I thought of a possible solution to make world ownership easier. That would be the /wlimit command!
Using this command, world owners could make limits on how much of each block a player can place.
The command would work like this...
/wlimit "Item Name" (number)
(A few players suggested that item ID's could also work for this)
Ex: /wlimit "Micro Protector" 5 (players can only place 5 micro protectors) — /wlimit "Exploder" 0 (players can place absolutely no exploders) — /wlimit "Plug" 0 (players can place absolutely no plugs) — /wlimit "Electric Bomb" 3 (players can only place 3 electric bombs at a time. They can't place any more until the three are destroyed)
Entering 0 into the command would prevent players from placing that item at all. Of course, the world owner wouldn't be affected by these limits.
Entering "Reset" into the command would remove a limit.
This command could be used to stop lag machines (disabling exploders), stop protector spam, prevent maws from being plugged, et cetera.
These limits could be set any time, and blocks placed before limits were enforced would not be affected.
I'll give a few scenarios on how this command could be useful...
— Stopping lag machines. Players could put a limit on or completely prevent exploders being placed.
— Building Competitions. The world owner can let the participants only use certain blocks, and limit the amount of protectors they can place.
— Keeping the world clean. The world owner can put limits on certain blocks like earth to minimize block spam. They could also disable self-protecting objects, such as spawners, inhibitors, and pandora boxes. The world owner could restrict/minimalize the placement of pets. Prevent other guilds from placing their obelisk in your world. Prevent/limit certain bombs. Just keeping the unwanted out of their worlds.
That's just about it. What are your thoughts on this idea?
