Should robot position / motion persist when quit game vs quit to title?

[michthom 0]

Hi folks

 

(Complete noob warning)

If this is expected behaviour please treat me gently, but I've come here as I'd heard OC persists robot state over chunk unload/load and server quits / restarts.

 

I tried building a robot in Creative single player and running the following from the Lua prompt:

for i=1,1000 do robot.up() robot.down() end

I then tried various things to try to 'break' the persistence, and sure enough it works beautifully if I quit to title and resume.

But if I quit the Minecraft client entirely (CMD-Q on Mac) without dropping to the title screen first then I've seen the robot 'slip' upwards one block (but continue running), and I've also seen it throw errors or reboot on repeated attempts.

 

I've included what I hope is relevant information below, and I'm happy to file a bug with more if its warranted. However if this is expected (and I should avoid quitting - other than from the title screen) then please let me know.

because cmd-q kills the program, so it dont has time to propertly save. if you do this while saving, your world gets corrupted

Ah! Ok, thanks. I had assumed a Cmd-Q sent signals down through the code to shut down cleanly, but I'm happy to avoid doing that if it prevents weird behaviour / corruption in OC.

Avoiding this actually prevents weird behaviour/corruption in the whole minecraft^^
