Identify mistakes you are making that you can improve upon in the process.
Sometimes you need these edits for smart decisions. For example, this could come in handy in a case where you were in the final 5 of a solo match. You would have to build a 1-by-1 cube. You would have to edit a window to see if you can snipe or shoot at the other 4 players. A lot of people edit through platforms to land on people with a shotgun or an assault rifle.
Walls are a little harder because you have to be quick with your edits. Otherwise the opponent can pickaxe or shoot down your wall and place his or her own wall. Learn the ramps. Ramps are a little more complicated because of their 3 dimensional editing. Ramps can go into an up or left/right stairway, or they can turn backwards from the opposite direction of the original build.
Editing is used in 1v1’s, build battles, solo, squads, duos, and basically everything in Fortnite Battle Royale. So get out there and build the biggest house or build an apartment with doors and windows!
