SDKInstanceBase interface is used as the base class for runtime instances in the SDK. For "world" type plugins, instances instead derive from SDKWorldInstanceBase which itself derives from
SDKInstanceBase cannot be directly constructed; it should only be used as a base class.
- Reference to the Instance representing this instance in the runtime. This allows access to Construct's built-in runtime features for instances.
- Reference to the associated Runtime that controls execution of the project.
- Reference to the ObjectClass representing the object type that this instance belongs to.
- Reference to your addon's SDK type class, which derives from SDKTypeBase.
- Optional override for when an instance is released.
- Returns your addon's SDK plugin class, which derives from SDKPluginBase.
- Fire a trigger condition. The condition must be declared as a trigger in aces.json. Pass a full reference to the condition method, e.g.
- AddDOMMessageHandler(handler, callback)
- Add a callback to be run to handle a message posted from a DOM-side script. The handler is a string identifier. The callback receives the posted data as an argument. Note that if the caller in the DOM-side script originally used the
PostToRuntimeAsync method, the callback may be an
async function, and the return value is posted back to the DOM-side script. The
AddDOMMessageHandlers variant accepts an array of
[handler, callback] which is convenient when adding multiple handlers.
- PostToDOM(handler, data)
- PostToDOMAsync(handler, data)
- Post a message to a DOM-side script. The handler is a string identifier. The
data must be structurally clonable (since it is posted down a MessageChannel).
The async method returns a promise that resolves with the DOM-side callback's return value. The non-async method does not return a value and the DOM-side callback's return value is discarded (i.e. a "fire and forget" message).
- Utility methods to start or stop the runtime calling the
Tick2() methods of your instance every tick, and also to check whether ticking is active. It is recommended to stop ticking whenever the tick method is no longer needed to reduce the performance overhead of ticking. Redundant calls to start or stop ticking are ignored. The first call always takes effect (i.e. calls do not stack - if you make 3 calls to start ticking then 1 call to stop ticking, ticking is stopped).
- Optional override that is called every tick just before events are run after
_StartTicking() has been called.
- Optional override that is called every tick just after events are run after
_StartTicking2() has been called.
- Override to return properties to display in the debugger. For more information see runtime scripts.
- Optional override to return a JSON object that represents the state of the instance for savegames.
- Optional override accepting a JSON object returned by a prior call to
SaveToJson() that represents the state of an instance to load, for savegames.
- CallAction(actMethod, ...args)
- Convenience method to run an action method with the given parameters. For example:
this.CallAction(C3.Plugins.MyAddon.Acts.MyAction, "foo", "bar")
- CallExpression(expMethod, ...args)
- Convenience method to run an expression method with the given parameters. Returns the value returned by the expression. For example:
const value = this.CallExpression(C3.Plugins.MyAddon.Exps.MyExpression)
- Return a custom class to instantiate for the script interface in Construct's scripting feature. See the SDK downloads for sample usage of a custom script interface.
- Return the actual script interface used for this instance in Construct's scripting feature. This is an IInstance or derivative.
