Post some ideas you got for Forge contraptions here
I wanna see if I can make landmines triggered by either traffic cones or pipe caps. Disturb them, they despawn, which sends a message to a fusion coil just beneath to spawn, and set THAT to blow up upon spawn.
A wall with a fusion coil next to/inside it. Shoot it, and it’ll despawn a chunk of the wall, and immediately spawn debris with normal physics that moves slightly away from the wall to get momentum for the regular physics to take over, to make it seem like chunks of the wall are being blown away.
