[Question] With The New DLC Is It Necessary To Have Two Versions Of A Mod Available

[BillBobJoy]

If you want a mod to be usable to people to have the original game and the RoG DLC would the capable of interacting with DLC content be backwards compatible?

[squeek]

Here's what I'm using to detect if the DLC is enabled (IsDLCEnabled and the REIGN_OF_GIANTS constant are defined in dlcsupport.lua):

 

local is_rog_enabled = IsDLCEnabled ~= nil and IsDLCEnabled(REIGN_OF_GIANTS)

So, you won't need to make 2 different versions of the mod, but instead use different logic based on whether or not the DLC is enabled. It'll definitely make mods more complicated to support, especially after there have been a few DLCs.

Here's an example of what I do in my Trick-or-Treat mod to support both RoG's 4 seasons and the standard 2 seasons:

local hasfourseasons = IsDLCEnabled ~= nil and IsDLCEnabled(REIGN_OF_GIANTS)if (hasfourseasons and seasonmanager:IsAutumn()) or (not hasfourseasons and seasonmanager:IsSummer()) then  -- do stuffend

I see, so whenever a mod encounters something that could be different in the standard version and the DLC version just detect which they are running and have code for both cases.

Exactly.

We're hoping to add a way for modders to specify in the modinfo file if it's a main-game-only mod or a DLC-only mod or a mod that works with both! Even once we do add that flag, you'll quite possibly need to do some special casing using a IsDLCEnabled(REIGN_OF_GIANTS) call, as @squeek mentioned.
