how do pros instantly attack multiple targets at once in their mineral line? example: 4 lings run into mineral line and the scvs surround the lings and instantly start attacking all of them at once.

if 4 lings run into my mineral line and i select all my scvs and tell them to attack a ling, they will all try to attack only that single ling. 1 or maybe 2 scvs will actually be hitting the ling while the other scvs scurry about doing nothing and getting picked off while trying to get to the 1 ling I targeted.

teach please.

just attack area don't select any units just the position on the map near where they are

ah I see. I never realized worker units would attack on their own when you attack move.

ya workers can attack move

pro tip:

Say you run lings into some guys mineral line and he brings some zealots. If he doesn't a move his workers, your lings will prioritize zealots.

How to still rape some probes instead of having your lings run around and die?

click hold position. Zealots will kill 1 ling at a time while your lings just stay spread out and stationary and rape down some probes.
