Bridge Traffic Problems

[shagrat]

Well, just try to have a car follow the road under a railway bridge...

This utterly breaks one of my favorite missions, where "follow road" is crucial for carefully timed patrol patterns. :cry:

 

When a vehicle reaches the opposite end of the crossing bridge it "warps" on top of it... end of patrol!

 

This is the result:

 

Start the mission, enter observer slot select HMMVV on F10 Map, press F7 and enjoy the show.

Sigh.

This is exactly what happened in a thread that I posted HERE along with Ranger79's conclusion. The school bus was last seen sitting on top of a RR bridge and that borked the mission.

Bridges are a major problem in DCSW. Really funny stuff happens there regularly, regardless of whether the AI just wants to cross the bridge or is driving through underneath it.

Especially if something irregular happens, like combat for example. Tanks driving over a bridge, getting attacked and dodging is hilarious. And also sad.

I prepared 2 missions + tracks this morning to open a bug on rail-road bridges before I saw the numerous posts about issues with them...

 

 

 

You can reproduce easily...

 

 

But no issue with over types of bridges (I mean road over rail is OK) as I did in Gori:

 

Only the last bridge got into trouble...

Would there be any way to remove the rail over road bridges from the map and if so would that be a temporary fix for the problem? I wonder what would happen if you bombed the bridge prior to the arrival of the oncoming vehicle? Galevsky why don't you try that on your test mission to see what happens and post your results.

Hey guys, this has been reported, I have asked to escalate it as it pretty much is a block right now.

[galevsky06]

Thanks a lot, SiThSpAwN

[Rangi]

Thanks SiTH, this one has been driving me crazy and I ended up giving up on my Su-25T campaign after months of work because this bug is so silly, bad.

[ENO]

I hope that while they're fixing this one they stumble into some fixes for a few other path finding issues.

The rail bridges are the worst, but vehicles will fall through other bridges and do funny things like drive on water as well. And with the mission with the bus that is invincible until it reaches its destination we tried destroying the bridge to get it moving again. No such luck. It continued to sit there. Once this happens the mission is doomed.

Thanks SithSpawn. Much appreciated!

I really believe a number of them are just a limitation of the map and the fact that we are pushing it beyond its design limits now... :unsure:

[JNASova]

It`s not only rail bridges.

Any bridge will do ...

 

[shagrat]

I tested what happens when driving the vehicle in CA. Manually driven it follows the road no impact. Even if I drive the Vehicle "over" the edge of the bridge after it got stuck, it falls down erects and drives on... so it definitely is something in the route finding AI. :(

Edit: tested with today's openbeta, so it is not fixed yet.

Convoys Brutal (beating dead horse)

 

 

I know its been mentioned a million times but its plagued DCS for so long now that I just want reinforce how badly this needs addressing -- we can't make missions and keep the community alive and healthy with more and more complex missions via scripting if something as simple as going across a bridge is so utterly broken - I would trade EDGE for convoys working properly! :doh:

[LFCChameleon_Silk]

this is a very important issue, its not just DCS that has a hard time with bridges I dunno if i have ever seen AI path find across bridges properly in any game, should just remove the damn things. and make it consider it a road...

[Winfield_Gold]

I am sure this issue has been addressed many times in many threads related to this same problem. I have been assured that the problem with ground units and bridges has had special attention paid to it with EDGE.

 

Also new ground models that are in the works is also a reason that road\bridge issues are being resolved.

 

As frustrating at it may be, rest assured that the problem will be resolved in the "near" future.

[Galwran]

I'm also jumping on the bandwagon and begging to get new formations with more separation between vehicles. Something like "on road" and "on road - sparse" with at least three times the separation that they currently have. Off-road formation should also have at least 50 meters of separation, sometimes more than that.

 

Heck, it might even solve some collision problems :smilewink:

[shagrat]

+1 Make them non collidable objects for vehicles and let them drive through bridges... problem solved!

[LFCChameleon_Silk]

yea well I'm gonna be a cynic and say that EDGE and pathfinding will continue to be a problem for years to come -- tried some scripting in Arma 3 awhile back and that engine has same degree of crap with bridges... felt like playing some yakitty sacks watching AI try to path... if it was easy it would have been fixed long ago.. but thats why I am brining it up so much and how many bridges are there in NEVADA? isn't it like all desert... lots of streams to cross i suppose.

 

I say this with love in my heart, to have AI pathfinding work great with or without EDGE would be very nice.

Who has assured you? Where did you get your info from?

Perhaps he is talking about these posts. If that is the case, I think he is reading too much into them. (Eno's post included for context).

 

AI on road ends up on top of railway bridges!!!

The back half goes over the bridge... front half goes around it. Turns the convoy inside out. Yahoo.

 

 

 

 

 

 

 

Half the convoy gets stuck on the first bridge in the distance... next half has to go around an obstacle and warps down to the bottom of a cliff... ends up path finding itself under a bridge where it promptly warps onto the bridge and gets stuck

 

 

Military spacing. By now, the lead vehicle is in the middle and the whole convoy is f'd. Suffice to say this was the result of the issue on photo 1.

 

 

This is actually not related to any incident at all- the vehicles are in the correct order- this is more prevalent on the narrow roads. How that matters- only the devs know.

Just adding emphasis... this is really, really, really killing it.
