Hello. You didnt ask any specyfic question. We will not read your code to try to find if something is wrong. you must know whats happening, where is happening, and then come to ask how to achieve what you pretend to do…

Some reasons for getting a post rejected:

There exists duplicate questions with answers if you were to do a search, either on Answers or on the Forum or on Unity's tutorials

Your question isn't specific enough: asking for a script, asking multiple questions in one post or asking a question that could be either subjective or require extensive discussion

Your question is about very basic issues, that can be learned just by searching in google or in multiple basic tutorials for begginers
