Info: Infantry metrics

[x3kj 1247]

For making structures and also maps, that work well ingame it's important to know what metrics the infantry has, what it can navigate and so on.

Today i made some tests with following results:

 

Wall heigth:
50cm - look over:"high prone", shootover: "high prone", totally covered: "regular prone"

80cm - look over:"regular crouch", shootover:"regular crouch", totally covered:"high prone" (the sitting animation). Bipod deployable.

110cm - look over:"high crouch", shootover:"high crouch", totally covered:"low crouch". Bipod deployable.

130cm - look over:"low stand", shootover:"regular stand", totally covered:"high crouch". Bipod deployable.

145cm - look over:"stand", shootover:"high stand", totally covered:"high crouch". Bipod deployable.

the heigths listed here are the VR Obstacle objects, you can use them as reference

totally covered and shoot over depends on what heigth the target is at. I used Infantry targets at same heigth (flat VR map) at 100m as reference for this.

 

Ceiling/ Gap heigth (e.g. in a fence, wall, door frame or room height)

20cm - can shoot below in "low prone", enemy feet past 50m barely hittable

50cm - minimum for moving through in prone

110cm - minimum for moving through in crouch, BUT bad clipping with head. Better use 120cm

170cm - minimum for moveing through in standing, BUT bad clipping with head. Better use 180cm (no clipping, even in high stand)

 

Corridor Width:

90cm - minimum width for walking through. Turning in "regular stand" and "regular crouch" is possible but very twitchy (due to wall collisions of the weapon). Better use 100cm. Crouched turning causes head to clip through wall

130cm - minimum for turning in "low crouch" and "high crouch" (but twitchy). Better use 140cm.

170cm - minimum for turning in "regular prone", but twitchy (only is gone at 200cm). No "high prone" or "low prone" turning possible.

200cm - minimum for turning in "high prone" and "low prone" , no twitching.

 

Corridor Width - walking past another standing soldier close to the wall, both facing along the corridor:

150cm - only using "step" function - pretty glitchy.

160cm - only using "step" but only 1 step required

180cm - passing without "step" possible.

note that depending on orientation and stance of both soldiers, it may be easier or harder to pass

When 2 seperate buildings/objects walls are 180cm apart from each other, the AI seems to be able to navigate this corridor (better use 2m in this case though). For interior of buildings (with paths LOD and roadway LOD) smaller corridors are no issue for AI, because they can walk through Geometry when on a path 

 

The tests where conducted with the 1x1x1m VR Block, and the 10x5x4m VR Block. So if their geometry doesnt properly match these results are slightly sqewed.

 

Edit: It seems that for the VR Block skews the results a little bit (or the crouched stance got increased geometry model in some patch). I was not able to turn 360° in a gap of 1m in regular crouched stance inside a building. 1.1meter is fine however.

 

Weapon Deployment Limits:

You can definitely deploy weapons between 0.8m heigth (maybe even lower) and 1.45 meter heigth (maybe even higher).

You need minimum clearance for the muzzle when deployed. Imagine you place a 130cm tall "resting block" in front of a 2m tall wall and you try to deploy the weapon on the resting block, facing in the direction of the wall. You will only be able to deploy if the space between restingblock and wall is somewhere between 35cm and 40cm (37.5cm worked in my case). Of note here is that this space needs to be in the firegeometry LOD, normal geometry LOD does not affect this particular case.

 

Walkable Slope:

Slope angle on Roadway LOD to be still walkable

up to 50° from horizontal - no problem getting on the slope and walking on it

at least up to 65° from horizontal (possibly steeper, test stopped at 65°) - can walk on the slope itself, but difficulty getting on it from horizontal level. Without using "step over" key (or glitching/walking diagonal) it's not possible to get on the slope from a horizontal place, when standing at the bottom.

Generally avoid steep slopes where possible, because infantry are "turboboosted" when walking up or down (looks real goofy), as their walking speed is constant and referenced to the horizontal plane.

 

Feel free to contribute 🙂

Thanks for publishing that and doing all the research - hope that helps out terrain object makers.

Should be a sticky!

Fantastic resource. Thank you.

I know its a old post but I would like to thank you anyway as it is hard to find this stuff when making new buildings. Again, thank you.
