…ordered map from script name to enabled state, however this doesn't guarantee maintained order, causing script failure. An ordered map wouldn't work because it requires a comparison function, when the order needs to be determined by insertion order. It seems like it may as well be handled with a vector of script names, while maintaining the unordered map of script name to enabled state. However, each script name is recorded twice there (this is also what I have implemented, it works). Probably the best solution would be to just keep a vector of script name and a vector of corresponding enabled states, however the efficiency of searching goes from log of size to linear with position, which seems bad, but nothing should ever have enough scripts on it to be a problem, is what I imagine. Feels like I'm missing the optimal solution.

don't know enough c++ to comment on the technicalities but can confirm this keeps script order in-game by repeating steps in my mods that would previously break the order (and now they don't). @Causeless ? |

You could do a Might technically even be slightly faster as well, std::unordered_map performance is notoriously abysmal. Especially at these small entry numbers |

Previously, scripts were recorded with an unordered map from script name to enabled state, however this doesn't guarantee maintained order, causing script failure when behavior in the Create function (or elsewhere) of one script depends on the behavior of other scripts, which may be scheduled in certain circumstances to occur too late. An ordered map wouldn't work because it requires a comparison function, when the order needs to be determined by insertion order. It seems like it may as well be handled with a vector of script names, while maintaining the unordered map of script name to enabled state. However, each script name is recorded twice here (this is also what I have implemented, it works). It seems somehow less than ideal.
