dMZX Forums: possible bug (new robot id issued after robitic save game) -> Archived MegaZeux Bugs -> Tracker

I'm not sure if this is a bug, or intentional, or if it's never been an issue before, but it's causing some problems in my game so here goes.
if I save my game through robotic, the number of robots that are on the board reorders a little if any robots have died. The robot count goes down by the number of robots that are no longer present on board. so in my instance, the robot that was running a program controlling sprite 66 was robot id 66 before saving my game, even if two other robots had died. After saving my game, that robots id was 63, it was still running a program controlling sprite 66. same program, different robot. I verified this through the debugger, (F11). I exported the before and after's to text files, if you want to look at those. Like I said, not sure if this is a bug, it just seems like it is to me. Thanks for looking into this, Graham.

I dunno if it's undesirable or not, but I ran into that one when making Lochronotran(prompting numerous bugfix versions). I have to say, it seems pretty silly that the ID changes when saved, but it aint hard to circumvent, but still doesn't seem to have much of a reason to do that. I could be TOTALLY wrong though.

Not a bug, changing it would require altering the file format to allow for null robots, don't assume any robot_id will be valid for more than the cycle in which you checked it. It's really an internal MZX thing that is exposed because it's necessary to be able to uniquely identify a robot- I think 'packing' them on saving is a reasonable thing to do.

If the documentation around robot_id doesn't already say this it probably should, because it would be a bit of an unpleasant surprise.

Updating status to: Flagged For Future Version
Updating severity to: 1 - Low
Updating Introduced In Version to: <2.80

It'd be a pretty basic change to the file format and doesn't hurt anything. This was probably going to happen anyway because of the nature of 2.85's major format overhaul.

Until then, follow Lancer's advice and I'll see about the help file
