Problem in AirControl(Character)

Im kinda wondering about aircontrol

this function can control chara turn in the air while we set it at “1”
0 means no aircontrol so we cant turn in the air

(by the way im trying to reproduction Source Engine 's Movement logic in UE 5.7)

but im using cpp to override CMC component and i have my own way to calcvelocity
my main problem is : did aircontrol to have an effect even if i override the calcvelocity
or i have to rewrite AirControl

Hey, welcome to the forums.

AirControl is effecting the falling movement even if you override the CalcVelocity method.
PhysFalling() computes FallAcceleration first and then runs CalcVelocity() with the FallAcceleration as Acceleration.

If you want to change that, you can override GetFallingLateralAcceleration() or GetAirControl().
