Hi,

Me and my friend are starting to speedrun the coop mode (All main courses)

We are trying to find a way to practice each separate chamber, but we haven't found one yet. I think you have 2 commands to reset a run right? You can also reset the run by doing do_reset, but we are completely new to this so sorry for any misunderstandings. We follow the general coop tutorial series made by Airhead. But Any advice on running coop in general and on how to practice it, is welcome!

to practice individual chambers in coop, you can use the "changelevel" command. you may be used to using the "map" command for singleplayer but that doesnt work in coop because it puts you in a new session.

you can run the command "map_list" to see a list of maps to change to. the one you want is the file name, not the map name. or if you cant remember the map by just the name you can also look at this page on the wiki https://wiki.portal2.sr/List_of_Co-op_maps which has the same list but with a picture to more easily identify them.

if you wanted to go to doors, you would run the command "changelevel mp_coop_doors". replace mp_coop_doors with whatever file name you want for other maps.

yes, you can just use do_reset to reset a coop run. it does the same thing as locking the maps and taunts.
