a doubt about if the the world matrix of AbstractMesh is cached?


Recommended Posts

hi guys,

i just updated from babylon 2.2 to 2.3,

everything look fine, except this:


i have such a senario,

i have a cannon in the scene,

the barrel of cannon rotates with mouse move.


i get the world matrix of barrel's AbstractMesh with "getWorldMatrix()",

then use the matrix to translate start position of bullets,


now with babylon 2.3,

the translated position of bullets look a few frames delayed after the rotating barrel.

i doubt, if the world matrix got with "getWorldMatrix()" is read from cache?


how can i calculate it in real time?

thank you.
