Building is a big part of Fortnite, and Epic Games has revealed some construction improvements geared to speed things up in both Battle Royale and Save the World come v.3.0.0. The combination of turbo building (holding down primary fire continuously placing building pieces) and automatic material swapping when you deplete one resource will allow players to build on the run. As in, build a ramp as you run up it! The rules for building collision have also changed: Larger items like rocks, trees, and vehicles will no longer block structures. However, all structures will still need a connection to a floor or terrain.
The final change is speeding up switching between building pieces by removing the need for that command to travel through Epic’s servers. This change is only slated for Battle Royal currently, but devs plan to get it into Save the World as well.
