Need help printing text in simulation

[KodoCoder]

Hey all,

I'm trying to check if part of my program is working correctly, but I'm not sure how to print things and have them displayed during the simulation. There's text at the top of the demo I'm modifying--RagdollDemo--that starts with "Profiling : Root (total run time..." Is there any way to access that, or is there a better way to output text while looking at my simulation?

Best,
Josh

To stop showing profile info you can either:
1) add the following line to DemoApplication.h
#define BT_NO_PROFILE
Or even better you can
2) override the function that calls showProfileInfo(..)


To print something on the screen you can use DemoApplication::displayProfileString(..):
sprintf(str,"Time: %f sec.", m_timeStamp);
displayProfileString(20, 50, str);

These two lines should be added both to
clientMoveAndDisplay(..)
and
displayCallback(..)

So you need either to edit these functions in DemoApplication.cpp or better override them.

See Demos/ForkLiftDemo: you can simply use

Code: Select all

GLDebugDrawString(xStart,yStart,text);

Upcoming Bullet 2.83 has improved graphics debugging/GUI features, in particular for OpenGL 3+ GPUs.

Thanks for the help! I appreciate all the help I've been getting on these very basic questions.
