THere are contradicting information on this topic.
Whenever I ask ingame it's either a "They need to stay still", "firing increases detection range" and so on.
I'm not complaining that he hit me, cause a Tirpitz was homing in anyway, just the fact that he was moving, while firing at very close range.
But thanks anyway for your kind reply.
Spoon posted already the sheet with the Invisifiring ranges.
Ideally, a DD should slow down to ~50% before popping the smoke when sailing parallel to the enemy, as the smoke is layed in clouds every 5 seconds.
When you can see them pop in and out of visibilty while laying a smoke screen, they are moving to fast.
When sailing away from the enemy, the DD can keep full speed as the smoke is layed behing him.
Some players will drive slowly forward and backward in the smoke screen, first off to avoid possible blind shots fired into the smoke and more importantly, to avoid getting torped.
Can't speak for others, but it helps me a lot to check what DDs are on the enemy team, and follow the battle progression.
Which DD got already nailed, and which is still alive.
While i do not actively steer my ship in every smoke screen i can find, i tend to do so under certain circumstances.
If i see a smoke screen ahead and a wave of torps just came out of it, i check which of the DDs is still in play.
Recently, i had a game where two DDs were still alive, a Shimakaze and a Fletcher.
A quick peek on the minimap revealed that the Fletcher was far away running from our CAs, while the Shima was nowhere to be seen until the smoke screen popped up.
I managed to dodge the waves of torps (apart from one ) and i knew the Shima has to wait until the Torps reload.
Because the screen was nearby, i headed straight into the screen and while my salvo didn't kill him, i managed to ram him.
Would there have been more DDs on the enmy team left, i would have turned away from the screen, as sometimes, and this is more common when DDs are in Divisions, they share each others smokescreens which prolongs the time they can hide, to either invisifire or spam torps.
