ok,dishes how to install add-ons the right way.since all the others were like "place it in ur add-ons folder n00b."i was like "ok,what?"so here it is. :3
1.be sure blockland is closed.not minimized,closed.push quit,or if you are building,save it and quit.
2.find an add-on.(i recommend dual mac10 by peaceful war,that was my first.)
3.download and push SAVE instead of OPEN.
since people dstupid things like "go to c-blockland-addons"and that dosent make sense,push start on your toolbar,go to computer.go to OS:C,or where you downloaded blockland,go to blockland,then click on add-ons NOT on the taskbar,on the middle part.
4.click save on the bottom when you are there.
when its done,you will hear a "ding" from your computer.
5.start blockland and push start game,and check it off in the list.you do this same thing for ALL add-on types.
k thx bai ^-^
