Iron fences,bushes or other objects stop vehicles immediately
Reviewed, NormalPublic

Description

*Reproducibillity* Always

That a problem since OPF you drive with any vehicle against an Iron fence,bush or something else and the vehicle will stop immediately or lose lot of speed ca 85% even when the rammed object is lighter than the vehicle

Reproducibillity* sometimes

This effect is unrealistic and create new problems, becourse of the new phisicX engine sometimes the vehicle will flip over when you ram objects like iron fences

The forum subject long waits for the answer - What setting of the server creates a problem?

It already shoud be fixed?
It was the wrong weight for the fences and bushes

Still there is a server where it works in strange ways. How this can be implemented on the server? Which option is activated?

As before, dependences are not found, the method of adjusting is not found.

Ok your video shows one thing arma calculates the impuls. Sry but hitting a big bush with almost 80km/h is hard. Just imagine hitting a small tree on 80km/h. That it damages the wheels is a matter of the hit box. But that would definetly damage parts of the chassi and axis

There never was something to adjust. I said they changed it. It was much worse earlier. Check out AiA Terrainpack there are the old configs

@TheMasterofBlubb I have no access to the server. I am forced to address administrators of servers where this problem exists. Administrators can't fix a problem as don't know where it is adjusted and what emergence of a problem depends on. Where it is possible to find the explanation in this question?
Players often receive damage to health, on speed of 10-20 km\h. At this speed the car can lose wheels or turn over. Such settings of the server strongly spoils a game.

The damage on the player is defined by the vehicle. There is a value for hit resistance (dont know the exact name though). The bushes have a specific weight its low but there. As you hit them they try to remain unmoved (rl physics) the faster you hit it the more energy it can absorb. Its pretty realistic currently (counting for flaws in the engine)

@TheMasterofBlubb There are servers where a ratio "speed \damage" look isn't realistic.
This balance well works at the majority of servers. Instructions are necessary, where and as to adjust it.

What you describe looks to me like something else.
What i experienced is that when the server is too weak it creates microlag in the physics. Could it be that the problem occurs on servers with mostly weak cpu? Im not sure if you can change that so easy. What you can do is upper that armor value but that would be a mod and would obly effect the dmg to the players. To lower the damage to the vehicle you need changes to the dmg model. To lower the effect loosing speed you need to higher the mass of the vehicle.

I didn't assume that it can be server lag. It steadily repeats, throughout all game. Doesn't depend on the general load on the server.
If it is lag, I assume that except this problem, there could be also other problems connected with server lag. But there are no other problems.
If to start a mission locally - this problem is absent. On a combination of all results, there was an assumption that settings of parameters of a game on the server have influence on the weight of bushes, fences....

On your server bushes, fences... well works, there is a balance of collisions - speed \damage.
Video from your server https://youtu.be/UDzGBmVPd6o
On the ATV, speed ~ 40km \h, I easily pass bushes, and there is no loss to health.
On my video (earlier in this branch), I receive injury of the car and a loss of health at a speed of collision is lower 40km \h.

The server has a i7 6700 on 4GHz. 1server 3 HC. Arma is completly loaded in to ram with a ram disk.
I figured out that when arma is not on the ram. So its used from a SSD it has micro lags even though the cpu is getting bored.

Lex added a comment.EditedApr 11 2017, 5:28 PM

Why my doubts that it is server lag:

  • collision happens to full effect of collision (soft blow, chips.....)
  • it never looks on a miscellaneous (I have sometimes counted blow sometimes isn't present) it isn't present.

Perhaps administrators of the server could correct a problem. Long ago I wasn't on this server. I have recorded video, I one on the server. Everything looks good.

The other day I will add video when there are many players. We will compare results.

Maybe the hardware changed

This video has a problem that was recently solved
https://youtu.be/2zJBqQmidHE
About what I thought. Perhaps at speed, we do not have time to see, bushes manage to damage the machine before the bush itself breaks down.

@Wulf In the editor, you can create a script, for example, there is a big fight between AI infantry and equipment.
Starting the mission, the mission will be done with some lag. At this point in time, you can reproduce how the bushes break the wheels of the car.
The script of the breakage of the bush lags behind, breaks the car and takes away the health of the character.
Here is the result on the video, as I have reproduced.
https://youtu.be/BuZY6zqF8uk
So it happens on servers where there are more than 10-15 players, a lot of AI, a lot of actions and events.

I would say that this bug depends on the server fps. The lower they are the higher is the occurence of the bug
