Trying to make a boomerang-like ThrowableEntity with a Model? [1.7.10]

[Arekkuusu]

Hello, Im trying to make an Entity that extends EntityThrowable or something. I made a bounceBack() method that reverts the Entity Velocity. The error is that Entity only renders when you extend EntitySnowball (And it does not use the Model), if you extend EntitySnowball the getGravityVelocity() method does not work and the model is a generic snowball...

 

This is the Entity V1:

 

 

package arekkuusu.grimoireOfAlice.entity;

import cpw.mods.fml.common.registry.IThrowableEntity;
import net.minecraft.entity.Entity;
import net.minecraft.entity.projectile.EntitySnowball;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.util.Vec3;
import net.minecraft.world.World;

public class EntityEllyScythe extends EntitySnowball implements IThrowableEntity{

protected double velX, velY, velZ;
protected Entity shootingEntity;
protected int ticksInAir;
protected int knockBack;
protected double damage;
protected boolean isCritical;

public EntityEllyScythe(World p_i1773_1_, Vec3 position, Vec3 acceleration) { 
	super(p_i1773_1_, position.xCoord, position.yCoord, position.zCoord);
	velX = acceleration.xCoord/2;
	velY = acceleration.yCoord/2;
	velZ = acceleration.zCoord/2;
	setVelocity(velX, velY, velZ);
	isCritical = false;
	ticksInAir = 0;
}

@Override
public void setThrower(Entity entity) {
	shootingEntity = entity;
}

@Override
public void onUpdate() {
	onEntityUpdate();
}

@Override
public void onEntityUpdate(){
	for (int i1 = 0; i1 < 2; i1++) {
		worldObj.spawnParticle("crit", posX + (motionX * i1) / 4D, posY + (motionY * i1) / 4D, posZ + (motionZ * i1) / 4D, -motionX, -motionY + 0.2D, -motionZ);
	}
	ticksInAir++;
	if(ticksInAir == 16){
		bounceBack();
	} else if(ticksInAir == 32){
		setDead();
	}
}

@Override
public void onImpact(MovingObjectPosition p_70184_1_) {
	bounceBack();
}

protected void bounceBack() {
	setVelocity(-velX, -velY, -velZ);
}

@Override
protected float getGravityVelocity() {
        return 0F;
    }
}

 

 

This is the Entity V2:

 

package arekkuusu.grimoireOfAlice.entity;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

public class EntityEllyScythe extends EntityThrowable{

protected int ticksInAir;

public EntityEllyScythe(World p_i1773_1_) {
        super(p_i1773_1_);
        ticksInAir = 0;
    }

    public EntityEllyScythe(World p_i1774_1_, EntityLivingBase p_i1774_2_) {
        super(p_i1774_1_, p_i1774_2_);
        ticksInAir = 0;
    }

    public EntityEllyScythe(World p_i1775_1_,Vec3 pos, Vec3 vel) {
        super(p_i1775_1_, pos.xCoord, pos.yCoord, pos.zCoord);
        setVelocity(vel.xCoord,vel.yCoord,vel.zCoord);
        ticksInAir = 0;
    }
    
@Override
public void onUpdate() {
	onEntityUpdate();
}

@Override
public void onEntityUpdate(){
	for (int i1 = 0; i1 < 2; i1++) {
		worldObj.spawnParticle("magicCrit", posX + (motionX * i1) / 4D, posY + (motionY * i1) / 4D, posZ + (motionZ * i1) / 4D, -motionX, -motionY + 0.2D, -motionZ);
	}
	ticksInAir++;
	if(ticksInAir == 16){
		bounceBack();
	} else if(ticksInAir == 32){
		setDead();
	}
}

@Override
public void onImpact(MovingObjectPosition mop) {
	if(mop.entityHit != null) {

		float throwDamage = 5;
		mop.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, getThrower()), throwDamage);

		if(mop.entityHit instanceof EntityLivingBase) {
			byte b0 = 0;

			switch(worldObj.difficultySetting) {
				case NORMAL:
					b0 = 10;
					break;
				case HARD:
					b0 = 40;
					break;
				default:
					break;
			}

			if(b0 > 0) {
				((EntityLivingBase)mop.entityHit).addPotionEffect(new PotionEffect(Potion.wither.id, 20 * b0, 1));
			}
		}

		for(int l = 0; l < 4; ++l) {
			worldObj.spawnParticle("magicCrit", posX, posY, posZ, 0.0D, 0.0D, 0.0D);
		}
	bounceBack();
	}
}

protected void bounceBack() {
	setVelocity(-motionX, -motionY, -motionZ);
}

@Override
protected float getGravityVelocity() {
        return 0F;
    }
}

 

