How to make a province system Grand Strategy-like games?

[WolfDeaS081]

I’m making a game where there is an interactive map with clickable regions like in Hearts of Iron or other Paradox games

There, a separate map is used for province boundaries, and another file stores RGB values about each province.

My problem is, how do I implement the provinces system? I made it so that when I hover the cursor, the game recognizes which colour it is hovering over. Now I can’t figure out how to make the provinces system itself so that the provinces are visually displayed. That is, perhaps some sort of zone system. I do not need to do it in the games Paradox, I would at least make the province itself, ie visual zone.

Generation of random country borders (maybe Voronoi?)

Hey man, that’s a great approach, and thanks for even taking the time to prepare and send me a project! It works pretty well for randomization. I was wondering how I could “select” a country during gameplay if I don’t have access to the color palette in the Blueprints. But I guess since it is on world coordinates it would be possible to - as you said - feed the cursor location into the material, grab the color underneath it and compare it to the color of the pattern as a whole gut get the cel…

Tutorial : Create Your Own Interactive Map With Clickable Regions

Hello guys ! I have created a series of 6 videos dedicated to the creation of an Interactive Map in Unreal Engine, with clickable regions, like in a strategy game. Before coming to this, I had searched on the internet how to do it. By grouping leads and thinking I succeeded. As there is no tutorial on UE from A to Z on this subject, finally… hum hum, it is now the case. I share it with you! Sorry for my English, I’m a frog. By the way, all my tutorial videos are subtitled in english. Example …

Yes, even though I’ve looked at all these articles. Specifically the first article where you clearly showed how to make the regions selectable and uploaded the project itself, I think can help. At least at first glance, thank you very much, apparently I missed something in my search.

Happy new year!
