偽高速飛行

偽高速飛行（英語：Pseudofly，簡稱偽速飛）是一項錘擊飛行中的進階技巧。偽高速飛行與高速飛行的相同點在於兩名玩家在飛行過程中不會發生碰撞；而不同點在於，偽高速飛行可以在空中更加靈活及精確地移動。

熟練掌握偽高速飛行後，玩家可以用這項技巧來與其他玩家或與自己的分身隨意地向着幾乎任何方向飛行。

通常來說，玩家與自己的分身進行配合會更容易完成偽高速飛行，當然也可以雙人配合完成偽高速飛行，但是需要兩名玩家要有極大的默契程度。

鈎索釋放時機

偽高速飛行與其他錘擊飛行技巧相比，最明顯且重要的區別在於鈎索的釋放時機。

與常規的「兩錘一鈎」不同，在偽高速飛行中，駕駛員必須在每一次錘擊時重新釋放一次鈎索，也就是「一錘一鈎」。

同時，駕駛員也要格外注意鈎索釋放的時長。駕駛員要將鈎索釋放時長把握在駕駛員與動力源之間的距離剛好在錘擊判定範圍之內，而兩者又不發生碰撞的距離。

如果鈎索釋放時長過短，那麼可能導致兩名玩家之間距離過大，動力源的下一次揮錘無法擊中駕駛員；
如果鈎索釋放時長過長，那麼兩名玩家可能會發生碰撞，導致偽高速飛行中斷，被迫切換為常規的錘擊飛行。

因此，駕駛員需要集中注意力在兩名玩家的距離上，以便隨時判斷下次錘擊後需要釋放鈎索時長的長短。

當玩家已經適應並熟練掌握了鈎索釋放時機，那麼接下來就可以嘗試向各個方向進行偽高速飛行，甚至是懸停在半空中。

下降高度

When pseudoflying down, the driver must hook for shorter time lengths as well as more sparingly. Flying down is basically like falling - except occasionally, the driver hooks and the hammer tee hammers.

When leveling out again, simply increase the rate of hooking and hammering.

Transitioning into speedfly

To transition into speedfly, the driver must be especially careful about the hook timing. When you feel yourself starting to go up, the driver must hook for a little bit longer as speed increases. Once you go fast enough, the driver must hook for every two hammer hits instead of one, like a normal speedfly.

An alternative method to transition to speedfly is to have both tees hammer each other at the same time, and the driver to quickly move left or right, and then level out again. This is much faster method, although the same principles as above still apply.

Use cases

A common use case for pseudofly is to fly through tight horizontal corridors that would be unpractical, or impossible, for any other kind of fly.

Pseudofly is also a common technique used in speedrunning.

Starting a pseudofly

When pseudoflying with a dummy, it's important to control the rate at which the dummy hammers. Therefore, auto-hammer is not enough. You can bind a key to have your dummy hammer at will using the following command in the console (F1):

bind x "+toggle cl_dummy_hammer 1 0"

Once you have that set, you can start pseudoflying.

It is possible to start pseudofly in the air, but it is easiest on flat ground. Start by standing next to the tee, then have the dummy hammer you at a fast rate, hook him at the same time, and start moving in the opposite direction in which you are positioned from the dummy.

When pseudoflying with another player, it's important to communicate with them when it should begin. As the driver, you can do so by hammering, switching to the pistol, and shooting at a fast rate.
