Used to set terrain types or change passability of a square.

 

!!TRx/y/l:XXXX;	Set a Terrain type or change passability of a square at the specified x,y,l location.
!!TR#:XXXX;	Alternative method to above. Uses indirect reference: x=v[#], y=v[#+1], l=v[#+2]

E$;	Mark the square as an object entrance (yellow trigger square)    $ = 0 means yellow trigger.      $ =1 means  no yellow trigger (1).
E?$1/?$2/?$3;	Get/check object entrance position This command lets you get position of entrance of an object (x/y/level) If there is no object at the position, the coordinates passed to TR reciever are returned. If you pass coordinates of a red square of an object to it, it would return croordinates of its entrance.
G?$;	Return the topmost terrain overlay. You may only use GET or CHECK syntax. (See Format TO)
G$1/$2;	Get type & subtype of topmost terrain overlay   $1 - type   $2 - subtype Type 40 subtypes starting with 10000 are recognized as new WoG terrain overlays. You can give them any effect with a script.
P$;	Set/check/get a passability of the square (red square)    $ = 1 means passable.       $ = 0 means not passable.
T$1/$2/$3/$4/$5/$6/$7/$8;	Set/check/get a terrain type    $1 - type of land    $2 - subtype of land    $3 - type of river    $4 - subtype of river    $5 - type of road    $6 - subtype of road    $7 - type of mirror    $8 - Bit mask of accessability Comments: above.
V$;	Set/check/get a visibility of a square (one bit - one color) Comments: This is similar to the UN:S and UN:H but for individual squares and you can check or get the value. Also, monsters have sight (1 hex)and this can be enabled or disabled -- they have a bit value number of 256.

7. Mirror Type:

Bits: 76543210
--CcBbAa ('-' means no matter)
a - vertical mirror for land type (not for all land types)
A - horizontal mirror for land type (not for all land types)
b - vertical mirror for river type
B - horizontal mirror for river type
c - vertical mirror for road type
C - horizontal mirror for road type

More Explanations about mirror type
Say, this is:

This will be shown if you use mirror=0

Then set first bit (mirror=1). This will mirror the square vertical to:

Or set second bit (mirror=2). This will mirror the square horizontal to:

Or set both bit (mirror=3[2+1]). This will mirror the square h and v to:

The same about mirroring the river and road.
River h mirror=4
River v mirror=8
River both mirror=12[8+4]
Road h mirror=16
Road v mirror=32
Road both mirror=48[32+16]
You can combine all mirroring.
Say square mirror h, river mirror v and road mirror h and v mirror= 57[1+8+16+32]

8. bit mask of accessability
mt: bit mask of accessability
Bits: 76543210
???E???P ('?' means no info)
P - passability
E - enrtance
These bits may be set individually by TR:P and TR:E commands.
