In this video I take you on a journey through the eyes of the developer and the player. A passive understanding how to interact with a game is through the user interface (UI) or rather the graphical user interface (GUI). This interface allows the player to do predefined interactions to control aspects of the game and also gives the player feedback how the game works, like basic rules and an understanding how the core loop works. The GUI is not just for the player, it can be used also for control metrics/rules that are hidden for the player to control the flow of the game and to optimise it by the developer. These things may appear on the outside natural and understood passivly but are fundamental for a successful game to be done correctly.
I am not sure if I sufficiently explained this concept with the anecdote. So what I was refering to is that a child uses/learns from a haptical device like a screen to swipe/pinch/enlarge with their fingers to control content on the screen. And that small one from the story tried this by swiping on a glas tank for fish to enlarge the image, which to the child's suprise didn't work. All that is learned behavior but feels to us now natural (which it isn't).

![Wind effect fast my way vs shader [GameMaker Vfx]](https://i.ytimg.com/vi/dPymiS_KECM/mqdefault.jpg "Wind effect fast my way vs shader [GameMaker Vfx]
This video tutorial shows you how to achieve a simple wind effect which you see in a lot of 2D games with trees, bushes etc., basically foliage that is being moved to make the level pop more. Here I show you an easy out of the box way or the advanced shader way (based on Xors shader code).
The easy way is simply to have an asset player and apply the underwater effect on it. Then place all image you want to be be moved/animated through it there. Aaaaand that is it. The downside of this approach is that it can look a bot artifacty (if that is even a real word).
The default way is to have instances and use a shader for drawing. This approach looks cleaner, but you need to take into account that you have to assign each sprite its own texture page (so 4k texture page default size is no bueno). For more details how the whole code works visit Xors website and there you can find a sample project.

![Boost compile/test time [Game Maker | Basics]](https://i.ytimg.com/vi/deQKpHW-O5o/mqdefault.jpg "Boost compile/test time [Game Maker | Basics]
This basics video tutorial shows you how to use reduce testing/compiling time in GameMaker.
So this is the scenario, you write two lines of code and want to test your changes and hit F5. But this is not good because that takes more then one minute. How do we get this faster because waiting one minute or more each time for short testing isnt fun.
But lets start from the beginning, what is compiling and what has it to do with testing or even creating executables? To put it into laymends terms, compiling is the act of assembling or putting things together from different sources. That is what is happening when you press F5 and run your game in the virtual machine (VM) or the YoYo compiler (YYC). It stores all files in a temporal folder and create a useable/runnable version of your current project. So if you have tons of big images and high quality songs in your project you increase the compiling time by a lot.
To remedy this temporary:
- put no or dummy images/songs to reduce files size
- use compressed sound files (.ogg)
- use as little images in total which are not needed in early to mid stage production
- good hardware (cpu/ram + ssd) for loading fast in and out
In later to last stages of making your game you put in the art and music to not bloat/cripple up your testing/compiling capabilities. Having thousands of objects and scripts is not affecting the overall testing times (almost) at all.

![Update V2023.1 - No bling bling but 2 must have functions [GameMaker]](https://i.ytimg.com/vi/ePlAaqK8UFQ/mqdefault.jpg "Update V2023.1 - No bling bling but 2 must have functions [GameMaker]
The newest patch V2023.1 comes with some good quality updates. The highlight is the new move_and_collide function and audio_play_sound_ext. These two are worth the update by itself.
In a nut shell, move_and_collide is taking in vertical and horizontal movement inputs and checks if there is a collision, if yes you cannot go there. This is super easy to use for beginners and advanced users.
The audio_play_sound allows you to directly influence the sound file with a struct. It makes playing and controlling sound files more convenient. The other additions are that you can oscillate through a sound file with a sound effect (no idea what this is good for) and you can use sdf fonts, which smoothen pixelated fonts. This method is only of externally pulled fonts during runtime, so the use is limited. This feature will be in the future expanded to the internally stored fonts.
Sdfs are very powerful way to create light weight bitmap heat maps, which are use for fast light system or other means. Xor has a wonderful article for this:

Tldr:
- move_and_collide for easy collision setups
- customise sounds further

![Slime jumper [Game Maker Studio 2 | Enemy Ai]](https://i.ytimg.com/vi/eY4kcxdUH3s/mqdefault.jpg "Slime jumper [Game Maker Studio 2 | Enemy Ai]
This enemy ai video tutorial shows you how to make an enemy that that jumps randomly in GameMaker Studio. Typically those kinds of enemies are slimes for a reason.
The idea is quite simple. You need to the enemy that goes left and right like you maybe saw in my previews enemy ai videos. After that you setup a variable that runs down. Once that variable is 0 or smaller you reset the direction to an upwards angle plus set gravity to a value so that it pulls down the enemy. Now the enemy is jumping. To reset the jumping motion you have an additional collision in the step event that resets the jumping. Thats it!

