I've been thinking; why not implement Unit Queuing as a game option? Kind of like how you can enable Crates or Worms? That way the people that want it can have it while the people who don't want it can just ignore selecting that option. Don't know how to implement is for the main campaign or any pre-exisiting campaign but that can be future goal.
An actual bug I found was in the WoL missions, especially in Mission 2 for the Sardaukar: sometimes the "Missile Launch Detected" line might get switched with another random line or sound. I've had both gunfire and "the ordos are coming closer!" play when selecting the target for the nuke.
Non-code-based suggestions: Would it be possible to give the Smugglers a different colored tank and structures? I get they're Not Ordos but if you have them, Mercenaries and Ordos all on the same map its kind of a mess. The main issue I can see would be if a re-color was applied then it would affect anyone using an Ordos Tank thus making the change to begin with useless.
Then there's the Mercenary Tank. I think, haven't tried it yet, that this one suggestion could be done via the new map editor. Anyways I was thinking that it would make more sense for the Merc's to have the Atreides Tank. Both from a statistical perspective, since its the all-rounder combat tank, and from a visual perspective since the Merc Heavy Factory has that sloped roof...
If you only need the 1 picture of any building and or unit, on the path "Dune 2000\data\UI_GFX" there are many bmps containing the images on a magenta background easily removed.
If you need every single graphic in the raw value (units looking on multiple directions), then you need 2 things:
1: the resource editor, here:
2: open the file named "data.r16" (that it is on your game, on the "dune 2000/data" path) with that tool.
Inside you have every single graphic in the game for units and buildings you may need.
the program itself can export them, but there is an option to "export all" (it will do it into .png format) and will export every graphic so from that point you can just check the graphics directly withouth other tools (or simply export the graphic/s you need to edit individual png files with whatever image-edition program).
