[1.15.2] Issues With Armorstands and Custom Armor

[TonyGamer]

I added custom armor with a custom model to a mod that I am working on, and I have gotten the model to render correctly on the player, but when I attempt to put the armor on an armorstand, it animates as if it is on a player. I have an idea of why this might be happening, but I have no clue how to fix it. Here is the model file and the class of one of the armor pieces:

Some notes about these files: the model file was mostly generated from blockbench, with some modifications made to allow it to work as an armor model. The armor item getArmorModel function was found from another post somewhere else (I don't remember where and the post was hard to find in the first place), as well as some modifications to get it to render correctly in the current versions, and also my attempt at caching the model (I don't know if it is a good idea to cache it or if I even implemented it correctly).

This is not how one does armor modeling. First and foremost, you cache the model in the item which will crash on any dedicated server. Second, of course it will be synchronous, it matches the player model to model. Third, it's not even a biped model.

 

I've honestly written this out quite a lot, so apologies for linking my own material, but take a read at this because I'm just tired of writing this over and over.

Oh... I saw that earlier but I only skimmed through it and completely overlooked that section... I will try that and see what happens, thanks.

EDIT: Also it wasn't set as a biped model because I had exported it from block bench and forgot to change it to a biped model.

Hello !
As for the original problem take a look at this : https://github.com/MinecraftForge/MinecraftForge/issues/2508#issuecomment-287781387
You'll get a better grasp of what's going on.
Basically, your "setRotationsAngles" functions has to act differently whether the entity is a player or an armor_stand.
Here, your "setRotationsAngles" will always act as if the armor_stand was a player, therefore you have to test in "setRotationAngles" if the entity is an armor_stand, if it is then you have to copy the hardcoded values from ModelArmorStand::setRotationAngles and apply them to your armor, if it isn't an ArmorStandEntity, just call the normal behaviour off "setRotationAngles" with super
When you think you've understood what's going on, take a look at how Botania fixes this : https://github.com/Vazkii/Botania/blob/1.14-final/src/main/java/vazkii/botania/client/model/armor/ModelArmor.java
When you have this kind of problems always try to look how other mods do it
