What is the difference between a campaign script and a background script?
thanks

From what I've heard, a Campaign script runs automatically upon the start of the campaign. This is what the Prologue uses. The drawback is that you cannot save the game while the Campaign script is running.

A Background script is a Show Me How script, I think.

you can't save? how come i can save using R.S and etc.?

[Rasui Runihura]

What is RS? Roma Sect? You can save during a background/showme script, but not during a campaign script. I assume that, if R.S. does use a campaign script, they use it to activate a showme script... so that you can still save.

[Starvin Marvin]

yeah it is the show_me how, my bad, so what is the point of a campiagn script?

To script stuff automatically at the start of a campaign, or run a prologue type campaign.

A campaign script is used for 2 things:

- To script certain things that should only happen once (i.e. at the beginning of a new campaign). For example, adjusting starting funds, setting traits, killing off certain family members, and spawning additional starting armies.
- To automatically start the background script (when you create a new campaign)

Sorry for bumping this, but are there any other differences between them? (besides what was already mentioned)

Does one offer more possibilities then the other?

There is nothing that a campaign script can do that a background script cannot. Given the limitations of campaign scripts, you'd almost never want to use one for anything other then to kick off a background script.

Some mods do more exotic things in the campaign script, but that's rather unusual.

For example, the ExRM mod uses its campaign script to set the UnitSize trait (that's later used by the Spoils of War script, which is a part the background script), based on the ratio of the starting population to the starting garrison size.

Hm what about this.

Campaign scripts are also good for AI start balancing, as XGM does. But, yes, there are few reasons to use a large campaign script versus a background script.
