I'm creating a mage that shoots balls of fire, however I can not do it and  need your help, please help me ...

Show what you have tried.

 

I tried to adapt this code:

 


pprotected void attackEntity(Entity entity, float f)
    {
        if (f < 10F)
        {
            double d = entity.posX - posX;
            double d1 = entity.posZ - posZ;
            if (attackTime == 0)
            {
                EntitySnowball entitysnowball = new EntitySnowball(worldObj, this);
                double d2 = (entity.posY + (double)entity.getEyeHeight()) - 1.1000000238418579D - entitysnowball.posY;
                float f1 = MathHelper.sqrt_double(d * d + d1 * d1) * 0.2F;
                worldObj.playSoundAtEntity(this, "random.bow", 1.0F, 1.0F / (rand.nextFloat() * 0.4F + 0.8F));
                worldObj.spawnEntityInWorld(entitysnowball);
                entitysnowball.setThrowableHeading(d, d2 + (double)f1, d1, 1.6F, 12F);
                attackTime = 10;
            }
            rotationYaw = (float)((Math.atan2(d1, d) * 180D) / 3.1415927410125732D) - 90F;
            hasAttacked = true;
        }
    }

You need an AI task to make your Entity actually do something. The snow golem for example uses EntityAIArrowAttack.

 

I used the following code, and it worked almost perfectly, the only problem is, the fireballs instead of being out of the mob are coming out of my player

 

@Override
		public void attackEntityWithRangedAttack(EntityLivingBase entity, float arg1) {

			Vec3 look = entity.getLookVec();
			EntityLargeFireball fireball2 = new EntityLargeFireball(worldObj);
			fireball2.setPosition(entity.posX + look.xCoord * 5, entity.posY + look.yCoord * 5, entity.posZ + look.zCoord * 5);
			fireball2.accelerationX = look.xCoord * 0.4;
			fireball2.accelerationY = look.yCoord * 0.4;
			fireball2.accelerationZ = look.zCoord * 0.4;
			this.worldObj.spawnEntityInWorld(fireball2);
		}

You are using the entity being passed in as the "source" of the projectiles. But the entity you get as the parameter is the entity being attacked, not the entity that is doing the attack.

 

and how I could change to the entity that will make the attack, i tried to change some parts,however at the end, just did not work

It is a method in your Entity. Thus 

this

refers to your Entity.

 

I fix and now my body is firing fireballs, but after he started shooting for a part he did not "upgrade" and is always there to shoot, but if I get away and return back, he start shoot for one only direction, it returns with bug

 

@Override
		public void attackEntityWithRangedAttack(EntityLivingBase entity, float arg1) {

			Vec3 look = this.getLookVec();
			EntityLargeFireball var3 = new EntityLargeFireball(this.worldObj, this, 1, 1, 1);
			var3.setPosition(this.posX + look.xCoord * 1, this.posY + look.yCoord * 1, this.posZ + look.zCoord * 1);
			var3.accelerationX = look.xCoord * 0.3;
			var3.accelerationY = look.yCoord * 0.3;
			var3.accelerationZ = look.zCoord * 0.3;
	        this.worldObj.spawnEntityInWorld(var3);
		}

This is the code from EntityBlaze I put into my own mob. It works perfectly, as I will explain below. (Hopefully accurately.)

 

    @Override
    public void attackEntityWithRangedAttack(EntityLivingBase entity, float distance) {

        double d0 = entity.posX - this.posX;
        double d1 = entity.boundingBox.minY + (double)(entity.height / 2.0F) - (this.posY + (double)(this.height / 2.0F));
        double d2 = entity.posZ - this.posZ;

 

This calculates the x,y,z DISTANCE between the projectile and the target. getLook() only gives the DIRECTION.

 

        float f1 = MathHelper.sqrt_float(distance) * 0.5F;

 

This is calculating the accuracy (randomness) of the projectile. (The square root of the total distance divided by half. So, larger distances are more accurately fired.)

 

        this.worldObj.playAuxSFXAtEntity((EntityPlayer)null, 1009, (int)this.posX, (int)this.posY, (int)this.posZ, 0);
        for (int i = 0; i < 1; ++i)
        {

 

This part has a for loop because the Blaze can fire three fireballs at a time, but it's not needed in this case.

 

            EntitySmallFireball entitysmallfireball = new EntitySmallFireball(this.worldObj, this, d0 + this.rand.nextGaussian() * (double)f1, d1, d2 + this.rand.nextGaussian() * (double)f1);

 

This is the important part. This sets the x,y,z vector of the projectile, it uses the distance numbers calculated above, times a random number. (Because the Blaze fires randomly), you can take out "this.rand.nextGaussian() * (double)f1" and the projectile will always hit you dead on.

 

            entitysmallfireball.posY = this.posY + (double)(this.height / 2.0F) + 0.5D;

 

This is where the projectile starts, the 0.5 is added to half the height to place it near the mobs mouth area.

 

            this.worldObj.spawnEntityInWorld(entitysmallfireball);
        }
    }

 

Done. My class extends EntitySkeleton and nothing but this method is in it. I spawned it in, and now I have a skelington that shoots (Inaccurate) fireballs instead of arrows.

      WIZARD WEB RECOVERY TRUSTED BITCOIN RECOVERY EXPERT

      By Jessica Andriese · Posted

      There's a scheme I got into where they promised to trade Bitcoin for me and take a cut as a commission. Seemed like a good idea at the time. But then, things went south real fast. They ended up transferring   $190,000 worth of my Bitcoin. I was devastated and felt completely helpless. That's when I stumbled upon the Wizard Web Recovery Tool. It was like a beacon of hope amid chaos. With this tool, I could finally start digging into what went wrong and hopefully get my Bitcoin back. Using Wizard Web was surprisingly easy. I just had to plug in some details about my Bitcoin account and let it do its thing. It started scanning the internet, looking for any clues about what happened to my Bitcoin. It felt like having a detective on my side, searching for answers. And guess what? Wizard Web found some leads. It uncovered evidence of the scheme's shady dealings and helped me track down the people responsible for losing my Bitcoin. Armed with this information, I took the case to court. After a long and hard-fought legal battle, the court ruled in my favor. The perpetrators were held accountable for their actions and faced criminal charges for their involvement in the scheme. It was a victory not just for me, but for anyone who's been taken advantage of by these kinds of scams. Thanks to Wizard Web Recovery, I was able to get justice and reclaim what was rightfully mine. It showed me that even in the face of adversity, there's always a way to fight back. And with the right tools and determination, anything is possible.   The following is the contact information for Wizard Web Recovery.   Email: wizard web recovery((@))programmer . net

      unknown Bug

      By xXalex925ii529xelaXx · Posted

      Hello, good morning. I know some programming and I'm interested in mod creation. That's why I've decided to follow a tutorial guide on YouTube by TurtyWurty. https://www.youtube.com/watch?v=DhoX9cmAZqA&t=160s&ab_channel=TurtyWurty I've followed the tutorial perfectly. The problem is that when checking the food, the texture doesn't load for me. However, everything seems fine no matter how much I check. I'm sure it's something trivial, the problem is that I can't find it. Could you help me solve it, please? I leave a zip of my file so you can edit it freely. forge-1.20-Civicraft.rar

      If you have nvidia graphics, it's important that you make sure Minecraft (and anything Minecraft-related) is set to prefer high performance graphics first. If you only update your AMD drivers it might fix the issue but cause severe performance loss vs Vanilla as it'll be running on the integrated graphics instead of dedicated nvidia graphics
