I could hold it but when I added the scripts to throw it I couldn't carry it any more. Also, how can you make it so you can only use the item once?

Do you mean like being able to throw a Sprite so it behaves like a ball?

yeah like a ball but one that the player is holding

the sprite I mean

Only using an item once is just a case of having a variable to keep track of whether it has been used or not. Eg set a variable ‘key-used’ to 0 initially and to 1 when it is used. Only allow it to be used when the variable is 0.

Ohh, you mean like collecting items with the player so you can throw them, like when pressing E?

I'm confused.

Do you want it to be thrown at something?
