Import it into IDE.Īlternatively copy the code from corresponding scripts into your project. Get the latest asset package from the releases page. You can easily encode/decode ArrayList to Json and vice versa with this packages: Weak parts are: slower than pure array or ds_list, no outside of bounds checking and possibility of losing the reference if reassign it explicitly via list.array =, which you shouldn't do. Basically you have all the array scripts ever written for GM available for this struct also. Array reference is staying the same for the all lifecycle of struct so any changes made with that array will also reflects on the ArrayList and other way, if you pass that array somewhere (inside another data structure, draw it on GUI, etc.), all changes made with the ArrayList struct will also change the array. There are some methods, including analogues of corresponding ds_list functions such as: add, remove, insert, sort, shuffle, reverse, copy and other.Īrray reference is available from the struct in the array property and then can be passed anywhere or used with an accessor.

The advantages over ds_list or other struct realizations are: garbage collected, fast sort function, accessor and referencing as an array.ĪrrayList is GC-friendly as it's basically an array inside of a struct so no need to manually destroy it as you do with the ds_list (although you can use delete on a ArrayList to dispose it explicitly). Works only with the 2.3+ version which introduced structs and constructors.

It is a custom List class / struct build on top of a standard GameMaker array.
