Someone can send me the link of bukkit, I want create one plugin what usage one command create one home. More i don't know how i change blocks air. with x, y, z.
i want to break free. kidding. i want to create one home automatically with only command. i got what know about blocks managements
So you want to make a teleport plugin where the user just types /home, correct? To get the location use Player.getLocation() and then .getX(), .getY(), .getZ() etc...
I think he wants to *build* a house on a command use, maybe? If so, check out World.getBlockAt and the Block methods: https://github.com/Bukkit/Bukkit/blob/master/src/main/java/org/bukkit/World.java
Well then I recommend looking at the documentation NathanWolf provided, if you still require further help understanding the documentation then reply to mine or Nathan's posts.
