Empyrion is a block based game, much like Minecraft; however, it has its own twist, featuring organic voxel-based* planets, moons and more. Blocks are arranged around a structure, formed initially by a 'starter' block, but this structure can be in any position or orientation in the world. This structure then has its own grid in which the player can place blocks. Once a block occupies a location on this grid, no other can be placed in the same spot. These blocks can be rotated in order to face in any direction using the rotation keys (Default: HOME, END) and the axis-control keys (Default: INSERT, DELETE).
Blocks in Empyrion Galactic Survival come in two forms: large and small. Large blocks in game measure 2m X 2m X 2m, and are used for Bases and Capital Vessels, whereas small blocks are 1/4 of that, measuring 0.5m X 0.5m X 0.5m, and are used for Small Vessels and Hover Vessels.
Some blocks will take up multiple portions of the grid. This will be denoted in the Size tag of the item when hovered over.
When the shape changer is opened on a block (Default: RMB), the player can pick a shape for the block to be in when placed. This shape may have different dimensions, hit points, masses, etc., which will all be shown when hovered over while in the shape changer.
Every block has a specific amount of hit points, which, upon reaching 0, will cause the destruction of the block. These can be viewed by holding your multi-tool in your hand and placing the block in your cross-hair. As the block takes more damage, it will change shape slightly in order to provide a visual cue to the player.
A block can be repaired by switching a multi-tool to Repair Mode (Default: RMB), placing the block in your cross-hair whilst in range, then 'firing' upon it, slowly increasing the hit points until they have reached maximum.
When a block is destroyed, it will disappear and drop any of its contents. Some blocks will also explode when destroyed by a weapon, damaging and likely destroying those immediately around them. If multiple of these blocks are placed in a row, then they are at risk of a chain reaction if one of them is destroyed.
Texture & Color
All blocks can be colored, and most can be textured. To do so, one must fire either the color tool or the texture tool at the block/face that one wishes to change. Some will apply to the entire block, such as to a thruster or a spotlight, but others (usually blocks such as Carbon Composite Blocks) can be textured or colored on 6 different faces (but never more).
