Error in getting block in a template

Question

I am a magento beginner and need help with creating a new custom block. Basically, I just want the block to show "hello" if it is called.

1. Module installation xml file, app/etc/modules/MyExtensions_HelloBlock.xml

   <?xml version="1.0" encoding="UTF-8"?>
    <config>
       <modules>
         <MyExtensions_HelloBlock>
            <active>true</active>
            <codePool>local</codePool>
        </MyExtensions_HelloBlock>
      </modules>
   </config>
   

2. Module configuration xml file, app/code/local/MyExtensions/HelloBlock/etc/config.xml

   <?xml version="1.0" encoding="UTF-8"?>
     <config>
       <modules>
        <MyExtensions_HelloBlock>
            <version>0.0.1</version>
        </MyExtensions_HelloBlock>
      </modules>
      <global>
        <blocks>
            <helloblock>
                <class>MyExtensions_HelloBlock_Block</class>
            </helloblock>
        </blocks> 
      </global>
   </config>
   

3. Block class, app/code/local/MyExtensions/HelloBlock/Hello.php.

   <?php
   class MyExtensions_HelloBlock_Block_Hello extends  Mage_Core_Block_Template 
   {    
      public function hello()
      {
      echo "hello";
      }
   }
   

4. Template file for the block, app/design/frontend/default/default/template/helloblock/hello.phtml

   <?php
    $this->hello();
   ?>
   

Then I call my new block like this in the template "app/design/frontend/venedor/default/template/page/1column.phtml"

echo $this->getLayout()->createBlock('helloblock/hello')->setTemplate('helloblock/hello.phtml')->toHtml();

Result:

Fatal error: Call to a member function setTemplate() on boolean in /app/design/frontend/venedor/default/template/page/1column.phtml on line 58

I was following this tutorial.

You have added wrong block class, it should be app/code/local/MyExtensions/HelloBlock/Block/Hello.php instead of app/code/local/MyExtensions/HelloBlock/Hello.php

You are missing Block directory in the module
