Constructor Details

EntityEmitter

public EntityEmitter(IEntity entity,
 String emitterResourceName,
 boolean dynamicLocation)

Constructs a new EntityEmitter from a given emitter resource that follows an entity's location.

Parameters:

entity - The IEntity to which this emitter is bound.

emitterResourceName - The name of the configuration for this emitter. If the Emitter has been added to the game resource file, it is loaded from there by name. Otherwise, the EmitterLoader will search the Resource folders for a file with the emitterResourceName.

dynamicLocation - If true, the emitter follows the entity's location; if false, it remains at the location where it has been created.

EntityEmitter

public EntityEmitter(IEntity entity,
 String emitterResourceName)

Constructs a new EntityEmitter from a given emitter resource that remains at the location where it has been created.

Parameters:

entity - The IEntity to which this emitter is bound.

emitterResourceName - The name of the configuration for this emitter. If the Emitter has been added to the game resource file, it is loaded from there by name. Otherwise, the EmitterLoader will search the Resource folders for a file with the emitterResourceName.

EntityEmitter

public EntityEmitter(IEntity entity,
 EmitterAttributes emitterData,
 boolean dynamicLocation)

Constructs a new EntityEmitter with EmitterAttributes that follows an entity's location.

Parameters:

entity - The IEntity to which this emitter is bound.

emitterData - The EmitterAttributes object defining the emitter's behavior.

dynamicLocation - If true, the emitter follows the entity's location; if false, it remains at the location where it has been created.

EntityEmitter

public EntityEmitter(IEntity entity,
 EmitterAttributes emitterData)

Constructs a new EntityEmitter with EmitterAttributes that remains at the location where it has been created.

Parameters:

entity - The IEntity to which this emitter is bound.

emitterData - The EmitterAttributes object defining the emitter's behavior.

EntityEmitter

public EntityEmitter(IEntity entity)

Instantiates a new entity emitter that remains at the location where it has been created.

Parameters:

entity - The IEntity to which this emitter is bound.

EntityEmitter

public EntityEmitter(IEntity entity,
 boolean dynamicLocation)

Instantiates a new entity emitter.

Parameters:

entity - The IEntity to which this emitter is bound.

dynamicLocation - If true, the emitter follows the entity's location; if false, it remains at the location where it has been created.

Method Details

getEntity

public IEntity getEntity()

Get the IEntity to which this emitter is bound.

Returns:

The IEntity to which this emitter is bound.

hasDynamicLocation

public boolean hasDynamicLocation()

Check if the emitter has dynamic location tracking enabled. This determines whether this Emitter's location is updated along its entity's location.

Returns:

True if dynamic location is enabled, false otherwise.

setDynamicLocation

public void setDynamicLocation(boolean dynamicLocation)

Toggle dynamic location updates.

Parameters:

dynamicLocation - If true, the emitter follows its entity's location; if false, it remains at the location where it has been created.
