How to Make Your Unity Player Move with a Moving Platform

In game development, one common challenge is ensuring that game objects behave as intended while interacting with dynamic environments. For instance, when you have a player on a moving platform, they must move in harmony with that platform. Failing to achieve this can lead to frustrating gameplay experiences, as players may end up feeling detached from the environment.

In this guide, we'll address a particular issue faced in Unity game development: how to make a player character stick to a horizontally moving platform. Let's dive into a straightforward solution that can enhance your game mechanics.

The Problem: Detached Player Movement

When you have a player character on a platform that moves horizontally, the expectation is that the player should also move with the platform. However, developers often encounter the problem where the player's position remains stationary, leading to an awkward gameplay experience.

Scenario: A fast-moving platform causes the player to appear as if they are standing still or floating in mid-air.

Impact: This issue can break immersion and lead to gameplay frustration, making it essential to resolve.

The Solution: Making the Player a Child of the Platform

The Simplest Solution

The easiest and most effective way to have the player move with the platform is to simply make the player a child object of the platform they are standing on. This strategy allows the player’s position to update alongside the platform's movement. Here’s a step-by-step guide to implement this solution:

Identify the Platform: First, ensure that your moving platform is correctly set up in your Unity scene.

Parent/Child Relationship: Modify the hierarchy such that the player becomes a child of the platform:

In the Unity hierarchy, drag the player object onto the platform object. This sets the player object as a child of the platform.

Adjust Rigidbody2D Settings: Ensure that the player’s Rigidbody2D component is set to prevent physics from interfering with the new hierarchy (e.g., turn off gravity if necessary).

Collisions Management: Make sure you have the appropriate collision detection layers set up so that your player can still interact with the platform without issues.

Before setting the parent:

Player (Rigidbody2D)

Platform (Moving Object)

After setting the parent:

Platform (Moving Object)

Player (Rigidbody2D)

By following these steps, you allow the platform's movement to directly influence the player's position, achieving the desired behavior.

Conclusion

By making the player a child of the moving platform, you ensure that the player moves seamlessly with the platform, enhancing the gameplay experience. This simple adjustment is often overlooked yet is crucial for creating responsive and engaging environments in your Unity games.

Now that you know how to make your player stick to a horizontally moving platform, you can create more interactive levels that provide a smoother experience for players!
