why is the element "body" in ModelQuadruped.java created 90 degrees off?

[pinkandfluffy]

I'm a newbie and I try to understand why the element "body" in ModelQuadruped.java is created 90 degrees off? Like this:

 

this.body.addBox(-5.0F, -10.0F, -7.0F, 10, 16, 8, scale);

 

Then it is rotated to its correct place by

 

this.body.rotateAngleX = ((float)Math.PI / 2F);

 

Why not make it

 

this.body.addBox(-5.0F, -10.0F, -7.0F, 16, 10, 8, scale);

 

from the beginning?

 

Do you understand what I mean?

 

My 11 yo wants to learn how to mod and I am supposed to help..and I'm already stuck..

The only thing I can think of is texture coordinates: fitting all the boxes cleanly onto the texturemap without overlapping or leaving large void areas.

Thank you so much!

I think it is probably because they based it on the biped (i.e. player) model. If you think about a quadraped, you just take a biped and rotate the body.

Thank you both :)
