Write your own macro that does the job:
Code:
#define setEmask(ent, flag) ent.emask |= flag
#define resetEmask(ent, flag) ent.emask &= ~flag
#define toggleEmask(ent, flag) ent.emask ^= flag
#define isEmask(ent, flag) ent.emask & flag


Its just like the set, reset, toggle and is macros that are already defined for you in the engine.
