These variables are the ones initialized with the var keyword. Here, c would store 9 because of the expression a + b (which means 4 + 5 as a is 4 and b is 5). You can also use variables in mathematical expressions… a = 4 There are many ways of assigning a value… price = 4 * 5

So feel free to skip it and focus on the main code.
Side note: It is not required in GML to put a semicolon ( ) after each statement. If the variable has already been initialized before, this serves to change its value to 20. Here we have initialized a variable named price which contains 20 as a value. It’s up to you what you want to name your variables and what you want to store inside them. For example, a variable named player_health may contain 100, or a variable named player_name may contain the player’s name (“Peter”, “Lindsey”, etc.). Variables are containers that contain some value/information.
#GAMEMAKER STUDIO 2 ALARMS CODE#
That event will only run when the instance running the code collides with any instance of the object specified while creating the collision event. While adding a collision event, you can select an object to create the event. So if I set Alarm 0 to 60 in the Create event, the code inside the Alarm 0 event will run after 60 steps. AlarmsĪlarm events run after you set them. The Draw event overrides the default draw of the instance, meaning your instance won’t be drawn unless you use draw_self(). For example, functions like draw_sprite, which is used to draw a sprite at a location, or draw_rectangle, which is used to draw a rectangle, only work in the Draw event. This event is used to execute the draw codes. This is used for things you want to keep on happening. The most important and the most used event – the Step event runs every step – if your game/room speed is set to 30, a Step event will run 30 times in a second. Here you can initialize most of the stuff related to your instance. Here’s a quick introduction to the events we’ll be using the most: CreateĬode inside the Create event is executed only once: when the instance running the code is first created. There are a lot of events to choose from in GameMaker. You put code inside an event, and when that code runs depends on the type of event you put it in. Kudos if you can read it all in one go!Ĭlick here to read the Russian translation of this guide, by Artem Darkov. After this tutorial, you’ll be able to use GML to build your own games effectively!īookmark this page now ( Press CTRL + D) as this guide is quite long and you will need to close it and come back later. It will introduce you to the basics of programming and how GML works. So yeah, this doesn't really disable the event but just aborts it until the next call.Welcome! This tutorial is aimed at beginners who have little to no experience in GML or programming in general. Which would be called for seconds 1-5 and then again after 11.
If(executed_seconds > 5 & executed_seconds < 10) Additionally, there are built-in variables you can use to check the time that has passed since the code was started, namely "executed_seconds", "executed_frames" and "executed_times" (how often your code was called).
So it's not fully disabled, just skipped at this frame. Which basically aborts the execution until the next frame. At the moment, you could do something like: execute every frame So you basically want the ability (from inside and outside the code block) to pause the code and then let it resume later at your choice? I could provide a few built-in methods to do this. That's actually a good idea, never thought of that use case. Let me know if it works for you, I'm super excited about it, because a lot of problems can now be solved in just a couple of beautiful lines. It's called Muffel and you can get it here: So if you want your player to be invincible for one second after getting hit, this is now valid code: invincible = true All the code you see in the video is actual Game Maker code that you literally write exactly that way. You can do stuff like "execute this block of code in x seconds" (delayed) or "every x seconds, execute this" (periodically). In combination with macros, I was able to basically create a new syntax for Game Maker :-D Since Game Maker 2.3, there are now actual functions similar to javascript and other languages. My brother is working on a game right now and I noticed that a lot of his problems are solved with alarm events, which makes his code hard to read and hard to maintain (you only have a limited number of alarms, you have to restart it to run it periodically etc.).
