Limited amount of items?

Prussia13 · August 23, 2013

I need something where the player can only pick up a certain number of items at a time, like 10 (doesn't matter how many of each), but has to discard an item to pick up another--which I already evented.

I just need a script or a way to event where you can only have a set number of items in inventory or you can't pick up more stuff.

Can anyone help me? Thanks!

I use an item weight script to prevent people from carrying to much and a script made by bigace to allow people to drop items if they are overweight. The weight script makes it so the player cant move till they drop something.

Might want to use a translator for this weight script.

bigaces drop item.
