Hi there! - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - If you're here to help me with the code, here's the problem: When the two items of the same type meet on the single conveyor belt at the same time, or in other words, same game tick, the items should stack on each other. < (for an example, iron + iron= iron x2) > The only problem it doesn't work perfectly. Sometimes it doesn't stack the items, probably due to uneven game tick of the items. Anyone who can manage to fix the code will be rewarded by me giving credits (@username) in the project instructions, and even within the game credits. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Thank you from the bottom of my heart for being here, and especially for reading the message to the end, thank you once again. - TinerX
