OK, so i have attempted to add the clone assassin to my map as an extra unit, and not replacing another. However it does not seem to show up in my map. I think i may have gotten myself confused along the way between replacing a unit and adding an extra.

Will i still need to set-up a parent ODF?

Below are some documents that may help clear this up

Repshell.req:
Level LUA I also added:

AddUnitClass(REP, "rep_inf_clone_assassin",1,4)

The guides here have helped me most of the way, just this last step has confused me!

Any help would be awesome

You can delete this line and you can also delete the repshell.req file; you don't even need it. What is important is the rep.req. You need to add the Clone Assassin to it and make the unit a .req as well which goes in your side's REQ folder. Look at the other .reqs in that folder for reference.

He's already in the rep.req, and here is his .req which was already in data_TSD\Sides\rep\req

Post all the ODFs pertaining to the Clone Assassin and an error log too if you could. Where exactly did you place this line in your .lua?

OK, all ODFs are below:

com_assassin_default:
com_weap_inf_vibroblade:
rep_inf_clone_assassin: The line is in my LUA under the set hero class lines.

I now have mace windu appearing in my map for some reason.

That first statement is directly related to the second. All your units need to be added before your hero, otherwise you will see what happens here - your hero will show up in your selection list, although when you spawn as the hero he will still have the hero bar etc.

OK, so i played through my map and some interesting things happened. After i accumulated some points, it told me i unlocked mace windu, even though he was already unlocked. When at the screen to select mace, the sillouette of the clone assassin appeared, then dissappeared after i selected mace again. I then was able to select the assassin after achieving 20 points.

The mose common errors in my error log (no severity 3's though):
EDIT - Just saw Mav's comment, so i want this instead?:

Yes.

All fixed now, thank you all for your help.
