I wanted to add a basic tutorial how to build a track for GPL. But mostly for dummies like myself.

I went over to this site and followed it https://www.grandprix...ds.co.nf/GPLEA/ (click on the left under TUTORIALS).

Now I have doen the faboulus oval and may have understand what I did until the original tutorial reaches Part 5 Adding Objects.

Now I'm stunned. OK, it tells that they are speeding but some steps first helping me to understand what I do

Part 4: Adding Textures

I took a close look with Winmip and checked the mips. I have attached a screenshot of the found mip files to the needed from the mytrack.tex file.

0 0 0 10.0 10.0 error
1 0 0 10.0 10.0 asphalt
4 0 0 10.0 10.0 grass
6 0 0 10.0 10.0 gravel
2055 0 0 10.0 10.0 hay
2055 0 1 10.0 10.0 hay
2055 0 2 10.0 10.0 hay
2055 0 4 1.0 1.0 hay
2055 0 5 1.0 1.0 hay
2056 0 1 10.0 10.0 trees
2056 1 1 10.0 10.0 barrier

Syntax is clear but the different MIP file types not (Type, Mapp, Sub-Im). If some nice soul could help me here.

Then we proceed fast to part 5 adding side objects.

This section must be changed to the trk23doz format and there need to be added a HSV file. My question to make life simpler would be to proceed without adding side objects at this stage as it looks like as soon as I have a 3DO I can add things with different programs to the track.

What I have so far:

mytrack.gtk (with 7 sections)
mytrack.tex (assigning textures to walls)

Maybe I have

I have no pitlane (need to figure out how to add this)

What is needed now to create a running track ?

Help is appreciated

Hallo Bernd,

Here I have learned something.
(hier habe ich etwas gelernt.)

https://srmz.racesimcentral.net/inde...ansparent area
Have a look at toomis post.

https://gplr.bcsims.c...p?showtopic=247
Have a look a Ginettos post.

Perhaps it helps.

Now that was help indeed

Thanks Nigel and Yogi !

I will try to explain some basic MIP stuff first

[Bernd Nowak]

OK,
here's how I have read the MIPs for the tutorial and again some questions:

Quote

For the mips used in this example:

ASPHALT.MIP:

Its' a type 0 MIP which has Palette, Opaque, R8, G8, B8, A8 . NB the 8 alpha bits are unused.
There are no subimages
The bitmap is 256*256
Mapping is 3 which means it will be stretched vertical and horizontal (which seems very unusual. Mostly it's mapping 0 which means it will be repeated vertical and horizontal)

GRAVEL.MIP

Again it's a type 0 MIP which has Palette, Opaque, R8, G8, B8, A8 . NB the 8 alpha bits are unused.
There are 4 sub images which have sizes 128*128 (first) and the 4 sub-images 64*64, 32*32,16*16,8*8
Mapping is 0 which means it will be repeated vertical and horizontal

HAY.MIP

Its' a type 0 MIP which has Palette, Opaque, R8, G8, B8, A8 . NB the 8 alpha bits are unused.
There are 4 sub images which have sizes 128*64 (first) and the 4 sub-images 64*32, 32*16,16*8,8*4
Mapping is 0 which means it will be repeated vertical and horizontal

TREES.MIP

It's a type 1 MIP which has Palette, Transparent, R8, G8, B8, A8. NB the only values used in alpha should by 255 (opaque) and 0 (transparent)
There are 5 sub images which have sizes 256*128 (first) and the 5 subimages 128*64,64*32,32*16,16*8,8*4
Mapping is 2 which means it will be repeated horizontal and stretched vertical

BARRIER.MIP

It's a type 1 MIP which has Palette, Transparent, R8, G8, B8, A8. NB the only values used in alpha should by 255 (opaque) and 0 (transparent)
There is 1 sub image which have sizes 256*32 (first) and the 1 subimage 128*16

As you can see the asphalt.mip has mapping 3 which I have checked with asphalt.mip from GPLPS installer and they all have mapping 0 and different sub images.

That leads to my second question why there are with only 5 mips so much different sub images ?

And for Nigel, I used RaceCon and RaceCon shows Repeat Horizontaly = yes, Repeat Vertically = yes for MIP mapping 3. Or is PapyBMP the tool to be used instead of RaceCon ?

