[TUTORIAL] Making a flying armor 2022.x - Forge 1.18.2 - Look at the comments for updates up to 2023.x 1.20.1

Is there any way to make it get powered when you press spacebar instead of using rockets or another extra item? 

This looks super cool for the mod I have in mind, but I need to ask 2 questions first:

1, does this work in the newest version of MCreator?

2, would it be possible to give this infinite boost/momentum, (like when you use a firework),?

I am in mcreator 2023.3 fabric generator, can you make one for geckolib armor in FABRIC?

This is my first time trying to change code, and i'm not an english speaker, maybe i'm commiting a dumb mistake. Well, actually i'm in the version of 2023.2 - 1.19.2, and when i'm trying to run it breaks, and then in the log this appears

error: cannot find symbol if (!entity.level().isClientSide) {
^
symbol: method level()
location: variable entity of type LivingEntity

When I did it, it didn't work properly, so I solved it by removing the code that reduces durability during flight.
I think I need to make that part as a procedure :)

Changes made in 2024.4 version have also been reflected.

Thank you for the good tutorial.

Hello, I know the topic is old but I want to ask anyway to see if someone can help me.

I'm trying to get this to work on the most recent (at this time) version of MCreator, 2025.1 EAP 05718 for Minecraft NeoForge 1.21.4.

I have armor, just the breastplate, and I want to fly with this code. Copying the code (latest version from answers) gives me this error:

error: The method does not override or implement a method of a supertype.

I googled it and the error comes from using @Override, when I remove the two lines where it says @Override, the mod compiles without errors but it doesn't work in the game, the armor doesn't fly.

So, I have to remove @Override (because the ArmorItem superclass doesn't contain the method I'm trying to call) but if I do, the code doesn't work.

What do I have to do then?

As it became 1.21.4 version, the function seems to have moved to another place.

In version 1.21.1, you could have enabled that feature
I don't see it in version 1.21.4...

I need to check the API for version 1.21.4 of neforge
The problem is, I don't know how to check ;)

I tried using your code but I get error:

error: incompatible types: EquipmentSlot is not a functional interface 

stack.hurtAndBreak(0, entity, e -> e.broadcastBreakEvent(EquipmentSlot.CHEST));

@Override
    public boolean canElytraFly(ItemStack stack, LivingEntity entity) {
        return true;
    }

    @Override
    public boolean elytraFlightTick(ItemStack stack, LivingEntity entity, int flightTicks)
    {
        if (!entity.level().isClientSide && (flightTicks + 1) % 20 == 0) { //HERE IS THE .level THAT CHANGED TO .level() 
            //set stack.hurtAndBreak from 1 (default value - breakable) to 0 (unbreakable)
            stack.hurtAndBreak(0, entity, e -> e.broadcastBreakEvent(EquipmentSlot.CHEST));

        }
        return true;
    }

    protected boolean onGround;
    public void setOnGround(boolean p_20181_) {
        this.onGround = p_20181_;
    }

    public boolean isOnGround() {
        return this.onGround;
    }

I am using newest MCreator neoforge 1.21.1

The line will cause a build error in 2024.4 version.
It's a part that subtracts the durability, and this part can be implemented sufficiently as a trigger, so I recommend removing it.

Thanks

So i asked on the discord server of neoforge about that, they told that there's data component for adding elytra behaviour to an item.
The data component it's called glider.
I only could find this about adding data components to items, but I really don't understand how I have to do it and how I would have to modify the code that we have to make it work :1

Set up the procedure.

If you put the code in the code snippet, it works the same as Elitra.
However, I think we need to take care of the conditions.

[FallFlying Start]

if (entity instanceof Player _player) { _player.startFallFlying(); }

[FallFlying Stop]

if (entity instanceof Player _player) { _player.stopFallFlying(); }

Even if you don't change Elitra to 'true', the ability to accelerate with firecrackers is automatically activated, and the landing works the same as Elitra.
