This custom class is a trigger that tests the speed of the vehicle against a value set in unrealed by the mapper.

The test against the value set can be greater than or lesser than. Its a boolean variable (true/false) and is set to greater than as a default and can set by the mapper in unrealed.

Once the condition has been me the speedtrap will call whatever is in its event property.

• Can Test For > or < lower than stateted speed set by the mapper.
• Triggers self when condition is met.

Whatever touched us gets validated in the touch function, if we get touched by a vehicle or one of its children the result is a valid ref to a vehicle stored in local variable 'vec'. This then gets passed to the function Test_Speed for processing. and the touch function can go back to checking if something else is toucing us.

The test_speed function converts the valid vehicles velocity into a more managable number through using Vsize?. A typical test for a vehicle stopping within the collisiion hash of the Speed_Trap would be lower than 400.

function test_speed(vehicle thvec)
{
 if (((bLessThan) && (thvec).VSize(velocity)<TestSpeed) || 
    ((!bLessThan) && (thvec).VSize(velocity)>TestSpeed))
    triggerevent(event,self,instigator);
}

So quite simply when a vehicle traving the right speed to meet the condition set by the mapper touches the speed_trap it calls whatever is store in the event property just like a normal tigger.

Completed Script

The completed script looks like this;-

//-----------------------------------------------------------
class Speed_Trap extends Trigger;

var () float                                    TestSpeed;
var () bool                                     bLessThan;

function Touch(actor other)
{
 local Vehicle vec;
 vec=Vehicle(other);

 if ( vec != none )                                     // IF TOUCHED BY A VEHICLE
    {
    if ((bLessThan) && (VSize(vec.velocity)<TestSpeed))  
       Triggerevent(event,self,instigator);             // TRIGGER SELF

    if ( (!bLessThan) && (VSize(vec.velocity)>TestSpeed) )
        Triggerevent(event,self,instigator);           // TRIGGER SELF 
    }
 }
