Ok, so there is a strange thing in mob's animations. So, looks like i want my mob to perform walking animations, i do.

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.rightleg.rotateAngleX = MathHelper.cos(f * 0.5F) * -1.0F * f1;
this.leftleg.rotateAngleX = MathHelper.cos(f * 0.5F) * 1.0F * f1;

this.rightarm.rotateAngleX = MathHelper.cos(f * 0.5F) * -1.0F * f1;
this.leftarm.rotateAngleX = MathHelper.cos(f * 0.5F) * 1.0F * f1;
  }

}

 

And it works, but always when i set an animation on any limb, on X angle, the rotation of that limb on X angle is become 0. I know its hard to understand. So let me explain better

 

Here is the part of code of your ModelMob.class

leftarm = new ModelRenderer(this, 120, 29);
      leftarm.addBox(-8F, 5F, -1.8F, 2, 12, 2);
      leftarm.setRotationPoint(8.5F, 3F, 3F);
      leftarm.setTextureSize(128, 64);
      leftarm.mirror = true;
      setRotation(leftarm, -0.5420432F, 0F, 0F);

 

You see, that setRotation is going on -0.5, so basicly that arm is a littlebit turned in game. But when i use an animation...

this.leftarm.rotateAngleX = MathHelper.cos(f * 0.5F) * 1.0F * f1;

 

... in game, that arm perform animation while mob is walking, but when he is idle, that arm is no more turned. Its now straight down on X angle. So before i set animations it was (-0.5F) in game, after that its (0F). Any ideas on how to fix it?

Anybody?

imo, pretty hard to understand.

Look. So, on the first pic you see, that i have this code in my ModelMob.class:

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.rightupperleg.rotateAngleX = MathHelper.cos(f * 0.5F) * -1.0F * f1;
this.leftupperleg.rotateAngleX = MathHelper.cos(f * 0.5F) * 1.0F * f1;

this.rightupperarm.rotateAngleX = MathHelper.cos(f * 0.4F) * -1.2F * f1;
this.leftupperarm.rotateAngleX = MathHelper.cos(f * 0.4F) * 1.2F * f1;


  }

So, only rightarm is childed by rightupperarm, so its moving with it. But when i do so:

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.rightupperleg.rotateAngleX = MathHelper.cos(f * 0.5F) * -1.0F * f1;
this.leftupperleg.rotateAngleX = MathHelper.cos(f * 0.5F) * 1.0F * f1; 



this.rightupperarm.rotateAngleX = MathHelper.cos(f * 0.4F) * -1.2F * f1;
this.leftupperarm.rotateAngleX = MathHelper.cos(f * 0.4F) * 1.2F * f1;
this.rightarm.rotateAngleX = MathHelper.cos(f * 0.5F) * -1.0F * f1; // i just added these
this.leftarm.rotateAngleX = MathHelper.cos(f * 0.5F) * 1.0F * f1; // i just added these


  }

...mob's arms are straight down.

So, basicly you see on the first picture, that the both lowerarms ( which is rightarm,leftarm in the code ) are rotated a littlebit( while mob is idle ), but when i set to them animations while walking (rightarm, leftarm), they made not rotated( while mob is idle ) by the X Angle (  because rotateAngleX ), thats on the second picture. I HOPE you understand.

So, did you understand? Before i add walking animations, while mob is idle he was having arm like this "/" but when i added walking animations, now while he  idle, his arms was looks like this "|". Any guesses on how to add walking animations on limb and make that limb rotated how i want

Not really, unless I'm missing something obvious.

Basic math.

From your code, when you have a rotation of 0° (which is idle), the code only multiplies values which means 0 * [a value] * [another value] = 0

And yes, Math.cos(0) is 1, but the second parameter (here f1) is also 0, so in all it's 0

 

When it moves, the values have a value != 0, so you'll have a difference between the rotation of the upper and lower part, since they multiply with different values.

 

 

Solution? Add a standard rotation to the calculated value, like rightarm.rotateAngleX = Math.cos(...) * ... + [rotation]

Play with the value of [rotation] until it's right. Or take the value from the model constructor, where you initialize the rightarm ModelRenderer.

 

Little note: I made the effort and tried to find out what those setRotationAngles (and some other methods) parameters mean (or what they should be called). You can see the result here:
