Detailed Description

Place to deposit flags or get the ball to, depending on game type.

Constructor Documentation

GoalZone.new()[1/2]

returns GoalZone

Constructor.

Example:

goalzone = GoalZone.new()
...
levelgen:addItem(goalzone)

GoalZone.new(geom, teamIndex)[2/2]

Arg types: geom: Geom, teamIndex: int  |  returns GoalZone

Constructor.

Example:

goalzone = GoalZone.new(geom, teamIndex)
...
levelgen:addItem(goalzone)

GoalZone constructor.

Default team is Neutral.

Member Function Documentation

containsPoint(p)

Arg types: p: point  |  returns bool

inherited from Zone

Check whether p lies inside of this Zone.

Determines if p is contained by this zone, according to the winding number algorithm. Points which lie on boundary of the polygon are considered inside of it. If a polygon is self-intersecting, this method will return true as long as p lies within some non-self-intersection subpolygon.

Parameters

p	The point to check.

Returns

true if p lies within the zone, false otherwise

getGeom()

returns Geom

inherited from BfObject

Returns an object's geometry.

Returns

A geometry as described on the Geom page

getId()

returns int

inherited from BfObject

Gets an object's user assigned id.

Users can assign an id to elements in the editor with the ! or # keys. Use this function to obtain this id. If the user has not assigned an object an id, getId() will return a negative id that will remain consistent throught the game.

Returns

The object's id.

getObjType()

returns ObjType

inherited from BfObject

Gets an object's ObjType.

obj = TestItem.new()
print(obj:getObjType() == ObjType.TestItem)   -- prints 'true'

See ObjType for a list of possible return values.

Returns

The object's ObjType.

getOwner()

returns PlayerInfo

inherited from BfObject

Gets an object's owner as a PlayerInfo.

Some objects (like projectiles) have an owning player associated. This method returns a PlayerInfo object if there is an owner. Otherwise, returns nil.

This method is intended to be used with bullets and other projectiles, not with game objects like zones.

Returns

A PlayerInfo representing the object's owner, or nil.

getPos()

returns point

inherited from BfObject

Gets an object's position.

For objects that are not points (such as a LoadoutZone), will return the object's centroid.

Returns

A Point representing the object's position.

getTeamIndex()

returns int

inherited from BfObject

Gets the index of the object's team.

Many BfObjects (such as TestItems) are never part of any particular team. For these objects, this method will return Team.Neutral.

Note

Remember that in Lua, indices start with 1!

Returns

Team index of the object.

hasFlag()

returns bool

Does the zone have a flag?

GoalZones can hold flags in some game types. If the current game type does not feature zones that hold flags (e.g. Soccer, ZoneControl), then the function will return false.

Returns

true if the GoalZone is currently holding a flag, false otherwise.

isSelected()

returns bool

inherited from BfObject

Determine if an object is selected in the editor.

This is useful for editor plugins only.

Returns

Returns true if the object is selected, false if not.

removeFromGame()

returns nothing

inherited from BfObject

Removes the object from the current game or editor session.

May not be implemented for all objects.

setGeom(geometry)

Arg types: geometry: Geom  |  returns nothing

inherited from BfObject

Sets an object's geometry.

Parameters

geometry

The object's new geometry.

Note that not all objects support changing geometry if the object has already been added to a game.

setId(id)

Arg types: id: int  |  returns nothing

inherited from BfObject

Sets an object's user assigned id.

Users can assign an id to elements in the editor with the ! or # keys. Use this function to set this id from Lua. When called from an editor plugin, the value passed will be displayed in the editor when the player presses ! or #.

setOwner(playerName)

Arg types: playerName: string  |  returns nothing

inherited from BfObject

Sets the owner of the object.

Parameters

playerName

Name of player as a string.

Note

This method only works if the item in question has already been added to the game via addItem(object). The owner cannot be set beforehand. Also, 'playerName' must exactly match a the name of a player already in the game (case-sensitive).

This method is intended to be used with bullets and other projectiles, not with game objects like zones.

setPos(pos)

Arg types: pos: point  |  returns nothing

inherited from BfObject

Set the object's position.

To set the full geometry of a more complex object, see the setGeom() method.

Parameters

pos	The new position of the object.

setSelected(selected)

Arg types: selected: bool  |  returns nothing

inherited from BfObject

Set whether an object is selected in the editor.

This is useful for editor plugins only.

Parameters

selected

true to select the object, false to deselect it.

setTeam(teamIndex)

Arg types: teamIndex: int  |  returns nothing

inherited from BfObject

Assigns the object to a team.

Parameters

teamIndex

Index of the team the object should be assigned to. (first team index is 1; there is no team 0)

Instead of a team index, you can use the special team enums Team.Neutral and Team.Hostile.

Limitations:

• Will have no effect on items that are inherently teamless (such as a NexusZone).
• Neither Ships nor Robots can be assigned to Team.Neutral or Team.Hostile.
