== Properties ==
=== collision_box ===
'''Type: [[Types/AABBbox]]

Specification of the entity collision boundaries.
When not specified the entity will not have any collision box. (used for smoke, projectiles, particles, explosions etc)
    collision_box = {{-0.4, -0.4}, {0.4, 0.4}}
Note that the {0,0} coordinate in the collision box will match the entity position.
It should be near the center of the collision box, to keep correct entity drawing order.
Note, that for buildings, it is custom to leave 0.1 wide border between the edge of the tile and the edge of the building, this
lets the player move between the building and electric poles/inserters etc. and prevents stucked items on transport belt in some special casese (curves around the corner etc).
=== selection_box ===
'''Type''': [[Types/AABBbox]]

Specification of the entity selection area.
When not specified, the entity will have no selection area (and thus is not selectable).
    selection_box = {{-0.5, -0.5}, {0.5, 0.5}}
The selection box is usualy little bit bigger than the collision box, for tilable entities (like buildings) it should match the tile size of the building.
=== drawing_box ===
'''Type''': [[Types/AABBbox]]

Specification of space needed to see the whole entity.
Default value used is the selection_box.
This is used to calculate the correct zoom and positioning in the entity info gui, when not set, the default value (selection box) is used, and it is usually working well.
    drawing_box = {{-0.5, -0.5}, {0.5, 0.5}}
=== sticker_box ===
'''Type''': [[Types/AABBbox]]

Used to set the area of the entity that can have stickers on it, currently only used for units to specify the area where the green slow down stickers can appear.
It is optional and the collision box is used when not specified.
   sticker_box = {{-0.5, -0.5}, {0.5, 0.5}}
=== weight ===
'''Type''': [[Types/float]]
Weight of the entity used for some physics calculation when car hits something.
    weight = 1
=== flags ===
'''Type''': [[Types/Flags]]

=== minable ===
'''Type''': [[Types/MinableProperties]]

=== emissions_per_tick ===
'''Type''': [[Types/double]]

=== fast_replacable_group ===
'''Type''': [[Types/string]]

=== tile_width ===
'''Type''': [[Types/unsigned]]

=== tile_height ===
'''Type''': [[Types/unsigned]]

=== autoplace ===
'''Type''': [[Types/AutoplaceSpecification]]
