[1.16.2] Render Layer not Working

[HeyImAmethyst]

I added and item the allows the player to fly when if it is in the player's inventory and I want to have wings appear on the player when ever the item is in the inventory, Similar to how extra utilities does it with the angel rings it adds. I learned that I can to this with render layers. I followed the class structure for the elytra render layer and I saw that online I can add the layer in with an event but it is not rendering on my player. I'm not even getting any broken texture letting me know that at least my model is on the player.

This is my layer class for my wings:

This is the event I am using:

Why are your ModelRenderers declared inside the model class constructor? Also you commented out the "render" function, where the rendering of your model actually happens

This means you are adding a new layer to the renderer every single frame for every single player that is rendered. This is not a good idea.

 

Oh ok! Is there a better way I can add the layer to the player?

When I was making custom witch hat models, I was having problems with the model not properly following the player head. I learned that I needed to keep them local so that there weren't issues like that and I have tested it with them being global vs them being local and it makes a difference. For the render part I think I was following a tutorial on out to import custom models and the render part was commented out. I'll uncomment the method though in case it makes a difference.

 

Edit: Here is the website I used to help me make my witch hats

Didn't see this line, my bad:

bipedBody.addChild(Wings);
	

Are you sure your event handler is actually getting called?

I put my event in the same place as my flying event so I assumed it was working

Do it once at startup.

 

I tried putting this in my main mod class just to see if I can get it to work:
 

Minecraft mc = Minecraft.getInstance();
EntityRendererManager manager = mc.getRenderManager();
manager.getSkinMap().get("default").addLayer(new LayerWings<AbstractClientPlayerEntity, PlayerModel<AbstractClientPlayerEntity>>(WingsRenderer.instance));
manager.getSkinMap().get("slim").addLayer(new LayerWings<AbstractClientPlayerEntity, PlayerModel<AbstractClientPlayerEntity>>(WingsRenderer.instance));
        

 

But I'm getting this error:

 

Failure message: Magi Witch Hats (mwh) has failed to load correctly
		java.lang.NullPointerException: Cannot invoke "net.minecraft.client.renderer.entity.EntityRendererManager.getSkinMap()" because "manager" is null

 

I guess something is working since it gave me this crash but I don't understand why manager is returning null.

Doing it in your mod constructor is a) too early and b) will crash on servers (the server has no idea what the Minecraft class is).

Use FMLClientSetupEvent and also enqueueWork, because the layer list is not threadsafe.

 

Thanks! I was able to get it to work. The render is funky but I'll figure it out. At least something is on my player's back XD. But if I wanted other players to see the wings if I am on a server, would I need to do something similar in a server event similar to FMLClientSetupEvent or is this a whole different process completely?
