===Collision===
There are 3 different colliders: box, cylinder and hull.

====Box====
The box collision will create a box surrounding your mesh. 
{| class="wikitable"
|Example box values
|Result
|-
|"box": { "x": 1, "y": 2, "z": 3 }
|Creates a box collision with the dimensions corresponding to the values of x, y, z.
|}

====Cylinder====
A cylinder collision is good to use for wheels or round objects.
{| class="wikitable"
|Example cylinder values
|Result
|-
|"cylinder": { "diameter": 7, "depth": 1, "margin": 0.5, "axis": "Z" }
|Diameter is the size of the cylinder. Depth sets the thickness. Margin sets the bevel amount, pretty much rounds the edges. Axis determines in which direction the cylinder is facing.

====Hull====
[[File:Hull Collision.png|left|thumb|387x387px]]
A hull collision is a collision mesh in which you can apply to your part by adding it to the part in the parts list by right clicking on it, once you have the hull added you can add a "col" which defines it's collision mesh, it must use the format ".obj" in order for it to work correctly, once you have assigned the mesh, the 3 coordinates which are in the base hull represent the size of the box in which you can weld, or use to place the part down/placing on it.





The hull collision also supports the sticky, and rotation set modifiers.

==== Hull [Old/Pre-Survival] ====
A hull collision is created using a pointlist. It draws lines between vertex coordinates. These vertex coordinates can be found, if for example you open a .obj file with a text editor. However it's good to make a simplified mesh to not get too many coordinates in the list.
{| class="wikitable"
|Example hull values
|Result
|-
|"hull": {

"x": 1, "y": 1, "z": 1,

"pointList": [

{ "x": 1.0, "y": -1.0, "z": -1.0 },

{ "x": -1.0, "y": -1.0, "z": -1.0 },

{ "x": -1.0, "y": -1.0, "z": 1.0 },

{ "x": 1.0, "y": -1.0, "z": 1.0 }

]

}
|x, y, and z defines the size of a space/cube which the pointlist will fit itself in

Each row in the pointList of x, y, z refers to the location of a single vertex point. Together the rows create the hitbox.
