But only allow 1 per a 1 chunk area around it

I think 2 chunks could be good but there would be a problem, some nations might put landmines underground so that enemies cant put em, also it will be the pain in the (family friendly) bum bums to remove and finding them from each chunk.

Also it could stun the enemy tank, truck, heavytank and any kind of ground vehicle for like 10-20 seconds, it would be like the same way a track gets blown up by a landmine and then the crew should repair it like IRL.

I like this idea Oliver. Furthermore, my idea for landmines so that it doesn't cause massive server lag is that they can only be placed during siege times and are automatically destroyed/despawned when the siege time ends.

I would like to mention you can build Redstone based land mines

Yeah but those don't work very well.

have you seen tnt minecart bombs?

combine that with a skulk sensor

This seems like something that would be either extremely overpowered and annoying as fuck or an absolutely useless gimmick, mainly I'm concerned about every block between each siege base being filled with them and making any type of push impossible (and also this would probably end up making sky bridges a thing). A chunk limit would be absolutely vital but that comes with glitches and exploits (placing tripwires underground to stop enemies from building cannons in certain chunks is an example of a current failing of that specific chunk limiting system when it comes to cannons, the mines still counting as being placed despite being destroyed is another problem with the tripwire limit.)

In a way, stalagmite traps and normal fortifications already fulfill this role and are decently easy to remove/destroy.

Also, anything that isn't either movecraft or a cannon that can counter movecraft is a bad idea and is equivalent to removing movecraft from the game, if these were to be added they REALLY should not do damage to movecraft as you would never be able to use tanks or ifvs at a siege again.

plant11 the minecart mines dont work anymore cuz tanks dont drag things under them after a certain update long ago

i remember when they worked. i planted like 300 sculk sensor landmines around my old enemy town named ''novgorod'' which doesnt exist anymore

these aren't for tanks these are for players

also if its just under you could put it on any terrain incline so its on the side

Nuh uh this seems like sth that will be a standard to spam near bases

That could get fixed easily by making it so that you cannot put mines atleast 2 chunks away from claims but could be used in sieges, also i think it could be a very neat thing to only stun movecraft rather than doing dmg to players.
