Jump / Throw Skill Issue

[akrep_ve_su]

Hi,
I am making a skill similar to the Toss skill in Dota; caster picks a random unit in 300 range and launches to the target location. Although it seemed quite easy at the theoretical part, it sucked pretty good when i tried to simulate a natural looking flight animation.

What you see above is what i've tried first time: a lame lineer form of 1 second flight. (It is also a pattern of unit flight waypoints) -btw i sense that i also suck at speaking English -
Anyway, it looked pretty bad when tested so i wanted a make a parabolic flight like in the second graphic. But the thing is i can't figure out a formula (function) for a parabolic flight. I tried some things with integral on paper; but nothing good come out of it
I may simulate a parabol-like flight by manipulating movement rate but i guess there should be an easier way. I mostly like figuring out things on my own but i am really stuck this time I hope someone will help me before my brain just melts down
---LATER EDIT----
I mistakenly deleted my other post; here is the other problem with "lineer toss":
1-) When tossed unit lands, a dummy is created to cast thunder clap (via warstomp effect) to simulate the drop-damage but when dummy casts the spell, no effect can be seen; so i had to trigger a SFX. So how do i fix this mssing animation problem?
2-) Upon landing, tossed unit keeps sliding; this results a graphical glitch with landing effect and tossed unit not standing on the correct position when toss spell is complete. Appearantly i made some calculation mistakes with speed / distance and time but i can't find out where it is. (toss example is included in attachment)

I guess you should try something like
f(x) = Z*x - x² ( where x = time in seconds and Z is constant )
for parabolic flight.

//PitzerMikes JumpParabola
function JumpParabola takes real dist, real maxdist, real curve returns real
    local real t = (dist * 2) / maxdist - 1
    return (- t * t + 1) * (maxdist / curve)
endfunction

Thats it And please not double posts use edit instead

Anyone noticed my 2nd question? Or read the entire post? I really need help with the GUI Toss issue if anyone can =)

The unit should be sliding, when there is no real comparison, to check if the unit's height is higher than 0. Make a check, so that you assimilate the height value in the code.
(GetUnitFlyHeight(u) != 0)

 

[akrep_ve_su]

Set a Real variable for "tossed unit height"
If variable value is 0, then stop "movement trigger" to prevent sliding.
Is this what you exactly suggest? =)

 

[Pharaoh_]

Yep, that's it. You don't need a variable (well, it depends on the method you are going to code this though), just get the unit's height; if it gets 0, then prevent sliding.

 

[akrep_ve_su]

Ohh, okay. Thank you for the idea, this should fix up sliding i guess =) I will try as soon as i reinstall war3 =)

 

[akrep_ve_su]

Actually it didn't fix the problem; the "tossed" unit keeps sliding after it lands. =)
