Constructor Details

InstanceManager

public InstanceManager(MaterialManager materialManager)

Method Details

createUpdateLimiter

protected DistanceUpdateLimiter createUpdateLimiter()

getObjectCount

public int getObjectCount()

Get the number of game objects that are currently being instanced.

Returns:

The object count.

canInstance

protected abstract boolean canInstance(T obj)

Is the given object capable of being instanced at all?

Returns:

false if on object cannot be instanced.

canCreateInstance

protected abstract boolean canCreateInstance(T obj)

Is the given object currently capable of being instanced?

This won't be the case for TEs or entities that are outside of loaded chunks.

Returns:

true if the object is currently capable of being instanced.

createRaw

@Nullable
protected abstract AbstractInstance createRaw(T obj)

tick

public void tick(TaskEngine taskEngine,
 double cameraX,
 double cameraY,
 double cameraZ)

Ticks the InstanceManager.

TickableInstances get ticked.
Queued updates are processed.

tickInstance

protected void tickInstance(int cX,
 int cY,
 int cZ,
 TickableInstance instance)

beginFrame

public void beginFrame(TaskEngine taskEngine,
 net.minecraft.client.Camera info)

updateInstance

protected void updateInstance(DynamicInstance dyn,
 float lookX,
 float lookY,
 float lookZ,
 int cX,
 int cY,
 int cZ)

add

public void add(T obj)

queueAdd

public void queueAdd(T obj)

queueUpdate

public void queueUpdate(T obj)

update

public void update(T obj)

Update the instance associated with an object.

By default this is the only hook an IInstance has to change its internal state. This is the lowest frequency update hook IInstance gets. For more frequent updates, see TickableInstance and DynamicInstance.

Parameters:

obj - the object to update.

remove

public void remove(T obj)

invalidate

public void invalidate()

getInstance

@Nullable
protected <I extends T> AbstractInstance getInstance(I obj)

processQueuedAdditions

protected void processQueuedAdditions()

processQueuedUpdates

protected void processQueuedUpdates()

addInternal

protected void addInternal(T obj)

removeInternal

protected void removeInternal(T obj,
 AbstractInstance instance)

createInternal

@Nullable
protected AbstractInstance createInternal(T obj)

onOriginShift

public void onOriginShift()

Specified by:

onOriginShift in interface InstancingEngine.OriginShiftListener

detachLightListeners

public void detachLightListeners()

queueAddAll

public void queueAddAll(Collection<? extends T> objects)
