for the moment I have just 1 enemy. I have him in several parts of the stage so i multiplied it holding ctrl and moving it.
The thing is that if I select only one of them and change it's parameters the others won't change, only the one selected. If i select it on the project folder all of them are selected but the parameters in the behavior (in this case platform) will be erased and have to complete them all again which is a lot fo work. And it's also a problem deleting them all except for one where I'll change the parameters to copy it later. There have to be an easy way to do this but can't find it.
