setVertexShaderConstant() deprecated for matrix variable

[afuzzyllama]

While working with the following code in tutorial 10*:

Code: Select all

 
core::matrix4 invWorld = driver->getTransform(video::ETS_WORLD);
invWorld.makeInverse();
services->setVertexShaderConstant("mInvWorld", invWorld.pointer(), 16);
 

The following function call:
irr::video::IMaterialRenderServices::setVertexShaderConstant()

is marked as deprecated. What is the proper way to set a matrix vertex shader constant?

Seems you use new svn trunk. Check the tutorial 10 in there (in examples folder), but basically it's now 2 functions.
With getVertexShaderConstantID you get a register id for the shader constant. And there's a new setVertexShaderConstant which takes that id instead of a name. Note that the old solution will still work for now, it's just slower because it's using constantly string-comparisons in rendering which is rather slow while working with id's is a lot faster.

Makes sense. Thanks for pointing me in the right direction!
