How to create a 3D side-scrolling game using Unity

If you’re an aspiring game developer looking to create a stunning 3D side-scrolling game, look no further than Unity. With its intuitive interface and vast array of tools and assets, Unity is the perfect platform for building games of all sizes and styles.

Setting Up Your Environment

Before you can start building your game, you need to set up your environment. This involves creating a new project in Unity and importing any assets you want to use in your game. Here are the steps you should follow:

1. Open Unity and create a new 3D project. You can do this by going to the “File” menu and selecting “New” from the dropdown.
2. Once your project is set up, you’ll need to import any assets you want to use in your game. This could include things like character models, backgrounds, and sound effects. To import an asset, simply go to the “Assets” menu and select “Import Package”.
3. Once you have all of your assets imported, you can start building your game by adding them to the scene. To do this, simply drag and drop them onto the canvas.

Creating Your Characters

Now that you have your environment set up, it’s time to create your characters. In a side-scrolling game, your main character is usually the player avatar. To create your player avatar, you’ll need to follow these steps:

4. First, you’ll need to create a new 3D object in your scene. You can do this by going to the “GameObject” menu and selecting “3D Object”. From here, you can choose the type of 3D object you want to create (e.g. cube, sphere, cylinder).
5. Once you have your 3D object created, you’ll need to add a mesh filter to it. This will allow you to attach a mesh (i.e. a 3D model) to the object. To do this, simply select the object in the hierarchy and go to the “Add Component” menu. From here, select “Mesh Filter”.
6. Now that you have your mesh filter added, you can attach a mesh to the object. To do this, go to the “Assets” menu and select “Import Package”. From here, you can import the 3D model you want to use for your character.
7. Once you have your 3D model imported, you can assign it to the mesh filter by dragging and dropping it onto the object in the scene.



8. Finally, you’ll need to add some animations to your character. To do this, go to the “Animator” menu and create a new animation clip. From here, you can import the animation data for your 3D model. Once you have your animation data imported, you can assign it to the animation clip by dragging and dropping it onto the clip in the animation window.

Adding Enemies

Now that you have your player avatar set up, it’s time to add some enemies to your game. In a side-scrolling game, enemies are usually stationary objects that the player must avoid or defeat. To create an enemy, you’ll need to follow these steps:

8. First, you’ll need to create a new 3D object in your scene. You can do this by going to the “GameObject” menu and selecting “3D Object”. From here, you can choose the type of 3D object you want to create (e.g. cube, sphere, cylinder).
9. Once you have your 3D object created, you’ll need to add a mesh filter to it. This will allow you to attach a mesh (i.e. a 3D model) to the object. To do this, simply select the object in the hierarchy and go to the “Add Component” menu. From here, select “Mesh Filter”.
10. Once you have your mesh filter added, you can attach a mesh to the object. To do this, go to the “Assets” menu and select “Import Package”. From here, you can import the 3D model you want to use for your enemy.
11. Once you have your 3D model imported, you can assign it to the mesh filter by dragging and dropping it onto the object in the scene.
