: like I said, this is trivial to do using sub-classing, so need to touch geo.nas at all - just create your own geo.Coord sub-class and add helpers for getting the corresponding properties via props.nas --[[User:Hooray|Hooray]] ([[User talk:Hooray|talk]]) 17:55, 29 October 2014 (UTC) | : like I said, this is trivial to do using sub-classing, so need to touch geo.nas at all - just create your own geo.Coord sub-class and add helpers for getting the corresponding properties via props.nas --[[User:Hooray|Hooray]] ([[User talk:Hooray|talk]]) 17:55, 29 October 2014 (UTC) | ||
Progress for tonight as follows. I've created missile.nas and ai.nas, both in $FGDATA/Nasal, with the code as follows. | |||
ai.nas: | |||

PS Hooary, how do you sub-class an existing Nasal class? | |||
