I understand how to use the chain command block etc., but I was just wondering if there was anyway to use the if/then command in one command if that makes sense.

Can you give me the command so I could help you?

If you mean change multi command lines into one line you can do it by using scoreboard

i guess you could just use a comparator

Comparators are for True/False not If/Then

I know but they could work. If a testfor command is true (see the "if") the comparator will activate. With enough True/False conditions, I guess you can create an If/then chain (ex: "/testfor (playername)[score_scoreboardname_min=1,score_scoreboard=1]", couldn't it can basically mean "if (playername) has a scoreboard score of 1, then activate other command (via comparator)

I don't have the exact command but what I'm trying to do is

/testfor @p[lm=5]



and then if true it takes those 5 xp levels away, and then gives them a new item entitled "5 xp".



Again thank you for the help it truly means so much you have no idea. 

I've created a help command block creation on my PMC account.

It works as such: {onRightClick:{event:AllowFlight},Particle:flame}

But if you do not want to install modifications, you can always use the detect feature if you want to detect a block and then run an action.

Example:

/execute @a ~ ~ ~ detect ~ ~-1 ~ grass 0 /say hi

Well what you are asking is exactly an if/then situation. The only problem is that even in real programming, this is a multi-lined, or compound, "then".

Meaning, you cannot accomplish the removal of the levels and giving of the item without two separate commands. However, to answer your original question, yes you can make an if/then in one command:

/execute @a[lm=5] ~ ~ ~ xp -5L

What this command can be translated to is:

If a player has at least 5 levels, then remove 5 levels.

Since this still does not accomplish your requirements, here is a solution:

/scoreboard players tag @a[lm=5] add act

/xp -5L @a[tag=act]

/give @a[tag=act] minecraft:dirt 1 0 {display:{Name:"5 xp",Lore:["Look at you...","You managed to get 5 levels","Have some useful dirt!"]}}

/scoreboard players tag @a[tag=act] remove act

Now this can be translated to this in pseudo code:

if (player.level >= 5) {

player.addLevel(-5)

player.giveItem(...)

}

Or in other, actual, words:

if player's level is at least 5, then

remove 5 levels from player

give them the special item

done

Using the first command this is what came up: [19:07:23] Failed to execute 'xp -5L' as Byslic. Again thanks for the help!

That first command was simply an example you would actually do this:

/xp -5L @a[lm=5]
