'Is Trigger' toggle box greyed out

Questions & Answers
1

As the title makes clear, the 'Is Trigger box is greyed out on one of the levels I’m working on. The level was previously navigated using a 3rd person controller, but i deleted that and added a first person controller and now the player can’t open doors.

Any ideas why this is happening would be gratefully received

Thanks,

Is the door automatically open when you approach it?

In any case, your player is either missing collider or isn’t a Trigger. Your player GameObject must be a trigger to interact with other collider.

Just turn it on in your Collider Components (which ever that component it might be) on the Inspector window.
