I was wondering what c= does because I was trying to make like a last man standing thing but I just don't know how the command block will sense there is only one still in and that person is the winner. I know this has not much to do with the map but I really didn't know where else to find the answer if you could help me think of a way to do that it would be awesome.

/tellraw:

/tellraw @a {text:"Hello!",color:red,bold:true,underlined:false,italic:false,strikethrough:false,obfuscated:false}

Bold will make the text thicker and bigger, Color will change color of course, underline will underline the text, italic will put the text into italic, strikethrough will strike a bar through the text, and obfuscated will make the text glitchy and mess up.

Proximity Detectos: Make a simple clock, by putting a commandblock down, and using this command

/setblock ~ ~1 ~ redstone_block 0 destroy

Then put a redstone block on top of it, it will make the fastest clock in the game. then put another command block next to the redstoneblocks and use this command

/testfor @e[type=Player,r=[CHANGE BLOCK RADIUS HERE] ]

then with a comparator connect the testfor command with whatever you want to happen. but make sure you do this in 1.8 as @e is only in the snapshots as of now

Can you make a MAP that teaches us to create custom villager trades,www.minecraftforum.net/topic/1969520-17-using-summon-give-datatags-in-map-making-tutorials/
