The forums are not here to simpstateyou to say what you want and just dump code. If you have a problem then please clearly state what it is and what you’ve tried to rectify it. If you want help in implementing something specific then state what part you’re struggling with.
There’s loads of tutorials out there showing this very common feature too.
When posting code, don’t use plain text, please use code-tags . You can edit your post to include these too.
