Feature Spotlight – Temperature & Weather System


Sweater? Check. Sandals? Um… check? Umbrella?! Where are we going that we will need all these items? Now that the temperature and weather system has been released, players will need to adapt to the game’s ever-changing landscape at a moment’s notice.

In Fractured Online, temperatures vary depending on 3 main factors:

  • World Biome
  • Time of day
  • Weather

The Fractured Online world is vast and diverse. Different biomes come with many unique features, including different temperature ranges. A biome’s temperature range is defined by a temperature/time curve that dictates the temperature variation of a biome during the day/night cycle.

The combination of biome and time of day defines its base temperature at any given time, which can then be altered further by different weather events, either in a positive or negative direction, depending on the event.

Temperatures aren’t implemented just to add a bit of spice to Fractured Online, but instead, they can influence the gameplay. More or less extreme temperatures may force the player to prepare differently before venturing into the world.

Generally speaking, venturing unprepared in a very cold climate may trigger the “Chilled” status effect on the player. Alternatively, venturing in a very hot climate may trigger the “Warm” effect. The “Frozen” and “Burning” effects, which usually occur respectively at 100 Chilled and Warm stacks, are never triggered by the temperature alone.

Different character races have different tolerance thresholds to temperatures, which can be further modified by worn equipment, abilities, and potions (potions will be added once alchemy is introduced in a future update).

To briefly explain the system, we will consider what happens when the temperature gets too cold and how it can be prevented.

  • The system is symmetrical for hot temperatures.
  • Each player has a minimum temperature tolerance, which solely depends on its race.
  • Whenever the temperature goes below the minimum temperature tolerance, the player is out of its comfort zone, and starts getting Chilled. Stacks are added at a rate of 1 stack every 10 seconds (the Chilled effect can have up to 100 stacks).
  • Stacks gained this way don’t decay over time (as they usually do).
  • The maximum number of stacks depends on how cold it is: for each 1°C below the minimum threshold, the maximum number of stacks increases by 10.

Let’s give an example:

  • Your minimum temperature tolerance is 5°C. The temperature is 0°. You currently have 0 Chilled stacks.
  • You start gaining Chilled stacks at a rate of 1 stack every 10 seconds, until you reach 50 stacks, since the temperature if 5°C lower than your tolerance (5×10 = 50).
  • If you travel to a slightly warmer area, let’s say 3°C, your 50 Chilled stacks will start decaying normally, until you reach 20 stacks, since you are still 2°C lower than your tolerance.

Finally, Chilled and Warm status effects are not exclusive to the temperature system. They can also be triggered by other outside influences, like player spells, and are countered by each other (chilled counters warm and vice-versa). Variations in the amount of Chilled and Warm stacks caused by external factors happen normally and are not influenced by the world temperature.

Returning to the example above:

  • You are now at 0°C and with 50 Chilled stacks. In these conditions, your stacks won’t decay nor increase.
  • Let’s say that a Fireball spell, among other effects, adds 50 Warm stacks to anyone hit by it. You are hit by a Fireball. Since you already had 50 Chilled stacks and each Warm stack removes 2 Chilled stacks, 25 of the 50 Warm stacks are consumed to remove all 50 Chilled stacks. The remaining 25 Warm stacks are added to you, so you end up with 0 Chilled stacks and 25 Warm stacks after being hit by that Fireball.
  • Now you are still at 0°C, which means you gain a Chilled stack every 10 seconds, up to 50. Similarly, to the effect of the Warm stacks on the Chilled stacks, whenever you would have gained a Chilled stack while under the Warm effect, you end up losing 2 Warm stacks instead.

It’s worth noting that Chilled and Warm stacks gained due to the temperature are added on a much slower pace than stacks gained from spells (1 stack every 10 seconds, as stated above). Spells always add 10+ stacks of either effect per hit and each stack decays in 0.1 seconds. This means that in extreme situations, a player may decide to hit himself with Fire or Ice based spells periodically to counter extreme temperatures.

A more orthodox way to counter extreme temperatures would be to wear adequate equipment. Most pieces of equipment come with a couple of special properties called “Heat Insulation” and “Cold Insulation.” Each property increases the player’s tolerance towards extremely hot and cold environments additively (NOTE: properties may also decrease tolerance if they are negative).

The table below shows an example of the effects of different pieces of armour to the base temperature tolerances of a player:

Some crafting materials also come with Heat and Cold Insulation properties, which are directly added to the final piece of equipment base values crafted with them.

Some spells like “Protection from Fire” and “Protection from Cold” grant you immunity to the Chilled and Warm status effects, which in turn may provide immunity to extreme temperature effects, at the cost of one ability slot and some mana/second to keep them active.

Potions that alter your temperature tolerances will also be added in the future.

In Fractured Online, the weather is determined by a dynamic system of circular clouds that can spawn in different zones within a continent.

Each cloud has its own life cycle: first it grows, gradually darkening the sun, then if it has a precipitation event assigned, it starts precipitating (rain, hail, snow, etc..) and gradually shrinking in size, and finally, as it reaches a smaller pre-determined size, it stops precipitating and starts dissipating completely.

Each cloud determines a specific weather event, and during its lifetime it determines the precipitation particle type, the wind intensity and turbulence, other special effects like lightning, and the temperature variation.

Each cloud, as stated above, is circular, and affects anyone within its range, which means that it’s possible for a player to enter a cloud while venturing in the world. Weather events in Fractured are not continent-based, but location-based!

All the effects of a cloud are interpolated depending on the distance from the center of the cloud. That means everything will be more intense in the middle and less intense at the borders of the cloud so that players will experience a gradual variation of the weather while entering a cloud zone.

Although quite rare, two or more clouds could potentially overlap, in which case the player will experience a mix of the effects from both clouds, weighted depending on the intensity of each cloud in that specific position and normalized between the two.

Each continent has different pre-determined weather zones with each zone offering a different setup. This determines the chance of a cloud to spawn within is range, the maximum number of clouds existing at once, the size of the clouds, and the type of clouds.

So far, we have 4 types of weather clouds, each one with a low intensity event and a high intensity event:

Cloud Type Low Intensity Event High Intensity Event
Storm Rain Storm
Thunderstorm Rain Thunderstorm
Sleet Storm Rain Sleet Storm
Blizzard Snow Blizzard

Note that not every cloud reaches its highest intensity. For example: a small Storm cloud may only result in a Rain event during its entire life cycle.

Right now, all the cloud types we have deliver a negative effect on the temperature. In the future, things may change as we add special events like firestorms, meteor strikes, acid rain, and other special events!

Please note: only the temperature system is available in the patch released on April 27, while the weather system is set to go live the following week.

It was the Heat of the Moment

As you can see, our temperature & weather system can and will influence each player’s adventure through Fractured Online. Whether it works in their favor or against completely relies on how prepared they are when met with a rainy day.

Bug Fixes

The update doesn’t only bring a new system to life, but plenty of bug fixes as well.
