SpawnPoint Changer is a simple app that allows you to change your spawnpoint in your Minecraft worlds! All you have to do is open the program, select a world, and edit the spawnpoint coordinates. You can also select to set the spawnpoint as your player's current location in the world. So you can just walk into your house, save, then set the spawn to your location. This program only works for Beta worlds.
Note: You need to save your world and close Minecraft before you can change your spawn. Otherwise, it won't work.
Oh yeah. Your spawn reverts to original spot. Nice job on attempted smart-assery, though.
Have you verified this in-game?
It's reasonable behavior, but bed-spawn data is stored with each player, so a bed destroy event would need to scan the full player list in order to wipe the spawn. A quick glance at the 1.3 or 1.4 code suggests that this does not happen, but it could be buried in an obscure place or a recent change.
Um... I'm a map maker and find this to use about as useless as a fether in a sword fight.
MCEdit lets you easily set your spawn. SPC can set it to with /setspawn while standing where you want the spawn set.
BOTH let you SEE exactly where you're at. No need to write down coords then punch them into a little program.
Any map maker would have some sort of mod to help build the map, SPC/TMI being the most common. I don't see why anyone would need something like this to set their spawn when they could do it very easily and -SEE- where they are putting it to boot.
