# Create A Item

## Create Your Item Class
JavaScript:
```javascript
import { ActionResult, ItemSettings, CustomItem } from 'minecraft';

class MyItem extends CustomItem {
    constructor() {
        super(new ItemSettings().itemGroup('building_blocks').maxCount(16));
    }

    onUse(world, player, hand) {
        console.log('Item Use');
        return ActionResult.SUCCESS;
    }

    onUseOnBlock(world, blockPos, side, player, hand) {
        console.log('Item Use: Block ' + blockPos.toString());
        return ActionResult.SUCCESS;
    }

    onUseOnEntity(player, target, hand) {
        console.log('Item Use: Entity ' + target.toString());
        return ActionResult.SUCCESS;
    }
}
```

    }

    onUse(world: World, player: PlayerEntity, hand: Hand): ActionResult {
        console.log('Item Use');
        return ActionResult.SUCCESS;
    }

    onUseOnBlock(world: World, blockPos: Pos, side: Direction, player: PlayerEntity, hand: Hand): ActionResult {
        console.log('Item Use: Block ' + blockPos.toString());
        return ActionResult.SUCCESS;
    }

    onUseOnEntity(player: PlayerEntity, target: LivingEntity, hand: Hand): ActionResult {
        console.log('Item Use: Entity ' + target.toString());
        return ActionResult.SUCCESS;
    }
}
