Hi there, we all know the jumps where we must do 90° turn in the air to land to the block we want... for example jumps like.. at de_inferno bomb (B) Box -> Box or cs_italy @CT spawn Box -> Window... so my question is how to measure this kind of jumps where we must change our movement angle while strafing ? Here is a picture for those who don't understand about what I'm talking about http://img19.imageshack.us/img19/9468/90degreejumpsgq4.jpg

and does the player's model have any effect at increasing the distance cuz of his 32x32 units collision box size?

perhaps you need this info for the aztec jump? :D or maby just in generel..

OT: i can't help you sorry :P

hmm thats a good question, but the answer might not be that interesting if u take into account that u would have to go side by side (with the player to wall ratio) in order to do a certain length. Similar to a perfect edging when doing a longjump on a block (i.e. 250 block with 250.0XX stats) but along side a wall which is X-times more harder than that

the collision model bug cannot be used, it happens when the jumpoff-brush and landing-brush (idk whether these are the right words a mapper would use) have a special position in the map.

measuring these jumps should be a bit hard but i could post a small pic later to make you understand how it should be done although i cannot create a formula for that thing.... ok maybe i could but i dont want to :P

This is a very good question :o
I ask the same to myself for a lot of jump :o

you need to measure both orange lines and add them. sounds simple, eh? the tricky thing is that you need to check that the player is not tocuhing the wall (the blue thing in this pic). this is the shortest distance the player can jump but in fact its longer cuz of the turn.

great question. I think I could explain this verbally, but not through text :x.

Well, I'm not sure if I understood the problem perfectly, but in my opinion there's no way to define how long is that jump in units. There's just no point of doing it anyway. As you said, the distance can be calculated, but the turn just ruins it. The calculation would only make sense in situations where the 1st or the 2nd block would be parallel to the 90 degree turn, you would just need to add ~32 units to the distance between the blocks. In my opinion longjumps should be ONLY straight jumps, with nothing between the blocks.

EDIT: Well, if you use a program like SilverNinja's LJ difficulty calculator, you could calculate the DIFFICULTY of the jump, but not the distance.

I'm not talking about the stupid normal longjumps right now.. u can find everytype of trickjump at everymap and there are MANY trickjumps where u should do some turn like this while u're doing airstrafing.
For example ppl will know can they do some trickjumps like these I gave for example (comparing their LJ rec and the difficultly of the jump) or is it poss the uber sc on kz_man_dreaming or what distance to add when u have to do some turn at the end of the trickjump.

P.S. maybe the strafestyle is a factor too? (smaller strafes => less space => closer to the wall => shorter distance)

U just need to add +32 units per 90 degrees turn..

32 units ? :|

kinda obvious... player's center should be at least 16 units away from a wall (plus 0.3xx or w/e it was that hl engine added to prevent colisions). since there are 2 wall faces we should add 16 units twice to the distance. there are others methods for calculating this w/o using player's center, and if its still not obvious you can figure it out by yourself coz the tip was already given.

also there should be some space for strafes and ofc 90 turn cant be done instantly

so how far is the jump at inferno bombspot b?

Since when people have calculated units for jumps which are not longjumps? If you want to calculate some jump's length in units, aren't you comparing it to a longjump? Also as you said, it depends on the players own strafe style etc. There's just no point to compare it to a longjump.

So u are saying that its sensless to calculate this kind of jumps or impossible ? I was just interested about that and thats why I made a thread about it -_-

mdq16/02/2009 09:42

m... if what you want is for scripting y cant help you but i can tell you it's based on skills ^^

flibo, now you see some things sensless, but when you didnt know about kz and someone ask you what was an "strafe" you also said: Why you need an strafe its sensless useless and you dont need it??? or just try it, you like it, and start playing it to become what you are now??

In my opinion, it's impossible to calculate it, but POSSIBLE to ESTIMATE it. But I don't know if it would be very accurate. A program like SilverNinja's LJ difficulty calculator could be used, with some optional additional variables. E. g. it could ask for your strafestats of your lj record, and use those results to estimate it more accurately. Oh well, I'm not so sure at all.

So that's your first post after 2 years and 5 months? :D
