With this function you can check the weak reference to a struct to see if it is still "alive" or not. You supply the weak reference to check (as returned by the function weak_ref_create()), and the function will return true if the struct is still being referenced somewhere or false if it's not and has been garbage collected. Note that if you supply a value that is not a weak reference, the function will return undefined.
weak_ref_alive(weak_ref);
| Argument | Type | Description |
|---|---|---|
| weak_ref | Struct Weak Reference | The weak reference to the struct you want to check. |
Boolean (or undefined)
if (weak_ref_alive(inventory_ref))
{
inventory = -1;
}
The above code checks a weak reference to a struct and if it is still alive the variable referencing it is set to -1, de-referencing the struct and enabling it to be garbage collected.
