[vJASS] Jump

Syntax error because the globals block needs to be at the top.

Dang. Thanks :)

And I tested this without the +es added, and it works fine.

Whoa....?? Waaaaaaaks!! What do you have to say for yourself? :P


*Fixed

what do u mean by +es?
ill try it again someday, because im not working on my RotG Reborn map for now, because i created another map

BTW, i used spongebob as the model for the previous tests, does the model affect the jump?
and yeah also, i set the duration as 1 sec and the arc to 0.85 to make it higher

what do u mean by +es?

Without the changes it supposedly needed.

and yeah also, i set the duration as 1 sec and the arc to 0.85 to make it higher

The arc might cause it, I only tested with 1.8 (The recommended arc). However, I don't see why it would.

Bah nobody uses Bezier anymore, when they are a lot better than other formulas.

This can be simplified to a basic interpolation formula:

function LinearInterp takes real a, real b, real t returns real
     return a + (b-a)*t
endfunction
function BezierInterp takes real a, real b, real c, real t returns real
     return a + 2*(b-a)*t + (c -2*b + a)*t*t
endfunction

In this 3 points bezier curve a, b, c represent points respectively and t represents the step, 0 >= t <= 1.

now lets say we are going to make a perfect parabol.
in a jump, we would try to make a perfect parabol without much problems. The first condition we set for the X & Y axis is that, a is the start point, b is the mid point between c and a; and c is the end point. Thus X & Y axis will be interpolated linearly, and we will eliminate b, since it's the midpoint.

for Z axi (heigth) we'll use the bezier interpolation, if we take into account that heigth is an absolute value, then a = c, no matter in which terrain type the unit starts and ends, in ground of heigth is 0.0. Thus:

function ParabolicInterp takes real a, real b, real t returns real
     return a + 2*(b-a)*t + 2*(a-b)*t*t //we multiply last by -1 and we change inside symbols
endfunction
//thus it simplifies to
function ParabolicInterp takes real a, real b, real t returns real
     return a + 2*(b-a)*(1.0-t)*t
endfunction

but if we are interpolating over and over then 2*(b-a) would turn into a constant value so it ends up being.

function ParabolicInterp takes real a, real m, real t returns real
     return a + m*(1.0-t)*t //where m is 2*(b-a)
endfunction

Can you help me? I want to make a jump function with GUI, please tell me what to write in custom script functions! I can't READ jass :(

u need to go to "Custom Script" action and type

call Jump(udg_caster, 1, GetLocationX(udg_point), GetLocationY(udg_point), 1.8, 300, udg_sfx, udg_sfx2)

heres the function, use it for reference

function Jump takes unit whichUnit, real dur, real destX, real destY, real curve, real radius, string sfx1, string sfx2 returns nothing

Thank you, now i'll see fi that works!

It Does Not Works! Like the knockback function!!!

Add support for running a specified function when jump is complete?

Ex: Tauren jump slam thingy
-Jumps the Tauren to a target area, smashing all the n00bs to make them fly backwards from him when he lands.



Its also nice to have a pause option and options for playing a units animation. Maybe JumpEx?

Ex: Priestess Tiger hop
-Makes the tiger jump 600 distance towards its angle (plays walk animation while jumping and short time)



You could make it run the function on land by adding a taken string to JumpEx, and then ExecuteFunc( takenstring )ing it when the person lands.

EDIT: After testing, I noticed that you forgot to IssueImmediateOrder( .u, "stop" ) after unpausing them in the ondestroy method
And there isn't random sliding at the end/start >.>
Also, make it so you cant jump 0 distance, to "Protect users from themselves" as Dusk would put it

The jump has a bug : your unit can be removed from the game by jumping in the black zone, out of the map...

Really? I thought I fixed that.... too bad, gonna check it out later.

Sure, thanks for advice.

Hey, Not sure if im the only one getting this problem. However after it does the jump sequence it just keeps sliding and never unpauses. Heres what I have for the code.

Nvm got it working. However I found a bug, if you jump into ground lower then you it has u floating higher.

What's the variable settings? I'm not that good at jass, I've tried looking at it, and I cant seem to find a place, where you state, if I have to create something in my map, besides a Dummy unit.
What do I need to do to make this work in my map?
Also, I tried copy pasting, this into JC, and made a syntax check, got a whole bunch of errors. Can anyone explain?

Thanks Really Good Idea 4/5
