[RA]Support for custom missions
Add support for custom missions with file name CMU01EA.INI up to CMU999EA.INI. The map needs OneTimeOnly=true else after completing the mission the game will crash trying to load map.
I'm working on this as part of the missions menu dialog revamp.
I'd prefer a solution that keeps custom campaigns self contained, like subfolders of a campaigns folder get enumerated as campaigns that progress, a folder called missions get enumerated as standalone missions and can be named *.INI to get enumerated. Something like that.
I'm okay with a special subfolder for missions. The CnCnet RA Patch and Nyerguds' TD patch add a map keyword for minicampaign support, including what the next filename is in the campaign (next map).
I'm working on this.
My patch doesn't add a map keyword for minicampaign support. It just makes the SC?##EA missions from the New Missions menu continue on to their EB, EC, etc variants.
