I wanna know one grammar

[doojin]

I saw JetEngine source.

typedef struct
{
jeVec3d World;
jeVec3d Normal;
jeRGBA Color;
float u, v;
float pad1,pad2;
} jeVertex; // 64 bytes !

why do people use typedef?

my style is

struct jeVertex
{
jeVec3d World;
jeVec3d Normal;
jeRGBA Color;
float u, v;
float pad1,pad2;
};

Are there some reason?

yes, C. In C using your 'style' you'd have to use "struct jeVertex v;"
instead of just "jeVertex v;".
