ds_map_find_value(id, key)
| Argument | Description |
|---|---|
| id | The id of the map to use. |
| key | The key to find. |
Returns: Real, string or undefined
With this function you can get the value from a specified key.
The input values of the function are the (previously created)
ds_map to use and the key to check for.
NOTE: If no such key exists then the function will return
<undefined>. You should always check this using the
is_undefined()
function.
amount = ds_map_find_value(inventory, "food");
Or, using the map accessor "?":
amount = inventory[? "food"];
The above code will get the value of the key "food" and store it
in the variable "amount".
