[solved] what does dvy dvx mean help(please remove this to the solved problems place)

[Dominate]

Dvx: How much your char/ball/object goes forward
Dvy: How much your char/ball/object goes up/down
Dvz: well this isn't much used (atleast at your level) so don't mind about it.
Example:
In davis_ball.dat there's this kinda frame:

<frame> 0 flying
pic: 0 state: 3000 wait: 1 next: 1 dvx: 4 dvy: 0 centerx: 56 centery: 24 hit_a: 0 hit_d: 0 hit_j: 0
itr:
kind: 0 x: 26 y: 12 w: 45 h: 24 dvx: 7 fall: 20 arest: 6 bdefend: 10 injury: 30
itr_end:
bdy:
kind: 0 x: 26 y: 12 w: 45 h: 24
bdy_end:
<frame_end>

dvx: 4 means that it goes straight at kinda slow speed.
dvy: 0 means that it doesn't go up or down, just straight.
Later in the same .dat there's this kinda frame:

<frame> 8 flying
pic: 8 state: 3000 wait: 1 next: 9 dvx: 20 dvy: 0 centerx: 55 centery: 24 hit_a: 0 hit_d: 0 hit_j: 0
itr:
kind: 0 x: 26 y: 12 w: 45 h: 24 dvx: 7 fall: 20 arest: 6 bdefend: 10 injury: 30
itr_end:
bdy:
kind: 0 x: 26 y: 12 w: 45 h: 24
bdy_end:
<frame_end>

dvx: 20 means that now the ball goes at high speed.
dvx: 0 means that the ball still doesn't go up/down, only straight.

If still didn't help, i suggest you to just switch those values like dvx: 5 to dvx: 50 and dvx: 0 to dvx: 20 and see what happens, that helps you understand what those values do really mean.

thanks a lot and can we make a ball chase the player with dvx dvy dvz
