```
setColliders (x, y, side, index) {
// collider a
this.colliderA = this.scene.matter.add.circle(x - side * 150, y, 7, {
label: 'collider_a',
isStatic: true,
})
// collider b
this.colliderB = this.scene.matter.add.circle(x, y, 7, {
label: 'collider_b',
isStatic: true,
})
// collider basket
this.colliderBasket = this.scene.matter.add.rectangle(
x - side * 73,
y,
120,
30,
{
label: `Basket${index}`,
isStatic: true,
isSensor: true,
},
)
}
```
which function will remove them ?
