I got rid of the "This vehicle is locked" message for this RV.
package RVLockPackage
{
function RVVehicle::onCollision(%this, %obj, %col, %pos, %vel)
{
if(%obj.locked && %col.getType() & $TypeMasks::PlayerObjectType)
{
return;
}
parent::onCollision(%this, %obj, %col, %pos, %vel);
}
};
activatepackage(RVLockPackage);
Compare it to the vehicle locking script.
