Uploaded June 2025 | Updated September 2026, 5 hours ago
This video tutorial shows you how to setup the first part of an inventory system that is modular and later on it will be advanced to suit more then basic needs.
Here we will make a system for a fixed inventory where all items are unique, their position is unique and if tey are collected or not and. That means all items are preset in advance and the player "only unlocks" them.

This is the 6th 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.
🚧 For the future: This series is under construction and since views have been super low, I have to cancel it. It seems the interest and my method didnt bind enough people to actually watch it.

![How did the Heartbound developer go viral [Marketing for Indie developers]](https://i.ytimg.com/vi/qPE8KWHQVX8/mqdefault.jpg "How did the Heartbound developer go viral [Marketing for Indie developers]
This video shows you a theory how the Heartbound developer Piratesoftware went viral and what you as an indie developer can learn from it. Congrats to Piratesoftware having achieved what only a tiny handful of people can achieve. 1 million subs on Youtube.
This theory was made in a quick and dirty research from my side (glorious 15 minutes). But still it may be valuable for indie developers that want to emulate his success or copy something from him because his numbers are pretty good (social media, sales of Heartbound).
So from what I could gather on the internet, following things went pretty well for Priatesoftware.
1. His game was covered 6 years ago by a really big streamer/influencer (March 2024, 30mio subs) and the audience plus the streamer did give positive feedback towards the demo of his game Heartbound. I played it myself and can say it is well crafted. That is a really good start.
2. He got promoted 3-4 months ago by another big time influencer where his numbers shot up again with strong keywords. Between those his YouTube channel/twich dev stream was earing steadily subs (and views) but not as exponentially as with his 2nd flappy bird moment (the one you see right now). The conclusion is here that the grind (make your game, create marketing videos/streams/blog posts, important also) is being dwarfed by getting viral and surfing on the wave.
But hey, maybe I am missing something. Not all makes sense. Let me know.

![Persistance or carry over values [Game Maker | Most know Basics]](https://i.ytimg.com/vi/qxTga9kBpKQ/mqdefault.jpg "Persistance or carry over values [Game Maker | Most know Basics]
This basics video tutorial shows you what persistence, aka carry over values/instances, mean in GameMaker.
These concept is pretty simple, you want to carry over values like health ammo etc. during runtime into other levels/rooms. Since GameMaker and other engines front load things, once you jump/change the room all the old values/assets are being deleted and the new rooms things are being loaded in. So how can you carry over values? You flag one or more instances as persistence, and they are not being deleted by the room jump. Thats it!
Tldr:
flag instances as persistence to no get delete by room jump

![Draw outlined text - the easy way [Game Maker | Basics]](https://i.ytimg.com/vi/qzROcUYf3G4/mqdefault.jpg "Draw outlined text - the easy way [Game Maker | Basics]
This basics video tutorial shows you how to draw your text with an outline the easy quick and dirty way in GameMaker.
The idea is quite simple. You use the fx outline and assign it to an instance layer with the inspector. Then you place an instance on that layer that does a regular draw text command. All drawn texts have on this layer the same outline attached. Thats it!
Note that this method has a limitation because you can only have one size of the outline set to it. And if you use the outline make sure to have no interpolation/antialiasing on the font (see the result in the video) which then wraps the outline around totally transparent spots which does look very ugly the bigger the font is. The fx layer affects all draw evens, texts included (fonts are being saved in the texture page, so they are images also).
Tldr:
assign one instance layer with the outline fx (via inspector)
place the instance on this layer + draw some text in it

So you could see this as a extra kickstarter in your career plus get some goodies on the way.
What they want you to submit is a document which entails your ideas of a game you would like to produce with some rules attached to it. You are here basically the game designer (in a limited form) and try to pitch your idea (a game design document in an early conceptual stage).

![Last position bomber/laser [Game Maker | Enemy Ai]](https://i.ytimg.com/vi/rHTaVOErKmw/mqdefault.jpg "Last position bomber/laser [Game Maker | Enemy Ai]
This basics video tutorial shows you how to make a last position enemy tracker which shoots down a laser. You see this being done via a big laser or mine or explosion on the last postion in boss fights or regular enemies to keep the player moving and to zone the player.
The idea is simple. We need an enemy that runs down a timer( here an alarm) and once the alarm event is triggered we spawn in on the last position recorded of the players x, we create an effect instance that marks a position. We run down a timer in this effect/marker instance and destroy it after 2 seconds. in the destroy alarm even we create a 3rd instance, which is the laser. This one also has an alarm which destroy it after 2seconds also.
Thats it!

![Spawns + Redirect [#1 Tower Defence in GameMaker ]](https://i.ytimg.com/vi/s-RYjDMlKDA/mqdefault.jpg "Spawns + Redirect [#1 Tower Defence in GameMaker ]
This is the 1st video in a short Tower Defence series in GameMaker.
The idea is to make a super simple system that allows thousands of spawns to run in a conga line without much customization or using any path or complicated system. In this video we create a spawner that creates in its looping alarm event a spawn. There you only give the spawn a speed value and direction where to go to. The second part if where we setup a redirection system that redirects the spawns up, down, left or right. So here we simply create a collision event in those redirection instances and change the spawn direction (and xscale) when these bump into each other. 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 vfx particle video tutorial shows you how to create debris/rubble for explosions, impacts, hits etc. in GameMaker with just a few mouse clicks.
The idea is quite easy. You need to create a new Particle System asset and customize it so that you have a burst of particles in a parabollic movement. To do that you need to set the direction of the burst in an upwards arch (here between 20 to 160), give it a random size, add some gravity, apply a sprite of choise or use the pixel/disk shape and give it variable speed values to look organic. This video shows you additionally a dummy emitter as a reference, so you can get a feeling how the particle should like in comparison. Not necessary but a neat trick for fine tuning. Optionally you can increment the orientation, so that you have a spin in it. Thats it
Tldr: - vfx for the win
Note: This only works with the latest update 2023.2 (dropped yesterday) and upwards!
