(i did see the demojump thread, but it was just some random questions and discussions. and after excessively jumping around as a demo i thought i might just give it a shot. me wanna post a guide too!
Greetings, Lads.
Welcome to my little edutaining course about the joys and pains of Stickyjumping. This covers all the basics, some advanced techniques and of course som great examples of what you can archieve by Stickyjumping. But lets not rush this all over, right? Let's that with the general idea:
1. Stickyjumping and you...
1.1 What is Stickyjumping?
You already might have heard of rocket jumping, a rather ancient, yet effective, technique using self-injuring ground attacks to create a momentum propelling you anywhere you desire (mostly upwards). The Demoman can perform an equal... well... a superior technique: Stickyjumping. You use your stickybombs to launch yourself up in the sky and with a little training you can land whereever you want.
1.2 The Stickylauncher
The device you want to use for that is the stickylauncher. Don't bother with the standard issue grenade launcher. It is not that good for jumping. You will find the stickylauncher on weapon slot 2. The launcher has an adjustable firing mode. When you tap the primary fire button (mouse1) you will launch a sticky. It will fly in an arc and stick to most things on impact. It however repels from doors, sentries, players and other moving world objects. The secondary fire button you can detonate any sticky that you shot so far. Holding down the primary fire button will charge your gun. On release or maximum charge it will launch a sticky further than usual. you can shoot them pretty far that way. You can deploy eight stickies at a time. as soon as you try to add a nineth one the first one you placed will detonate, the tenth will detonate the second and so on. so be careful when replacing them, those detonating single stickies will hurt you.
1.3 Your very first stickyjump
Unless you don't know how to do it in general here is a brief introduction of what you have to do:
1. Place a stickybomb on the ground
2. Get on top of the stickybomb
3. jump a little bit upwards, just a tiny tad
4. detonate
Easy, eh? Now watch yourself flying. You will go upwards quite fast, and after you landed you should be moderately hurt (depending on map).
1.4 Various Jumps
Depending on your position you can perform a variety of different jumps. The most common are the hi-jump and the forward-jump. The basic idea is as follows: take your sticky and your physical center. then draw an imaginary line through that... this will be the initial propelling direction of you. Gravity will of course pull you back down after some flying, so you have to calculate carefully. If you directly stand on the bomb and jump, then you will go up all the way. if you move a bit forwards, then the angle drops a bit. and if you are already a step away from it, it will propel you forward quite fast.
In mid air you can control your flight too. holding the strafe right button and turning clockwise (right) will make you change your direction to right (at least in older hl games). pressing backwards will make you stop flying forward (wtf). This is excellent for pinpoint landings.
1.5 One or two bombs?
This is a difficult question. Whilst one bomb gives you access to most areas, two bombs will get you even further and faster to your destination, even if that means you will take a lot of damage. If you might encounter enemies at your LZ, you should only use 1, if you can reach your destination with one bomb in the first place. If the area is somewhat clear or you need to go really far, use two.
1.6 The downsides of Stickyjumping
1.6.1 Health
Demomen have a standard maximum health of 175 points. thats quite average and stickyjumping will strip you a fair amount of that.
