Setting: LOSIndirectDotted (default true, game default false)
Setting: LOSNoAttackDotted (default true)
Setting: LOSMeleeDotted (default false)
Setting: LOSClearDotted (default false)
Setting: LOSBlockedPreDotted (default false)
Setting: LOSBlockedPostDotted (default false)When true, the line(s) will be dotted. When false, the line(s) will be solid.

Setting: LOSMeleeColors (default "#F00,#0FF,#0FF,#0F8,#F00")
Setting: LOSClearColors (default "#F00,#0FF,#0FF,#0F8,#F00")
Setting: LOSBlockedPreColors (default "#D0F,#D0F,#D0F,#D0F,#D0F")
Setting: LOSBlockedPostColors (default "#C8E,#C8E,#C8E,#C8E,#C8E")
Setting: LOSIndirectColors (default "#F00,#0FF,#0FF,#0F8,#F00")
Setting: LOSNoAttackColors (default "")When non-empty, set the colour and style of various targeting lines. Obstructed lines has two parts. The part before obstruction is Pre, and the part after is Post.
Colours are either empty or in HTML hash syntax. For example "#F00" = red, "#0F0" = green, "#00F" = blue, "#FFF" = white, "#888" = grey, "#000" = black. Four parts means RGBA, while three parts mean full opacity RGB. Supports full and short form. e.g. #28B = #2288BB = #2288BBFF.
Colours and only colours can also vary by attack direction, separated by comma. The directions are Front, Left, Right, Rear, and Prone, in this order. If less colours are specified than direction, the missing directions will use the last colour. For example "red,cyan,cyan,green" will result in front red, side cyan, and back/prone green.

Setting: LOSHueDeviation (0 to 0.5, default 0.04)
Setting: LOSHueHalfCycleMS (0 to 300k, default 2048)
Setting: LOSBrightnessDeviation (0 to 0.5, default 0.1)
Setting: LOSBrightnessHalfCycleMS (0 to 300k, default 1024)When non-zero, the targeting lines will have animated colour, such as dimming and brightening.
"Deviation" is the range of animation. For example cyan has a hue value of "0.5", and a hue deviation of "0.1" will causes it to animate between "0.4" and "0.6", or a cycle of green <> cyan <> blue. Thus, a high hue deviation can cause line colours to mix up and lost their meanings.
Brightness also works on a scale of 0 (black) to 1 (brightest) with the animation range determined by the colour and deviation setting.
"HalfCycleMS" is the milliseconds needed for hue or brightness to complete a half cycle. In the above example, that would be the time it takes to go from green to blue.
The default cycles are power of two for faster modulo calculation, but you can use any integer.

When the mod "Firing Line Improvement" is used, it will override the game's code with its own, effectivelly disabling these colour and animation settings.

Setting: LOSWidth (0 to 10, default 2, game default 1)
Set width of all targeting lines (direct, indirect, blocked, can't attack etc.). Game default is 1 Mod default is 2.

Setting: LOSWidthBlocked (0 to 10, default 1.5, game default 0.75)
Set width of obstructed part of an obstructed targeting lines, which is normally thinner than other lines by default. Game default is 0.75. Mod default is 1.5.

When the mod "Firing Line Improvement" is used, it will override this mod's widths.

Setting: LOSMarkerBlockedMultiplier (0 to 10, default 1.5)
Scale the obstruction marker of targeting lines, the "light dot" that split the obstructed line into two. 2 means double width and height, 0.5 means half-half. Set to 1 to leave at game default. Set to 0 will not remove them from game but will effectively hide them.
When the mod "Firing Line Improvement" is detected, this setting will be disabled to avoid conflicts.

Setting: ArcLinePoints (2 to 127, default 48, game default 18)
To some sharp eyes, it is easy to see the hard corners of the arc of indirect targeting lines. Lines are quick to draw, so this mod will happily improves their qualities for you. Set to 2 to make them flat like other lines. Set to 18 to leave at game default.
When the mod "Firing Line Improvement" is used, the indirect fire arc cannot be modified.
