This enemy ai tutorial shows you how to make an enemy that bounces off walls (ricochet) with only 3 lines of code in GameMaker Studio.
The idea is quite simple. You give you enemy a start speed plus a direction where to go to. Movement is now setup, the automatic bouncing work when you have a collision with an instance wall which needs to be flagged as solid. To automatically change the enemy's direction just input move_bounce_solid and viola, it does now bounce off walls
This system can be used for bullets that reflect, bounce of walls also.

![Steam capsule art, what is there to know? [Marketing for Indie developers]](https://i.ytimg.com/vi/hfZHMi1JFNY/mqdefault.jpg "Steam capsule art, what is there to know? [Marketing for Indie developers]
This video shows you the basic theory behind making a Steam capsule art image and what kind of trends are visible so that you can use these informations on your own games capsule art.
If you have been wondering what you can do to get more attention towards you game with your capsule art or why should be actually in there and as well as you are curious what kind of trends of the topseller are being set as standards, well then this video is for you. The second part (learn from the top seller what works and see trends) is a follow up video because it was too long and rambly.
If you just want the quick and dirty tldr info, here it is:
1. First establish some basic rules to follow:
- few elements, less is more
- focus points/high lighted things/visual hooks (via color/art)
- hierachy of elements (top left to right)
- style/color consistency
- balance/symmetry
3. Trends
- no pixel art
- dark themes, dark colors, male audience focus
- emphasis on a head/action/prop
- household names can get away with all
- text is mostly white/golden/orange/brown black
- no idea on your own capsule? Open skys and fog and text
- no gore/no sexual stuff

This basics video tutorial shows you how to access data from structures like ds_list, ds_grid, ds_map or arrays in GameMaker.
The idea is quite simple. You create your own data like a ds list or an array and want to access/read out the value stored in there. Accessors are a shorter way to do that with a specific letter for each data structure. So if you want to access a specifc index of an array you can use the @ letter or for example for the ds_list the | letter. Thats it!

This vfx tutorial shows you how to make the fog effect like in Dead Cells with a few mouse clicks in GameMaker.
Before the newest patch 2022.8 you could also create this effect with particles which is a bit more difficult and resource intensive then now. We now can use the newest visual effect: Fractual noise, which overlays the area/screen with a fog like texture to enhances the graphics of you game. You simply create a black colored sprite, give it a transparent opacity and place it on an asset layer. Then you assign this asset layer the fractual noise effect. Play around with the opacity and the values in the inspector until you get the result desired. Thats it!

This basics video tutorial shows you how to depth sort (depth system) in GameMaker.
Things feel natural if they are being draw correctly. Image a stack of cards and it is obvious that the top card would be visible to you. So what we do is to check where the instances are and sort them to their own depth (or their own layer so to say) according to their y position in the room. We cluster all the instances into a parent object and swap their current depth to their -y value. We do that with the with statement that allows use to go through all the instances and swap their own depth. Thats it!

![Weapon damage [#7 Vampire Survivors Remake in GameMaker ]](https://i.ytimg.com/vi/k3evjBNv0Cg/mqdefault.jpg "Weapon damage [#7 Vampire Survivors Remake in GameMaker ]
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. Thats 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.

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
