Shared Folders Linux

Select the virtual machine, click on Settings, the above window will open. Click on the plus icon to select the folder you want to share with the virtual machine. Here I share the c:\Users\...\Desktop\HostDesk (the folder names are case sensitive) on the Windows 7 to share with the virtual Ubuntu. The shared folder name is Desktop, which will be used by Ubuntu to mount it.

Once you created the share, is time to start your virtual computer in order to mount it. Create a second folder on Linux's Desktop. Now, you should have created one folder on Windows 7 desktop, and another one, on Linu's Desktop. These are the folder you'll mount together.

Open a terminal and, inside the terminal window, use the search box if necessary.   

use the following command line, replacing "HostDesk" and "LinxDesk" with the share names you defined:

Variables on Scratch

Variables are used whenever a value must be stored — i.e., if a project required the user to input a name and then remember that name, the name would be stored in a variable. With this, the name can be retrieved at any time; all the project has to do is check the value (which is the name).

The look of the variable can be changed in to three forms: The normal readout, the large readout, and the slider. The form of the variable can be changed by double-clicking or right-clicking it and selecting the option that is wanted, or clicking it using the grow/shrink sprite tool.

The following example illustrates one use of  one variable. The variable name is "Flying".

The following scripts control the value of the variable "Flying", the vertical movement of the helicopter and the land/crash speed. Two different forces are "simulated" in this really simple project: the propellers thrust (adding a positive value to "Flying") and the gravity force (constantly changing "Flying" by a negative value).

The actual movement of the helicopter is controlled by the "Change y by" block, where the standard value is replaced by the value of the variable.
