This is the whole error
Assets\Scripts\Combat\Fighter.cs(24,39): error CS1061: ‘Mover’ does not contain a definition for ‘Cancel’ and no accessible extension method ‘Cancel’ accepting a first argument of type ‘Mover’ could be found (are you missing a using directive or an assembly reference?)
I think the problem I keep on having are because I am doing the course out of order. I Googled and I can see that Mover is deriving from Fighter, which has Cancel, but Mover itself has no Cancel.
Does Cancel need to be in Mover, and if so, does it need to be above the method that calls it in the code?
