Add an extra layer of realism with this simple tides simulation

This mod makes the sea level rise and fall. It can add a nice little touch of realism to your game.

Set the range and speed of tide change in the options menu and watch as the sea level rises and falls periodically.

I recommend leaving the settings as they are by default, or lower. Range is 5 and Speed is set to 1 which is a balanced setting. Personally I'd lower the speed even more.

If you go too crazy with speed and range the water can start acting up and swishing around all over the place so be careful.

If it gets out of hand juck click the reset button to bring it back to default then leave the simulation running for a while until things settle down. You can also use the Reset Water To Sea Level button from Extra Landscaping Tools or the Reset sea level to mid-tide point button in this mod's options menu.


"Use initial sea level as High Tide"
If this option is enabled, the initial(map default) sea level will be used as High Tide so your city doesnt flood upon installation. If you disable this checkbox, the initial(map default) sea level will be mid-tide.

"Use current sea level as reference point"
Click this button after changing sea level manually with Extra Landscaping Tools(ELT) to update the mod to new sea level.
(Press pause, change sea level manually, open options, click button, close options, unpause)

"Reset sea level to reference point"
Click this to reset sea-level to to your last tide reference point. This is the same as the button in ELT water tool. Use this if your water is going crazy or you've accidentally flooded your city.
(Press pause, optionally bring water level down manually with ELT, open options, click this button, close menu, unpause)

  • The original tide level for your current city is saved in the savegame, together with the reference point. So you need to save after you make some changes.

  • The tide only raises SEA LEVEL, water from water sources, rivers, or lakes is not affected. I repeat, only water in the SEA, resulting from SEA LEVEL is affected.

  • I made this with performance in mind, so the tide only updates once every 60 simulation frames. In my test map(empty map with no buildings at all) I had no loss of FPS whatsoever. If you have a large city you could test this on for me, let me know if you notice a decrease in FPS.

  • I haven't tested how this interacts with Tsunamis or Floods, so if you notice anything odd let me know pls.

As you can tell from my mods, I like adding this sort of little touches to the game... so if you like it too, great, if you dont, then don't download it, simple as :D

Using BonbonB's map created for this mod I really enjoyed myself but I did run into one rather fun issue: When the tide went out it exposed some large sandbars. I took the opportunity to build a flood wall around one of them to get some more land. The tide came in anyway (under the flood wall) and the game crashed. Not a big deal just interesting :) Thank you for the mod.

@Comtex, how about you change the mod‘s options. Or maybe watch the linked video. :steamfacepalm:

Finally, a map that takes full advantage of the tides. 7 months in the making.

@baronjutter: checkbox should now behave properly and also the other problem should be fixed now.

Hi all. Sorry for my long absence but some crazy shit has being going down in my life lately.
Anyway. I've updated this mod which was actually broken. It now remembers the actual original map tide across sessions, so when you reset to original it will actually work and this should also fix the progressively lower tide problem. Also increased the maximum range to 20 and fixed the buggy checkbox that kept reverting... BTW, you need to save the city in order for the tide information to persist to next session.

can we get a source one tied to rain? so we can simulate american rivers that flood and make levies important?

How well does this work with Real Time? Also Rainfall?

Love the idea of this mod but had to disable it eventually, same problems other people have: over time the sea level just creeps lower and lower. I turn off "Use initial sea level as High Tide" but it keeps re-enabling every time you load the city and the city/mod ends up forgetting what its "true" sea level is, which is slowly pushed down over time.
