I've been looking for something to make and thought about making a bot to find people and wait for certain trigger words then reply with a response. Just something fun to watch also to see if anyone starts to have a conversation with a bot…
However I'm unsure what I can use for chat detection from the player. Any ideas please?

This function finds text between set lines in chat box:

IsChatBoxTextBetween(Text: string; TextCol, StartLine, EndLine: Integer)
