You will notice that the array has been initialised backwards, with the last value being defined first. This simple code will initialize a ten-slot array (from 0 to 9) to hold 0, ie: each slot in the array contains the value 0. This is important to remember as it means that you have to do a certain amount of planning before using arrays, but it is easy enough to initialize one using a repeat loop like this: Initializing an array just means that we give each slot of the array an initial value in preparation for it to be used elsewhere in the project code. We've shown how to check an array for data, but how do we create the array to start with? First it has to be initialized before we can use it or GameMaker will give us an error. It's worth noting that the contents of an array always start at 0 and can never be negative ! Creating Arrays So essentially, an array is a container with a number of slots to store values, and each position in the container has a specific number to identify it, which is what we put in the. If you did the following:Īs you can see, you give the array a variable name and then a value in square brackets, where the value is the position in the array to get the data from. The above code gets the value from position 0 of the array " a" then outputs it to the console, which - based on the contents of the array shown in the image above - would output 125. To access the array you would do something like the following: This is called a 1D (one-dimensional) array, and as you can see the array is stored in the variable " a" and contains multiple values. The image below shows a schematic for a basic array: An array is simply a data type that is assigned to a variable, and it can contain not just one value, but multiple values. "GML is a lot easier to learn than other programming languages.Before going any further let's clarify what an array actually is and how it's structured. It gave me an approachable way to get into game dev and realise my ideas, that I otherwise couldn't have." ![]() ![]() "Honestly, without GameMaker, I probably wouldn't even have gotten to the hobby stage of game development. The GameMaker community is also vast and there's tons of content in forums and tutorials, which made the learning process a lot less scary." It was my very first coding experience and I'm glad I stuck with it. "Everything I know about programming I learned thanks to GameMaker. "GameMaker basically taught me how to make games." ![]() It was the perfect stepping stone for me to go from knowing nothing to feeling like I am an experienced games programmer.” “Using GameMaker's in-built tools let me understand the role they play in game development and gave me the foundations I needed to go on to recreate any of them for myself in larger contexts. "GameMaker's systems were easy enough to approach as a novice and are now so second-nature to me that I'm comfortable tackling larger-scale problems that I wouldn't have dreamt of four years ago." With GameMaker, making games is not only simple, but also fun." "It's easy to pick up and start learning. I still like GameMaker today, as a full time developer, just because it has all the tools I need to make the games." "I’m impressed with how well GameMaker scales when you start out - from knowing nothing to getting familiar with it.
