Unit Interaction - Movement Actions¶
Stop Action¶
This action stops the selected units from doing their currently active task (moving, gathering, attacking, etc.). It is also used to stop research in buildings.
Definition¶
def Stop
int8 :action_identifier
int8 :selection_count
array :selected_ids,
type => :int32,
initial_length => :selection_count
end
Description¶
:action_identifier
Always has the value 0x01.
:selection_count
The number of selected units. Is always 0x01 when stopping research in buildings, since AoC doesn’t show the building queue when multiple buildings are selected.
selected_ids
The IDs of the selected units. When stopping research, this is the ID of the building where the research is queued.
Examples¶
Stop a bunch of (moving) units.
