Help With A research project using UDK(FOR PSYCHOLOGY)

well i was looking and i think that something must be missing, because when the car barely touch the wall or bump it, the car emites a bump sound, so must be some kind of script that fires up when it touch this wall.
so i think that the next step is to check if that script or line of code exists and how it work.

**paco** · 06-14-2012, 06:32 PM

I also have a lot of problems figuring out which of the myriad of functions gets called when there is a collision. I usually end up putting a log in about 10 different functions (touch, encroach, bump, raninto, RigidBody...) trying to find the right one.

The only thing I can suggest is that because the car gets bumped away from the wall it's possible that is done via the AddImpulse function in the vehicle class - maybe put a log in that and similar functions to see if they get called. More likely however it is done via native code in which case you're kind of stuck....

**tegleg** · 06-14-2012, 06:39 PM

it could be the suspensionheavyshift sound, ive had problems with that firing at random, you can remove the function that plays it, cant remember what off hand.
to get when it hits something do like paco suggested and log touch, bump, RigidBodycollision ect..

**DonFrag** · 06-14-2012, 09:21 PM

simulated event SuspensionHeavyShift (float Delta)

thats the event that works better o more times, still there is some bumps not detected, but this function is more sensible than others

Now i have a new question. The professor in charge asked me to increase the speed..
so i tried this(using tutorials and post in this forum)
first i tried to change de torquevcurve, and the basespeed and max speed to a higher value.

PHP Code:


class CarPLayer extends UTVehicle_Scorpion_Content;

var config vector PlayerLocation;

var float  CurTime;

var float CurSpeed;

struct SCollisionsList

{

    var int RandNumber;

    var float position;

    var float curTime;

    var int nHits;



};

var int lap;

so i compile i can't see any effect on speed. watching the hud indicator of speed, it always tops to 1100 so i cant find a real way of increasing this value.
what im doing wrong?

**U F O** · 07-08-2012, 10:39 AM

Just a guess from a noob but ... you could try GroundSpeed worked for my pawn , but i dont know its effects on vehicles.

**DonFrag** · 07-08-2012, 12:30 PM

but i already changed GroundSpeed
