Leveling Up Class and Danger in Unreal Editor for Fortnite | Unreal Editor for Fortnite Documentation

Raise the stakes for players by leveling up the danger with each nightfall. Higher levels of danger coincide with an increase in the player's class and weapon strength. This makes the game engaging and gives the player a chance to increase their skills.

In this example, each time the player triggers the Nightmare Day Sequence device they also trigger a Creature Spawner and a Class Selector device. Increasingly more difficult creatures spawn with each night sequence. The player’s class is leveled up at the same time as a new horde of creatures spawns. Each new class provides a more powerful weapon to the player's weapons cache, giving them a better chance to defeat the creature hordes.

Devices used are:

Class Selector
Item Spawner
Creature Spawner
Guard Spawner
AI Patrol Path Node
Danger Volume
Prop Mover

Leveling Up Class and Weapons

Class selectors increase the player's class level as they progress through the game. Each time a player's class levels up, they're provided with a more powerful weapon. All weapons stay equipped, providing the player with a cache of weapons.

Class Selector

Modify the user options on the first Class Selector then duplicate the device as many times as you need to level up a player toward the boss fight at the end of the game.

Option	Value	Explanation
Class to Switch to (This option needs to be set to True in order to modify its options.)	Class Slot > 1	This is the first class a player switches to.

The second item granter is bound to the second trigger, but grants the weapon when the first class selector switches the player's class.

Leveling Up the Danger

As the player's class level and weapon power increase, the number of creatures and the challenges they present should also increase. To finish off the experience, players have a limited time to fight a guard that poses a considerable threat.

There should also be environmental dangers that teach players where they can and can't go in the game.

Creature Spawner

There are eight Creature Spawner devices in this game. Modify the basic options, then copy and paste the device around your island. Every additional spawner should increase the number of creatures spawned and their difficulty level.

Creature Type	Fiend	Spawns the basic creature type.

Environmental Dangers

Platformer designers use environmental dangers to teach players where they can and can't travel. On this island, environmental challenges are placed in certain areas for players to discover the traps then deduce areas of safe travel.

On the example island, water is a hazard players must avoid. Moving prop rocks provide a way for players to travel over the water safely.

You can change the environmental danger to fire, ice, or any other element that you want to use as a challenge.

Affects Creatures	False	Creatures are not affected by the Damage Volume.
Affects Guards	False	Guards are not affected by the Damage Volume.

Prop Mover

Prop Mover devices are used to create safe travel for players by moving rocks over the water. Make sure the Prop Mover's blue arrow points in the direction you want the prop to move.

Distances props move are measured in meters.

Distance	10.0	The rock moves 10 meters.
