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

also where are the jump plates located in the editor and how do I use them?

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.

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

• 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)

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

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

• 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

and look here, please: Portal 2 Mapping Wiki

hope that helps, best regards

• 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.

I guess I could've looked up vdc but I didnt know about VDC to begin with.
