Reference to a function in an object.
In GDScript, functions are not first-class objects. 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 @GDScript.funcref function, a reference to a function in a given object can be created, passed around and called.
Variant | call_func ( ... ) vararg |
Variant | call_funcv ( Array arg_array ) |
bool | is_valid ( ) const |
void | set_function ( String name ) |
void | set_instance ( Object instance ) |
Calls the referenced function previously set by set_function or @GDScript.funcref.
Calls the referenced function previously set by set_function or @GDScript.funcref. Contrarily to call_func, this method does not support a variable number of arguments but expects all parameters to be passed via a single Array.
Returns whether the object still exists and has the function assigned.
The name of the referenced function to call on the object, without parentheses or any parameters.
The object containing the referenced function. This object must be of a type actually inheriting from Object, not a built-in type such as int, Vector2 or Dictionary.
