Unused variable '*' for Label for iOS

Do these warnings have an impact on game performance?

And how can I solve them?

thanks

I have about 76 of them, all old and deleted blocks of code that still show up like that and are still present in the file structure of my game. I've asked in another post why they are still hanging around, because they seem to be stopping my game form loading at the moment :-(

Custom Blocks in actor behaviours always have a local variable (aka parameter) referencing the actor (self)

In cases where you don't actually use that variable, you get the relative compiler warning of something not being used.

Don't think it has anything to do with performance or inability to compile or load.
