Vortex Gaming

· Experiencing base collapse in 7 Days to Die is common, but the game doesn't clearly explain the structural integrity rules.
· Understanding these rules will help you avoid base collapse and build all your bases safely.

· You can stack an infinite number of steel blocks on a single wood frame without it collapsing. This is due to the principle of vertical support.
· Most blocks have a 'Vertical Support: Yes/No' stat. Blocks with 'Yes' can support infinite weight if connected to bedrock.
· Blocks with 'No' (e.g., Dew Collectors) cannot support anything above them.
· If any block in a stack is destroyed, all blocks above it will begin to apply weight to surrounding blocks according to horizontal support rules, potentially leading to collapse.

· Every block has a horizontal support stat and mass.
· For example, a wood frame with 40 horizontal support and 5 mass can horizontally support 8 blocks of its own type.
· For a steel block with 20 mass, a wood frame can only support 2.
· A steel block has 300 horizontal support and can support 15 blocks of its own type.
· Horizontal support is applied independently to each side. Adding too many blocks to one side may cause only that section to collapse, leaving the rest intact.
· Therefore, always be aware of the mass and horizontal support of the blocks you are using.

· You can easily check stability by observing color changes when placing blocks.

Color	Meaning
No Color/White	Stable
Yellow	Consider adding support
Red	High risk of collapse

· When upgrading blocks with a stone axe, block ghosts don't appear, making it hard to gauge mass increase. It's recommended to hold a block in your inventory and hover it over the block you're upgrading to check stability.
· Always add more support than necessary to prevent unexpected collapses.

· If zombies can't find a path to the player, they will attack tall pillars first. Install extra pillars to prepare for base collapse.
· When zombies fall from a height, they enter 'Destroy Zone Mode' and attack the base for about 10 seconds. This mode is disengaged if you damage the zombie, so set up traps on the base floor or prepare means to attack zombies from a firing position.
· Zombies are aware of block HP and prioritize attacking weaker blocks. Therefore, use the strongest blocks for your base's foundation and pillars to prevent zombies from collapsing your base from below.
· Most blocks provide the same mass and horizontal stability regardless of shape. Concrete slabs are essentially the same as concrete blocks. Utilize this to create strong internal supports with smaller blocks, taking up less space.

· It's recommended to experiment with important base designs in a test world beforehand. Create a new world, press F1 to open the console, then type 'DM' (Debug Mode) and 'CM' (Creative Mode).
· In the creative menu, you can spawn as many building materials as you want to experiment freely.
· For horde night tests, you can adjust the time in the pause menu or use the command 'st ' to set a specific time. (e.g., 'st 7000 22 0' sets it to day 7000, 22:00)
· Activate the 'Structural Integrity Visualizer' in the pause menu to check your base's stability by color.

Color	Meaning
Green	Fully Supported
Yellow	Relatively healthy but not fully supported
Orange/Red	Needs more support, high risk of collapse

· This method allows you to plan your base safely and efficiently in the actual game without cheats or disabling achievements.
