Is there a way to select multiple object and move them all at once?

- just use your mouse to drag a frame around the objects in any 2D-view and press enter.
- You can also hold Ctrl pressed and select them one by one.
- and you can select same type of objects via the VisGroups (list on the right side - 'mark' button)

Also is it possible to have a bunch of set items falling from the sky? something like this http://www.youtube.com/watch?v=vayPBDtB ... re=related its around 7 min

- create new entity: 'prop_dynamic', select any modell and play around with the settings

How do I make one of those wall holding arm things come out and hold a wall section at an angle? I want to make a series of portal jumps.

- search for model name 'piston' and 'squarebeam_off_2x2' and create an brush 128x128

Finally how do I make so only certain surface can be used by the portal gun?

- take black wall/floor textures
- if you want to prevent white walls from portaling use a brush with trigger texture and 'func_noportal_volume' with the size of the area you wont get portals on

- create a prop_physics, prop_physics_override, prop_physics_ornament, or func_physbox, but remember on flags tab, select disable motion, then make a trigger to enablemotion

Go into the "INSTANCES" folder in the "SDK_CONTENT" folder and go into the folder "GAMEPLAY" and find angled, then open it and copy it into your map, or make a func_instance and use the map there.

Options
-make a func_portal_volume with a trigger texture
-make a trigger_portal_cleanser with a trigger texture and go into flags and untick physics objects and clients
-make a thin brush with an clip, playerclip, nodraw, or an invisible texture and put it in front of the wall (make sure it's 1 unit thick)

After selecting multiple objects, you can group them with Ctrl and G. If you want to ungroup them later, I think the key combination is Ctrl and U.

A lot of this stuff can be found on the VDC before you search.

You might do a lot worse than look at these tutorials, they certainly helped me get to grips with things : http://www.youtube.com/user/SolarChronus
