How wear weapon on 3d model ?
Author
Hi everybody,
I watched Jim Adams "advanced animation" and RPG book. I want character (e.g.tiny or warrior model) can wear weapon (e.g. sword) with new book engine?
But How to do ?
Finally, i want know which people migrate RPG ''Tower'' code with new book engine and when Jim will release this code on web site?
Thank a lot.
It is part of my source code (DoFrame function)
Character and weapon can be render, but weapon cannot put on correct position.
Normally, you specify (in the model, or possibly procedurally) where the weapon should ''attach'' to the character, and then render the weapon relative to that position (usually you define a weapon''s ''attach point'' as well, since most weapons aren''t held at the center or end).
Sometimes (depending on the complexity of the weapon / item you want the character to hold), you have to specify a unique location for each item.

Hi Etnu,
Thank your reply.
I got basic idea. I try got bone frame matrix (e.g weaponhand) and set world position and render it.
Which steps are mistake ? I have no idea now....
But i will work hard to solve this problem.
By the way, I want know which people migrate RPG ''Tower'' code with new book engine and when Jim release this code on web site? hahaha..

I solved this problem. Thanks
work case
rendermatrix=bone combined matrix * world transform matrix
no work case ( I don''t know why..)
rendermatrix=world transform matrix * bone combined matrix
work sample code

Matrix multiplication is not commutative. So, as you learned the order of multiplication is important.
