This function returns the last key stored in the ds_map. This is not the last key in the order that you have added them! Ds_maps are not stored in a linear form, for that use ds_lists, so all this does is find the last key as stored by the computer. This can be useful if your have to iterate through the ds_map looking for something, but should be avoided if possible as it can be slow.
|id||The id of the map to use.|
Real or String
var size, key, i;
size = ds_map_size(inventory);
key = ds_map_find_last(inventory);
for (i = size; i > 0; i--;)
if key != "gold" key = ds_map_find_previous(inventory, key) else break;
The above code creates some temporary variables and then gets the ds_map size and finds the last key as stored by the computer in the map. It then uses a for loop to iterate back through the ds_map looking for the key value "gold". If it finds it, it breaks out the loop.
