Bukkit

A have it set up 17 floors .
1 button set up on floor 1 to send it to floor 12,
and another set up on floor 1 to sent it to floor 16,
and another set up on floor 1 to call it back to floor 1.
Also I have a button on every floor to call it set up .

I stand at ground level which is what floor 1 is and i press the button to send it to floor 12 while staying on floor 1 and watching it go up . It does as it should and arrives at floor 12 perfect so i press the button to send it to floor 16 while standing on floor 1 and watching. All is good it makes it to floor 16 just right perfect .

So I press the button to call it back to me floor 1 and it comes down to me and stays there for a few seconds then goes all the way up to floor 17 by its self with out me pressing anything .

I have been testing this on my personal gaming rig at my house testing it out .
I have a intel core i7 4960X for cpu two nvidia titans for the gpus,
and 32gb 1600mhz ddr3 ram,
and a rampage 5 extreme for the motherboard,
and last 2 samsung 500gb ssds in raid 0 with 6 2tb drives in raid 10 .

So i have no idea how im getting this http://pastebin.com/84puiuGN

Are you sure you haven't accidently given the button two functions (moving to floor one and moving to floor 17)? You can add several movement commands to one button which will be executed in a row. To be sure, delete your button (destroy it once, this will remove the elevator functions but won't remove the button) and assign your movement command to floor 1 again. If it's still happening then, it might be a bug.

To your overload issue: This is depending on how big an elevator is and how fast a single of your CPU cores are. Elevator movement has to be executed in the server's main thread and will therefore only use one of your CPU's cores. Building smaller elevators will prevent this. But, 30ms CPU load is not that bad, you should still have a stable server tick rate.

I am going to create a new one man and test it again ! I may have like you said given 1 button more then 1 function . So I will start all over again . The one elevator you see in the picture took me right at two hours to make . I thought it looked nice . Oh and one last thing I know you have plans on permissions and I know that is a must because you defiantly don't want players going all over the place making elevators .

The sad thing is I have my intel 6 core running @ 4.9ghz and if my gaming computer is struggling a server with much lower cpu speed is going to be much worse that's why permissions is going to be so important . I know one thing man I believe if mojang and or bukkit , but mostly mojang don't do something about the game as in make it multi threaded then the game is going to be limited on what plugins can do.

I don't understand why they didn't make it multi threaded in the beginning . I mean you might as well take advantage of the multi threading capabilities of pcs now days . Anyways I am testing some more now . Thanks for the opportunity to test out such a wonderful plugin . This defiantly will bring life back into the game . Again I hope to be a long term tester for your plugin or anymore you may make and want testing done to .

I have been learning java myself ! To be honest its not hard but me knowing php,javascript,html and css helps a lot to so . I might make a few plugins for my server down the road but they want be public though . Mainly only going to make a more compact essentials plugin with only features i want . Thanks again man . Joe
