You mean like, move loot bags/corpses physically upwards (against gravity) while playing the game, so as maybe to move them from where they drop to another location? Or “make them drop more often when a zed is killed so I can do testing of the base design”?
If “make them drop more often”: yep, you can mod that in. Or likely just drop the bags/zeds in from the slaw we or creative menu.
if “physically move upwards”: then the only options I can think of are:
- there is an elevator and a “rotatable bridge” mod by guppycur. Those may allow movement of stuff “upwards”?
- there was a YouTube series by ...jawoodle about building bases looking for cheesy things to do. One was making a “cannon like structure or tunnel “downwards” and at the bottom was a few steel? Bars with some space beneath them.He opened a hatch on the outside,threw a bunch of unlit grenades into it so they fell down into the lowest level , under the bars,then closed the hatch. Then, he spawned like 25 zombies right on the hole on top and they fell to the bottom, on top of the steel bars. He then quickly open the outside hatch, threw in a lit grenade, closed the outside hatch. When the grenade went off, it triggered all the other grenades, and it killed the zeds and also threw them upwards like 50+ blocks. So there is likely a way with explosives and properly shaped areas to fling things up on a semi repeatable way. But the explosives may do a lot of structure all damage, so you might have to mod the explosives to not do any block damage, or fine tune their “blast power” to make this useful.
As a side note: you’re fighting gravity. It might be easier to design for “catching” what you want in a funnel as bags drop/zeds die. Maybe a floor of hatches operated by a switch. When there are no alive zeds on the floor you open it and stuff falls below. Alternatively. I think jawoodle also tried mounting the vanilla sliding garage door flush with the floor and then could open it and stuff would fall that was on top of it.