 

The Item:

@Override
public void onPlayerStoppedUsing(ItemStack itemstack, World world, EntityPlayer entityplayer, int i){
	world.playSoundAtEntity(entityplayer, "random.bow", 0.6F, 1.0F / (2F * 0.4F + 1.0F));
	Vec3 look = entityplayer.getLookVec();
	Vec3 position = Vec3.createVectorHelper(entityplayer.posX, entityplayer.posY, entityplayer.posZ);
	EntityEllyScythe EllyScytheProyectile = new EntityEllyScythe(world, look, position);
	if (!world.isRemote){
		world.spawnEntityInWorld(EllyScytheProyectile);
	}
}

 

And the render:

 

package arekkuusu.grimoireOfAlice.client.render;

import net.minecraft.client.Minecraft;
import net.minecraft.client.model.ModelBase;
import net.minecraft.client.renderer.Tessellator;
import net.minecraft.client.renderer.entity.Render;
import net.minecraft.entity.Entity;
import net.minecraft.util.MathHelper;
import net.minecraft.util.ResourceLocation;

import org.lwjgl.opengl.GL11;

import arekkuusu.grimoireOfAlice.client.model.ModelEllyScythe;
import arekkuusu.grimoireOfAlice.entity.EntityEllyScythe;
import arekkuusu.grimoireOfAlice.lib.LibMod;

public class RenderEllyScytheProyectile extends Render {

protected ModelBase model = new ModelEllyScythe();
private static final ResourceLocation TEXTURE = new ResourceLocation(LibMod.MODID, "textures/models/EllyScythe.png");

@Override
public void doRender(Entity entity, double par1, double par2, double par3, float par4, float par5) {
	GL11.glPushMatrix();
	bindEntityTexture(entity);
	GL11.glTranslated(par1, par2, par3);
	GL11.glRotatef(90F, 0.0F, 0.0F, 1.0F);
	model.render(entity, 0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0625F);
        GL11.glPopMatrix();
}

@Override
protected ResourceLocation getEntityTexture(Entity p_110775_1_) {
	return TEXTURE;
}

}

 

 

The ClientProxy*:

RenderingRegistry.registerEntityRenderingHandler(EntityEllyScythe.class, new RenderEllyScytheProyectile());

 

More specificly:

- The render is invisible in V2 / it uses a snowball when using V1

- The onImpact does not damage mobs

- The onUpdate worldObj.spawnParticle("magicCrit"... does not leave a trail of particles...

- The getGravityVelocity() set to 0F in V1 makes it fall / in V2 I cannot know because I cant see it...

Renderers should only be registered in the ClientProxy - you mentioned you did so in your CommonProxy.

 

What version of Minecraft are you modding for?

 

Show your entity registration code for v2.

 

You should at least be calling super#onEntityUpdate if not also super#onUpdate. Lots of important things happen there...

Oh sorry, just named it ClientProxy.... it is a  Client thing tho

You didn't answer any of my questions or post any requested code... -.-

Version is 1.7.10

 

Its the same for both?

Vec3 look = entityplayer.getLookVec();
	Vec3 position = Vec3.createVectorHelper(entityplayer.posX, entityplayer.posY, entityplayer.posZ);
	EntityEllyScythe EllyScytheProyectile = new EntityEllyScythe(world, look, position);
	if (!world.isRemote){
		world.spawnEntityInWorld(EllyScytheProyectile);
	}

 

So super.onUpdate(); goes in the constructor...? why should I call it?

[coolAlias]

No, super#onUpdate goes in the overridden #onUpdate method in your Entity class. You need to call it because the method does TONS of stuff in the super classes, and by not calling it you are preventing your Entity from working properly.

 

Note also that the super method automatically calls #onEntityUpdate - why are you overriding that method instead of just putting your logic in #onUpdate (before or after calling super)?
