Airport Explorer

The cabin is a small indoor space, just like a real-world cabin. So I made the player's collider thinner to make it easier for them to move around while doing tasks.

At the entrance, I set up two computers, two buttons and a score display screen. Players will face this table right from the start.

These two computers each have their own job. The left one controls level starts, keeps track of objectives, and decides whether to go to the next level or end the game. The right one is for watching tutorial videos.

There are two buttons on the front. The left one restarts the game, and the right one exits it.

There are timer displays all around showing the game's remaining time, so players can check the time easily anytime.

This level's map is huge. The player mainly moves around a warehouse and an airplane, and there are vehicles there.

I put invisible walls around the planes and warehouses to stop players from going too far. If you look closely at the picture, you can see blue lines around the airport—those are the invisible walls.

This is the warehouse. It's a small part of the map but bigger than the others. Players start at the truck location, on the right side of the top-down view.

Viewing the warehouse from different angles.

This is the menu design. It looks like a console and works just like the old desktop menu—you can start or exit the game, and check out introductions and tutorial videos.

There’s only one menu, but actually two console models. The scene is too big, so there are two tasks, each with a fixed spot. The first is moving luggage to the vehicle, and the second is moving it to the conveyor belt.

I put console models at both fixed spots, and the 2D UI can switch between the two sides. When the player gets close to one console, the UI menu is basically independent. Since this menu needs scoring and timing functions, I did it this way because I was a bit lazy. I didn’t have to change the scripts, and it also helps with optimization.

I added lots of useful info displays to the tractor. The black screen shows how much luggage is on board. The white screen is a location indicator with text direction reminders. And the red part of the compass below always points to the destination.

The warehouse map looks huge, but players can only move around a quarter of it. I put invisible walls to stop them from wandering. When a player gets close, the wall turns red gradually, and only NPC carrying goods can go through.

This is the menu, the same one for loading operation levels.

By the scanner on the table, besides the buttons needed for the task, there are how-to videos and paper instructions.

The video didn't show the tutorial levels, so let me explain them here.

I've put all the levels into one scene called the tutorial. It helps players start the game quickly—they can learn to play all or some levels before the official start. The trial is optional, and this scene also lets you pick and enter the actual game levels.

I put all the game content mechanics into a big building to make an indoor effect, like an indoor amusement park feel.

I put the main menu at the start of the map, so players see it right away.

The first page shows how to control the game, the second introduces the game content, and the third is the tutorial map. The fourth page has settings—you can switch languages between Chinese and English, restart, or exit. The fifth page is the credits.

To let players move faster, I added two conveyor belts that go back and forth. Players can move automatically just by standing on them.

I made a special room for picking levels. There's a menu here where you can choose all the game levels.

Outdoor areas have themed titles and tutorial videos to let players preview the game.

There are also instructional videos, gameplay introductions and game objective statistics(scores) inside.

Take the tractor experience as an example. It's an indoor info board showing title, intro, video and objectives.
