Uploaded December 2023 | Updated September 2026, 26 minutes ago
This basics video tutorial shows you what scope and encapsulation mean in GameMaker.
These to interlocking concepts are a must know in GameMaker and generally in programming because all programming languages have them in one way or another. In GameMaker scope is being refered to what instances (and their scripts/functions) can read and override from each other.
The first scope is the default one that all instances have access to each other (instance variables colored in blue or green). These self created variables or pre-set variables shipped with the instance can be accessed and rewritten. The second scope is for local variables (localvariables colored in yellow) that have a limited life time (event, script, function) and are bound to the instance calling it. The third scope is global (global variables colored in purple). These variables are once set static ones and saved in memory, so they don't rely on the instance existence to be access and changed. A sub category of global variables is enums or macro which are one time set and then locked. So you can access them but never change their values.
Tldr:
scope - accessabilty of code/things, which can be normal, local and global
encapsulation - bundling things into a unit, java classes for even hiding /Gamemaker objects, functions
idea is to bundle, hide, seperate interal and external code

This basics video tutorial shows you how to setup make a radial orbiting instance around a target in GameMaker Studio like you see in Megmana games
The idea is quite simple. You need an anchorpoint from where to simulate a radial movement around it. Next you define a radius that is being increased all the time and a distance from that anchor point. That is pretty much it.
I wasnt sure how to call this, so this could be the same: circular movement, circular movement around given point, object orbit, radial movement. All mean the same thing, you have one fixed point to rotate/orbit around.

This visual effects video tutorial shows you how to create a vignette in GameMaker with a few mouse clicks.
The idea is quite easy. You want to enhance your game by darkening out the edges of your screen. For that you can use the inbuild vfx layer vignette and all you need to do is to play around the edges and sharpness value to get the outcome you are looking. If you have a camera setup, the vignette will be stretching over the cameras view values to fit and look good. Thats it!
Trivia: Vignettes are being used in video games for:
- scopes (hard vignette)
- start screens, cut scenes or overall atmosphere
- to indicate critical health/distress/horror
My old video on vignettes where I show you how create an image of an vignette and draw that on the screen:

// content of this video:
In this video I take you on a journey of a game developer where it is crucial to have an impact on the player the moment the game is starting. The first titel screen gives passive informations of what to expect from a game. It sets expectations, what is the content of the game, what kind of game is the player going to play. Does the graphical presentation entice or repell the player from further playing. All these and other thoughs are part of fine tuning a (hopefully) successful game.

This basics video tutorial shows you how to make a overworld map with a pointer jumping to an level slot the easy way in GameMaker Studio.
The idea is quite simple. You want have 2 types of objects, one which is the pointer and one that is a ui element indicating possible location (buttons) to enter on the map. For that you simply drag your map sprite/image on the asset layer (not recommended but it does work) and place the pointer and the locations on the screen. Then you simply have a mouse click event in the location on which the point is being repositioned on their spot. Thats it!
The optional part is using the animation curves to hover the pointer and animate the location buttons to make the whole thing look neater. Not necessary but why not.
If you are unsure about animation curvers, I got you covered:

This is the 2nd video in a series on remaking Vampire Survivors in GameMaker.
The video tutorial shows you how to create in a very simple way to create a randomly generated ground. The idea is quite simple. You have a sprite stripe (or a big tileset sprite sheet) and you loop through all possible tile positions of the room with a double loop to set a random tile from this tileset. Image it like this, you let GameMaker pick one of those brushes/tiles and set to each possible postion a random one. Thats it.
You can find the whole code in the comment section.

I though I can give you a quick and dirty guide through all essentials that this text render has to offer.
What can this tool do? You can chain on any positon of the text multiple commands that do cool effects like wobble, wave or standard operations to increase the text size or color a word. There is even a typewriter function included which is a god send to an easy to use system for dialogs ingame.

This is the 4th in a short series of remaking the battle system which you see in Undertale in GameMaker.
What is Undertale?
Undertale is a video game made also in GameMaker by Toby Fox where
you play as a child that is being trapped in an unknown world and your job in this linear story is to progress. The difference is that you can genocide monsters, be neutral or even befriend them. This throws the concept of enemies being simply neutral farm on its head.
// Part 4
This time we need indicate to the player that if the heart clips/collides with any obsticle/bullet we need to put the state into a hit state that blinks the heart. For that we have to have a timer running down and once that timer is below 0 we set the alpha to 0.4 or 1 depending what it currently is. That is it!
🚧 For the future: This series is under construction. There will is a free downloadable project file for everybody, so you can grab and do whatever you like to do with it (you can credit me, but not necessary). Also, this video series will be handled like my Hotline Miami series. If the views drop off a cliff (that I do see happening) it will be then discontinued.

This basics video tutorial shows you how to conver automatically from one type of programming language into another in GameMaker.
To clarify, GameMaker has two types of programming languages, one called gml, which stands for GameMaker language which is a script programming language. The other ones is a icon heavy way to make games which is called gml visual formerly known as DnD.
To fast forward, yes you can convert from gml visual (dnd) to gml with ease, just hit right mouse button and convet the specific event/script. But can you do the same the other way around? Well, technically you can but not how you would expect it. The conversion is then running hybrid with the gml part as an addon and the rest with gml visual. This is a bit of a let down because for beginners who prefer the visual programming style with gml visual and want to convert gml projects, well they are pretty much out of luck. There is currently no way for a clean conversion where you can flip flip between those two styles on the fly.
Disclaimer: I have never had that issue nor need and never encountered any gml visual (DnD) projects from ar site, tutorial or video etc. .

We had in the last years not so many tutorials on making inventory systems. So this it a guide how to get one running. In this part we only create in the constructor a new entry and store in that the sprite_index, so basically how the thing we collect/add to the inventory looks like.
From that I will deviate first to a fixed inventory (route B) and then to a Nioh style inventory where you can scroll, add unlimited entries and split into categories (weapon, armor etc. )
