Adding velocity to a vehicle in the direction it's facing

[Farad]

I'm making a simple boost for vehicles. How can I add 25 velocity to a vehicle in its forward direction?

Use vectorAdd(%vec1, %vec2) and vectorScale(%vec, %scale) with %vehicle.getVelocity(), %vehicle.getForwardVector(), and %vehicle.setVelocity(%vec).

is there any disadvantage to just using addVelocity rather than setVelocity(vectorAdd(getVelocity, ...))

i would think the former would be much more efficient character-wise and performance-wise but maybe i'm wrong?

anyway the idea is to use getForwardVector, and then scale that to w/e speed you want the boost to be at (eg 25) to get the velocity added, and then add that velocity

Character-wise yes but any difference in performance would be negligibly in favor of setvelocity. Addvelocity is a shortcut intended for use with the events system and is implemented in torque.

Thanks. Is this correct?  %vehicle.setVelocity(vectorAdd(%vehicle.getVelocity(),vectorScale(%vehicle.getForwardVector(),25)));

Yes, it is.
