Hi $$anonymous$$rHero, can you post your code as text and format with the 101010 button, not as an image, thanks :)

Your code will only work if the _Player component is on the same game object as this script. And I second @$$anonymous$$rSoad's request. Please don't post scripts as images.

@$$anonymous$$rSoad: Thanks for the info.

@Jeff $$anonymous$$esselman: Ohh thanks !! one more question, so this script is attached to a prefab, what if i wanted to make another type of crate? it will still need the player script to be there? what if there is more than 50 different enemies will i have to attach my player script to all of them?

Thanks againn ^^

@robertbu yeh I'll do that, but what if i want it to run without _Player being a component of the script?

Ya you can do it By putting it on a single game object in scene and make this _Player class singleton.
