don't use removeChild/addChild in switchAsset, instead just change visibility
User prompt
store previous direction, and only switch if direction change

Don't self.attachAsset inside move function that's bad for perf. instead 1) pre-create a list of assets for each direction 2) create a function to switch the asset 3) call that function in move depending on the move
User prompt
3. **Dynamic Asset Switching**: In the knight's movement function, dynamically switch the knight's graphical asset based on the current movement direction. This can be done by detaching the current asset and attaching the new one corresponding to the direction.

Let's go step by step : in Knight 2. **Direction Mapping**: Create a mapping between movement directions and the corresponding asset identifiers. For example: - `'down-left'` maps to `dir1` - `'left'` maps to `dir2` - `'up-left'` maps to `dir3` - `'up'` maps to `dir4` - `'up-right'` maps to `dir5` - `'right'` maps to `dir6` - `'down-right'` maps to `dir7` - `'down'` maps to `dir8`
