In 7 Days to Die, torches and candles are a source of light, but they also produce heat. This heat is generated through the game's heatmap mechanic, which controls the spawn of zombies depending on the player's activities. While the heat generated by torches and candles is not related to temperature, it does attract zombies, which can be problematic for players. The amount of heat generated depends on the number of torches and candles, with more items resulting in higher heat levels. Players can remove or modify the heatmap values for torches and candles by editing certain game files.

What You'll Learn
Torches and candles produce a lot of heat
In the 7 Days to Die video game, torches and candles do produce heat. However, it is important to clarify that "heat" in this context does not refer to temperature, but rather to a mechanic in the game called the "Heatmap." The Heatmap measures the activity level in a given area, and higher activity levels will attract zombies.
Torches and candles are considered flickering fires in the game, and these items do affect the Heatmap. When placed by the player (not as part of a prefab), they generate heat events. However, they do not emit heat in line with an interval like other sources of heat. Instead, they generate heat events simultaneously every real-world minute, or every 666 ticks. This behaviour is likely for performance reasons.
The amount of heat generated by torches and candles depends on the game settings. In the default setting of 60 minutes per day, one torch generates 0.5% heat every minute in real-world time. So, if you put up 10 torches, they would generate 100% heat after 20 minutes. However, if the default setting is changed to 120 minutes per day, one torch would only generate 0.25% heat, and 10 torches would need 40 minutes to reach 100% heat.
It is worth noting that there are two types of torches in the game: wallTorchPlayer and wallTorch. Only the wallTorchPlayer generates heat. Additionally, candles emit half the amount of heat as torches and burning barrels. So, if you want to avoid attracting too many zombies to your base, candles are a better option for light.
Some players have found the heat generated by torches and candles to be excessive and have chosen to modify their games to reduce the heat generated by these items or remove their heatmap impact altogether.

Electric lights are an alternative
In the 7 Days to Die game, torches and candles are a source of light, but they also produce a lot of heat. This heat is generated by the torch or candle every minute in real-time, and it can attract zombies towards the player.
Some players have noted that they prefer the aesthetic of candles and torches, but they use electric lights when they are in a hurry. Additionally, electric lights were available in a15 without the need to make electricity.
Players can also remove the heatmap from candles and torches by opening the blocks.xml file and removing the lines that reference the heat map (HeatMapStrength, HeatMapTime, and HeatMapFrequency). However, this is not recommended as it can cause issues with the game's mechanics.
Overall, electric lights are a viable alternative to torches and candles in 7 Days to Die, as they provide light without generating the same amount of heat and attracting zombies.

Heatmap mechanics control zombie spawns
Heatmap mechanics play a crucial role in controlling zombie spawns in 7 Days to Die. While it does not directly influence temperature, the heatmap level represents the activity level in a given area, and higher activity leads to increased heatmap values. This, in turn, results in more zombies spawning nearby.
The heatmap is divided into chunks, which are 16x16 block areas, and each chunk has a unique heat level. Various activities can increase the heat level in a chunk, including using the forge, chopping down trees, and mining. These activities not only affect the chunk where they occur but also adjacent chunks. Once the activity stops, the heat level gradually decreases over time.
To manage the heatmap effectively, players should consider the following strategies:
- Limit Object Concentration: Avoid placing too many heat-emitting objects close to each other, especially inside the main base. Distribute them across separate chunks to manage heat efficiently.
- Timed Utilization: Instead of keeping heat-generating objects operational all the time, schedule periods of intense usage for short durations.
- Monitor Noise Generation: Noise contributes to the heat level, so opt for quieter alternatives when possible. For example, use suppressed weaponry and less disruptive farming methods.
- Defensive Planning: Design defensive layouts that include chokepoints, traps, and barriers to control zombie movement and protect vital infrastructure.
- Prioritize Essential Tasks: Focus on acquiring necessary equipment early in the game to reduce the need for heat-intensive devices later on.
Additionally, players should be aware of the different types of torches and candles, as some generate more heat than others. For example, the wallTorchPlayer torch generates heat, while the wallTorch does not. Similarly, candles emit half the amount of heat as burning barrels and torches. Therefore, using candles for light can help reduce the heat level and attract fewer zombies.
By understanding the heatmap mechanics and implementing these strategies, players can better control zombie spawns and improve their chances of survival in 7 Days to Die.

Heatmap values can be modified
In 7 Days to Die, the heatmap is a crucial game mechanic that controls the spawn of zombies depending on the player's activities. Heatmap values can be modified by adjusting the settings and placement of various in-game items, such as torches and candles.
Torches and candles are known to produce a significant amount of heat, which can attract zombies and increase the likelihood of encounters. However, players have the option to modify the heatmap values associated with these items to better suit their gameplay preferences. For example, players can change the tick rate and heat values of torches and candles to reduce their heat output. This can be done by accessing the blocks.xml file and adjusting the HeatMapStrength, HeatMapTime, and HeatMapFrequency values for candles and torches.
Additionally, players can choose to use different types of torches, as only the wallTorchPlayer variant generates heat. Prefab torches, for instance, have no effect on the heatmap. Similarly, candles emit half the amount of heat as burning barrels and torches, so players can opt for candles to reduce heat generation while still having a source of light.
It is worth noting that while modifying heatmap values can provide advantages, it may also impact the gameplay experience. For instance, reducing the heat output of torches and candles can decrease the frequency of zombie encounters, making the game less challenging. Players should consider their preferences and the potential consequences when deciding to modify heatmap values.

Heatmap values depend on game settings
In the 7 Days to Die game, the heatmap is a crucial mechanism that controls the spawning of zombies, depending on the player's activities. While the heatmap does not have a literal implication towards temperature, it does affect a certain area around the affected zone. It can be interpreted as a measurement of the activity level in a given area. The higher the activity level, the more likely zombies will appear.
The heatmap values do depend on the game settings, specifically the default setting of 60 minutes per day. At this setting, one torch generates 0.5% heat every minute in real-time, and one candle generates half the amount of heat of a torch. So, if you put up 10 torches, after 20 minutes it would generate 100% heat. However, if the default setting is changed to 120 minutes per day, one torch would only generate 0.25% heat, and 10 torches will need 40 minutes in real-time to reach 100% heat.
The number of ticks is also a factor in the heatmap values. Ticks are a unit that each block uses to calculate the time between each heat event and its duration. In the 7D2D world, 1000 ticks equal 1 hour of in-game time. So, the duration of a tick in real time depends on the game settings. If it's at the default setting of 60 minutes per day, one tick equals 3.75 seconds.
Additionally, the frequency of heat events is important to consider. Flickering fires, such as torches, candles, and burning barrels, generate heat events every minute in real time. This is different from other sources of heat events from blocks, which emit heat at an interval. The more frequent the heat events, the higher the heatmap value will be.
It's worth noting that there are two types of torches: wallTorchPlayer and wallTorch. Only the wallTorchPlayer generates heat and affects the heatmap.
