Scenario file

Creation of a Scenario

Each Scenario displayed in the scenario list of the scenario selector is based on a property file located in “sim/config/scenarios”. For an example you can look at the file “tutorial.properties.

Structure of a Property Line

[Key] [‘:’ | ’=’][Associated element]

e.g.: field_height=200.0 ; field_height:200.0

Scenario Properties

Each scenario file must include a set of properties which describes the simulation environment.

Mandatory properties:

• title [String]: The title will be shown in the shortlist of the scenario selector
• short_ description [String]
• description [String]
• field_height [real]
• field_width [real]
• worldboundarywalls [Boolean]: If true a wall around the world will be added
• usedefaults [Boolean] : Highly recommended to set it to true. If false no default properties will be loaded
• loader_type[String]: use SIMPLE_PROPERTY_LOADER
• loader_version[String]

Optional Properties:

• image[String]: path to a screenshot of the scenario

Entities

Entities are summarized in entity groups. Each entities within a group has the same properties (except the position).

Entity Groups

Each entity group gets an ID

e.g.: entitygroups.0.

• groupentitytype[String]: Defines the type of the entities of this group
• groupdecisionunittype [String]:Defines the decision unit type
• numentities [Integer]:the number of entities in this group
• positions.positiontype [String]: RANDOM | LIST
  • RANDOM: the entities will be placed randomly
  • LIST: you have to define positions for each entity
• positions - used if position.positiontyp= LIST
  • positions.0.pos_angle [Real]: orientation in radiant
  • positions.0.pos_x [Integer]: position (top-left is (0/0))
  • positions.0.pos_y [Integer]

Change Default Properties

It is possible to change the default properties of an entity of decision unit by adding on of the following keywords.

• overwriteentitydefaults
• removeentitydefaults
• overwritedecisionunitdefaults
• removedecisionunitdefaults

e.g.: entitygroups.1.overwriteentitydefaults.shape.shape_fresh.image_path=/World/src/resources/images/carrot_grayscale.png

changes the property “shape.shape_fresh.image_path” of entity group 1.
