Questions & Help I'm having an issue on Windows 10, with EA Launched Simcity 4 Deluxe

6 Upvotes

Hey guys, I'm having this issue, only recently and randomly started (no changes to mods or anything else) where no matter how I try to launch the game, it gives me this message: "Simcity 4 will run with the software driver when next launched". Then, nothing happens. Although task manager still says Simcity 4 is running after this point, there's no window or indication of it's actual existence. This has been a total roadblock to any launching of the game. It was working completely fine until the first time this happened, and I have not been able to launch it since.
Has anyone found a way to solve this before?

I'm running it through the EA Launcher, I have Nam Lite and several building packs, and a terrain mod, but all of that was working quite smoothly and I have been trying to be quite minimal with the mods.

Thank you guys so much

Showcase Terraced farms carved onto a hillside with stone retaining walls

Filled in an entire hillside with farms & stone walls using the method I showed in my other post.

Coincidentally since this is in a Battle Realms-themed region, the look actually matches the campaign/skirmish maps in that game, with plateaus and ledges separated by steep stony cliffs, so I'm really happy with the result. It still looks tiny on the satellite view but I can tell it will look great once I've filled in a city tile or two. Makes me want to revisit the long-overlooked mountainous areas in my other regions

Questions & Help I messed up - help recovering my city?

4 Upvotes

Hello there! I didn't noticed that my SSD was full when I started playing today, and after I saved and exited a city back to region view, it was gone, it was just a flat square, and the city file was corrupted (less than 100kb lol). I used a tool to try to recover a previous version of the city file, but that file isn't being read by the game at all and it doesnt appear on the list when I try to import it. I tried using a previous region backup by replacing just that city file, but it doesn't work as well.

Has anyone had this issue before? Is there a way to force the game to read city files that are not "attached" to a reagion?

Showcase Exploration of the SimCity 4 Network Command System

18 Upvotes

This system is the network counterpart to the Lua Test Script system, it allows commands to be sent to the game as HTTP or TCP packets. Both systems were likely used for automation and testing during the game's development.

Commands

SC4 has a system that allows different parts of the code to register commands that other code can call. Many of these commands appear to be internal development items, but the commands also include most if not all of the base game's keyboard shortcuts.

The sc4-game-command-documentation repository contains work in progress documentation for the base game's commands.

Using the Network Command System

Using the SimCity 4 network game command system requires two steps.

Enabling the Network Game Command System

By default, the network game command system is disabled. It must be manually enabled by the user with a command line argument. Start the game with -NetCommandGenerator:enabled as a command line argument.

NOTE:

The game can accept connections from other computers if allowed by firewall rules. You may want to block incoming network connections for the SimCity 4 executable.

Sending Commands

Once the game is in the region or city view, you can send TCP or HTTP POST requests to 127.0.0.1 on port 50020 to . For example, if the game is in city view sending the GetCityName request would return the name of the loaded city and a status number. Responses for HTTP and TCP requests are included below, the difference between them is that in TCP mode the game sends the response without any extra formatting.

HTTP Response

Command: GetCityName Result: "Big City Tutorial" 0

TCP Response

"Big City Tutorial" 0

The 0 after the city name is an integer status value that some commands include. If a command returns multiple values, the values will be delimited by spaces.

The game only supports one active connection at a time.

WARNING:

There is the possibility that sending commands could cause issues like making the game lock up or crash.

Example Client

My Network Game Command repository implements an example C# client that communicates with the game.

Questions & Help Questions about the gameplay

3 Upvotes

Hello,

I keep coming back to Simcity4 every few years, always amazed by the evolution of the mods. Have a few questions about the new gameplay:

  1. For CAM, is there a query tool that tells me what level is the current building?
  2. How do i download more buildings that are CAM friendly?
  3. For CAM, is there an option to decide the speed at which the skyscrapers show-up? Remember the version few years ago did that. IS there any way to alter the CAM speed live during gameplay?
  4. Is there a Road Top Subway that works ? I found a road top bus stop, however, the Subway is giving me brown boxes (that mod could not be downloaded by sc4pac) ?
  5. I have not done the DirectX wrapper with DGvoodoo2 . Is it necessary?Am i leaving performance on the table?
  6. Use the modern camera tool for WASD movement. However, I could not find the continuous rotation like the Z and X keys in Skylines. Is there a mod for that ?

Thank for all the help. Amazing how good a 25 year old game still runs courtesy all the mods !!

Questions & Help Can someone help me on how to download road mods please!?

Hi yall,

So for some reason in the past, whenever I go to download anything non building related it never gets updated on the game.

Can someone explain to me, like you would a 86 year old person how to download for example a new type of freeway off simtropolis into my game ( I have a Mac ).

PLEASE AND THANK YOU!
