Succeeds if the component is currently simulating.

After OnBeginSimulation is called this call succeeds.
After OnEndSimulation is called this call fails.

Parameters

IsSimulating does not take any parameters.

Attributes and Effects

The following attributes and effects determine how IsSimulating behaves and how you can use it in your programs. For the complete list of attribute and effect specifiers, see the Specifiers Page.

Attribute	Meaning
`native`	Indicates that the definition details of the element are implemented in C++. Verse definitions with the `native` specifier auto-generate C++ definitions that a developer can then fill out its implementation. You can use this specifier on classes, interfaces, enums, methods, and data.
`final`	You can only use the final specifier on classes and members of classes. When a class has the final specifier, you cannot create a subclass of the class. When a field has the final specifier, you cannot override the field in a subclass. When a method has the final specifier, you cannot override the method in a subclass.
`public`	The identifier is universally accessible. You can use this on modules, classes, interfaces, structs, enums, methods, and data.

Effect	Meaning
`transacts`	This effect indicates that any actions performed by the function can be rolled back. The transacts effect is required any time a mutable variable (`var`) is written. You’ll be notified when you compile your code if the `transacts` effect was added to a function that can’t be rolled back. Note that this check is not done for functions with the `native` specifier.
`decides`	Indicates that the function can fail, and that calling this function is a failable expression. Function definitions with the `decides` effect must also have the `transacts` effect, which means the actions performed by this function can be rolled back (as if the actions were never performed), if there’s a failure anywhere in the function.
