help implementing rivers [resolved]

[Kristian]

Dear all,
Trying to add rivers to Pak Contrast / Simutrans 102.0. I made an image file, and a dat file like this:

Obj=way
Name=river
cost=1000000
maintenance=1
topspeed=15
max_weight=1000
waytype=water
system_type=255
...

and the pak compiled without error.

I then added this to the simuconf.tab:

# rivers:
# The highest number is the smallest. A river with max_speed==0 is not navigavable by ships.
river_type[0] = river
river_number = 16
river_min_length = 20
river_max_length = 200

But when simutrans tries to build a river (I guess), this happens:

Message: karte_t::distribute_groundobjs_cities():   distributing groundobjs
Message: wegbauer_t::route_fuer():   setting way type to 127, besch=river, bruecke_besch=NULL
Warning: wegbauer_t::intern_calc_route():   Too many steps (1>=max 1000000) in route (too long/complex)

Message: wegbauer_t::baue():    type=127 max_n=46 start=136,54 end=168,40
Segmentation fault

The same thing seems to happen with the standard way.river.pak. Is there a setting I am missing? Does simutrans require at least two river types?


Edit: Do I need a menu entry?

Try stripping the simuconf entries just to river_type[0] = river and start from there? Pak128 has only this setting and all works.

[Kristian]

Did not work.

Here's one complete river dat to check against...

Neither of the standard river paks work. I wonder if it is something else. Does this
besch=river, bruecke_besch=NULL
mean it is looking for a bridge, perhaps?

[DirrrtyDirk]

Ok, you wrote Simutrans 102.0 - I don't remember, but did that already support rivers? Or were they added later in the nightlies of 102.1...? Have you tried with a later, more actual version yet?

[Kristian]

I may of course have screwed up somewhere, but at least the installed pak64 works with rivers. Let me try to build the whole thing for 102.2.

[prissi]

THe waybuilder has always the possibililty to try bridges and tunnels, but only the AI uses it. THus the NULL message. And if you just copied the dat from pak64, I am a little clueless, why it does not work.

[Kristian]

Ok, thanks for your help. I had the same issues with 102.2, but everything works as it should when I also include the Kanal pak. Apparently, rivers cannot exist separately from canals.

[prissi]

The is certainly an error ...

[prissi]

Channels are no longer required for rivers
