FPSControl and RPG Starter Kit conflict!

If you want to use both assets, there is nothing you can but but go through every line of code and change the Type names one by one (You only need to change the names for one of the assets, of course). It helps to search for Projectile, check if the current script that was found is from the asset you want to change, and then change it.

Oh, and one more thing: Make a backup iof your project before you do it.
