Where do you register/input Throwable Entity's texture?

[SevenDeadly]

Title says it all. If I make an item that fires an entity (Let's say an exploding baseball as an example ) on right click, it shoots an invisible entity (I am certain it is shooting it, because onImpact it has the properties of my Throwable Entity). Since they changed the way you used to register the texture for EntityThrowable Entities, how do you do it now?

 

 

[coolAlias]

That depends on how you set the texture before. I always used an Item for the projectile and just used that Item texture for the Entity. For example, if I have a cannon I'll make an Item cannonBall.

 

You can either register the texture in the class with registerIcons or, if you don't want to make a class, use setTextureName("texture_name") - that's the updated name for func_111somethingsometing_d from before, so you still need to prefix the texture name with your mod id + ":"

 

When you register your throwable entity renderer, if it's set up similar to RenderSnowball, you just pass in the Item and it will use the correct texture.

[chimera27]

I just do it in my Render(projectilename) class and register it in my clientproxy, here's an example...

(Replace ProjectileName with your projectiles name)

EntityRegistry.registerGlobalEntityID(EntityIceBolt.class, "ProjectileName",
			EntityRegistry.findGlobalUniqueEntityId());
RenderingRegistry.registerEntityRenderingHandler(EntityProjectileName.class,
			new RenderProjectileName());

Just add this under your load method in your main too:

EntityRegistry.registerModEntity(EntityProjectileName.class, "WaveBolt", CUSTOM ENTITY ID,
			this, 64, 1, true);

Finally make a class called RenderProjectileName and find some vanilla projectile that you want to change the sprite of (I would do an arrow because its really just 2 flat rectangles, not shaped like an arrow) and use

 

private static final ResourceLocation texture = new ResourceLocation("MODID","textures/entities/entityprojectilenameinalllowercase.png");

@Override
protected ResourceLocation getEntityTexture(Entity entity) {
	return texture;
}

Also, make sure the .png file name is completely lowercase, both in the code and the file itself or it won't work.

Every time I throw the entity now, I still have an invisible texture. However, I also get this error:

Entity Registration (Method in common proxy, called from my load method in my Main Class though)

	public void registerEntities() {
	EntityRegistry.registerModEntity(EntityBall.class, "Ball", 257, MyMod.instance, 64, 1, true);

Rendering Registration and other Entity Registration (Of course this is in the client proxy method registerRenderers and registerEntities:))

Did you put the method I said in your main? Because I had this exact problem and that fixed it for me..

[SevenDeadly]

If you are talking about this:

EntityRegistry.registerModEntity(EntityProjectileName.class, "WaveBolt", CUSTOM ENTITY ID,
			this, 64, 1, true);

Then yes and no. It's in another class to keep my organization, but the method containing it is called from the load method. So it's essentially like having it in the load method of my main.

Hi

 

Your crash log suggests to me that the server is trying to invoke a NetworkModHandler which hasn't been defined (is NULL) for your custom entity.  Normally Forge provides a default one for your entities automatically, I think.

FMLNetworkHandler.getEntitySpawningPacket is the place where it retrieves the appropriate NetworkModHandler.

 

After that I get lost...  but I suspect it's something to do with your entity being registered differently on the client and the server.  The crash occurs when the server tries to create a packet to tell the clients about the new entity.  It's nothing to do with the rendering code.

 

Not much help, sorry!  I'm still learning this myself.

You mentioned this is in your CommonProxy? I think you should only register entities in ClientProxy, which could be the cause of your null network mod handler. At least, I only register mine in ClientProxy and it works for me on the Eclipse server. I can't claim any expertise in this particular area other than that.

 

EDIT: This is wrong. Entities should be registered on both sides, so do it from main mod load method or somewhere similar. Thanks Goto again for the correction.

[GotoLink]

Read the tutorials in the wiki please.

Choose one the EntityRegistry method and stick to it. And register on both sides, obviously.

[SevenDeadly]

There's no tutorial on the wiki on ThrowableEntities, and ThrowableEntities are obviously different than normal Entities. <.<

[GotoLink]

EntityThrowable extends Entity.

Basic Java: Throwable entities are entities.

[coolAlias]

Read the tutorials in the wiki please.

EDIT: Goto was right, of course. I fired up the Eclipse server and tried my custom entity there, didn't render. Moving 'registerModEntity' to the load method of my main mod class resolved the issue. Too bad that's not mentioned in the Forge wiki tutorial, unless there's another one that deals with registering entities besides the SpaceMarine blasterRifle one. If there is, it's not easy to find.

 

Thanks for clearing that up Goto. I've been looking through your mods on github and I can't seem to find where you register your entities... I only see lines like the following:

RenderingRegistry.registerEntityRenderingHandler(EntitySteamBoat.class, new RenderSteamBoat());

I know that's in ClientProxy only, but do you register the EntitySteamBoat? Where? I don't see it in CommonProxy or the main mod class.

 

Thanks again. It's nice to have someone who really understands the code - like I said, the method I used above seems to work fine, and that's the way it says to do it in the Blaster Rifle tutorial on the wiki, but what you say makes sense about needing to register on both sides.

EntitySteamBoat is registered below //Boat comment in Pchan3Mods class ("main" mod class).

I tend to register things in the "main" mod class, but any common class would do, actually.

 

I have looked at most generic tutorials so those are fine, but any other i won't comment on.

I think it is better to work things on your own, eventually taking examples from similar mods.

But do not take other mods as absolute reference material. Anyone can make mistakes.
