Features include a lineOfSight property:
|
"Tree1": { |
|
"armour": 10, |
|
"breadth": 1, |
|
"hitpoints": 50, |
|
"id": "Tree1", |
|
"lineOfSight": 0, |
|
"model": "mitrees.pie", |
|
"name": "*Tree1*", |
|
"tileDraw": 1, |
|
"type": "TREE", |
|
"width": 1 |
|
}, |
It seems that this propety controls whether units and structures can see through the feature and shoot at objects behind it:
|
; damageable <1|0> Whether or not the feature is damageable, if set to 0, the 'x' cursor will appear instead of the 'attack' cursor |
|
; lineOfSight <1|0> Line Of Sight. Whether of not units and structures can see through them and shoot at objects behind them |
|
; startVisible <1|0> Whether or not the feature is visible even if you haven't explored that area of terrain yet |
However, this property doesn't seem to do anything in the source code currently. It seems that visibility.cpp is the right place to implement it?
|
{ |
|
const MAPTILE *psTile; |
|
halfway = current + (next - current) / 2; |
|
psTile = mapTile(map_coord(halfway.x), map_coord(halfway.y)); |
|
if (TileHasStructure(psTile) && psTile->psObject != psTarget) |
|
{ |
|
// check whether target was reached before tile's "half way" line |
|
part = halfway - start; |
|
partSq = dot(part, part); |
|
|
|
if (partSq >= distSq) |
|
{ |
|
break; |
|
} |
|
|
|
// allowed to shoot over enemy structures if they are NOT the target |
|
if (partSq > 0) |
|
{ |
|
angle_check(&angletan, oldPartSq, |
|
psTile->psObject->pos.z + establishTargetHeight(psTile->psObject) - pos.z, |
|
distSq, dest.z - pos.z, direct); |
|
} |
|
} |
|
} |
