Map Reveal at the start of the match Thread - SC Revolution Mod for StarCraft

This code is pretty simple
We need to reveal each tile of the map and also reveal every mineral field and and gas geyser. So we can do it like this:

     void exploreMap(){ 
		for(int x = 0; x < mapTileSize->width; x++) { 
			for(int y = 0; y < mapTileSize->height; y++) { 
				ActiveTile *currentTile = &(*activeTileArray)[(x) + mapTileSize->width * (y)]; 
				currentTile->exploredFlags = 0; 					
			} 
		} 
		//if vespene geyser or a mineral field, reveal it to all players
		for (CUnit *unit = *firstVisibleUnit; unit; unit = unit->link.next) {
			if (unit->id==188 || (unit->id >= 176 && unit->id <= 178)){
				unit->sprite->visibilityFlags=0xFF; 
			}
		}
	}

And we call the exploreMap() function on the block that execute at the start of every match in game_hooks

if (*elapsedTimeFrames == 0) {
    if(*GAME_TYPE != GameType::UseMapSettings) { //not an UMS map
	exploreMap();
    }
}

Is there any difference between

unit->sprite->visibilityFlags = 127; 

and

unit->sprite->visibilityFlags = 0xFF; 

????

Yeah 0xFF (or 255) is the correct value. i dont know why i use 127 (probably i assume that the first bit was for neutral, but there are 8 bits so one for each player)
Thanks for pointing that out.
