There's no Slide() proc built into BYOND that I'm aware of, unless you're using someone else's source code.

Slide() is not a built-in procedure (well, not in the DM Ref anyways) therefore we would not know what it would be used for without seeing the code for that procedure.

animate_movement determines how objects are displayed while they're moving. There are a few settings for this:

FORWARD_STEPS - this is the default, objects will slide around using pixel movement if they are not required to move one tile per tick or more. They will not "cut corners" when they slide though, so as to not make them "slide" through walls visually.

SLIDE_STEPS - same as above, only they can cut corners.

SYNC_STEPS - this is used for multi-tile objects. See the DM Reference if you want further explanation on it.

NO_STEPS - with this setting objects will simply snap from one tile to the next with no smooth movement in between.

To set this var for an object, just do this:


Or set it at runtime:

You'd have to be a whole lot more specific about what you're doing if you expect a meaningful response to that.
