Create and replace art assets for a mini-game

[jgbourque]

Why this task matters

These kinds of objects don’t necessarily have scripts or gameplay mechanics. They're just scenes that help decorate your level or add variety to the world and can help make the space feel more immersive.

Steps

Part 1: Explore a basic art asset

Open the 0_template_intro Scene
While in the template intro scene, follow these steps to explore how the rock object is built and use it as a guide:

1. Find the Rock in the Scene Tree. In the Scene Tree on the left, look for a node called Rock.
2. Open the the Rock Scene. Click the small scene icon (movie clapboard) next to the Rock node name. This opens the Rock’s own scene in a new tab in the editor.

Understand Its Structure
Inside the Rock scene you’ll see:

1. A StaticBody2D as the root or parent node (this makes it a solid, unmoving object).
2. A Sprite2D child node that holds the image.
3. A CollisionShape2D child node that defines the object’s solid area.

Part 2: Create Your Own Game Object
Want to make a decorative item like a tree, bush, or a house? Here's how to build it from scratch:

1. Open a new blank scene in the editor. Click the “+” icon at the top of the Viewport to make a new scene.

2. Add your root node first. In the empty Scene Tree, select Other Node, then choose or search for StaticBody2D and click Create.

3. Add two child nodes under the StaticBody2D. Add these node by selecting your StaticBody2D node in the Scene Tree, then clicking the "+" button in the top of the Scene Tree to search for and add a new node. Do this two times: once to add a Sprite 2D (this will hold the objects texture) and once a CollisionShape2D (This will make the objection have a solid body). Your Scene Tree should match the rock.tscn from the intro scene.

4. Add your own texture to the scene. In the Inspector, drag your .png image from the FileSystem into the Texture property of the Sprite2D node.

6. Set up a collision shape. Select the CollisionShape2D node. In the Inspector, click the shape drop-down and choose a shape like RectangleShape2D or CapsuleShape2D. Resize and position it to fit the image in a way that suits your design.

7. Save Your Object. Save your scene and name it something like tree.tscn, rock_variant.tscn, or new_house.tscn.
8. You've now made a re-usable object! To re-use this new object, simply find your newly saved .tscn in the FileSystem and drag it into a mini game or scene and place it wherever you want. You can do this as many times as you want to add multiple instances of the object.

Additional Tips

• Use consistent scale so your object fits well with others in the game world.
• To use the object in a level, drag it from the FileSystem into your game scene.
• Want it to be decorative and not block movement? Use Node2D instead of StaticBody2D, and skip the CollisionShape2D.
