how do you create campaigns for single mode (with and without expansion)

you create campaigns then u place them under capaigns\ tag...

since I haven't modded for so long i forgot what exactly is the tag.....

but yeah..

Could you elaborate on your question? I have no idea what you're having trouble with.

Triggers... You use the Set Next Scenario action (or something like that). It's not modding at all...

I think he wants to replace the default campaigns with his own...

yes

I was going to post a topic on this too... but here are my questions:
Do you need to save the map as anything different?
Can you edit the number of missions?
How do you choose what video plays after what misson?

Look in the .mpq on the BW cd. It shows that you need to save your maps as .chks. The number of missions selectable missions cannot change, but you can have an infinite amount of maps as a campaign by use of Set Next Scenario. Notice how .wavs have a specific format too (as in their file name).

i found the maps but when i try to play them it doesn't play the maps i put in

Open your map in WinMPQ and extract the .chk file in it. Now put that into your mod's MPQ with the right folder location and make sure its for the right version of SC.

it worked
too bad i couldn't do it for StarCraft itself without the expansion

You can. Just get the right folder paths.

can you add more videos or is there any way to link them? In my mod im only having one campaign, and i have to use BroodWar, so could i use the terran, zerg, and protoss end videos all in one campaign?

I've never really delved deep into editting the videos, but I'm guessing its all hardcoded; so, unless you want to do some testing on your own to find the pointers to the videos, then well, your stuck with what you got
