SPTransporterLensFlares

TiM: Judging from the title,
|
|
you just KNOW it's mine ;)
|
|
|
|
Anyway, the point of this
|
|
function is to render 4
|
|
sprites and then scale + move
|
|
them in a way reminisicant
|
|
of ST: Voyager's transporter FX.
|
|
|
|
I wrote this instead of using the
|
|
already made FX spawning functions
|
|
because they don't let u track an origin.
|
|
To stop the particle
|
|
from rendering within the character, I'm going to
|
|
use the DEPTHHACK renderflag, the flag
|
|
originally used for the weapon models
|
|
in first-person mode. :)
|
|
|
|
Planned timing:
|
|
|
|
0 - 500 : Flare spawns, and scales up to it's main size (width parameter)
|
|
500 - 1500 : Flare moves up the height/2 of model (height parameter)
|
|
1500 - 2000 : Flare scales down and disappears ( width * 1.0 - (timeScale) )
|
