How to animate your custom mob tutorial

Hello! My name is Igor! FOR VERSIONS 1.7.9.1.8.0 etc ... FROM MCREATOR

Today I will teach you how to animate your custom mob!

1. Create your mob! And save it in ".java" format
2. Then right-click the file and open it with a text editor (preferably Notepad ++)
3. Roll over there at the end! You'll see this code:

public void setRotationAngles (float f, float f1, float f2, float f3, float f4, float f5, entity Entity)
  {
    super.setRotationAngles (f, f1, f2, f3, f4, f5, entity);
  }

}

4. Copy the code of the site: https://pastebin.com/ksq1S6rK

5.Paste the code exactly like this:
public void setRotationAngles (float f, float f1, float f2, float f3, float f4, float f5, entity Entity)
  {
    super.setRotationAngles (f, f1, f2, f3, f4, f5 entity);
    this.head.rotateAngleY ​​= f3 / (180F / (float) Math.PI);
    this.head.rotateAngleX = f4 / (180F / (float) Math.PI);
    this.leftleg.rotateAngleX = MathHelper.cos (f * 1.0F) * -1.0F * f1;
    this.rightleg.rotateAngleX = MathHelper.cos (f * 1.0F) * 1.0F * f1;
    this.rightarm.rotateAngleX = MathHelper.cos (f * 0.6662F + (float) Math.PI) * 2.0F * f1 * 0.5F;
    this.leftarm.rotateAngleX = MathHelper.cos (f * 0.6662F + (float) Math.PI) * 2.0F * f1 * 0.5F;
  }

}

6.Replace or add parts according to your mob eg if you have horns:
  {
    super.setRotationAngles (f, f1, f2, f3, f4, f5, entity);
    this.head.rotateAngleY ​​= f3 / (180F / (float) Math.PI);
    this.head.rotateAngleX = f4 / (180F / (float) Math.PI);
    this.righthorn.rotateAngleY ​​= f3 / (180F / (float) Math.PI);
    this.righthorn.rotateAngleX = f4 / (180F / (float) Math.PI);
    this.lefthorn.rotateAngleY ​​= f3 / (180F / (float) Math.PI);
    this.lefthorn.rotateAngleX = f4 / (180F / (float) Math.PI);
    this.leftleg.rotateAngleX = MathHelper.cos (f * 1.0F) * -1.0F * f1;
    this.rightleg.rotateAngleX = MathHelper.cos (f * 1.0F) * 1.0F * f1;
    this.rightarm.rotateAngleX = MathHelper.cos (f * 0.6662F + (float) Math.PI) * 2.0F * f1 * 0.5F;
    this.leftarm.rotateAngleX = MathHelper.cos (f * 0.6662F + (float) Math.PI) * 2.0F * f1 * 0.5F;
  }

}

7. Good! Go exploring the world of animations! Now just add mob in mod!

QUESTIONS:
My model was all wrong what happened? Make sure your body's animation points are correct to avoid mistakes!
Should I always do this before adding a template? Not that I know of, after adding animation to a mob, MCreator seems to have recognized the code and validated it for everyone!
Other questions, I'm here!
