--- Introduction ---
This plugin adds new weapon to zombie plague - concussion grenade.I took
this idead from Team Fortress Classic.When grenade explodes it doesn't
do any damage, but it starts to make hallucinations to players, such as
screen shake, screen fade, recoil changes.
--- CVARs ---
zp_conc_nade_radius 500 -- Explosion radius
zp_conc_nade_duration 7 -- Duration of hallucinations
--- Credits ---
NiHiLaNTh - Plugin
dels/Shalun - Grenade model
MeRcyLeZZ - Some useful code parts
xPaw / Xellath - Code optimization
--- Changelog ---
v1.0 - Initial release
v1.1 - Optimized code ( Thanks xPaw and Xellath )
v1.2 - Fixed bug when after explosion player were not affected
v1.3 - Added p_ and w_ model support
- Fixed run-time error

Hello.
I want to increase the amplitude the screen is shaking at, but i don't know how.
I suspect this is the code i have to modify:
PHP Code:
// Make a screen shake
message_begin ( MSG_ONE_UNRELIABLE, g_msgScreenShake, {0,0,0}, ID_AFFECT )
write_short ( 0xFFFF ) // Amplitude
write_short ( 1<<13 ) // Duration
write_short ( 0xFFFF ) // Frequency
message_end ( )
However, i don't understand the values and i don't know how to change them.
If i want to increase or decrease the amplitude and the frequency, what do i have to replace "0xFFFF" with? What is this "FFFF" supposed to mean? Is it a value? Are there other letters that can increase or decrease the amplitude? I expected the value to consist of numbers, not letters.
Can someone explain to me how to increase or decrease the values?
