Class BattlefieldSight<C extends BattlefieldCell>

java.lang.Object

fr.arakne.utils.maps.sight.BattlefieldSight<C>

Type Parameters:

C - The battlefield cell type

public final class BattlefieldSight<C extends BattlefieldCell>
extends Object

Utility class for compute line of sights Note: The used algorithm is not exactly same as the client's one, some differences can occurs Algorithm : - Get coordinates of the two cells - "draw" a line between the cells : - Compute the vector between those cells - Creates the function : Y = ySlope * X + yAtZero with - For each X between the cells compute the related Y using the function - Increments Y cell by cell to reach the computed Y - Check the cell line of sight value - If the sight is blocked, return false

Method Detail

between

public boolean between(C source,
                       C target)

Check the line of sight between those two cells This is equivalent to sight.from(source).isFree(target) Usage:

 final BattlefieldSight<FightCell> sight = new BattlefieldSight<>(map);

 if (!sight.between(fighter.cell(), target.cell())) {
     throw new Exception("Target is no reachable");
 }
 

Parameters:

source - The source cell

target - The target cell

Returns:

true if target is not blocked

See Also:

CellSight.isFree(BattlefieldCell)

between

public boolean between(CoordinateCell<C> source,
                       CoordinateCell<C> target)

Check the line of sight between those two cells This is equivalent to sight.from(source).isFree(target) Usage:

 final BattlefieldSight<FightCell> sight = new BattlefieldSight<>(map);
 final CoordinateCell<FightCell> from = new CoordinateCell<>(fighter.cell());
 final CoordinateCell<FightCell> to = new CoordinateCell<>(target.cell());

 if (!sight.between(from, to)) {
     throw new Exception("Target is no reachable");
 }
 

Parameters:

source - The source cell

target - The target cell

Returns:

true if target is not blocked

See Also:

CellSight.isFree(CoordinateCell)

from

public CellSight<C> from(CoordinateCell<C> cell)

Get the line of sight of a cell Usage:

 final BattlefieldSight<FightCell> sight = new BattlefieldSight<>(map);
 final CoordinateCell<FightCell> current = new CoordinateCell<>(fighter.cell());

 sight.from(current).to(target.cell()).forEachRemaining(cell -> {
     // Iterator on line of sight
 });
 

Parameters:

cell - The cell to check

Returns:

The line of sight instance

from

public CellSight<C> from(C cell)

Get the line of sight of a cell Usage:

 final BattlefieldSight<FightCell> sight = new BattlefieldSight<>(map);

 sight.from(fighter.cell()).to(target.cell()).forEachRemaining(cell -> {
     // Iterator on line of sight
 });
 

Parameters:

cell - The cell to check

Returns:

The line of sight instance
