reported earlier Trucks stuck on bridges...

[shabo]

So I am developing a convoy mission and I am having a heck of a time making my AI stay in a convoy and crossing bridges. It seems they get all bunched up and stuck on them half the time. What is the "trick" to getting them to properly cross a bridge in a orderly fashion? I have the column going a whopping 5 kts when approaching the bridge and they still manage to get all bunched up and half of them get themselves into a situation where they wont even cross the bridge. Please help!

Yea, AI has a hard time crossing bridges sometimes. I think it happens more often when enemies are near, but it can happen any time.

 

You can have them simply go offroad and drive around the bridge. Most streams can be forded by most units. That's what I do. You can even work it into the mission storyline, like, the enemy blew up all the bridges or something. In fact, if a bridge is blown up along the route a unit will use, they automatically revert to their last waypoint, and try to bypass the bridge.

they are crossing the border in NW Georgia, they can use the bridges but they get clogged and since that river leads all the way to the mountains and must be deep they just head east to the mountains for HOURS, I dont have that kind of time to spare for this mission. Just need a better AI from ED I guess

The size of the convoy and the type of units in the convoys affect the 'elastic band effect'. Also the speed of the convoys affect the yo yoing if the slowest unit is unable to achieve the ME set speed. I usually set a convoy to a maximum size of 6. Use triggers to have one convoy group follow another at a set distance.

 

Convoys are frustrating and sometimes expermimentation is the only answer. Welcome to the joys of mission building :)

[shabo]

No kidding right? Man it is trick to get them to do anything once it comes down to a bridge, even with them going slow

[Wrecking Crew]

Yep. Decreasing the number of units is helpful. But I just route mine around the bridges with enough waypoints to get them back onto the main road I want them to be on.

 

One thing that this issue led me to do is to lead convoys with a jeep type of vehicle, or two, and then a troop truck, followed by the armor and air defense.

 

 

You said your convoy will go for hours... add a few more waypoints near the river crossing and set the waypoint at the crossing to Off Road, Vee, or something like that. Then on the other side of the river have another On Road waypoint. Maybe that will do the trick.

Ive tried just about anything, problem I run across is sometimes they will come to a deep section of the river and some will cross it, some wont. I am going to try the smaller groups. Thing is I want 2 tank battalions to get into a nice battle and when half of them stay on one side and the other half traverse the river it makes it near impossible to achieve the results I want.

[Raven68]

It may be an issue that has been reported and a none issue Also it may not be repeatable, but setting a "on the fly" way-point for a column of tanks in a modified mission from a stock mission. a single M1A2 tank in the group has a problem crossing a bridge. I am providing the mission and track file as well as a pic to illustrate the problem.

A lot of these are not easy to repeat... sometimes it has to do with the AI trying to pass something on the bridge.

 

This bug is my "favorite", personally:

[Evil.Bonsai]

I'm surprised they bothered to use a bridge; when I've tried telling a column cross a river, I click on both sides of bridge but they always decide to use their own 'ford' path, somewhere on either side of the bridge. Weird that they included multiple 'columns' to choose but no 'follow road'

[Raven68]

Yeah it's pretty funny Speed. It reminds of a party scene, in a congested neighborhood with folks having nowhere to park!! :D

Yes-yes, try next scenario:

select one tank from group and run in manual mode over large bridge.

It's must be large, over wide river.

On bridge, press "c" mode , and switch to map view F10.

In some case all groups start _flying_ on maps.

Much speedy than some f-15 ! :) Look like tanks use warp-9 factor from startrek

p.s.

remember - use large bridge. Probably depend from group speed and course.

[gunterlund21]

Its even worse if you look in detail at the path it creates on bridges. At the entrance to the bridge the game has the AI doing a loop back at the entrance to the bridge so your whole column will get in a huge jam if the group is too big. What Ive found to work is place a waypoint on each side of the bridge. When the group approaches the bridge slow them down to under 10km so they pass slowly to negotiate the jam.

[71st_Mastiff]

I had a 20 column convoy stop on the bridge and they all dog pilled. :pilotfly:

[Wrecking Crew]

There is an Advanced Waypoint Action for disperse on attack (can't remember exactly what it is called). For my convoys going long distances and especially across bridges, I will set that disperse attribute False early in the convoy's path.

 

Also, air defense vehicles will stop to engage a/c, and if these units are in an armor column then that can cause the convoy to get out of sequence. If that happens on a bridge then it may cause these jamming issues. Could use ROE = Weps Hold here, or Alarm State = Green, to prevent the AD units from engaging...

 

I've started separating my AD units from armor - make two groups instead mixing them. Some day I will need to investigate a zone following approach with a moving zone on the armor and the AD set to follow.

I hope ED will fix the AI soon... as it is now my convoy of tanks got stuck on the first bridge :(

[STP Dragon]

Sorin:

 

Please strip your mission down so it only contains the convoy and move the convoy in front of the bridge so the isue is reproducable in a view minuts/seconds.

Then send it to me. I will try to reproduce the isue in the testers version and add it to the bug tracker.

[Sorin]

STP Dragon please find attached a track that shows that tanks cannot find their way, even I have tried to set the path very reasonably. The last tanks in the column got stuck on the bridge.

Tanks cannot find their way.trk

[STP Dragon]

Thank you Sorin, I reproduced it in the testers version and reported it to the bug tracker.

 

Workarround: Add the waypoint some meters away from the bridge. If you add it to close to the bridge the route gets messed up. You can see this on the F10 map.

[Sorin]

OK, will do.

[sorcer3r]

Anyone bigger? ;)

 

Seems to be a problem with bridges.

[sobek]

WTH? Some additional information? :)

[ApoNOOB]

Haven't seen that yet, but units often get stuck on bridges - I need to spawn into them and move them a bit to fall down the bridge. Sometimes they fall on their back and just get up and drive of like nothing else. But they can't get over a bridge! xD

[Devrim]

I don't surprise this after seeing AI jets flying towards to ground and again sky constantly...

[sorcer3r]

WTH? Some additional information? :)

 

 

They were sent via combined arms slot over this bridge. The ground force commander couldn't see the "tower". He could only see all tanks in one position.

For the other clients it looked like on the screenshot. :)
