Throughout a day i tried to understand what each variable does, and at the end of a day, i finally got it, but what EXACTLY (difference between) setRotationPoint and addBox does - idk
Alias for setRotationPoint = "srp", addBox = "ab"
-----------------NERD-TALK-----------------
SO, the most sussy value is Y-axis. Starting from srp, 24.0F - is height +0, meaning a starting point. in ab, 0.0F is also height +0. When you decrement srp or ab y-axis values - you get height +1 with each -1, meaning you can interpretate same height in infinite ways, same for X axis but srp starting point is 0.0F, note that none of each applies to Z axis - it is 'normal'
For example, task: Place cube with dimensions 3, 3, 3 to coords -1.5, 6, -4.
My theory approach: Decrement cube Y dimension from ab value, and decrement srp value until satisfied(3 in this case).
I think X and Z axis do not need explanation, but still: you can set -1.5 and -4 to either srp or/and ab
-------------INTERESTING-PART-------------
this.head = new ModelRenderer((ModelBase)this, 0, 10)). addBox(-1.5f, -3.0f, -3.0f, 3, 3, 3);
# For X and Y axis - decrement its dimension to get position 0. To achieve -1.5 in X axis - add this reverted value to srp/ab (ab in this case)
this.head.setRotationPoint(0.0f, 21.0f, -2.0f); # Decrementing 3 to achieve "6" height (you can do so with ab value, but NOTE that i don't know the difference between both)
Edit: I Figured it out by playing with java entity class file for forge 1.7.10
Hope this helps someone if you went this far somehow
