Time Travel 1

Change your perspective as you use the portal gun to travel through time instead of space...

(Cubes cannot travel through time due to paradoxical restrictions)

Update: Cubes less glitchy, fixed problem with prop_statics in the first room

Since everyone seems to be enjoying this concept, I have begun working on a second map with more advanced testing objects: lasers

This is an amazing game, and I hope you do more like these (like you did with Time Travel 2, the one I'll play next). I would love this mechanic for a Portal 3, in fact.

Absolutely excellent. Could you possibly message me and tell me how you pulled off the mirrored cube effect, and how you hanlded setting the orange portal automatically when the blue one is placed by the player? I've done a lot of source maps, and this is pretty unique.

Ha! Never mind. I finally figured it out. The secret is that moving the cube in the future (old looking) does not move the cube in the past. Get both cubes in the room with the rising platforms. Drop the future cube in the goo to cause it to regenerate in the adjacent room. Move to the past, through the adjacent room, then to the future again to recover the respawned cube. Put it on the receptical to open the exit door. Hit the button to raise the platforms. Quickly move to the past, through to the adjacent room, back to the future and cross the plaforms to the exit. I know that was as clear as mud, but hopefully it will help. GREAT MAP!

I'm stuck right where 42:nd Guy was stuck. Any hints?

Never mind. I finished it.

I don't get how to beat the level where you're supposed to put the present and past cubes in two different places. I can't get into the room where the present is (where I'm supposed to activate the plattforms rising from the toxic waste) but still be in the past, to jump over them. The previous links given here doesn't work. Could someone please explain?
It's a great map, but I'd like to finish it.

I cannot figure out the one with the two blocks and the bridge. I can't find any youtube videos showing what to do. Any help would be appreciated.

How did you get it to go in the other time zone by using the portal gun is it a mod or something

I have made 2 time travel concept maps but they are more of a demo thing where as this map is fully functional and AWESOME here is a link to my first TTC map http://steamcommunity.com/sharedfiles/filedetails/?id=146820630
