Throwing Pilot based on Vehicle Impact Vector

Greets All...

Some of my vehicles can 'ollie' and do tricks while airborne. I'm now trying to throw the rider if his impact angle is too steep. I've modded the impact function but I can't figure out which values to use as the threshold. I thought making the y z angles greater than 45 would work but it doesn't. Can someone explain this for me?

Here's my function:

function JetBikeData::onImpact(%data, %obj, %col, %vec, %vecLen)
{
   //error("VehicleData::onImpact(" SPC %data.getName() @", "@ %obj.getClassName() @", "@ %col @", "@ %vec @", "@ %vecLen SPC ")");

   if ( %vecLen > %data.minImpactSpeed )
      %obj.damage( 0, VectorAdd(%obj.getPosition(), %vec), %vecLen * %data.speedDamageScale, "Impact" );

   // associated "crash" sounds
   if(%vecLen > %data.hardImpactSpeed)
      %obj.playAudio(0, %data.hardImpactSound);
   else if(%vecLen > %data.softImpactSpeed)
      %obj.playAudio(0, %data.softImpactSound);
   
    %x = getWord(%vec, 0);  
    %y = getWord(%vec, 1);  
    %z = getWord(%vec, 2);  
    echo ("*************************************** Vehicle Vector is " @ %vec); 
 
    if (%y < 45 || %y < -45 || %z <45 || %z < -45) //<-Gibby:what should these be?

	echo ("******* Bought The Farm - Throw Player and Damage Him Here");
	return;   
}



Thanks

Doh! Solved this myself. FYI in my first post I used the vector, but the correct function is getTransform. The 4-6 digits of that function have the rotation in radians, so interpolating (Pi/2 = 90 degrees) we get something like this:

function JetBikeData::onImpact(%data, %obj, %col, %vec, %vecLen)
{
   //error("VehicleData::onImpact(" SPC %data.getName() @", "@ %obj.getClassName() @", "@ %col @", "@ %vec @", "@ %vecLen SPC ")");

   if ( %vecLen > %data.minImpactSpeed )
      %obj.damage( 0, VectorAdd(%obj.getPosition(), %vec), %vecLen * %data.speedDamageScale, "Impact" );

   // associated "crash" sounds
   if(%vecLen > %data.hardImpactSpeed)
      %obj.playAudio(0, %data.hardImpactSound);
   else if(%vecLen > %data.softImpactSpeed)
      %obj.playAudio(0, %data.softImpactSound);
   

      %trans = %obj.getTransform();  
      %tx = getword(%trans, 0); // first, get the current transform values  
      %ty = getword(%trans, 1);  
      %tz = getword(%trans, 2);  
      %rx = getword(%trans, 3);  
      %ry = getword(%trans, 4);  
      %rz = getword(%trans, 5);  
        
        
    echo ("*************************************** Vehicle Transform is " @ %trans); 
 
    if (%ry < 1.2 || %ry > -1.2 || %rz < 1.2 || %rz > -1.2)

	echo ("******* Bought The Farm - Throw Player and Damage Him Here");
	return;   
}
