how to get current acceleration?

Development Programming & Scripting Blueprint
1

hello, i’m trying to get the current acceleration for the vehicle movement component, but didn’t find how to get it?

any help will be very useful.

Well, I don’t know if it’s implemented, but you can always get the acceleration if you save the velocity v1 in the tick-event to a variable and take the new velocity v2 and the delta time dt and calculate a = (v2-v1)/dt.

thank you @ThiloN1987

Thanks for the input. This is not acceleration though? If you are moving with no change in velocity, with this blueprint you get a positive value. With no change in velocity, acceleration should be zero.

It seems this is amount of velocity on tick, not acceleration? My math isn’t great, I probably just need to subtract a value?

Any help appreciated!

For acceleration you need to store last ticks velocity and compare.

Velocity -> Vector Length = Speed
Current Speed > LastTickSpeed = Accelerating, CurrentSpeed - LastTickSpeed = Gain
Current Speed < LastTickSpeed = Decelerating, LastTickSpeed - CurrentSpeed = Loss
