There is a problem with the Unity I am using. Whenever I go to enter play mode, it tells me “All compiler errors have to be fixed before you can enter playmode”. Any ideas on how to fix this?
It’s not a problem with Unity; it just means there are errors in your code.
Open the console, double-click on the errors one by one, and fix them. Once all the errors have been fixed, you should be able to enter play mode.
Okay. I opened the console, and it gave me a list of errors. But when I double-click on them, nothing happens.
Try reading the errors, that’s usually a good start. It will say what the error is. Read the error, fix the error. The problem isn’t Unity, it’s you.
Open the preferences window (Edit->Preferences…). What do you have selected for ‘External Script Editor’?
When you double-click on an error, whatever application you have selected there should open. If it’s MonoDevelop, it may take a little while to open (in my experience), so in that case, give it some time and see what happens.
