Creating Gameplay and Other Behaviors with Script Canvas
Script Canvas is a general purpose, visual scripting environment for Open 3D Engine (O3DE) that you can use to create runtime logic and scripted behaviors for any entity. Script Canvas offers an approachable yet powerful environment to author behaviors using the same framework as Lua and C++. You can use Script Canvas to create scripts for game logic without needing to know how to code, and take advantage of O3DE messaging systems to produce small, event-driven scripts that don’t require complex logic to maintain states.
Script Canvas is an extensible system. You can build your own reusable Script Canvas functions from within the Script Canvas Editor, and use Script Canvas nodes that are created automatically from functionality exposed through the behavior context. The behavior context reflects runtime code, making it accessible to scripts by providing bindings to C++ classes, methods, properties, constants, and enums. The behavior context also provides bindings for O3DE’s AZ::Event and EBus messaging systems, giving you the ability to use Script Canvas nodes to dispatch and handle messages and events.
To extend Script Canvas even further, you can create your own custom nodes (“nodeables”) using the powerful automatic generation capabilities of the AzAutoGen system.
The ease of use of this visual scripting environment does not come at the cost of performance when compared to the more traditional Lua model. To maintain similar performance, Script Canvas graphs are translated by the Asset Processor to optimized Lua script.
To use Script Canvas in your O3DE project, you must enable the Script Canvas Gem and its dependencies.
