Alright then. :P

at the start of the game one has to create a function in the entry point that checks whether building requirements are met. If they are then enable building. For original content this is hardcoded. You can tie this check to any building for example wizard guild but then any mod that changes wizard guild logic won't be compatible with this mod. If I tie this to palace then this mod won't work with my AI mod and so on.

These towers are situational. All of mod stuff is. Their sheer damage output is not scaled only by price. fire and poison tower best for trading posts/outposts, frost agains huge waves, lighting as a defender etc. I'm trying to keep things as balanced as possible. And to keep compatibility with other mods.

Mod is in good state as it is. Changing unnecessary stuff like build rate will lead to changing many other stuff that depend on this build rate. And the result really won't matter that much. So I say don't touch what works okay :P

But what do you have to modify to make the towers require the guild? Thats what confuses me. I thought the building simply had something in it that told it what was required to exist first. I feel that for the price you pay for these towers, they are rather weak. If only you could make their magic build method slower, like 1 HP instead of 5, then you wouldn't need to increase the price so much.

more buildings/more heroes, majestic majesty, some ivas mod, something else. But really it depends on the activation order in the mod menu. The last mod activated would override any functionality with the same signature like function name or data.
The problem is that there is a single point of entry for modders to check some stuff at the beginning of quest/mod. And that entry is overriden by last activated mod or quest.

What mods would break if you made them require the wizard guild? :P

Yes, they are. To make it work like original would break the compatibility with other mods. Therefore higher price and you still can't enchant without lvl 2 guild. The cost is somewhat as if you'd build wizards guild close to enemies to cast magic.

These are buildable without wizard guild and have no range restriction on them it seems. :P I have a castle level 1 on a new start and noticed that they are buildable even then.

Ah, so that mod works with this one too? That'll work too.

Because some people would want just the increased duration without having new unbalanced wizard towers in their game :)

Why separate though? Just curious. Since I know options are a thing and all.

Done as a separate mod, your Majesty!

By the way. Any chance of a version of this with a 10x higher enchantment duration or even 100x? I mean you could combine it into one mod with options like others do. I've always found the duration to be crappy. Might be nice to have 10x more duration with 5x the cost, or 100x the duration with 25x the cost. (Plus a "cheat" version with 1000x duration that costs 1x)

On my way, your Majesty!

Good! Now make me a sandwich! >:|

That is actually better. Missed that. Renamed towers :P

Why not just prefix them all with Wizard so they all stay at the end of the list like before? :P

Wizard Poison Tower
Wizard Lightning Tower
Etc.

I wish I could. But modders can only use red, green or gray overlay with varying level of transparency.

Cool stuff! Why not make frost tower bluish?
