How to ose non cubic model as mod-item?

Drachenbauer · December 21, 2020

Hello

i just cheated a pyramid-shaped umbrella in blender.

I also fitted it´s uv-mat to a minecraft-like texture.

Now i have the model as .blend and .obj-file and the texture as .png-file.

How can i use this umbrella as an item in a minecraft-mod?

Can i export it as .json?

.

Forge supports using obj models inside of minecraft. You can view the supported model loaders via ModelLoaderRegistry.

Drachenbauer · December 21, 2020

if i make an item-class for the umbrella, what must i put into it to use an .obi-modelloader insted of the normal json stuff?

And where in the ressource-folders must i place my obj-model and it´s textures?

Now i have got the basic mod setup with 16 items for different colored umbrellas registered.

And i have .obj-models and .png-textures for all 16 colors in the resource-folders.

how do i now load the models into the items?

And how can i control, how such an item looks in an inventory-slot, thrown on the ground, pinned in an item-frame and equipped in first and third person view?

There are some examples of Wavefront in in this tutorial project

see mbe21 (tileentity) and mbe81 (entity and item)

That is true, but if DrachenBauer wants this

then (s)he may need to use an ItemStackTileEntityRenderer.

mbe81 uses item json for wavefront rendering (no TER), eg

this circled again and again.

It seems like, it´s because of the absolute path in the .mtl-file if my model.

what kind of path must be used there?

I´m not sore, if the way, how it´s written in the json-files is compatible with .mtl...

Edited December 22, 2020 by Drachenbauer

Drachenbauer · December 22, 2020

how do i write the texture reference right?

Drachenbauer · December 22, 2020

Now i schanged my .mtl files to this:

# Blender MTL File: 'Umbrella.blend'
# Material Count: 1

newmtl Material
Ns 225.000000
Ka 1.000000 1.000000 1.000000

Ke 0.0 0.0 0.0
Ni 1.450000
d 1.000000
illum 2
map_Kd umbrellamod:model/black_umbrella

It´s the same path-style as for the boomerang in the examples mod.

But i still get sometimes this error but sometimes i can enter the game, but the umbrellas have the black and purple error-texture...

Edit:

now it works. maybe it just needed some refreshes...

How can i make the arm point horizontally forward, if holding an umbrella?

Drachenbauer · December 22, 2020

third person.

im first person the umbrella is already positioned correctly.

Drachenbauer · December 22, 2020

now i creadtd a model for closed umbrella, how can i make one click on the equipped umbrella opens it and another click closes it?

And how can i make slow falling and soft landing while the umbrella is open

Drachenbauer · December 22, 2020

Now i added a set of closed umbrellas.

how do i now make the change on rightclick?

Drachenbauer · December 22, 2020

for slow falling, i added

    private static final UUID SLOW_FALLING_ID = UUID.fromString("A5B6CF2A-2F7C-31EF-9022-7C3E7D5E6ABA");
    private static final AttributeModifier SLOW_FALLING = new AttributeModifier(SLOW_FALLING_ID, "Slow falling acceleration reduction", -0.07, AttributeModifier.Operation.ADDITION).setSaved(false);
    public static final net.minecraft.entity.ai.attributes.IAttribute ENTITY_GRAVITY = new net.minecraft.entity.ai.attributes.RangedAttribute(null, "forge.entity_gravity", 0.08D, -8.0D, 8.0D).setShouldWatch(true);

above the constructor in the UmbrellaItem class and

        IAttributeInstance gravity = player.getAttribute(ENTITY_GRAVITY);
        gravity.applyModifier(SLOW_FALLING);
        player.fallDistance = 0.0F;

in "onUsingTick".

but falling is as fast as normal and i see the collison-particles on landing.

Must i place the lines in the seccond code-snippet into another method?

Drachenbauer · December 23, 2020

i thaught, this is the way to add a modifyer...

You told me to look in Entity living.

