the player should be allowed to set up hidden sub-priority levels

[Gwido]

Sometimes, it's really annoying to see duplicants do a job before another because of some hidden sub-priority. For example, building pipes before walls, pick-up one material instead of another one.

 

We have priority levels to manage this in some case, but, for example, if I want to set up the construction of 2 rooms, but need that my duplicants build one before the second, it's not always possible to set up every priority levels. And it's better to just give a highest priority on all building errands for the first room.

We could also want auto-sweepers to pick up one type of material prior to another one, in a room. For example, storing oxylite before supplying gold to the refinery.

 

To solve this problem, I suggest to "steal" an idea from an old game : The Settlers 2.

This game had a simple system, where the player can set up priority for the transport of each material :

Not really complicated, we just had to move the icons up or down to respectively increase or lower the priority.

This could be included in ONI, to manage the sub-priority, so that it would be set according to the player's preferences, instead of dev's preferences.
