✅Crash when changing bridge type

[DreamBuilder]

My game instantly crashes when i change bridge type on highways especially long ones

[Brody Craft]

that happens when theres too much things to process, also happens on weak devices

I was lazy when I implemented it. The code looks a bit like

Code: Select all

void setBridge(Road r, Bridge b) {
  r.bridge = b;
  for (Road _r neighbor of r with _r.bridge != b) {
    setBridge(_r, b);
  }
}

The problem here is that the function calls itself. For each function call within a function memory on the so called stack is needed. As stack size is most often not huge you should avoid too many function calls in other functions

Will be fixed in the next update.

The solution to such recursion problems is to use a queue of roads from which you remove roads until it's empty. For every road you might have to add new ones to the queue (neighbor roads), so you have to ensure that you don't add already processed roads again. Otherwise it will take a long long time:
