Sector_SetCurrent
From ZDoom Wiki
220:Sector_SetCurrent (tag, amount, angle, useline)
tag: Tag of affected sector amount: Strength of the current angle: Angle the current flows useline: Get strength and angle from the line instead?
Only valid during initialization. If useline is 1, this behaves just like BOOM's 225 linedef. If useline is 0, then the magnitude and angle parameters are used instead of the size and orientation of the line.
