How to ose non cubic model as mod-item?

[Drachenbauer]

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]

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)

A TESR is not necessary for rendering OBJs.

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

The forge:separate-perspective loader can be used to specify an entirely separate, embedded model for each perspective. See SeparatePerspectiveModel for some more info.

[Drachenbauer]

In blender my model has the size of 1m x 1m x 1m is this one block in minecraft?

if yes, then i have the right display-values now.

As i thested it, i got this error:

and it was stuck in a circle of crashing and reloading.

But i see nothing uppercase or other stuff after the folder "src"...

Post the full stacktrace, that is not at all how the resource location should look.

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

[diesieben07]

Your OBJ model has an invalid texture reference in it.

[Drachenbauer]

how do i write the texture reference right?

[diesieben07]

Just looked into it, the OBJ Loader even has some terrible Regex in it that attempts to parse absolute paths for textures and extract the resource domain and path. However for some reason in your OBJ file the backslashes are doubled, causing this to fail. Either make sure there are no absolute paths (should be in resource location format, like any other texture) or figure out why the software you are using incorrectly doubles the slashes.

[Drachenbauer]

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
Kd 0.800000 0.800000 0.800000
Ks 0.500000 0.500000 0.500000
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?

[diesieben07]

Are you talking about first or third person?

[Drachenbauer]

third person.

 

im first person the umbrella is already positioned correctly.

 

[diesieben07]

Not really possible without just taking over the whole player renderer, as far as I know.

[Drachenbauer]

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

Make two items.

Add an attribute modifier for ForgeMod.ENTITY_GRAVITY to your item. Look at how it is used in LivingEntity with the slow falling potion.

[Drachenbauer]

Now i added a set of closed umbrellas.

 

how do i now make the change on rightclick?

[Drachenbauer]

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?

[diesieben07]

Why on earth are you making your own attribute? Why are you reusing the modifier-UUID for the modifier used by the slow falling effect? Why are you naming your modifier the same?

 

You need to use ForgeMod.ENTITY_GRAVITY, not make your own attribute (nobody will care about it...). Also why would you do this in onUsingTick... Item already has a method that provides the attribute modifiers, don't apply them manually (look at swords for example).

[Drachenbauer]

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"
