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 tutorials

Your post does not have a correct structure: Title is the most important thing, A title must explain in one sentence whats your problem about, so experts in that topic can enter to read the post, Inside post main body, you must explain When, Where, How, Why you problem occurs

Your question isnt 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
