Each component can have localization. If the generator steps on the component, the localization will be added to the event localization.
Travel:
Travel is defined by cardinal direction (i.e., "NW"), and tells the generator where a component can go from here on the grid.
Run Grid:
Set Tags:
"Set" allows you to set tags, which can be checked later with "has" to determine whether a component can proceed to another component. Each grid must have at least one tag set to START to tell the generator where to start. Otherwise, the tags are entirely arbitrary instructions to the generator about the state of generation. For example, you could tell the generator it is "raining" and later check to see whether it is raining before adding rain-specific localization.
Has Tags:
"Has:" checks to see if a component tag has previously been defined when the generator stepped on a prior component. If not, this component becomes impassable.
Not Tags:
Adding a tag to "Not" makes the component impassable if the tag has been applied previously by another component.
Remove Tags:
Any tag listed under "remove" will be deleted from previously set components after the generator steps on this component.
