Method Detail

getAreaSize

public IVector2 getAreaSize()

Returns the size of the simulated area.

Returns:

size of the simulated area

setAreaSize

public void setAreaSize(IVector2 areasize)

Set the area size.

Parameters:

areasize - The area size.

getBorderMode

public String getBorderMode()

Get the border mode.

Returns:

the border_mode

initSpaceObject

public void initSpaceObject(ISpaceObject ret)

Init an object in this space.

Overrides:

initSpaceObject in class AbstractEnvironmentSpace

addSpaceObjectType

public void addSpaceObjectType(String typename,
                      IPropertyMetaDataSet mobjecttype)

Description copied from class: AbstractEnvironmentSpace

Add a space type.

Specified by:

addSpaceObjectType in interface IEnvironmentSpace

Overrides:

addSpaceObjectType in class AbstractEnvironmentSpace

Parameters:

typename - The type name.

mobjecttype - The properties (map of maps with name->name/value/dynamic/event).

setPosition

public void setPosition(Object id,
               IVector2 pos)

Set the position of an object.

Parameters:

id - The object id.

pos - The object position.

getDistance

public IVector1 getDistance(IVector2 pos1,
                   IVector2 pos2)

Get the distance between two positions.

Parameters:

pos1 - The first position.

pos2 - The second position.

getDistance

public IVector1 getDistance(IVector1 pos1,
                   IVector1 pos2,
                   boolean isx)

Get the distance between two coordinates (x or y).

Parameters:

pos1 - The first position.

pos2 - The second position.

calculateDistance

public IVector1 calculateDistance(IVector1 dx,
                         IVector1 dy)
