Solved problem comparing itemstacks

when I am comparing a itemstack with another itemstack it won't work how I want it to.

code https://pastebin.com/a4WnTC4Z

I have tried comparing it with == and .equals neither worked the way I want. the way I want is for it to run if the itemstacks don't equal each other

 

Do you get errors? Does your event fire correctly?

 

@Tango_ it fires because I get the player.sendmsgs but they are given to me when they shouldn't be

edit: I need help I have no idea what to do

You rare forgetting to return after a condition is met. E.g if savedList is empty, you do not return to stop executing the rest of the code.

 

@yPedx that won't change my problem because even if I do return it just makes the loop exit earlier my problem is that when I try and see if the itemstack I get from event.getinventory.getitem(slot#) doesn't equals the other itemstack (that itemstack is just something that is given by a different class which is an api for a custom crafting inventory) but the if statement always runs now matter what even if the itemstacks equal each other


edit: the other itemstack was wrong and I fixed that so now everything is working except when I set the result slot the item I set in there doesn't show up
