Line Objects
These were added with version update 2.538. See also the "Obstacles_And_Fortifications" article.
Note that the "Terrastan" map features some additional wall types which are not user-placable.
Types
Jersey Barrier
- This barrier can not be breached
- Infantry is able to cross it
Bremer Wall
- This barrier can not be breached
- Infantry can not cross it
- Blocks LOS
- Does skew with the terrain
HESCO Bastion
These come in two variants, a single-height and a double-height barrier.
Note that in the map editor, one additional row is displayed (the single height shows with two rows, the double-stacked barrier with 3 rows - in the game the lowest row is sunk into the ground to deal with eventual terrain irregularities.
- This barrier can not be breached.
- Does not skew with the terrain (since there is not a single container object available this object should not be used on steep slopes)
Wooden Fences
There are two types:
- Wooden fences "do'' skew with the terrain
Brick Walls
There are three variants:
- "Flint and Brick" and "Brick" walls do not skew with the terrain. On very rough ground you should use the shorter wall segments since these will "fit" the terrain better.
Gameplay Considerations
Please note that this section is - even by wiki standards - work in progress
- If a (in principle breachable) obstacle can be breached depends on the vehicle's mass and speed when hitting the obstacle. Generally, you should only hit walls and fences at low speed.
- Besides by collision, walls may also be breached by using HE/HESH ammunition.
- When designing "checkpoints", you should not place jersey barries into roads, since AI units will not slow down when travelling on the road.. only when they have hit the barrier does the obstacle avoidance kick in.
- All walls (even HESCO barriers) can be shot through.
- Infantry can cross fences - note that there is no "jumping over the fence" animation, they just seem to "tunnel" through it.
- Line objects will not show up on the map page (F5), nor in the mission editor! The reason for this is that fortifications are often of a temporary nature (so would not appear on printed maps) and could not be hidden from the other side (so it would have "perfect intelligence" and could use this to plot artillery missions etc. Mission designers should instead add informational map overlays to show (relevant) fences/lines/barriers.
Considerations for Map Makers
The "wider" line objects do not fit too well on steeper terrain slopes, use the "short" versions instead:
- Note that for HESCO barriers no "short" versions are available.
- Fences, country walls, Jersey barriers and Bremer walls skew with the underlying terrain
