coding question

I've looked all over and can't find an answer to my question, so I'll post it for you.
In the examples, the color settings are something along the lines of:
(255,255,255,255) What is that 4th number? RGB is only 3.

also, when looking at size of an object, it's using something like (0.0f) ??huh?? I'm trying to understand these things.

its f32! and when you give the size, rotation etc. its vector3df which contains f32 i guess

A color code with four components is called ARGB. On a total of 32bits, each one can be allocated 8 bits. 2^8 = 256 hence the 0-255 range.

As for f32, its Irrlicht's type definition for a 32bits float. It ensures portability.

Thanks. That answers those.
