I was just curious. I'm not 100% sure if the animations are there all the time with my mod... but then again, I DID write a new intercept logic, so I may have caused this myself. I need to spend a little more time testing, I guess. If it was a matter of: "Look up this code, if it's like this is broken, it needs to look like this!", then I could have more quickly checked it.
In my mod previous to the fix ALL FIGHTER INTERCEPT ANIMATIONS WERE BROKE.
This meant, if the AI had fighters on intercept, and I chose to fly a combat mission, you would see NO ANIMATION AT ALL... no bombers flying out, no fighters attacking the bombers... all that you would see is the TEXT comment on what happened (a text message saying the bomber did x-amount of damage and/or that the bomber was intercepted/shot-down).
That's what I mean by the fighter intercept animations were broke in my mod.
Mind you, if you were bombing an opponent who had NOTHING to counter you by means of intercept, the bombing animation worked just fine... but if the AI could counter you, you'd only get a TEXT message and no animation of anything at all.
Once again, if this is broke it is ALWAYS broke... you'll not see ANY intercept animations... so the bug is easy to spot if it exists at all (and it may or may not be in your mod, but so far as I know it was only in my mod).
The AI not bombing you if you have planes on an intercept mission is actually a completely separate/different bug all-together... they sound similar, but are actually independent bugs from one another... this latter bug is widespread, because it's a bug that lies in Solver's 0.19 patch which a lot of folks have based their mods on.
All you need to do is setup some test situations in the WB to see if either of these bugs are in your merged mod... you just need to take a few minutes to test it out... give the AI some planes in range (and in-sight) of your own city, start a war and set a fighter on intercept to see if it will intercept the AI, if you'll see animations of it, and/or if the AI will even sortie out (make sure he can see your cities and/or units so he has something to attack). Test it with and without your custom gamecore to see the difference.
I'm just glad all that is behind me now. All those bugs were identified, squashed and fixed!
