How to pick up units of some category in a rectangle?

[Ghoustaq]

local units = GetUnitsInRect( rect):GetListOfUnits(categories.MOBILE, false, false)

the 'rect' here has been defined , don't worry about it

I am not sure if it is right to use two commands in one sentence?

That wont work, since GetListOfUnits has to be called on army brain
But something like this will do the job

Code: Select all

    local entities = GetUnitsInRect(rect)
    local units
    if entities then
        units = EntityCategoryFilterDown(category, entities)
    end

And if you want to get units only of a specific army, then there's function for that in ScenarioFramework.lua
