It’s from the old Shang-Chi map that we did back in 2021. It was only up for 6 months or so. Here’s the code for that block and gravity jump.

namespace sprites {

```
 /**
 * Allow your sprite to jump and come back to the ground
 * before jumping again
 */
//% block="make $thisSprite=variables_get(mySprite) gravity jump"
export function gravity_jump (thisSprite: Sprite) {
    if (thisSprite.isHittingTile(CollisionDirection.Bottom)) {
        thisSprite.vy = -200
    }
}

/**
 * Direct sprite to automatically jump only when hitting
 * a wall to the right or left
 */
//% block="make $thisSprite=variables_get(mySprite) hurdle side wall"
export function wall_jump (thisSprite: Sprite) {
    if (thisSprite.isHittingTile(CollisionDirection.Left) || thisSprite.isHittingTile(CollisionDirection.Right)) {
        sprites.gravity_jump(thisSprite)
    }
}

```

}

It allows your enemy to detect that there’s a barrier in front of it and attempt to jump that barrier. It’s really best for swarms of enemies that are trying to follow the main character.
