Changes history - AnyLogic

Version 6

6.2.2

Engine: Fixed error which could occur when inspecting arrayed Flow/Aux/Stock variable in chart mode

IDE & Engine: Several controls (Button, Edit Box, Combo Box, List Box, File Chooser, Progress Bar) now have "Default" background color option instead of "No Fill". Other controls (Check Box, Radio Buttons, Slider) still have "No Fill" option. Some models may need a certain review. Corresponding generated Engine constants are 'controlDefault' and 'transparent', respectively (instead of 'null').

Engine: Fixed bug: After Simulation Run Code wasn't invoked when stopping model from a paused state

Code generation: It is possible now to populate replicated embedded objects with new elements created using custom parameter values defined as arguments to the new method like add_myReplicatedEO(Type1 param1,...) (where myReplicatedEO is replicated embedded object and "param1..." are its non-dynamic parameters)

Engine & Code generation: Inspect text of Insert object has been improved: now it includes inserted expressions text

Enterprise Library: Now Source, ResourcePool, and NetworkREsourcePool support associating individual animation shapes with entities and resource units; this is based on new cloning feature of shapes.

Engine: Fixed chart legend appearance under Linux with GNOME UI

Engine: Method setGroup() of ReplicatedShape is no more accessible like in other shapes. Use add() and remove() methods of group

Engine: Added cloning support for all the shapes, except GIS, controls and charts

Engine: Fixed full-screen mode under Linux

IDE: Exporting of stand-alone java applications is enabled in Professional Edition

Engine: Fixed ShapeSlider appearance under Linux with GNOME UI

Engine: Fixed ToolBar and Status bar appearance (items layout) under Linux with GNOME UI

Engine: Fixed error which could occur when stopping model containing Query objects with opened ResultSets

Enterprise Library: Network Based Modeling: Added parameter drawAtRandomPosition to control the way the items are animated when they are at a node (not moving)

Enterprise Library: ResourcePool: now units can optionally be modeled aggregated, i.e. in quantities. This can be used for efficient modeling of large amounts seized and released in blocks.

Engine: Added new method to experiments: getCommandLineArguments()

Engine: Button "AnyLogic" on the model toolbar now works under Mac OS and Linux

6.2.1

Code generation: Fixed generation of URL-based Text Files
Code generation: Fixed code generation of embedded objects with ignored parameters
Code generation: Fixed code generation of invalid empty dimensions and variables with these dimensions

Code generation: Fixed drawing of variable connectors at model run-time
Engine: Fixed immediate rescheduling of condition-based transitions and events with closed guard. Now such events are scheduled again on next model change

Enterprise Library: Entity and resource unit rotation is now off by default as this is most frequent case
Enterprise Library: Fixed Match object that could possibly remove entities from the queues without completing all required operations (e.g. cancelling a timeout, etc)
Enterprise Library: Network Based Modeling: fixed late initialization of network that could sometimes cause unrecognized home paths of NetworkResourcePool objects
Enterprise Library: Network Based Modeling: a moving resource unit released and returning to its home location is now counted as busy (was: idle), therefore utilization statistics is now different
Enterprise Library: Network Based Modeling: significantly improved the user error diagnostic for incorrect topologies of networks
Enterprise Library: Network Based Modeling: Network static resource default animation (a small circle) is now not visible (made transparent by default), this can be changed by the user
Enterprise Library: Network Based Modeling: it is now possible to change the network configuration at any time at runtime: add/remove nodes and segments, etc.; refreshNetwork() method added
Enterprise Library: Network Based Modeling: Network object: added method distanceBetween( rect1, rect2 ) returning the distance between the two network nodes as stored in the routing table
Enterprise Library: The default resource type in NetworkResourcePool is now "Moving"
Enterprise Library: Sink object: added method count() returning the number of entities exited via that Sink
Enterprise Library: Fixed Service object in its release part: previously it could attempt to release a wrong resource in case of dynamic pool and quantity evaluation
Enterprise Library: Now objects with Single animation type will animate not just one, but all items (at the same position)
Enterprise Library: The user can now obtain the position of an entity or resource unit animation, both for regular and network-based animation, see methods getX(), getY(), getAngle(), getPosition()
Enterprise Library: Now you can fine tune the position of the entity animation by using method setOffset(x,y,angle); for example you can position the entity near to the resource unit it has seized and vice versa
Enterprise Library: Fixed animation of Bag type of resource pool, which could previously display only idle units
Examples: Added example Vibrating String to illustrate how you can flexibly work with array indexes in equations
Examples: Added The Game of Life model illustrating AnyLogic support for Agent Based Modeling in Discrete time and Space

Engine: lerpColor function now supports opacity (alpha component) of color
Engine: Method cancel() of Events should not be called by the user and is no longer accessible, reset() method should be called instead. Old models calling "cancel()" on events need some refactoring

If the condition appears to be false (e.g. as a result of execution of a competing simultaneous event), no action is performed. Therefore now {condition evaluation, action execution} may be considered as logically atomic
Engine: Fixed: Event of type Timeout can now be suspended and resumed (previously calling suspend resulted in deactivation of the event)
