Access data structures + arrays [Game Maker | Basics]
77This basics video tutorial shows you how to access data from structures like ds_list, ds_grid, ds_map or arrays in GameMaker.
The idea is quite simple. You create your own data like a ds list or an array and want to access/read out the value stored in there. Accessors are a shorter way to do that with a specific letter for each data structure. So if you want to access a specifc index of an array you can use the @ letter or for example for the ds_list the | letter. That's it!
