If I am working with a team member in sourcetree and we are working in 2 completely different areas such as me working with scripts and he works on scenes/art in unity. Say that he commits and pushes his changes and I see that I can pull them but I want to commit and push some of my script changes so he can use the scripts I made (example being out of 10 scripts I can commit and push I only want to commit 2 and push those 2). Do I need to commit everything I have at the moment even if it isn't finished to pull his changes just so I can push my 2 scripts that I need to send even though this way I would be pushing my scripts that are not even done yet?
I am a complete noob when it comes to source control and so is my team member and I really don't want to mess anything up but it seems like this process might be wrong but this is what the team member is advocating we do. I feel like I should be able to commit and push those 2 scripts without having to commit all of the other scripts that are not finished yet.
