Stop the function execution and return the current state. Call [method GDFunctionState.resume] on the state to resume execution. This invalidates the state.
Returns anything that was passed to the resume function call. If passed an object and a signal, the execution is resumed when the object's signal is emmited.

Reference to a function in an object.
</brief_description>
<description>
In GDScript, functions are not [i]first-class objects[/i]. This means it is impossible to store them directly as variables, return them from another function, or pass them as arguments.
However, by creating a [FuncRef] using the [method @GDScript.funcref] function, a reference to a function in a given object can be created, passed around and called.

State of a function call after yielding.

Calling [method @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 [method resume] on this state object.

Resume execution of the yielded function call.
If handed an argument, return the argument from the [method @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.

<class name="InstancePlaceholder" inherits="Node" category="Core">
<brief_description>
Placeholder for the root [Node] of a [PackedScene].
</brief_description>
<description>
Turning on the option [b]Load As Placeholder[/b] for an instanced scene in the editor causes it to be replaced by an InstacePlaceholder when running the game. This makes it possible to delay actually loading the scene until calling [method replace_by_instance]. This is useful to avoid loading large scenes all at once by loading parts of it selectively.
The InstancePlaceholder does not have a transform. This causes any child nodes to be positioned relatively to the Viewport from point (0,0), rather than their parent as displayed in the editor. Replacing the placeholder with a scene with a transform will transform children relatively to their parent again.

<description>
Replace this placeholder by the scene handed as an argument, or the original scene if no argument is given. As for all resources, the scene is loaded only if it's not loaded already. By manually loading the scene beforehand, delays caused by this function can be avoided.
