Believe it or not, as a parameter modder I still cannot use the editors properly and I can find no comprehensive written instructions on how to use them. Well, I can use the external editor for compiling and debugging as per General WVPM's excellent instructions. However, extant written instructions for unit versus unit tests seem to be sketchy and incomplete. People tell me things verbally, I make notes and then I lose my notes. For example, all I want to do is test opposing units directly against each other, not in a game, yet I can find no way to do this in the editor (either editor). So I have to rely on games against the AI or observing what happens in multiplayer games. In the in-game editor, I can place units for red. I can see no way to swap player and place units for a second opposing player, say the one with flag blue. What is the way to do this? I can find no instructions which provide this simple and very necessary piece of information. Or is this not possible in the in-game editor? Can I make selected units (and selected formations) fight each other in the in-game editor or should I use the external editor? What are all the key instructions I need to know to do this? I would much appreciate comprehensive written instructions that list everything one needs to know for tests as above. I am afraid I am a person who absorbs information well from written sources but poorly from verbal instruction. This is unless I do what I did in my student days which was write copious lecture notes and then write them up again neatly later. I've not been that disciplined this time round. Any help would be much appreciated, thanks.