Still I need to check how to create the track and what I need else
I have the GTK and the MIPS. It seems easy to create the MIPS but certainly needs some page on the Wiki telling a bit about MIPS and how to work with them

[Bernd Nowak]

I should attach the MIPS

OK. After some crazy stuff (C++ Expection error in trk23doz.exe) and a lot of edits it finally compiled. But some hazzle to get able to drive it

The obvious thing was to edit 67season.ini file. Done.
But a lot more had been missing !

To drive around my great oval I found that the mytrack.3do needed a grass.mip. Ok I know that it was defined in the mytrack.tex file. I borrowed me some from another track. Would have been nice if trk23doz.exe would mention it

Next I read that I needed a horiz.3do which I borrowed again including the various horizXX.mips. No good.
Using sciss.exe I noticed I need a sky.mib and a ground.mip. Same procedure, once again borrowed from another track.

Same for track.ini as well as page0.pbf, page1.pbf and page2.pbf.

Now to edit the page0.pbf seems easy.

A pitlane is missing. How to add this ?

I need to correct the pitlane stalls (It's raining cars )

I need to fix the borrowed horiz.3do to have a horizon which is adjusted to my small oval and need some tips how to do this.

For the TV1, TV2 and Pitlane Cam I used TrkCAMEditSetup.exe which seems to work.

And if I have all that I need to add some side objects as well as some AI.

I'm open for all tips and at least I can say that I have created a track for GPL As soon as I have finished the missing bits I will try to write a tutorial, based on the great GPL track creating guide. Interesting stuff for sure

Look at the helpfile in AiEdit it has a lot of the track.ini parameters explained.
There are also some problems described as well as some points to consider while making Ai.  


Btw, if you are on the point of creating ai be sure to test the pitlane exits of the cars in all modes.
I've seen some pitstalls were the cars could get on track in novice but not in expert mode.
I believe this has to do with the amount of space between the pitstalls. If you set it to short the longer cars won't get out of the pits.

[Bernd Nowak]

The AI is the smallest problem at the moment because I must first create the pitlane and second find a way to place trackside objects as well as a lot of other stuff

But thanks a lot for looking at the AiEdit help file. Sure will do

Thanks Swen !

Interesting Excel sheet. Do some guys know or have the Track Calculator excel sheet ? And is there an another method of getting the excel data into GPL TRK ?

I think I have managed to put in a part for the pitlane.

Just a question:

[ pit_lane_0 ]
lane_on_right = 1                       ; 0 if lane on left, 1 if on right
lane_has_wall = 1                       ; 0 if no pit wall, 1 if pit wall exists
lane_bounds_dlong = 4613.9 639.0        ; start/end dlong of the pit lane
lane_bounds_dlat = -18.1 -6.3           ; start/end dlat of the pit lane
pit_board = 11.0 140.0 -100.0 100.0     ; dlat of board, dlong of board, dlong LOS start, dlong LOS end (last 2 not used)

what is the measurement of the lane_bounds_dlong/dlat/board ? Is it decimal units ? Is it measurd from 0,0,0 of the track and where is 0,0,0 ?

Similiar question for this section:

[ pit_lane_0 ]
stall_0 = 255.00 -16.20
stall_1 = 241.74 -16.20
stall_2 = 228.47 -16.20
stall_3 = 215.21 -16.20
stall_4 = 201.95 -16.20
stall_5 = 188.68 -16.20
stall_6 = 175.42 -16.20
stall_7 = 162.16 -16.20
stall_8 = 148.89 -16.20
stall_9 = 135.63 -16.20
stall_10 = 122.37 -16.20
stall_11 = 109.11 -16.20
stall_12 = 95.84 -16.20
stall_13 = 82.58 -16.20
stall_14 = 69.32 -16.20
stall_15 = 56.05 -16.20
stall_16 = 42.79 -16.20
stall_17 = 29.53 -16.20
stall_18 = 16.26 -16.20
stall_19 = 3.00 -16.20

From testing I believe that -16,20 points to the right side from centerline with a distance of 16.2 (decimal units/meters/feet ???)

But from where is the 1st parameter been measured ?

How do you add flagmans and brake markers ?

How to work with the horizon ?
