Brief Description

Member Functions

bool is_valid ( ) const
Variant resume ( Variant arg=NULL )

Description

Calling @GDScript.yield within a function will cause that function to yield and return its current state as an object of this type. The yielded function call can then be resumed later by calling resume on this state object.

Member Function Description

  • bool is_valid ( ) const

Check whether the function call may be resumed. This is not the case if the function state was already resumed.

Resume execution of the yielded function call.

If handed an argument, return the argument from the @GDScript.yield call in the yielded function call. You can pass e.g. an Array to hand multiple arguments.

This function returns what the resumed function call returns, possibly another function state if yielded again.
