### **Sprite Walls Engine – Extension**
**Sprite Walls Engine** is an extension that allows you to use sprites as walls instead of tiles. It also includes a pushable sprite block, that lets you, well push sprites.
* * *
## **Features**
- **Sprite-Based Collision** – Use sprites as solid walls.
- **Pushable Objects** – Create objects that can be pushed by the player or other sprites.
- **Versatile Sprite Interaction** – Works with both individual sprites and `SpriteKind` groups.
* * *
## **How It Works**
This extension uses **AABB (Axis-Aligned Bounding Box) collision detection** to determine when a sprite collides with another. When a collision is detected, it stops movement or applies pushable the other sprite.
**Example Use Cases:**
- Walls that are not tied to tilemaps.
- Moveable crates or objects in puzzle games.
- Dynamic barriers that can be repositioned during gameplay.
* * *
## **Blocks**
- `stop (spriteA) when colliding with (spriteB)`
- `allow (spriteA) to push (spriteB)`
* * *
1. **How to use:**
2. **Add Collision Blocks:**
3. **Lastly**

oops, must have been a glitched file. reinstalled the extension in another editor and it works. but earlier when I had it on the enemies would not push the player, they were being pulled towards by the follow block. I don’t know what the error must have been, but it appears to be gone now.

I also found a new error, that being whenever I make a sprite collide with its own sprite type It just goes off screen. just fly’s away.

Okay, I have updated and fixed it now. just update the extension by opening javascript. open the explorer and scroll down until you find my extension and then press the update button.

Is this mainly for top-down or platforming games?
