[1.8.9] [SOLVED] Registering a new mob entity?

[DragonessAtHeart]

Hello everyone.

 

I'm pretty new to modding with Forge and forums and I apologize if this is in the wrong place or anything.

 

I'm pulling my hair out trying to figure out how to properly register and render a new entity in 1.8.9.

 

I have no idea what the IRenderFactory is or how to use it and I'm not even really sure rendering is my only problem.

I have the entity class and the model class for the mob and a render class but I'm hitting a wall trying to find examples of how to do it properly with the new update. Everyone is just saying "use the registerEntityRenderingHandler" thing but I really have no idea specifically how to do this. This is my first mod.

 

Could someone out there help me out? Thank you!!

 

I have seen this topic:  [1.8]Error Spawning in Entities, and this one,  [1.8.9] Entity rendering registering recently changed?, but I need more information about how to actually do what they talk about.

 

Also I'm not sure how to link a post. >> Sorry....

 

Please be gentle...

It's literally an interface to return a RenderEntity instance. Just allows the rendermanager to be passed to each entity renderer

[DragonessAtHeart]

Could you maybe give an example of how to use it?

[Choonster]

If you're targeting Java 6/7, just create an anonymous class that implements

IRenderFactory

and overrides

createRenderFor

to return a new instance of the your

Render

class.

 

If you're targeting Java 8, you can use a method reference to pass your

Render

class's constructor (

RenderMyEntity::new

) as an

IRenderFactory

instead.

Well I am pretty lazy with my registry so I literally dump all my classes through a Proxy method:

@Override
public void sidedEntityRegistry(Class<? extends Entity> c){
	try {
		final Class cc = (Class<? extends Render>) c.getClassLoader().loadClass("rankshank/pikmine/client/render/entity/" + c.getName().substring(c.getName().lastIndexOf("Entity")).replace("Entity", "Render"));
		RenderingRegistry.registerEntityRenderingHandler(c, new IRenderFactory<Entity>(){
                            @Override 
                            public Render createRenderFor(RenderManager rm) {
                                try {
                                    return (Render) cc.getConstructor(RenderManager.class).newInstance(rm);
                                } catch(Exception e){
                                      e.printStackTrace();
                                return null;}}});
	    } catch (Exception e) {
		e.printStackTrace();
	    }
}

Works a treat though since I follow a set naming standard. You can just do direct class references if iteration is too 'scary'

I am trying to target Java 8, but thank you for mentioning both.

 

"you can use a method reference to pass your Render class's constructor (RenderMyEntity::new) as an IRenderFactory instead."

 

The render class here we are talking about is the new mob's render class?

 

I feel like I want to do something like this,

registerEntityRenderingHandler(EntityNewMob.class, IRenderFactory (RenderNewMob::new));

but that isn't how you do it.

 

Also oh my goodness RANKSHANK there is so much going on there!

 

I'll have to study that code to see if I can't figure out what is going on.

 

Can you tell me where I need to start researching to figure it out or try to explain it a bit more?

 

If you don't feel like it, that's cool. I can probably figure it out eventually.

It's actually not too bad, the error handling just gunks it up a bit

 

Basically I'm working off the principle that all of my renderers are in rankshank/pikmine/client/render/entity/ and follow the naming format Render{EntityName}.class, their corresponding entity classes just need to follow the naming format Entity{EntityName}.class.

 

Using the known package and transforming the Entity prefix to the Render prefix, I then have a string handle for my Render class.

 

Then using that string handle I query the ClassLoader for the class object which I then create and instance of it using the Render(RenderManager) constructor, which is a consistent constructor throughout my render classes.

 

I then use that as the return value of my RenderFactory which registers the renderer.

 

It all runs off the expectation that I'll continue to follow the same format. I may have to switch to using hard coded strings so that I can subpackage my render folder.

I feel like I want to do something like this,

registerEntityRenderingHandler(EntityNewMob.class, IRenderFactory (RenderNewMob::new));

but that isn't how you do it.

 

The parentheses weren't part of the code. Just pass the method reference itself as the

IRenderFactory

argument, you don't need to explicitly cast to or specify that it's an

IRenderFactory

.

 

registerEntityRenderingHandler(EntityNewMob.class, RenderNewMob::new);

[DragonessAtHeart]

Okay I tried that but the compiler is mad at the RenderNewMob::new part.

 

I just give it the render class I made for the mob correct? No?

[DragonessAtHeart]

Okay, it's becoming clear I am confused about both registering the entity first, and then rendering the entity.

 

I think the bigger problem I'm having is with rendering it.

 

 

 

[DragonessAtHeart]

I'm sorry. I didn't mention that I had tried that already unsuccessfully.

 

I am now doing this:

registerEntityRenderingHandler(EntityGiantLizard.class, RenderGiantLizard::new);

 

Which tells me that the registerEntityRenderingHandler method is not defined for my client proxy.

 

I've imported

import net.minecraft.client.Minecraft;

import net.minecraft.client.renderer.entity.RenderManager;

import net.minecraftforge.fml.client.registry.RenderingRegistry;

import net.minecraftforge.fml.common.Mod.Instance;

import net.minecraftforge.fml.common.event.FMLInitializationEvent;

import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;

import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;

import net.minecraftforge.fml.common.registry.EntityRegistry;

import net.minecraftforge.fml.common.registry.EntityRegistry.EntityRegistration;

import net.minecraftforge.fml.common.registry.LanguageRegistry;

import net.minecraftforge.fml.relauncher.Side;

 

import net.minecraftforge.fml.client.registry.IRenderFactory;

import net.minecraftforge.fml.client.registry.ClientRegistry;

import com.dragonessatheart.firstmod.*;

 

So unless I'm forgetting something, I'm not sure what to do.

 

When I try this:

RenderingRegistry.registerEntityRenderingHandler(EntityGiantLizard.class, RenderGiantLizard::new);

 

It says:

The method registerEntityRenderingHandler(Class<? extends Entity>, Render<? extends Entity>) in the type RenderingRegistry is not applicable for the arguments (Class<EntityGiantLizard>, RenderGiantLizard::new)

 

Which I honestly don't know how to decipher.

 

Thank you!

The version of forge is: forge-1.8.9-11.15.1.1722, at least that's what it says on the changelog txt name.

 

I know it's at least 1.8.9. The recommended one.

 

RenderGiantLizard is here.

Thank you so much!

I forgot to mention that I recently updated forge, so some of the code is still obfuscated, but I feel like that wouldn't effect anything right?

[Choonster]

For a method reference to be used as an interface, the method must have the same signature as the interface's method.

 

IRenderFactory#createRenderFor

takes a single

RenderManager

argument and returns a

Render

, your method must do the same. Constructors implicitly return an instance of their class, so you just need to match the arguments.

 

You don't need to create your own

renderManager

field,

Render#renderManager

already exists with protected access.

[crackedEgg]

Here is one example of how to do this. https://github.com/m1k3s/parachute/blob/master/parachute/client/ParachuteClientProxy.java#L46

There are other projects in that github for mobs. They target java 7 though. The parachute was updated to target java 8.

[DragonessAtHeart]

The example on github is ridiculously helpful.

 

Thank you so much!
