public static final DeferredRegister<Effect> EFFECTS = DeferredRegister.create(ForgeRegistries.POTIONS, Utils.MOD_ID); 

public static final RegistryObject<Effect> bl_instinct = EFFECTS.register（"bl_instinct"， BLInstinct：：new）;

 

 

why Inferred type 'I' for type parameter 'I' is not within its bound; should extend 'net.minecraft.potion.Effect'.

version 1.16.5

public class BLInstinct extends Effect {

    public BLInstinct(EffectType type, int hexColor){

          super(EffectType.NEUTRAL,0x993333);

           }

}

Show the BLInstinct class.

public class BLInstinct extends Effect {

    public BLInstinct(EffectType type, int hexColor){

          super(EffectType.NEUTRAL,0x993333);

           }

}

Look at which arguments the register method requires. Look at what you are providing it. Realize it does not match up, then fix it.

I don not know where does not match up.

Inferred type 'I' for type parameter 'I' is not within its bound; should extend 'net.minecraft.potion.Effect'

 

net.minecraftforge.registries.DeferredRegister<T extends IForgeRegistryEntry<T>> public <I extends T> net.minecraftforge.fml.RegistryObject<I> register(String name,
                                                                       java.util.function.Supplier<? extends I> sup

@SubscribeEvent

public static void onPotionRegistration（RegistryEvent.Register<Effect> event） {

event.getRegistry（）.registerAll（new BLInstinct（EffectType.NEUTRAL，0x993333）.addAttributeModifier（Attributes.MAX_HEALTH，"7107DE5E-7CE8-4030-940E-514C1F160890"，0.5f， AttributeModifier.Operation.MULTIPLY_TOTAL）.setRegistryName（Utils.MOD_ID， "bl_instinct"））;

}

This way no erro,but there is no effect in game.

register requires a supplier for the registry type (in your case Effect). You are giving it a constructor reference that does not match up with the functional interface Supplier. If you don't know what constructor/method references, lambdas and functional interfaces are - look them up. Or don't use them, you can implement the interface normally, too.

 

@SubscribeEvent
    public static void onPotionRegistration(RegistryEvent.Register<Effect> event) {
        event.getRegistry().registerAll(new BLInstinct(EffectType.NEUTRAL,0x993333).addAttributeModifier(Attributes.MAX_HEALTH,"7107DE5E-7CE8-4030-940E-514C1F160890",0.5f, AttributeModifier.Operation.MULTIPLY_TOTAL).setRegistryName(Utils.MOD_ID, "bl_instinct"));
    }

Is the event handler called? Check using the debugger.

Did you check that?

@Mod.EventBusSubscriber()
public class Registry {
    @SubscribeEvent
    public static void onPotionRegistration(RegistryEvent.Register<Effect> event) {
        event.getRegistry().registerAll(new BLInstinct(EffectType.NEUTRAL,0x993333).addAttributeModifier(Attributes.MAX_HEALTH,"7107DE5E-7CE8-4030-940E-514C1F160890",0.5f, AttributeModifier.Operation.MULTIPLY_TOTAL).setRegistryName(Utils.MOD_ID, "bl_instinct"));
    }
}

@Mod.EventBusSubscriber()

is this event handler?

Resolved .Thanks
