The "ds_struct_find_first" Function
|struct||The struct to check|
Returns the name of the first key in the given struct, as a string. Further searches can then be performed with
If the struct is empty,
undefined will be returned instead.
Note that because structs are a non-ordered data format, data may be returned in a different order than originally declared in code. Changes to the struct may also change the order in which data is returned with this function.
var key = ds_struct_find_first(my_struct);
var val = true;
variable_struct_set(my_struct, key, val);
