1) bind mwheeldown +jump
Add this to the console, it will bind your mousewheel scroll down to jump. This allows bhopping to be far more easier than timing the jumps with the space bar.

2) Watch and study the L2BHOP video on youtube.
L2BHOP - Counter-Strike Source Bunnyhop Tutorial

3) Change your mouse sensitivity to a high value. Not something stupid, just enough to make bhopping easier. I use 15 as my sensitivity value.

Useful commands
cl_showpos 1 (Shows your positon/ angle blablabla...)
net_graph 3 (Shows server tick-rate, fps, latency e.x.)

Things you should already know
1) You run faster with a scout.
2) Practice makes perfect. Bhopping will not come easily, it took me a good few hours to get the actual basics, and then even longer to master. (I still practise even now)
3) The scout does not necessarily improve your bhop speed/ performance.
4) Crouching whilst you BHOP improves your speed.
5) The better you time your jumps the more speed you will achieve, also, the perfect angle/ position increases your BHOP speed.

dude thanks for learning me , still trying on that map we was on for like 1 hour, that 1 with the three difrent steps to jump on thanks <33 peeace ^^

Saved my life with this tutorial, and thanks heart and dyna for teaching me how to do it in game ^^. Already very supportive which is fab!

tanks it is much more easy now

hey i never knew that. i just beat advi harder with this

It helped me on BHOP
Tho, i cant bhop very good... Practise is the key to make it even better

yup its good tutorial alright, i saw the video on youtube its awesome!!!!!

i use
bind mwheeldown +jump
bind mwheelup +jump

its Much more Easy.

but good tutorial

heatrless,I can bhop good but 5-8 jumps no longer...how to jump more,oh and how to gain more speed
--------------------------------------------------------------------------------------------------------
sorry for my english..lol

If you can only jump 5-8 times maybe your timing isn't very good?
Or maybe because your sensitivity is to low.

To gain more speed hold down crouch, and perfect your jump timing.

ok I now what is the problem..my sensitivity was low!

Ye, put the sensivity ingame bout 13-15

umm i improved greatly in bhop but the problem is i can't do bhop on the ground only from platform 2 platform AND i keep overjumping

Edit: Now i'm able to bhop on solid ground and platform to platform
But when i try 2 speed up and go on a platform in a bhop map i suddenly stop

If your stopping it means you need to improve your timing.

Practise bhopping whilst holding down the crouch button. You will see a huge difference in speed.

Also, you should know that if you are using crouch whilst bhopping. You must stop using crouch when doing a uturn, otherwise you will loose a LOT of your speed when turning.

I think my timing is bad too... The strafe is good, timing is the problem
