SkookumScript is a text-based programming language for creating performance-critical, real-time gameplay. It comes with a powerful tool suite and command console that radically changes your workflow in any stage of development. This is done by allowing you to run code snippets to query and manipulate any UE4 game as it runs on a desktop, console or mobile. This includes projects that aren’t coded in SkookumScript. Read more about it here.

Updates to SkookumScript

Coroutines can now be placed in your Blueprint graph and kicked off from within your network!

Coroutines are at the core of SkookumScript and extremely important for time-based flow control, and the update makes it even easier to use them in conjunction with Unreal blueprints.

&raw data members let you use blueprint variables just like standard SkookumScript variable syntax.

Auto-exposed blueprint classes and blueprint variables can be used just like with any other SkookumScript class or data member. All engine-class properties for class Actor are data member variables now.

More Features

Raw data member annotation allows native access to Blueprint variables, as well as other variables stored in engine objects (such as Actor or World objects). For example, if you create a Blueprint variable named Wing Color, it is automatically declared for you in SkookumScript as @wing_color and you can read it and assign to it as you would to any other SkookumScript variable

SkookumScriptGenerator now generates &raw data members for UObject properties (and no longer exports setters and getters)

auto-generation of a SkookumScript class for each Blueprint in a project: the plugin generates an overlay Project-Generated with raw data member information for each Blueprint class. For example, if you create a Blueprint named Hero, a SkookumScript class Hero will be instantly created, ready for you to add your Hero-specific methods and coroutines

when you rename a Blueprint, its corresponding SkookumScript class is automatically renamed; when you delete a Blueprint, its corresponding SkookumScript class is automatically deleted

SkookumScript methods and coroutines are now exposed to Blueprint event graphs via &blueprintannotation. By placing a &blueprint annotation in front of the parameter declaration of the method or coroutine you want to expose, you now have full control over which functions and events you want to have available for placement in a Blueprint event graph

exposed SkookumScript methods and coroutines now appear with fully qualified names in the Blueprint event graph

Blueprint-exposed methods and coroutines can be placed in any SkookumScript class you wish (well, any class related to the class of your Blueprint, such as a super class, the Blueprint class itself, or classes that derive from it). In previous releases this was only available for UE4 engine classes.

coroutines can now be exposed to Blueprint event graphs. When a function node is executed in your graph, its associated coroutine is started. (The old way of method and coroutine invocation via the SkookumScript component has been removed)

SkookumScript IDE button in the level editor that brings up the SkookumScript IDE (and launches and connects or reconnects runtime to the IDE as needed)

SkookumScript button on the Blueprint editor toolbar (UE4.9 and up) that detects the currently selected node and instructs IDE to browse to it if a SkookumScript-equivalent method or coroutine exists

faster launch

on-demand SkookumScript compiled binary reloading when changes are made to Blueprints that affect the SkookumScript class hierarchy