This basics video tutorial shows you how to setup hexagon cells in GameMaker.
Hexagon cells are pretty popular in strategy games and can make each cell look fancy. Drawing/placing these cells can be challenging because their shape is not as straight forwards as rectangles. So what you need to understand here is that you have to place them correctly near to each other. Each horizontal line of cells is a sum of the cell width or the sum of a cell width plus half. The height is bit wonky also, since you cannot take the full height nor the half.
Tldr: It is complicated, not too much but a bit

![Bat Boy - Better then Shovel Knight? [Game Review]](https://i.ytimg.com/vi/fz1uDPOVQK0/mqdefault.jpg "Bat Boy - Better then Shovel Knight? [Game Review]
To be clear from the start, both Games are excellent (S-Tier). But only Shovel Knight has been a big success so far (deserved!). I think Bat Boys quality should put it into the line of best retro platformers on par with the inspiration. This review shows you what you can expect from the game in 2026 and what Bat Boy changes/adds to the mixture.
If you compare both games, they do have a lot of similarities, one is a goofy Knight with a shovel where as Bat Boy is trying to do that from the sports angle. The main difference is that Shovel Knight starts off strong but never evolves beyond that. Yes, Shovel Knight has spells to compensate for his short range but they are mostly used for combat. His mobility, doesnt change at all (beside one dash item). Boy Boy in contrast gets from each boss their signature ability which makes him at the end of the game a mobility power house. That gives the player a lot of ways to exploit the level design if they wish too. I am actually confused why nobody is talking about this game in high praises (maybe sports angle isnt doing so well as the joke knight angle). It does deserve it.
Tldr 9.5/10:
- Great graphics, charming animations, good music
- Tons of secrets, great level design
- Fair gameplay, no cheap deaths, Game feels like a breeze
- Abilities make the player a mobility power house
- Rewarding exploration
- 6 hours completion time (I want more!)

![Placing Towers on click [#3 Tower Defence in GameMaker ]](https://i.ytimg.com/vi/gL-ZSEaecXc/mqdefault.jpg "Placing Towers on click [#3 Tower Defence in GameMaker ]
This is the 3nd video in a short Tower Defence series made in GameMaker.
What is left now is to have a mechanism that allows us to place dynamically in the game houses on a grid. To snap to a grid we use the mouse x,y coordinates and substract the mudolo (rest values) from it. Then we assign a random sprite index to the instance and pass that information to on click created house also in. And last but not least we have two checks which if true disable placing a house at this part of the grid. First we check by a collision check if there is already a house being created on this spot/grid part and second a tile index check if on this mouse position a tile other then 0 was set (0 is default and not set). Thats it!
🚧 For the future: This series will have 3 videos where all the basics are setup and a 4th optional one where constructors are used as a solid spawning setup. The project can be downloaded and since it is ultra small, is free to use (graphics are free also, check out the notes)

This basics video tutorial shows you how homing can work in GameMaker Studio with 2 lines of code. There will be a follow up video on a homing rocket barrage like you see in games like Armored Core, but the cheap mans 2D version.
I got the inspiration from Ellaris who is a discord member, so thanks for the idea buddy! The 2 lines are very easy to do and work more or less but are a building block to advance this concept.
First we need to create the rocket and give it an inital speed, direction and angle to start of with and gradually change the flying direction.
So what are those 2 lines? Well, we add constantly in the step event of each rocket to it a value that gradually (delayed) turns towards its target position. For that we need the current direction of the rocket and the perfect direction from the rocket to the target (which we get by the rockets x,y and the targets x,y and get it by point direction). Then we get the resulting angle difference and use sign to clamp the result to 0,1,-1. That added to the current direction turns the rocket towards the the target, but we can use a fixed value to increase/decrease the turning around speed to our liking. Then we set the new direction to the image angle so that visuall it looks sound aswell. Thats it!
The code if found as usual in the comment section.
🚧 For the future: There will be follow up video that shows how to visually advance this core setup to an homing missile barrage
