Uploaded May 2022 | Updated September 2026, 11 hours ago
This is the 7th video in a series on remaking Vampire Survivors in GameMaker.
The video tutorial shows you how to use the weapons created to damage the enemies and if their hp pool is zero to destroy them. For that we first assign a damage value to the weapon parent and assign a hp variable in the enemy parent which is getting substracted later on. So we need to create a collision rectangle list (or any other collision you prefer) to get the id of the enemy being hit/collided with and there we substract from each enemy hit the hp the damage value. If the hp is zero or below we remove the enemy instance from the game. That's it!
To refine this system, we organize the damage values of each weapon in the player and each time we spawn a weapon we grab the current value, which will increase/change during gameplay. Normally you would do that in an outside controller object, but this simplified version does the trick also. Also note that we use a collision [rectangle] list because this is making sure we get each step all the instances getting hit by the weapon. The regular collisions only collide with one instance each step which would result in instance visibly hit not getting any kind of damage or hp reduction.
🚧 For the future: This series will will build expanded the further we go into the series.

![Structs - light objects [Game Maker | Basics]](https://i.ytimg.com/vi/k874pndLJEs/mqdefault.jpg "Structs - light objects [Game Maker | Basics]
This basics video tutorial crash course shows you what structs are in GameMaker. An advanced video will go into constructors and more functions.
Structs are in principle ligh object or simply data containers. These data containers have a specific syntax which is very similar to the JSON standard (OOP: object oriented programming). Jason stands for Java script object notation and is an universal file format for human reading. The idea is that you have keys (the name of a variable) and values (the actualy value assigned to the variable) inside a struct. That can be used to created topdown hierarchies (nesting, a struct in a struct etc.) that can be chained (with the dot operator) together .
In short: Structs are light weight object with key values data inside them. Thats it.

![External Hit Animation - Juice up any game [GAME DESIGN CODE]](https://i.ytimg.com/vi/kalIpZffZ3o/mqdefault.jpg "External Hit Animation - Juice up any game [GAME DESIGN CODE]
This video shows you how to juice up any video game with good Game Design. External Hit animations are the backbone of any video game and indicate to the player with an animation that something is happening to the player/npc instance. Note that external hit animations are coming from the outside and can be considered as an additional animation being drawn on top of the instance being hit and can be one or multiple animations being created.
There are two most common ways how to do this. A visual and easier way is to simply have an hit animation image that is running down its animation and once it is finished you then remove it. That can be used as a default hit animation for all cases or as specific type of hit animation (elemental, weapon hit or internal bleed/oil/rubble) or both.
The most common way in video games is to use particles that are being spawned in a particular way. This approach is more complicated and needs fine tuning becaues these animations are a composite of different particles. A vanilla hit effect for example has a fast moving ring that goes from the center and exands plus small lines that rapidly move out of the center in an circular fashion.
Tldr:
- sprite/image or particles or both to create hit effects
- can be default, specific internal/external effects
🚧 For the future: There will be follow up video that shows these hit animations with code and a visual

![Metroidvania Map the easy way - Concept [GameMaker]](https://i.ytimg.com/vi/kgZjhEuhgNc/mqdefault.jpg "Metroidvania Map the easy way - Concept [GameMaker]
This video tutorial covers the concept of how to create a metroidvana map in GameMaker. Every good sidescroller/metroidvania has it and now I can offer a simple, scaleable and performative version to you without tanking your performance.
The idea is quite simple, you define how many columns and rows you want to have, draw on each cell one empty image/sprite and draw one active cells recolored rectangle and their walls (connector walls optional). Or do create for each cell one specific sprite (delux version) where you have less repeated cells to work with but map clarity is much improved.
The following parts will be coding and add, start location, visited/not explored cells aswell as map movement and zooming.

This enemy ai video tutorial shows you how to make a contra style turret that rotates slowly towards the player in GameMaker Studio.
The idea is quite simple. You first define a distance towards the player on when entered the turret starts to rotate toward him. Because we dont want an instant rotation we delay the rotation. Then when we are in a good enough angle towards the player we can start shooting. Thats it!

