I'd want to alter a scenario map, so that I can set for players to have a different flag color than the default one - for example, Player 1 starts with Teal rather than Red.
Too late now but for single questions about the Editor, there are two existing threads, (one is my H5 beginner's guide)that I usually follow to help others.
Open map properties and you'll find the lines to edit players. Color is set to "default." and..."0" is player 1, "1" is 2 and so on.
