Plz give me portal 2 mapping ideas!!!
You need to make your solution not obvious to the player. Also, experienced players normally will see your moves naturally very quickly, so you should go with a creative move or chain of them... And once you have it well defined, you need to hide it... how? usually by making the player use each of that chain's components in an usual way. Making the player think he knows the purpose for each element and he is done with it (when he's not). If there's a funnel envolved in your final chain or maneuver, you need to give that funnel another function apart from the final chain, like to move a cube from position or make the player reach a certain place, ok?
My personal advice is: PLAY Portal2 
Play a lot, and if possible, play to all hardest maps you find. This way, you can usually get good ideas. I think many good moves or chains pop up while you are playing and trying to figure out a solution!
You should also read Markiu's explanation about hard maps creation in response to a guy's question posted in his map Heaven's Gate thread. Here.
oooohhhrrr Thanks! ^-^
Thanks u guys I have gotten many ideas playing hard tests and Wibi Data (which is a portal 2 mod doohickey which I recommend u play). By testing these maps it gave me ideas of how to make test harder to solve but not too frustrating and have some ideas for new testing elements (which Ill post in the downloads page when I finish making them [if I can manage making them in the first place] {;D). Well I wanna thank u guys again for ur help in helping me realize that I shouldn't use creativity from others but use the creativity from my heart I wish I could say more than just thank you. If I have any trouble ill let u guys know on the forum. Hope I wasn't any trouble XD Cya!
I will give you an idea