This visual effects video tutorial shows you how to almost create a cool looking loot visual effect like you see in Nioh, the souls series or other games but this time for in a 2D engine.
The idea is to create a cone texture and use that as a particle to be spawned and moved slightly upwards. This method works in any engine and is not exclusive to GameMaker. If you use Unreal/Unity/Godot you got 3D particles and well, they are superior in looks. In GameMaker we use the inbuild particle System to create the 2D particles and optional other effect to round it off. Thats it!
// to create and spawn the visual effect use this code in GameMaker:
var partSys = part_system_create_layer( Instances, 0, ParticleSystem1 );
part_system_position( partSys, x, y );

This vfx video tutorial shows you how to visually upgrade your splash screen/backgrounds in GameMaker with a parallax plus some neat and cheap light effects.
The idea is quite simple: You need to have seperated images to create a pseudo 3D effect by enlarging and making them smaller in a rythmic slow time frame. For that you simply need to use the GameMakers animation curves to tween in a loop. You also use the animation curves for the flashing lightning effect aswell as for some fake blinking lights on important spots. If your images are angled not like in the video straight forward (for example to the right like in Fury Unleashed) you also can use the animation curves to move (change the x,y position of the layers) where want to move. Thats it!

![Hit Animation - Juice up any game [GAME DESIGN]](https://i.ytimg.com/vi/oB5Y90vniCo/mqdefault.jpg "Hit Animation - Juice up any game [GAME DESIGN]
This video shows you how to juice up any video game with good Game Design. Hit animations are the backbone of any video game and indicate to the player with an animation that something is happening to the player/npc instance. This state is a short lived one and normall between a quarter of a second or even shorter. The same method can also be used for buttons or any other gui elements.
Here we will go over the internal hit animation follow by other videos to external animations/effects on top.
To understand all this we need to seperate the internal hit animation into its parts. The first part is the most common practise where the player/npc instance is being recolored/blended or shown with a low opacity (or even 0). This is being seen as a flashing or blinking to the player. The second part is to have a fully animated hit image to be swapped or just another sprite that resembles a hit. The third one is a squashing animation done mostly in code where the image scaling is being distorted and lerped into its original scaling. Most games do use all 3 methods as a combination.
Tldr:
- recolor/low
- swap images
- squish and resize
🚧 For the future: There will be follow up video that shows these hit animations with code and a visual too how to do those in GameMaker and JuiceFx.

![Move_and_Collide - Hyper speedo, in detail [Game Maker | Basics]](https://i.ytimg.com/vi/oHgGEZ5Kt2U/mqdefault.jpg "Move_and_Collide - Hyper speedo, in detail [Game Maker | Basics]
This basics video tutorial shows you how to setup with the new move_and_collide function a platformer with slopes in GameMaker.
To be very frank this is a first shot of making a platformer easyier to build with the new move_and_collide function from the recent 2023.1 update.
The idea behind move_and_collide is very simple. You put in a dx, dy value which are prediction points where to move to (speed values or fix points or simply a number). It goes as followes, the first input value (dx) is taking the current bounding box of the instance (player, etc.) and adds to that the dx value and checks if there is an collision, if not the player will be moved there. This process is being splitted up into an internal iteration of pieces sliced up of the total input value dx (partly move, check collision, if not move partly, check for collision and so on). Same goes for the dy value also but this time vertically. There are other input values like xoff/yoff and these just are an anstruction (push upwards/sideways) what to do if we are colliding/clipping. The last input values are max_x_move/max_y_move and are basically maximum speed values and prevent hyper speedo shown in the video.
Note: This is an first attempt to unify the system into a platformer setup but as it seem, this is okay but not perfect for all situations. So if you got a better fix or a good idea how to make the whole thing universally useable, I would love to hear and share it with the community.

Besides that you get overal some minor quality updates for more supported languages, a fix for steamworks, fine tuning on texture pages and redefining gml/dnd or a long list of bugfixes.
A change is that your project made in 2022.2 and now 2002.3 is not compatible with older projects of GameMaker Studio. Please take this factors into consideration when you are about to update your ide.
Note: I personally had and have some issues with the newer versions of GameMaker Studio which broke a project I am working on, so I am for now stuck on V2022.1. But please note that for most people this wont be an issue.
