Welcome to Dev-initely Mario!

This channel is all about game development, Unreal Engine, Blueprints, and building real gameplay systems step by step.

Here you will find practical tutorials about player controllers, interaction systems, inventory, UI, level design, horror mechanics, ghost AI, Behavior Trees, Blackboards, AI senses, event systems, evidence logic, journals, mission results, and complete gameplay loops.

๐Ÿ“ข Short Channel Update

Unfortunately, weโ€™ll be offline until at least Wednesday.

Our current hardware has finally given up, so right now Iโ€™m unable to properly record, edit, or continue working on the videos.

The good news: new hardware has already been ordered and is on the way. As soon as everything arrives and is set up, weโ€™ll continue with the card game series and the other planned content.

Iโ€™m sorry for the short break, especially because we had just started working through your feedback and the next improvements.

Thank you for your patience and for sticking with me. โค๏ธ
Hopefully weโ€™ll be back up and running very soon!

See you again from Wednesday at the earliest! ๐Ÿ› ๏ธ๐ŸŽฎ

It has already been an amazing journey:

๐Ÿ‘ป We started with the Ghost Hunting Horror Game
๐Ÿƒ Then we built our Card Game
๐Ÿš And now we are working on the new Road Trip Game

Seeing the channel grow while we build all these Unreal Engine projects together means a lot to me.

๐Ÿ† The Community Has Decided โ€“ We Have a Winner! ๐ŸŽฎ

The poll for our next Unreal Engine project after the Horror Game is finished, and we have a clear winner!

๐Ÿฅ‡ 1st Place โ€“ Co-op Road Trip Game ๐Ÿš
Inspired by RV There Yet? โ€” 59% of the votes!

And weโ€™re not wasting any time: the very first video for this new project is coming TODAY! ๐Ÿ”ฅ

Weโ€™ll start building the game step by step, including co-op gameplay, physics, vehicle mechanics, exploration, interactions and all the chaos that comes with a road trip game. ๐Ÿ˜„

๐Ÿฅˆ 2nd Place โ€“ Trading Card Game ๐Ÿƒ
Inspired by games like Magic: The Gathering and Yu-Gi-Oh!

The Trading Card Game will become our next project after the Road Trip Game.

But you wonโ€™t have to wait until the entire first project is finished! Whenever we reach a point in the Road Trip project where we need to wait for the results of a community poll or another decision, weโ€™ll use that time to release videos for the Trading Card Game instead.

So in practice, weโ€™ll have one main project while slowly building up our second project alongside it. ๐ŸŽฎ๐Ÿƒ

Thank you to everyone who voted! โค๏ธ

Iโ€™m really excited to start this new chapter with you โ€” and the first Road Trip Game video arrives today! ๐Ÿš๐Ÿ”ฅ

Which type of game would you most like to see us build together from scratch?

The winning option will become the next major Unreal Engine tutorial series after the Horror Game. ๐Ÿ‘ปโžก๏ธ๐ŸŽฎ

๐Ÿ  The Poll Is Over โ€” We Have a Winner!

The community has decided: with 67% of the votes, our first map will be:

Single Floor โ€“ 3 Rooms + Basement

Thank you to everyone who voted! On Thursday, July 28, the Ghost Hunting Game in Unreal Engine 5 series continues, and we will begin working on the layout and blockout of our first Level.

The basement should give us plenty of opportunities for dark rooms, narrow paths and some terrifying ghost encounters. ๐Ÿ‘ป

See you on Monday!

What Kind of House Should We Build for our first Map?

We currently planning the first level, and I'd love to hear which house layout you'd like to see us build.

๐Ÿ—ณ๏ธ The poll will stay open until Friday 24.07.2026.
Until then, the main series will be paused while I wait for the results.

Don't worryโ€”there will still be new videos! During the break, I'll upload tutorials covering interesting standalone topics, systems, and features for Unreal Engine 5.

Thank you for voting and supporting the series! ๐Ÿ‘ป

๐Ÿ‘ป Upcoming Unreal Engine AI Tutorials
Starting tomorrow, Friday, July 17, we will continue the AI section of our paranormal horror game.

The remaining systems are too important to squeeze into only two videos, so I will divide them into three focused tutorials, with our regular Cleanup Day on Sunday.

Friday, July 17 โ€“ Ghost Interaction System

The ghost will learn how to interact with the environment.

We will add:

Throwable-object interactions
Door interactions
Light-switch interactions
Support for other usable objects
Checks that determine whether an interaction can currently be executed
Reusable interaction logic
Testing with multiple objects in the level

At the end of the video, the ghost will no longer be limited to movement. It will be able to influence the environment around the player.

Saturday, July 18 โ€“ Random Ghost Event System

We will then create the system responsible for selecting and executing ghost events.

The video will include:

An array containing available events
Random event selection
Execution-condition checks
Choosing another event when the selected one cannot run
Executing valid events
Protection against failed or blocked tasks
A four-second delay after every three completed AI tasks
Debugging the selected event and execution result

This will make the ghost more dynamic and prevent it from repeatedly attempting events that are currently impossible.

Sunday, July 19 โ€“ Cleanup Day

Sunday will be dedicated to cleaning up and improving the project.

We will review the systems from the week, organize Blueprint graphs, rename unclear elements, remove unnecessary debug logic, fix smaller issues, and prepare everything for the Hunt system.

Cleanup Day helps us keep the project understandable as the AI becomes more complex.

Monday, July 20 โ€“ Hunt Timer and Crucifix System

The final video in this group will complete the Hunt flow.

We will work on:

Instantly starting a Hunt
Switching the ghost into its Hunt state
Starting and managing the Hunt timer
Automatically ending the Hunt
Resetting the AI afterward
Checking for Hunt-blocking items
Preventing or interrupting a Hunt with a crucifix
Tracking crucifix uses
Adding a cooldown before another Hunt can begin
Testing the complete Hunt lifecycle

Once these videos are finished, the ghost will be able to interact with the environment, execute random valid events, pause between groups of tasks, run timed Hunts, and react to a crucifix.

Which of these systems are you most excited to see? ๐Ÿ‘ป
