[Solved] [1.16.5] How to make a chunk capability


Recommended Posts

Hi, I'm trying to save some additional data to chunks, and have figured out that Capabilities are probably the way to go. After looking around the internet for a bit I think I got the gist and I set to coding. However, the AttachCapabilitiesEvent#addCapability() method seems to require an ICapabilityProvider, which I don't remember seeing anything on. Here's what I've got so far:


IRift class:

public interface IRift {
	boolean isRift();
	float getRiftActivityPercent();
	void setRiftActivityPercent(float riftActivityPercent);
	void makeRift();
	void closeRift();
	void riftEvent();


RiftStorage class:

public class RiftStorage implements Capability.IStorage<IRift> {

	public INBT writeNBT(Capability<IRift> capability, IRift instance, Direction side) {
		CompoundNBT nbt = new CompoundNBT();
		if(instance.isRift()) {
			nbt.putBoolean("isRift", instance.isRift());
			nbt.putFloat("riftActivityPercent", instance.getRiftActivityPercent());
		return nbt;

	public void readNBT(Capability<IRift> capability, IRift instance, Direction side, INBT nbt) {
		CompoundNBT cnbt = ((CompoundNBT)nbt);
		if(cnbt.getBoolean("isRift")) {


RiftCapability class:

public class RiftCapability implements IRift {
	private boolean isRift = false;
	private float riftActivityPercent = 0.0f;

	public boolean isRift() {
		return isRift;

	public float getRiftActivityPercent() {
		return riftActivityPercent;

	public void setRiftActivityPercent(float riftActivityPercent) {
		if(riftActivityPercent < 0 || riftActivityPercent > 1) throw new IndexOutOfBoundsException("Rift Activity Percent cannot be less than 0 or greater than 1!");
		else this.riftActivityPercent = riftActivityPercent;

	public void makeRift() {
		this.isRift = true;

	public void closeRift() {
		this.isRift = false;

	public void riftEvent() {
		//TODO: Fire a rift event.


Advice much appreciated. Thanks :)

I'm probably more excited than I should be for something so realistically minor...
