Hyper-casual games are known for their simplicity, ease of play, and addictive gameplay loops. One such popular game is Stickman Hook, where a player controls a stickman that swings across obstacles and platforms using a hook. The goal is to reach the finish line by swinging, launching, and avoiding pitfalls. This game genre is not only fun but also relatively simple to create using a game engine like Unity.

In this guide, we’ll walk through the process of creating a hyper-casual Stickman Hook game using Unity, focusing on game mechanics, controls, physics, and how to build a satisfying user experience.

Key Features of a Hyper-Casual Game

Before diving into the technical details, it’s essential to understand what makes a hyper-casual game appealing:

1. Simple Mechanics: Easy to pick up and play without complex tutorials.
2. Short Game Sessions: Quick levels that can be completed in under a minute.
3. Minimalistic Design: Simple, clean visuals that don’t overwhelm the player.
4. Addictive Loop: A gameplay mechanic that’s satisfying and repeatable, encouraging replayability.

Now, let's move forward step by step in creating a basic Stickman Hook game in Unity.

Step 1: Setting up Unity Project

To get started, you’ll need to install Unity, the preferred platform for game development. Once Unity is installed, follow these steps to set up the project:

1. Create a New Project: Open Unity Hub, click on “New,” and choose the 2D template. Give your project a name like "StickmanHookGame."
2. Setup Scene: In Unity, a scene represents a level or a game state. You can start with a simple blank scene. Right-click in the Hierarchy panel and create a new empty GameObject, which will serve as the environment for your stickman character.

Step 2: Create the Stickman Character

For the Stickman Hook game, the main character is a stickman. You can either design a stickman using Unity's built-in sprites or create custom artwork using external tools like Adobe Illustrator or Photoshop. However, Unity’s 2D capabilities are perfect for this game.

1. Create the Stickman Sprite: For simplicity, you can use primitive shapes to design your stickman. A circle for the head and lines (rectangles) for the body and limbs. These can be created in Unity by adding 2D shapes and arranging them accordingly.

2. Rigging the Stickman: You don’t need to worry about complex skeletal animation. Instead, focus on movement using physics-based components. Add a Rigidbody2D component to the stickman, allowing it to interact with gravity and collisions.

3. Add Collider: Add CircleCollider2D for the head and BoxCollider2D for the body and limbs. This setup ensures that the stickman interacts with the environment correctly.

Step 3: Creating Hook Mechanism

The core mechanic of this game revolves around swinging from a hook, so let’s implement that:

1. Create Hook Points: These are points where the player can attach the stickman’s hook to swing across the level. You can create these points as empty GameObjects placed around the level.

2. Add Swinging Logic: In Unity, the swinging behavior can be achieved using hinge joints. When the stickman throws its hook, it attaches to a hook point and creates a swinging motion. Here’s how to implement it:

   • Add a LineRenderer to visualize the hook line.
   • Detect when the player taps or clicks the screen. On tap, calculate the distance to the nearest hook point.
   • If the hook point is within a certain range, attach a HingeJoint2D to the stickman, connecting it to the hook point. This will simulate the swinging motion.
   • When the player releases the tap, detach the stickman from the hook by removing the joint.

Step 4: Physics and Controls

In a hyper-casual game, the controls need to feel intuitive and responsive, as they play a crucial role in maintaining the addictive nature of the game.

1. Player Movement: Since the hook mechanics are based on physics, the player movement will naturally be influenced by Unity’s 2D physics engine. You can fine-tune the parameters of the Rigidbody2D component, such as gravity scale and drag, to get the desired effect.

2. Player Input: In a hyper-casual game like Stickman Hook, the input system is usually very simple:

   • On touch or click, shoot the hook towards the nearest hook point.
   • On release, detach the hook, allowing the stickman to fly forward based on momentum. Unity’s Input system can handle these controls easily with functions like Input.GetMouseButtonDown(0) for detecting taps and Input.GetMouseButtonUp(0) for releases.

3. Momentum and Swinging: Adjust the physics properties like angular drag, mass, and gravity to ensure smooth swinging. Test different settings to make the swinging feel natural yet engaging.

Step 5: Designing Levels

Level design is a key aspect of the Stickman Hook game. You want to keep the levels simple yet challenging enough to keep players engaged. Each level should feel unique, even if the core mechanics remain the same.

1. Platform Placement: Platforms should be spaced out to encourage swinging. Some should require longer swings, while others should be placed closer to test the player’s reaction time.

2. Obstacle Design: Adding obstacles like spikes, moving platforms, or deadly traps can increase difficulty and make the gameplay more dynamic. These obstacles should be placed in ways that make the player consider when to swing or detach from the hook.

3. Progression: Start with easy levels where the player can easily reach the finish line. Gradually increase difficulty by adding more complex hook points and obstacles.

Step 6: Visuals and UI

Hyper-casual games thrive on clean, simple aesthetics, so it’s important to create a minimalistic design that still feels polished.

1. Background: Use solid colors or gradient backgrounds to keep the focus on the stickman and the platforms.

2. UI Elements: Add basic UI elements like score, level progress, and restart buttons. The UI should be non-intrusive and easy to navigate.

3. Animations: Even though the game is simple, adding small animations like a bounce effect when the stickman lands on a platform or a quick swing animation can make the game feel more lively.

Step 7: Audio and Feedback

Audio plays an essential role in the player’s engagement with the game. Add simple sound effects for actions like swinging, hitting a platform, or completing a level. Additionally, include some background music that fits the light-hearted and fast-paced nature of the game.

• Sound Effects: Use different sound effects for successful swings, impacts, and falls. It enhances the player’s sense of achievement.

• Haptic Feedback: If you are building for mobile, consider using haptic feedback for key moments like hook attachment or level completion. This provides another layer of satisfaction for the player.

Step 8: Testing and Optimization

Once your game is fully functional, it’s crucial to test it extensively. Playtest the game on different mobile devices to ensure smooth performance. Optimize the game by reducing unnecessary physics calculations or lowering the number of assets loaded at once.

1. Performance Testing: Make sure the game runs smoothly, even on older devices. Stick to a frame rate of at least 60 FPS for fluid gameplay.

2. Bug Fixing: Test edge cases, like what happens if the player taps repeatedly or detaches the hook mid-swing. Iron out bugs to ensure a polished experience.

Conclusion

Creating a hyper-casual game like Stickman Hook in Unity is a rewarding process. By focusing on simple, yet engaging gameplay mechanics, you can build a game that’s both fun and addictive. The key lies in balancing the physics, controls, and level design while maintaining the minimalist aesthetic typical of hyper-casual games. With proper testing and optimization, you’ll have a polished game ready for the app stores.
