UDK - Can't change vehicle speed

and313

Hey guys,

I'm realy new to this UDK stuff but i wan't to learn but I maganed to get to a dead end rather quickly. I followed this tutorial here (http://forums.epicgames.com/threads/850845-Inside-the-Scorpion-Scripting-your-own-vehicles) and everything wen't well I can see MyCar under actor classes and drive it around. Now to the problem...

I can't change the maxspeed of it. Different torque settings and maxspeed set to 8500 like sugested on the tutorial site does not help. After I make the changes to the UTVehicle_MyCar.uc file I just save it run UDK and it says that it has to do something to the script, then I press yes and a DOS window pops up. It says that everything is ok but afterwards there have not been made any changes to the speed of the car when i drive it around.

Help would be appreciated...

tnx

hmm, well your groundspeed is still at 5000, max speed is at 6000. Also notice that your torque curve has zero output at its highest setting, which is at 4000. IE when your virtual engine is at or over 4000 rpm there is no more useful power.
You'll really need to look into both the engine and torque curves if you want a higher top speed.
Your max torque (aka wheel power) is between 0 and 2000 RPM. It drops off sharply as you get faster. You're in effect, limiting how fast you go.

i changed everything in torque to 50000 also in engine rpm. maxspeed, groundspeed, airspeed also set to 50000 but still no changes. i also set maxtorque value to 50000.

Below is the code you will find for one of our vehicle speeds, it's a prototype, I just saw your question and wasn't sure if you were still having problems. Just changing values isn't going to work. I will return another time to explain as I have much work to do. Good Luck!
