Numbers in parenthesis represent the
keyboard shortcut. A stadium can have a maximum of 255 of
each type of object.
Select (1)
Click on objects to select them.
Shift-click to select multiple objects.
Click and drag to select multiple objects.
Click and drag on segments to curve them.
Click and drag on selected objects to move them around.
To move segment, first click on it to select it, then
drag its vertices.
Rotate (2)
Click to place the center of rotation.
Click and drag to rotate the selected objects.
Scale (3)
Click to place the center of transformation.
Click and drag to scale or flip the selected objects.
Some types of objects do not scale well. Ideally,
discs and curved segments become oval-shaped when scaled
vertically or horizontally. Haxball does not support
ovals, so their image needs to be approximated.
A scaled disc will have the same area as it's ideal oval.
A curved segment will keep the same tangent on it's first point.
Segments, vertices, planes and goals scale perfectly.
Segment (4) -
A segment connects two vertices. They can be used as decorations or as walls.
Click and drag to create segments.
Click on existing vertices to connect segments to them.
Vertex (5) -
A vertex is a point on the stadium that can have special properties.
Click to place a new vertex.
Disc (6) -
Discs are the only object apart from
the puck and the players that can be made to
move. They can be used as decorations or be allowed to
collide with other objects.
Click to create normal-sized discs.
Click and drag to create custom-sized discs.
Goal (7) -
When the puck crosses a goal, the opposite team scores a point.
Click and drag to place a goal.
Left side goals will start out red, right side goals will start out blue.
Blue players score in the red goal, and vice-versa.
Plane (8) -
Planes are invisible walls of infinite length.
Click to place a plane. The plane will face the
center of the stadium (it will have a negative
dist).
Property Editor
When objects are selected, their common properties
are listed in the properties tab on the bottom left.
When one of these properties is changed, it will be applied to all the selected objects.
When a new object is created, the properties will be applied to it.
Properties
speed - The initial speed of a disc. The default value is 0,0.
bCoef - How much bounce an object
has. Officially, this is a number between 0 and
1. Values below 0 and above 1 can also be used with care
(and haxketball nets). The standard value for walls is
1. The standard value for goal nets is 0.1.
cMask - A list of groups that the object
collides with. The puck and the players have a cMask of
"ball, red, blue, wall". During a red kick-off, all
players have an additional cMask of "redKO". During the blue
kick-off, all players have an additional cMask of "blueKO".
cGroup - The groups that an object belongs to.
ball - the puck
red - red players
blue - blue players
wall - walls
redKO - kick-off barriers for red's kick-off
blueKO - kick-off barriers for blue's kick-off
all - all of the above
trait - A named set of properties common to many objects.
x - The horizontal position of a vertex.
y - The vertical position of a vertex.
curve - The angle (in degrees) at which a
segment curves. Possible values are between -340 and 340.
vis - true or false. Is this object visible?
color - The color of segments and discs. Specified as a 6-character hexidecimal string.
normal - The direction faced by a plane.
dist - The distance of a plane from the
center of the stadium. When it is positive, it keeps
objects away from the center. When it is negative it
keeps object close to the center.
radius - The half-size of a disc.
invMass - The inverse mass of an disc. 0
means that the disc doesn't move. The higher the
invMass, the lighter the disc. Values below 0 are
possible but must be used with care (and bobsleds). The
default for discs is 1.
pos - The x and y coordinates of the center of a disc.
p0 - The coordinates of one end of a goal.
p1 - The coordinates of the other end of a goal.
team - The team whose goal it is, either blue or red.
damping - The deceleration rate of a disc. 1 means no deceleration. The default value is 0.99.

horizontally and vertically to help design symmetrical
stadiums.
Preview Mode - Preview the stadium without any invisible shapes.
Keyboard Shortcuts
Some browser plugins are not compatible with keyboard shortcuts.
Text Mode
The text editor is simpler than notepad in some ways, but has some HBS-specific features.
The code is formatted for easy editing.
Vertexes are annotated with their index number.
Objects selected in the visual editor are marked in the code.
The Import button lets you instantly preview your stadium in the visual editor.
The Goto Character button allows you to quickly find
a position in the file. This can be the position of an
error reported by Haxball.
Stadium Properties
Default Values are in parenthesis.
Spawn Distance - How far to the right and left of the center should the players start?
Height and Width - The half size of the stadium.
Background
Type - The style of backgroud to use, either grass or hockey.
Width and Height - The half size of the background.
Border Radius
Kick-Off Radius
Player Physics
Bounce (0.5), Inverse Mass (0.5) and Damping (0.96) - properties of the player disc when not trying to kick.
Acceleration (0.1) - Acceleration when moving normally.
Kicking Acceleration (0.07) - Acceleration when trying to kick.
Kicking Damping (0.96) - Damping while trying to kick.
Kick Strength (5) - Strength of kicks.
Ball Physics
Radius (10), Bounce (0.5), Inverse Mass (1), Damping (0.99), Color (FFFFFF), Collision Mask (all) and Collision Group (ball) - properties of the ball disc.

HaxBall
HaxBall is an online multiplayer game created by basro.
HBS
HaxBall players can create new stadiums by
writing HaxBall Stadium (HBS) files directlty or using an
editor like this one. basro wrote
a small
tutorial on how to write raw HBS files. New stadium
features released in February 2012 are described in
a second
tutorial.
HBR
HaxBall Recordings are not yet supported by
Nn's HBS Editor. Partial information such as reconstructed
stadiums (in HBS format) can be extracted from HBR files
using HBRDUMP (2Mb zip file).