And i thaught, this is the way, it is used there.

in the sword i founf this:

public Multimap<String, AttributeModifier> getAttributeModifiers(EquipmentSlotType equipmentSlot) {
      Multimap<String, AttributeModifier> multimap = super.getAttributeModifiers(equipmentSlot);
      if (equipmentSlot == EquipmentSlotType.MAINHAND) {
         multimap.put(SharedMonsterAttributes.ATTACK_DAMAGE.getName(), new AttributeModifier(ATTACK_DAMAGE_MODIFIER, "Weapon modifier", (double)this.attackDamage, AttributeModifier.Operation.ADDITION));
         multimap.put(SharedMonsterAttributes.ATTACK_SPEED.getName(), new AttributeModifier(ATTACK_SPEED_MODIFIER, "Weapon modifier", (double)this.attackSpeed, AttributeModifier.Operation.ADDITION));
      }

      return multimap;
   }

but in "SharedMonsterAttributes" i cannot find the "ENTITY_GRAVITY" attribute.

So how els can i put this attribute there?

If i replace "SharedMonsterAttributes" with "ForgeMod", it also cannot find "ENTITY_GRAVITY" in there...

The only appearens of "ENTITY_GRAVITY", that i can find, is in "LivingEntity"

Edited December 23, 2020 by Drachenbauer

Drachenbauer · December 23, 2020

if i open this ForgeMod Class fron the Reference Libraries in my ide it does not contain theese lines, that are highlighted in your link.

Maybe its added there since 1.16...

Is it anywhere else in 1.15?

Edited December 23, 2020 by Drachenbauer

Drachenbauer · December 23, 2020

I try to use this:

public Multimap<String, AttributeModifier> getAttributeModifiers(EquipmentSlotType equipmentSlot)
    {
        Multimap<String, AttributeModifier> multimap = super.getAttributeModifiers(equipmentSlot);
        
        if (equipmentSlot == EquipmentSlotType.MAINHAND)
        {
            multimap.put(LivingEntity.ENTITY_GRAVITY.getName(), new AttributeModifier(LivingEntity.SLOW_FALLING_ID, "Slow falling acceleration reduction", -0.07, AttributeModifier.Operation.ADDITION).setSaved(false));
        }
        
        return multimap;
    }

But i still have a problem with this line:

multimap.put(LivingEntity.ENTITY_GRAVITY.getName(), new AttributeModifier(LivingEntity.SLOW_FALLING_ID, "Slow falling acceleration reduction", -0.07, AttributeModifier.Operation.ADDITION).setSaved(false));

i cannot use LivingEntity.SLOW_FALLING_ID, because it´s private

So i tryed this:

multimap.put(LivingEntity.ENTITY_GRAVITY.getName(), LivingEntity.SLOW_FALLING);

But LivingEntity.SLOW_FALLING is also private.

what is the right setup for this line?

Drachenbauer · December 23, 2020

How do i make my own modifyer?

I want it exactly the same as the existing slow falling effect.

Some posts ago you told me, copying the stuff from LivingEntity is not the right way.

Edited December 23, 2020 by Drachenbauer

Drachenbauer · December 23, 2020

are there any rules for this id?

Drachenbauer · December 23, 2020

In the existing one letters where uppercase, in the one from the page, letters are lowercase.

Does this matter?

And i cannot find infos about what to use instead of "getAttributeModifiers", that is deprecated

Edited December 23, 2020 by Drachenbauer

Drachenbauer · December 23, 2020

I cannot find a replacement for the deprecated "getAttributeModifiers".

i see nothing else about attributes there.

Drachenbauer · December 23, 2020

i added an itemstack-argument to the method and it´s super-call and now the warning is gone.

and the slow falling works now.

Drachenbauer · December 26, 2020

https://www.youtube.com/watch?v=6te-IdUIBdY

here he hoints his arm up while holding an umbrella.at the end of the video.

but there in no link to the mod with the umbrella...

I notived, i fall slower with the umbrella, bot still get a tiny little bit of damage on landing.

How to remove the fall damage compleetely, if holding that item?

Edit: i canceled the LivingFallEvent, if holding the umbrella.

Now i can jump from as high as i want with the umbrella without being damaged.

Edited December 27, 2020 by Drachenbauer

Drachenbauer · January 8, 2021

I noticed, that i can jump higher, if holding this umbrella.

Than i saw a video of someone, who made a tower of scaffolding, placed a cage of scaffolfing ontop and filled it with chckens.

Then he removed the bottom scaffolding and the chickens fell down slowly and took no damage at landing on the ground.

how can i attach this exact behavior to my umbrella?

In the ChickenEntitx-Class i find just this:

    public boolean onLivingFall(float distance, float damageMultiplier)
    {
        return false;
    }

But nothing about the falling-speed.
