How do i hide not needed Biped-Bodyparts?

[Drachenbauer]

Hello

I´m creating a Player-model as a classic Angry Birds-character.

I want the whoole visible bird act as the head (rotating with mouse-movement) and two invisible cubes as arms (to use armpose animations for holded items).

It should look like the Angry birds use objects wich some telecinetic powers in their cartoon-series (objects hover next to their body and can be moved by the bird.).

I made it extend BipedModel, because this class holds alot of stuff, that a player-character needs:

package drachenbauer32.angrybirdsmod.entities.models;

    {
        if (this.field_228286_w_ == null)
        {
            this.field_228286_w_ = Lists.newArrayList();
        }
        
        this.field_228286_w_.add(p_accept_1_);
    }
}

But i have some questions:

 

1.

How do i prevent it from rendering the body and legs parts from BipedModel?

 

2.

Does it render my bodyparts instead of the ones from BipedModel?

 

3.

The whoole body of this bird has the same size as the head of the common player-model, but sit´s directly on the ground.

How do i make the helmet from armour appear in this new lower position (i think, the other armour pieces don´t appear, because i didn´t place them here)?

1.- You have to register the event in a class like this 

public class YourEventClassEventHandler {
    @SubscribeEvent
    public static void negateFallDamage(LivingFallEvent event) {

        if (event.getEntityLiving() instanceof PlayerEntity) {


            PlayerEntity playerEntity = (PlayerEntity) event.getEntityLiving();

            if (playerEntity.getItemStackFromSlot(EquipmentSlotType.CHEST).getItem() == ItemHolder.BATMAN_CHEST) {
                event.setCanceled(true);
            }

        }

    }


    @SubscribeEvent
    public static void onRenderPlayerPre(RenderPlayerEvent.Pre event) {
        PlayerEntity player = (PlayerEntity) event.getEntity();

        if (player.isElytraFlying() && player.getItemStackFromSlot(EquipmentSlotType.CHEST).getItem() == ItemHolder.BATMAN_CHEST) {



            event.getRenderer().getEntityModel().bipedRightArm.showModel = false;
            event.getRenderer().getEntityModel().bipedRightArmwear.showModel = true; //70 varillas 45 de cemento
            event.getRenderer().getEntityModel().bipedLeftArm.showModel = false;
            event.getRenderer().getEntityModel().bipedLeftArmwear.showModel = true;
            event.getRenderer().getEntityModel().bipedBody.showModel = false;




        }

    }

    @SubscribeEvent
    public static void onRenderPlayerPost(RenderPlayerEvent.Post event) {
        PlayerEntity player = event.getPlayer();
        
    }
}

as you can see the onRenderPlayerPre method handles the render of the player, there you can get the model and hide the body parts you want, then you can register the events in the constructor of your mod like this:

MinecraftForge.EVENT_BUS.register(YourEventClassHandler.class);
