So i’ve seen that the only way to get diferent trace results with surfaces it’s physical materials has anyone got any experience with them, tracing down the landscape and getting diferent result ?

#2 



function scanlandscape()
{
	local vector loc, norm, end;
	local TraceHitInfo hitInfo;
	local Actor traceHit;
	local PlayerController PC;
	local UTPhysicalMaterialProperty PhysicalProperty;

    PC = PlayerController(Seats[0].SeatPawn.Controller);

	end = Location;
	end.z = Location.z -100;
	traceHit = trace(loc, norm, end, Location, true,, hitInfo);
	///DrawDebugSphere(end,56,6,0,255,0,true);

	PC.ClientMessage("");

	//fuelmultiply =(carspeed * 0.001);

        fuel = (fuel -(carrevs * 0.00001)  ) * fuelmultiply;

	if (traceHit == none)
	{
		PC.ClientMessage("Nothing found, try again.");
		return;
	}

    PhysicalProperty = UTPhysicalMaterialProperty(HitInfo.PhysMaterial.GetPhysicalMaterialProperty(class'UTPhysicalMaterialProperty'));



     //check the material type and change wheel particles
 	if (PhysicalProperty.MaterialType == 'Stone')                 ///track
	{

        bisinthesand=false;
        bisongrass=false;
        bisontrack=true;
        
        UDKVehicleWheel(Wheels[2]).SteerFactor = 1.0;  ///front wheel
        UDKVehicleWheel(Wheels[3]).SteerFactor = 1.0;  ///front wheel
        UDKVehicleWheel(Wheels[0]).LatSlipFactor = 2.75;
        UDKVehicleWheel(Wheels[1]).LatSlipFactor = 2.75;
        UDKVehicleWheel(Wheels[2]).LatSlipFactor = 0.75;
        UDKVehicleWheel(Wheels[3]).LatSlipFactor = 0.75;

       }
       
}

original code from tegleg.

I have problema the code does not detect the landscape any idea on that ?

#4

Oh my bad, i traced, like upside down i think is said, trace end and trace start in wrong params. LoL. Now it Works now ima try the phyisical material.

#5

Awsome it Works! ! ! Bye bye collision cylinders and volumes everywhere in the map. Thanks gaz!!

#6

Problem, how do you assign physichal material property in the editor ??

#7

Oh nvm i had to create a class physichal Material in the code.

#8

no worries.open the landscape tool,in the target layer section hit edit.next to the texture thumbnail is where you enter the physmat.

#9

Yep i got that.

#10

Awsome i discovered that they work to on foliage actors. :slight_smile:

#11

pretty sure it works on any actor.
