Irrlicht Engine

in simple terms, how can i apply gravity to the irrlicht FPS camera using bullet sdk or irrbullet?. A short code snipet would be appreciated since they are in short supply.

Thanks

i want to use bullet sdk for collision detection but am suffering from lack of good examples.
Typically most 3D objects in a game are represented by two separate meshes or shapes....
a second highly simplified invisible mesh is used to represent the object to the physics engine from http://en ...

i keep seeing types like f32, u32, etc. i assume that they stand for float and unsigned int.
questions
1.why don't you use familiar types like float and unsigned etc, etc.
2.where is the documentation about these types.

Thanks in advance

whenever i use the software renderer with examples that involve loading a quake3map eg example 3 in the irrlicht tutorials ,it shows less than desirable images. Is it just me or is this a known issue. Does it have a solution?

here is the full source code (copy and pasted)

#include<irrlicht.h>

using namespace irr;

using namespace video;

using namespace io;

using namespace scene;

using namespace core;



int main()

{

IrrlichtDevice * device= createDevice(video::EDT_OPENGL);

if(!device) return 1;

i am trying to apply gravity to the models in tutorial 7 (- collision detection )instead of setting their position on the floor manually

1. first i commented out these lines
//selector->drop(); // As soon as we're done with the selector, drop it
//node->setPosition(core::vector3df(-70,-15,-120 ...
