Agents sliding in idle pose when other agents collide

[adamsale]

Hello Yeah. I hope you are well! 
I'm having a basic issue with miArmy and the idle Cycles, or any still cycle, and I've never really figured out a solution. 

Agents that are supposed to be playing idle cycles, get pushed around by other agents who collide with them as they attempt to autoavoid. 

As an example, an agent with two actions, walk and idle, I place them in a 5 x 5 configuration side by side with enough distance between them. 
I have the idle as a default action

In a second decision I use agent noise id 0 - 1 to randomly playback a walk action, while the rest stay idle. 

The idle agents at the front of the group inevitably get pushed around by the walking agents at the back of the column as they pass by, even though they shouldn't be moving. 

Is there a specific way to prevent idle cycled agents from moving at all, like pinning them in the spot, because it tends to look odd when they slide around when they shouldn't. 
It seems like pinning idles in place should be a default. 
I set up the actions correctly for the idles, using still, cycle, and the blocking in the action editor looks correct, so I'm a bit puzzled. 
This happens on most of the scenes I work on to some extent, so it makes me wonder what I'm doing incorrectly. 
In a big crowd, this is less obvious, but if the idle agents are in the front of a crowd in view of the camera, it stands out. 



I'm also wondering if miArmy works best at a specific scale. 

I tend to build by scenes in centimetres, so that my agents are approximately 150 = 200 cm tall for human proportions. 
I noticed in your example scenes, your agents are approximately 30 cm tall and I was curious what units you might have been working with
Is this intentional, or does scale matter in miArmy?

Hello Adam,

1.
Is that possible to disable the auto avoid and use the logic to control the logic?

No, there is no limitation of the scale or unit, you can use it freely.
The height of the agent in the example is not intentional too.

Cheers,
Yeah

Hello Yeah, So to clarify the auto avoid bypasses in simple cases the need to use the sphere logic to avoid collision?
So if I want more accurate collisions, building up a number of sphere sentences.. someone in my sphere range and sphere distance would give me more accurate avoidance and prevent sliding of still agents?

If using the more advanced sphere logic, is it important to make sure the auto collision avoidance is disabled? Does leaving it on, confuse the sphere logic or conflict with it?

I had been playing around with the auto avoid and sphere logic, but wasn't getting the results I wanted. I will try again though, and if still problematic will post a simple scene.

Thanks!

To add to this, I've used both the sphere logic and the direct engine logic and had similar sliding, but as mentioned will try with the enable auto avoid turned off this time. 

[adamsale]

That does the trick. Turning off auto avoid while using output logic works perfectly. I guess I thought the two could co-exist. Thanks Yeah. That really helps clarify. The idle agents are no longer sliding.
One thing I also noticed is having to really get the scale and smallest rratio correct to prevent agents penetrating agents as they pass by one another.
