Hello, 

I'm trying to create a tnt but I can't manage to register the EntityRenderer.

Here is the error

C:\Users\hadri\Desktop\futurcraft\src\main\java\fr\steakmans\futurcraft\utils\ClientModEvents.java:24: error: incompatible types: inference variable T has incompatible bounds
        e.registerEntityRenderer(ModEntities.PRIMED_INCENDIARY_TNT.get(), IncendiaryTntRenderer::new);
                                ^
    equality constraints: IncendiaryPrimedTnt
    lower bounds: Entity
  where T is a type-variable:
    T extends Entity declared in method <T>registerEntityRenderer(EntityType<? extends T>,EntityRendererProvider<T>)

And here is my ClientModEvents:

package fr.steakmans.futurcraft.utils;

import fr.steakmans.futurcraft.Main;
import fr.steakmans.futurcraft.entity.ModEntities;
import fr.steakmans.futurcraft.entity.explosion.IncendiaryPrimedTnt;
import fr.steakmans.futurcraft.entity.explosion.renderer.IncendiaryTntRenderer;
import net.minecraft.client.renderer.entity.EntityRenderers;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.client.event.EntityRenderersEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent;

@Mod.EventBusSubscriber(modid = Main.MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT)
public class ClientModEvents {

    @SubscribeEvent
    public void clientSetup(FMLClientSetupEvent e) {

    }

    @SubscribeEvent
    public void registerRenderers(EntityRenderersEvent.RegisterRenderers e) {
        e.registerEntityRenderer(ModEntities.PRIMED_INCENDIARY_TNT.get(), IncendiaryTntRenderer::new);
    }

}

And lastly, here is my ModEntities:
 

package fr.steakmans.futurcraft.entity;

import fr.steakmans.futurcraft.Main;
import fr.steakmans.futurcraft.entity.explosion.IncendiaryPrimedTnt;
import net.minecraft.resources.ResourceLocation;
import net.minecraft.world.entity.Entity;
import net.minecraft.world.entity.EntityType;
import net.minecraft.world.entity.MobCategory;
import net.minecraft.world.entity.item.PrimedTnt;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;
import net.minecraftforge.registries.RegistryObject;

public class ModEntities {

    public static final DeferredRegister<EntityType<?>> ENTITIES = DeferredRegister.create(ForgeRegistries.ENTITIES, Main.MODID);

    public static final RegistryObject<EntityType<Entity>> PRIMED_INCENDIARY_TNT = ENTITIES.register("primed_incendiary_tnt", () -> 	 EntityType.Builder.of(IncendiaryPrimedTnt::new, MobCategory.MISC).build(new ResourceLocation(Main.MODID, "incendiary_primed_tnt").toString()));

}

 

1 hour ago, steakmans said:

RegistryObject<EntityType<Entity>> PRIMED_INCENDIARY_TNT

you need to specify the EntityType to the Entity you register (IncendiaryPrimedTnt)

When I do  that there is another error:
 

C:\Users\hadri\Desktop\futurcraft\src\main\java\fr\steakmans\futurcraft\entity\ModEntities.java:18: error: incompatible types: inference variable I has incompatible bounds
    public static final RegistryObject<EntityType<IncendiaryPrimedTnt>> PRIMED_INCENDIARY_TNT = ENTITIES.register("primed_incendiary_tnt", () -> EntityType.Builder.of(IncendiaryPrimedTnt::new, MobCategory.MISC).build(new ResourceLocation(Main.MODID, "incendiary_primed_tnt").toString()));
                                                                                                                 ^
    equality constraints: EntityType<IncendiaryPrimedTnt>
    lower bounds: EntityType<Entity>
  where I is a type-variable:
    I extends EntityType<?> declared in method <I>register(String,Supplier<? extends I>)

 

you also need to specify the EntityType.Builder

I'm not sure how to do that, could you tell me how to please.

unfortunately I'm not at my pc, but it should EntityType.Builder<YourEntity>.of or EntityType.Builder.<YourEntity>of

The second one worked but nom I have (again) another error:

your EventHandler for the registery of the EntityRenderer is not called,
since ClientModEvents#registerRenderers must be static if you use @EventBusSubscriber

Thank you, evrything works fine now.
