

A question, again, can values be under 0.1 unit (eg: 0.05) ?

I believe you can enter any floating-point value

Hi,

I've updated the wiki page about materials, the documentation of slowdown-time and max-speed should now be corret:
Materials_xml.

Cheers,
Joerg

ok, thanks
