Magento new basic shipping method not showing in frontend - magento

Question

I am trying to create a new shipping method. This method allows users to COLLECT items from a paticular warehouse. So not much involved really.
I have followed a couple of tuts online, and have my module built and installed. It is working on the backend, i can enAble it, and set various values.
When i use the frontend checkout....or even use the following code:
Mage::getSingleton('shipping/config')->getAllCarriers();
I do not get the new shipping method name output.
The message i get on the frontend checkout is:
Sorry, no quotes are available for this order at this time.
Even though i have other shipping methods enabled.
I have another extension in use (regarding stock located in several warehouses). As part of this extension, it lists available shipping options...so that i can assign specific options to a specific warehouse. My new shipping method is not listed that shipping options list.
I seem to have everything required. My other extension is not picking up the method...so must be missing something.
Also, given i am getting no shipping options on frontend...confusing.

Answer 1

I was creating a complex shipping method...rather than a copy of the free shipping method. Turns out i actually needed a copy of the free shipping method, so made my life easier...
This was easier than i thought it would be.
Dont want to post all my code (you will also need a config.xml and system.xml file) but heres my carrier model logic file:
class Myco_Clickcollectshipping_Model_Carrier_Mymethod extends Mage_Shipping_Model_Carrier_Abstract {
protected $_code = 'mymethod ';
public function collectRates(Mage_Shipping_Model_Rate_Request $request)
{
if (!$this->getConfigFlag('active')) {
return false;
}
$freeBoxes = 0;
if ($request->getAllItems()) {
foreach ($request->getAllItems() as $item) {
if ($item->getFreeShipping() && !$item->getProduct()->isVirtual()) {
$freeBoxes+=$item->getQty();
}
}
}
$this->setFreeBoxes($freeBoxes);
$result = Mage::getModel('shipping/rate_result');
if ($this->getConfigData('type') == 'O') { // per order
$shippingPrice = $this->getConfigData('price');
} elseif ($this->getConfigData('type') == 'I') { // per item
$shippingPrice = ($request->getPackageQty() * $this->getConfigData('price')) - ($this->getFreeBoxes() * $this->getConfigData('price'));
} else {
$shippingPrice = false;
}
$shippingPrice = $this->getFinalPriceWithHandlingFee($shippingPrice);
if ($shippingPrice !== false) {
$method = Mage::getModel('shipping/rate_result_method');
$method->setCarrier('mymethod ');
$method->setCarrierTitle($this->getConfigData('title'));
$method->setMethod('mymethod ');
$method->setMethodTitle($this->getConfigData('name'));
if ($request->getFreeShipping() === true || $request->getPackageQty() == $this->getFreeBoxes()) {
$shippingPrice = '0.00';
}
$method->setPrice($shippingPrice);
$method->setCost($shippingPrice);
$result->append($method);
}
return $result;
}
public function getAllowedMethods()
{
return array('mymethod ' => $this->getConfigData('name'));
}
}
