Getting an Object's or Fleet's Current movement left???

That is how fast it can currently go, not how much movement is left.

To get a fleet's max movement, you would need to do a search through all of the space objects in that fleet, and find the one with the lowest max movement.

I don't think there is a way to get remaining movement, but I could be wrong.

Couldn't you do a compare on the distance to destination and the computed movement points for the ship by component (since it only gives max). I know most mod functions don't work in the script portion so I don't think you can use those.

hhmm, I think you would have to set a bunch of constants for the ship size versus engine movement, but that gets messy and tedious.

Sys_Get_Vehicle_Design_Space_Movement will give the space movement by design...Sys_Get_Space_Object_Maximum_Movement gives the current object...Sys_Get_System_Distance_Between_Solar_Systems will give the distance in a weird value, not sure if thats what your looking for...
If I see something I'll post it here for you

Not too many AI modders around, Kwok, Gideon and yourself seem the bulk of them (limited resource pool...)

As Gideon suggested is how I did in the Balance Mod.

Try using Sys_Get_Hex_Distance_Between_Sectors to get the distance between two...uhhh...sectors.
