Day 2, a couple of new things! The game now generates connections between nodes. For a connection to be created, two stations need to be in a straight vertical, horizontal, or diagonal line, no matter how much the lines are away.
At this point it was getting a bit messy (for example, the "travel time" numbers clutter up the diagram a lot), so I spent some time cleaning up how the diagram looks, and add some rules to prevent too many connections from generating in busy spots.
Now the connection information will only appear on nodes you hover over with the cursor (although the tooltip is blocking some of that information currently, need to look at how to resolve that). Today's end result is this:
Finally, I made sure you can pass the time and have all lines indicate when the next train leaves (the upper number) as well as how frequently this train leaves (e.g. this train leaves every X minutes). It is still a bit cluttered, so I'm gonna look into how to present this nicely.
The player is now also on the grid, and my next priority is to have the player move around on the grid, and have that influence time properly. After that, I can start on the trading bit of the game!
