bhoping in valve games

[Nefarious Meatloaf]

Does bhoping work on any other engines besides source? Also curious as to WHY it works in the first place. Not asking how to do it, I can do it somewhat, but why in the world it works in the first place? Anyone know the technical nitty gritty?

It works on Quake games as well.
Unreal Tournament games might have this feature as well.

As for how it works. Well I think each jump adds a bit of speed and when you time it correctly you don't lose any speed at all.
It could easily be solved by changing some values around but Valve have kept in place in their games.

For example, the mod Black Mesa Source made it so that you can't bunnyhop which was a shame.

Say you move 1 meters per second in a straight line. In games, people expect to jump at the same rate or faster rate - you are "leaping" forward, and up, to clear the object. Thus to get to an object 1 meter away within a second, raising in a parabola so you can get on the object, the jump needs to move you slightly more than 1m/s.

If real life, you would run faster, or jump slower, and the physics is determined by what you choose. In games, the speed you run as it dictated by the input you give and the rules of the game (i.e. on a keyboard, if you're pressing W you'll move forward at walking speed). It's "forced" on the object being moved.

So by conforming to what "looks" right, rather than actual physics (in real life, the leap would take more energy, which you'd be able to do but not for as long if you were trying to bunnyhop, and it would be faster but probably not faster than you could run anyway) the game lets you use the rules against it and allows you to move faster by performing a series of unrealistic bunnyhops.

Similarly, you can't really run into a wall and stop instantly without damage. Somewhere you have to simplify the world "rules" to make the game fun, and doing that lets you "cheat" the rules to your advantage too.

BTW: No matter how many medipacks you run over, you can't heal wounds instantly. And if you shoot a person 100 times in the big toe, they aren't going to die.
