Im making kind of endless racing game, and a problem is - I need to spawn vehicles with certain speed, so it dont ruin highway movement. There are ForwardSpeed variable in FVehicleState struct in ChaosVehicleMovementComponent, but it seems that i cant acces and change it through child class.  
Is there a way to manipulate this value or another way to set velocity/speed at begin play?

Hello! I don’t know if I understood what do you want.

If you want a vehicle with a specific velocity you will have to adjust multiple values.

Torque and RPM is your engine capacity. Gear Ratio can be used to reach high speed faster.  
Use copilot for more details on this values.

Good luck.
