guys i do not know how to destroy a box and make the box give points how i make that(death match)
you could try like
The trigger will be : when a unit gets attacked
if (( unit type of ( last attacking unit ) )) == (unit)
then do:
if (( unit type of ( last attacked unit ) )) == (box)
then do:
set points of ( owner of ( last attacking unit ) ) as ((( points of ( owner of ( last attacking unit ) ) )) + (1))
destroy ( last attacked unit )
