[patch] implement SPLINEFLAG_TRAJECTORY (jump effect visual)

[Wojta]

Well then...why its dynamic? In knockback effects, its just damage (and feral charge has no basepoints for jump effects)

EDIT: yeah, because theres still same distance in knockback

EDIT2: which means maybe we can use this as template...

EDIT3: or maybe we cant...I just cannot figure it out, something is always missing

[SilverIce]

Seems i have found dependence: for example feral charge parabola have constant max height distance -- 0.49

Z max = ((Duration^2) * vertical_acceleration) / 8, Duration is movement time, in seconds

example:

Duration vertical_acceleration Z max

feral charge:

0.166 145.16 0.4999

0.346 33.41 0.4999

death grip:

0.131 233.09 0.4999

0.315 40.31 0.4999

have fun

P.S. that movement should also relocate player\\creature on server side, there shouldn't be any instant relocations like i saw in first post

"GetMap()->CreatureRelocation((Creature*)this, x, y, z, o)"

[Wojta]

0.4999 is almost 0.5, EffectMiscValueA /10 is also 0.5

But misc value for death grip is 0

[Forgotten]

Maybe 0.499 is hardcoded value.. in this way there is no sense to seek for it in dbc

[faramir118]

Well we have a relation ship between two values...

But how do you calculate one of those if you don't have the other yet?

I assume time or speed will be calculated from dbc data, but can't figure anything that relates dbc data to packet captures' time or speedz.

Does anyone have packets from other spells with trajectory splineflag?

Any news on this and where can I find a patch?

Was correctly fixed in [11720] + [11754] with SilverIce's awesome spline system. Thanks for your work though - I am sure it helped SilverIce
