here is the explanation for ladder jumping, (that i dont understad)
Ladder Jumping
Near the top of a ladder, there is a location where you can tap the jump key and you will gain higher attitude than you would normally from climbing all the way. This spot is near the top of the ladder where you can see over the ladder.
1. Climb up to the very top of the ladder, but stay on the ladder;
2. Find the "sweet spot" that is around where your waist is at the top of the ladder.
3. Tap the jump key.
Ladder jump example
The difficulty in performing this jump is finding the sweet spot. It will take some personal experimentation to be able to do this consistently. In the mean time, you may try looking before you attempt the jump if that helps you to find the sweet spot.
To practice this jump, you can download our example jump tutorial map and try your hand at the example in the screenshot above. It will take experimentation and practice to do this consistently.
now here is the explantion for circle jumping,
Circle Jumping
Circle jumping is the same as strafe jumping, but it can be done from a near standstill (you still need to move forward a bit) in order to get more distance. Follow the same directions as for strafe jumping.
