Spring RTS Engine

does anyone know how to move a model from a mod to another?
as an example, i want to move the core commander model from xta to another mod.how can i do this?

Um, just replace the file?

i tried that.only the arm commander get changed.i moved xta arm commander .3do and succeded.however the core commander have .3do and s3o.i moved both and still i got the old model.so, do i have to change any setting?

Open the core commander .fbi file and add .s3o to the end of the 'objectname' variable.

.s3o's neeed to have the extension, while 3do's are the default and thus you dont need to put the extension on.

ok.it work.the only problem now is

when the core commander shoot, the laser/dgun come out of its chest and his arm is targeting the air

That means the unit's script doesn't correspond to its model. Try to copy the CORCOM.COB file (it's in the scripts directory) and see if that fixes your problem.

ok.it work.the laser will come out from its hand.but when i use dgun and build command, the game will crash

You need a dgun sprite for the weapon, and a buildtree for building units.

here is the log before i copied xta commander script to a mod(well,i didnt want to copy the script because it cause the game to crash)

coberror: invalid piecenumber for show(flare) (in scripts/CORCOM.cob:fireprimary at 757

It doesn't work like that.

ok.i give up.no more editing.will play just the way it was meant to be, unless someone give me a good solution on how to edit it
