All Implemented Interfaces:

app.rive.runtime.kotlin.core.PlayableInstance , app.rive.runtime.kotlin.core.RefCount
```
public final class StateMachineInstance
extends NativeObject implements PlayableInstance
                    
```
The StateMachineInstance is a helper to wrap common operations to play a state machine.
This object has a counterpart in C++, which implements a lot of functionality. The unsafeCppPointer keeps track of this relationship.
Use this to keep track of a state machine's current state and progress, and to help apply changes that the state machine makes to components in an Artboard.

Constructor Detail

StateMachineInstance

StateMachineInstance(Long unsafeCppPointer, ReentrantLock lock)

Method Detail

getName
```
 String getName()
```

getLayerCount
```
 final Integer getLayerCount()
```

getViewModelInstance
```
 final ViewModelInstance getViewModelInstance()
```
The ViewModelInstance assigned to this artboard. Once assigned, modifications to the. properties of the instance will be reflected in the bindings of this state machine.
Assigning will apply to both the StateMachineInstance and the parent Artboard. Assigning null will do nothing.

setViewModelInstance

 final Unit setViewModelInstance(ViewModelInstance viewModelInstance)

getInputCount
```
 final Integer getInputCount()
```

getInputs
```
 final List<SMIInput> getInputs()
```

getInputNames
```
 final List<String> getInputNames()
```

getStatesChanged

 final List<LayerState> getStatesChanged()

getEventsReported

 final List<RiveEvent> getEventsReported()

getHasCppObject
```
 final Boolean getHasCppObject()
```

getRefs
```
 final AtomicInteger getRefs()
```

setRefs

 final Unit setRefs(AtomicInteger refs)

getCppPointer
```
 final Long getCppPointer()
```

setCppPointer

 final Unit setCppPointer(Long cppPointer)

getDependencies
```
 final List<RefCount> getDependencies()
```

getRefCount
```
 Integer getRefCount()
```

cppDelete
```
 Unit cppDelete(Long pointer)
```

receiveViewModelInstance

 final ViewModelInstance receiveViewModelInstance(ViewModelInstance.Transfer transfer)

advance
```
 final Boolean advance(Float elapsed)
```
Advance the state machine.

Parameters:

elapsed - The time in seconds to advance by.

pointerDown

 final <ERROR CLASS> pointerDown(Integer pointerID, Float x, Float y)

pointerUp

 final <ERROR CLASS> pointerUp(Integer pointerID, Float x, Float y)

pointerMove

 final <ERROR CLASS> pointerMove(Integer pointerID, Float x, Float y)

pointerExit

 final <ERROR CLASS> pointerExit(Integer pointerID, Float x, Float y)

input
```
 final SMIInput input(Integer index)
```
Get the input instance at a given index in the state machine.
This starts at 0.

input
```
 final SMIInput input(String name)
```
Get the input with a given name in the state machine.

stateChanged
```
 final LayerState stateChanged(Integer index)
```
Get a specific state changed in the last advance.

Parameters:

index - The index of the state.

eventAt
```
 final RiveEvent eventAt(Integer index)
```
Get a specific event fired in the last advance.

Parameters:

index - The index of the event.
