Changes:

• Fixed texture loading bug when loading non png texture fails.
• Starting gate angles are now range reduced.
• Custom sounds per bike/skin.
• pipe2/pipe4 commands have been renamed to just "pipe".
• pipe command has two new parameters which give the first and last delay lines to affect. There are 16 delay lines to adjust.

The naming for the pipe info file goes like this. If the bike skin is called "yz125-2010 Stock-Blue.png", it will try the following files in order:

yz125-2010 Stock-Blue.pipeinfo
yz125-2010 Stock.pipeinfo
yz125.pipeinfo
default125.pipeinfo

The pipeinfo file should look like this:

Code: Select all

pipe 1.75 0.1 0.4 0 0
pipe 2.5 0.3 -0.4 1 15

The first line sets delay line 0 to simulate a 1.75 foot pipe at .4 amplitude.
The second line sets lines 1-15 to simulate a 2.5 foot pipe at -.4 amplitude with the lines covering .3 feet.

Replace mx.exe or mxbin with one of the above files. I'd keep a backup of the originals since these aren't well tested.

Thanks josh.

Josh, what do these delay lines stand for? Time? Distance? Rpm?

[jlv]

Each one echoes the signal back after a delay with the given amplitude. The pipe command divides the length by the speed of sound to get the delay. When you set more than one line at a time, it spreads them out over the distance given by the silencer length which gives you a poor man's low pass filter.

i dont get it

[Duckstream]

so i make me values in notepad (forexample) and save it as a .pipeinfo file?

[Kawasakis]

Awesomeness. Thanks Josh for these great snapshot's.

Nice day today ! great job Josh !

Now you made sound by bike/skin, what about some other bike settings ?
Making a save/load menu for bike configuration and maybe an auto-loading defaut settings feature by bike and by track is doable ? If not, as minimum, we should be abble to quick load a bike config within the 30 sec before the start. (Choosing a defaut skin by bike is secondary but could be nice too and harder to do (before restart for loading textures).
Since i ask this feature I hope you plan to work on that soon, because every other serious sims allow to load and save vehicule settings. If you did some work about this king of feature please tell us what your plan.

good job jlv

Just to say I saw a difference in texture usage between windows seven x64 and XP 32. I had bad settings in texture size (512X512) but i have only 512 M or video ram. And didn't saw this error because I play generaly with seven, curiously nice frame rate, and I force the anisotropic filtering x16 with graphic driver to (greatly) improve texture quality. But with XP, my framerate is very low and it's the normal way (also, textures are finer without anysotropic filtering forced). There's a mistake somewhere, i use same driver config for both.

[i_Bite#21]

does this snapshot include every snapshot that youve made? and i cant get it to work in game, i extracted the files but it wont extract them what do i do?

[giopanda]

sorry josh but i really can't understan how the new pipeinfo fils work..
whare are exactly those numebers?
and how they change the final sound?
i'm trying to make something but i'm really going random..

[yzmxer608]

pipe 1.75 0.1 0.4 0 0
pipe 2.5 0.3 -0.4 1 15

Blue sets the delay lines 0-0 (so it's only 0).
Red sets the delay lines 1-15 (so that info is used for all of them).
Green is the same as before for making the pipe sounds.

The delay is a echo that plays after a certain amount of time depending on the rest of the pipe info. So, pipe length/speed of sound=delay.

Pretty much just restated what Josh said but it might be helpful to some. Still trying to figure out the last thing he said:

When you set more than one line at a time, it spreads them out over the distance given by the silencer length which gives you a poor man's low pass filter.

What do you mean by "them", the delays?

Yes. If you set five lines like this:

pipe 2.5 0.5 -0.5 0 4

It will be similar to this:

pipe 2.0 0.0 -0.1 0 0
pipe 2.125 0.0 -0.1 1 1
pipe 2.25 0.0 -0.1 2 2
pipe 2.375 0.0 -0.1 3 3
pipe 2.5 0.0 -0.1 4 4

[giopanda]

Yes. If you set five lines like this:

pipe 2.5 0.5 -0.5 0 4

It will be similar to this:

pipe 2.0 0.0 -0.1 0 0
pipe 2.125 0.0 -0.1 1 1
pipe 2.25 0.0 -0.1 2 2
pipe 2.375 0.0 -0.1 3 3
pipe 2.5 0.0 -0.1 4 4

so let's say i want to replicate the stock silencer, that has a muffled sound throughout almost the entire rpm range and then change to the braaap sound around let's say 12/13000 rpm, what should i do?
sorry but those math/physics/engineering stuff is too complicated for me but i'd like to understand how this works..
