VisibilityStates calcvisibilityfield (  GameMap *  gamemap, tfield *  fld, int  player, int  add, int  initial, int  additionalEnemyJamming )

calculates the view on a given field. Radar and jamming values must have already been applied to the field! Parameters: gamemap  the map that contains field fld  the field to evaluate player  the player that the view is calculated for add  a bitmapped variable containing the players that share their view with player initial  the initial visibility of the map when starting the game. additionalEnemyJamming  if > 0 run an WhatIf analysis and don't save the result Definition at line 244 of file viewcalculation.cpp. References tfield::building, BuildingType::buildingheight, chsatellit, chschwimmend, tfield::View::direct, ContainerBase::getOwner(), getPlayersWithSharedViewMask(), Vehicle::height, tfield::View::jamming, tfield::View::mine, tfield::mineowner(), tfield::mines, GameMap::player, tfield::View::satellite, tfield::View::sonar, Player::stat, Player::supervisor, Building::typ, tfield::vehicle, tfield::view, tfield::View::view, tfield::visible, visible_ago, visible_all, visible_not, and visible_now.

void clearvisibility (  GameMap *  gamemap, int  reset )

Definition at line 222 of file viewcalculation.cpp. References tfield::view. Referenced by computeview().

int computeview (  GameMap *  gamemap, int  player_fieldcount_mask = 0, bool  disableShareView = false )

completely computes the view Parameters: gamemap  the map that the view is generated on player_fieldcount_mask  bitmapped variable containing the players for whom the changed fields are calculated disableShareView  sharing the view between different players is disabled. Returns: the number of fields that have a changed visibility for the given players. If nothing changes, the map must not be displayed again after the view calculation Definition at line 387 of file viewcalculation.cpp. References Vehicle::addview(), clearvisibility(), evaluateviewcalculation(), and Vehicle::getPosition().

int evaluateviewcalculation (  GameMap *  gamemap, const MapCoordinate &  pos, int  distance, int  player_fieldcount_mask = 0, bool  disableShareView = false )

evaluates the view on a part of the map. Radar and jamming values must have already been applied to the field! Parameters: gamemap  the map that the view is calculated of pos  the central position around which the view is calculated distance  the radius of the circle around pos in which the view is evaluated. The view is calculated in AT LEAST this circle, in reality it is a rectangle containing this circle. player_fieldcount_mask  determines, which players should be counted when the view has changed disableShareView  sharing the view between different players is disabled. Returns: the number of fields which have a changed visibility status Definition at line 344 of file viewcalculation.cpp. References cgp_initialMapVisibility, Player::diplomacy, evaluatevisibilityfield(), Player::exist(), GameMap::getField(), GameMap::getgameparameter(), maxmalq, GameMap::player, DiplomaticStateVector::sharesView(), MapCoordinate::x, GameMap::xsize, MapCoordinate::y, and GameMap::ysize.

int evaluateviewcalculation (  GameMap *  gamemap, int  player_fieldcount_mask = 0, bool  disableShareView = false )

evaluates the view on the whole map. Radar and jamming values must have already been applied to the field! Parameters: gamemap  the map that the view is calculated of player_fieldcount_mask  determines, which players should be counted when the view has changed disableShareView  sharing the view between different players is disabled. Returns: the number of fields which have a changed visibility status Definition at line 323 of file viewcalculation.cpp. Referenced by RecalculateAreaView::addView(), computeview(), SelfDestruct::destruct(), VehicleAttack::execute(), GuiFunctions::VehicleBuildingGui::execute(), Reinforcements::execute(), ChangeBuildingOwner::execute(), JumpDrive::jump(), and BaseVehicleMovement::moveunitxy().

int evaluatevisibilityfield (  GameMap *  gamemap, tfield *  fld, int  player, int  add, int  initial )

evaluates the view on a given field and saves it for that field. Calls calcvisibilityfield for the calculation Radar and jamming values must have already been applied to the field! Parameters: gamemap  the map that contains field fld  the field to evaluate player  the player that the view is calculated for add  a bitmapped variable containing the players that share their view with player initial  the initial visibility of the map when starting the game.
