Left strafe key should only be pressed while moving the mouse left. Right strafe should only be pressed while moving the mouse right. The opposite will start moving you backwards. Help it's not working: Move through the video in order. Can you gain speed by moving in zig-zags? Can you jump in a circle, gaining speed slowly? Can you air-strafe to the bottom ledge? Help it's still not working: Never press the forward key. It's tempting to press the "+forward" (W) key when wanting to quickly move forward. If anything, you should only have to press it for a fraction of a second when you first start moving (for a circle jump). after that, do not press +forward. Why am I losing momentum? Could be that you're not using the mouse wheel to jump. Timing the jump with the space bar is impossible for basically everyone, especially beginners. Also note that 300 units is portals "speed limit" for allowing air strafes. If you exceed 300 units of velocity, you will lose the ability to air strafe. This makes it much harder to gain speed, and removes the ability to maneuver in the air. Use the technique in the video to maintain this +300 unit speed. Did they patch it out? No, and extremely unlikely to ever happen in the future. Do I need to crouch? No. Although it seems there is a technique for hitting a slightly higher speed by holding crouch on every other hop, but that's beyond the scope of this tutorial. ----- More info on opening a console: https://developer.valvesoftware.com/w...

Since jyjey beat my old time, I decided that I should try my luck at this chamber again. Luckily, this chamber is becoming less about luck the more I play it. The reportal shot is pretty consistent for me now, leaving the elevator escape as the biggest challenge. Since the elevator escape happens pretty fast in this run, I should probably explain exactly what happens. If you just normally press the button in the elevator, there is a clip brush (invisible wall) that appears to prevent you from leaving. It is possible to move towards the exit while pressing the button, and have your body be occupy the same space as the clip brush when it appears. This traps you in the space between the elevator and the free space outside, killing you when the elevator goes up. It is also possible to trap yourself outside of the gap between the elevator and outside, where the elevator can pass by while you are trapped in the invisible wall. This involves almost perfect timing. In either case, the only way you can stop being stuck in the invisible wall is to shoot both portals on any surface. Since the distance between dying and staying alive in the wall is pretty small, it's hard to tell if I'm going to get killed by the elevator or stay safely outside. For this reason, I always shoot the second portal pretty randomly; if I miss, I die and restart unless I had perfect timing on the button. If I did have perfect timing, I can just shoot another so who cares. In both cases it is totally harmless so why not just try and make some crazy shot where I don't aim. tl;dr I don't aim because I don't need to Learderboard: http://steamcommunity.com/stats/Porta... Fun fact, I beat the illegitimate time that formerly held #3 on the leaderbord. Jyjey is actually the current second place.
