I have made 2 commands for you,if the player does /visible other players can see him on minimap with a marker with same color as his color,and if he does /visible again others cant see him on minimap as a marker,and if you /disable all of the markers of the players will disappear for you,i mean others can see it if they got disable off but you cant,if you do /disable,all of the guys that have invisible == 1 will appear on your minimap,i made it select able,i mean player can toggle markers on map or see the markers on the minimap,i did the best commands for you
0xFFFFFF00 means invisible
