| Name | Type | is_array | initial_value |

| WallType | unitcode | Yes | UnitTypeNull |
WallSize
this global real must be initialised with the wall size
it is used to know how far the system need to look to find the nearby other walls
WallType
this 16-sized unit-type array must be initialized with the correct wall type :
the number following the wall name give its connections: Wall NSEW
N for north, S for south, E for east, W for west, they have value 0 or 1
if the value is 1, then the wall is connected to this direction, else it isn't
so the array index of a wall type is 8*N+4*S+2*E+1*W
Triggers "Wall entering/leaving the game"
the triggers updating the walls are performed for built and death event
you've to add events to adapt them if you use others events like summon
how does it work:
each time you built a wall, the first trigger check the nearby other walls to update it
each time you built or destroy a wall, the nearby other walls connection are also updated
Function "IsConnectable"
this function allow you to edit conditions for the connection between two walls
in this sample map, two walls can be connected only if they're owned by the same player
but you can remove this condition to allow connections between all walls
you can also edit it to allow connections between walls of the same force
Model
you should import your own wall's models
this map use sample unproper models you should not use
(you should not use the dummy trigger too)
