Member Function Documentation

getCaptureZone()

returns Zone

inherited from Item

Returns capture zone holding the item.

Many games do not feature capture zones. For those games, this function will always return nil. Currently only FlagItems can be captured.

Returns

Zone where the item has been captured. Returns nil if the item is not in a capture zone.

getCurrentHealth()

returns num

Returns the item's current health. This will be between 0 and the result of getFullHealth().

Returns

The current health .

getFullHealth()

returns num

Returns the item's full health.

Returns

The total full health.

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.

getRad()

returns num

inherited from Item

Returns the radius of an item.

Returns

The radius of the item. For a Teleporter, this is the radius of the entrance. For a ForceFieldProjector, this is the radius of the base.

getRotationSpeed()

returns nothing

Get the Core's rotation speed factor.

Returns

The rotation speed.

getShip()

returns Ship

inherited from Item

Returns the ship where the item is mounted.

Most objects cannot be mounted. For those, this function will always return nil.

Returns

Ship where the item is mounted. Returns nil if the item is not mounted.

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.

isInCaptureZone()

returns bool

inherited from Item

Is item in a capture zone?

Returns

true if item is held in a capture zone, false if it is not.

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.

setFullHealth(health)

Arg types: health: num  |  returns nothing

Sets the item's full health. Has no effect on current health.

The maximum health of each panel is the full health of the core divided by the number of panels.

Parameters

health

The item's new full health

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.

setRotationSpeed(speed)

Arg types: speed: int  |  returns nothing

Sets the Core's rotation speed factor.

The rotation speed is a multiple of the default (1x). The default time it takes for one rotation is 16384 ms. Therefore, the rotation time is:

16384 ms / speed

Speeds of 0 (stopped) to 15 are allowed.

Parameters

speed

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.
