Flak Turrets implementation

Why485

I originally had that exact same issue you are describing robocop. But after much tweaking and unexpected side effects, the flak code that I posted works flawlessly for me. I have not had a single stuck flak bullet in a very, very long time.

robocop

Yeah, I’m using your code and finding the problems fixed. Thanks much.

Do you remember the formula offhand on how to figure out range of missiles? I know the muzzle velocity, lifetime of the motor, and the lifetime of the munition all factor in, but I don’t remember the details.

Well, classical physics should work fine normally

RANGE = MUZZLE_VELOCITY * LIFETIME + (ACCELERATION * MOTOR_LIFETIME ^ 2) / 2 + (MUZZLE_VELOCITY + ACCELERATION * MOTOR_LIFETIME) * (LIFETIME - MOTOR_LIFETIME)

That should work, although it may be possible to simplify it a bit ;D

I don’t know why, but i don’t get this effect to work. I wanted to modify the Battleship Flaks already implemented in the discovery mod, because they aren’t realy flakguns in my eyes. So i placed the gf_explosion_super_flak.ale in the fx/explosions folder and modified the entry in weapon_equip:

[Motor]
nickname = li_battleship_flak_turret01_motor
lifetime = 1
accel = 500
delay = 0

[Explosion]
nickname = li_battleship_flak_turret01_explosion
effect = li_flakcannon01_impact
lifetime = 0.000000, 0.000000
process = disappear
strength = 0
radius = 250
hull_damage = 750
energy_damage = 0
impulse = 50

[Munition]
nickname = li_battleship_flak_turret01_ammo
ids_name = 263383
explosion_arch = li_battleship_flak_turret01_explosion
hp_type = hp_gun
requires_ammo = false
hit_pts = 1000000
one_shot_sound = null
detonation_dist = 75
lifetime = 1
Motor = li_battleship_flak_turret01_motor
force_gun_ori = false
const_effect = li_flakcannon01_proj
HP_trail_parent = HPExhaust
seeker = DUMB
time_to_lock = 0
DA_archetype = equipment\models\torpedoes\ge_torpedo.3db
material_library = equipment\models\ge_equip.mat
mass = 200
volume = 0.000100

[Gun]
nickname = li_battleship_flak_turret01
ids_name = 263383
ids_info = 264383
DA_archetype = equipment\models\turret\li_turret04.cmp
material_library = equipment\models\li_turret.mat
HP_child = HPConnect
hit_pts = 25000
explosion_resistance = 0.1
debris_type = debris_turret_small
parent_impulse = 0
child_impulse = 0
volume = 16.000000
mass = 10
hp_gun_type = hp_turret_special_10
damage_per_fire = 0
power_usage = 170
refire_delay = 0.5
muzzle_velocity = 500
toughness = 10
light_anim = l_gun01_flash
projectile_archetype = li_battleship_flak_turret01_ammo
separation_explosion = sever_debris
auto_turret = true
turn_rate = 1000
lootable = true
dispersion_angle = 18

the effects_explosion:

[Effect]
nickname = li_flakcannon01_impact
effect_type = EFT_EXPLOSION_SHIP
vis_effect = gf_explosion_super_flak
;snd_effect = med_explosion1
snd_effect = flak_explosion_sound
lgt_effect = elite_flash_to_red
lgt_range_scale = 30
lgt_radius = 30

and the explosions_ale

[VisEffect]
nickname = gf_explosion_super_flak
alchemy = fx\explosions\gf_explosion_super_flak.ale
effect_crc = 290209852
textures = fx\sarma.txm
textures = fx\lightbeam.txm
textures = fx\standardeffects.txm
textures = fx\kioncannon.txm

The weapon has the new values, but the effect is just one small explosion, like it was before.

w0dk4

the effect is only one explosion, so there is nothing wrong there

use disperison_angle (or similar, cannot remember right now) and multiple fire hps to get a decent looking flak-explosion-screen

FR

Might want to try

dispersion_angle = ……

and maybe

DA_archetype = equipment\models\weapons\br_auto_shotgun.cmp
material_library = equipment\models\br_equip.mat

which will give you a gun with 5 HpFire.

I have used dispersion_angel (last line in weapon_equip). But i can’t use another archetyp, because it is a optional modification. Or am i wrong, that the archetyp have to be the same for the people without the mod and those, which have the mod?

FR

…… i suppose both (archetype + dispersion) have 2 be on the client
and should be on the server 2.

Hit detection is usually done on the client (w0dk4 is the man 2 ask )
and dispersion effects that.

It’s a funny thing 4 ‘2nd hand weapons’ ;D
and 2.5 make it hard 2 hit anything.

Aeril

The mod will be on the server, but it must be an optional mod for the client, so i can’t use different archetyps. Robocop said on the last page, that he got it to work with Why485’s code, so i used it, too.

OPR8R

hit detection is done on client AND on the server side

it simply depends on which kind of hit detection you mean coz there are different kinds

Aeril

I don’t mean any hit detection. I am wondering, why i see just one explosion, while i used the same code as Why485. This is, what i asked for.

FR

@Aeril:

I don’t mean any hit detection ……

… so dispersion and the numbers of HpFire effect that,
that was just an argument,
if you might need those changes client and/or server side.
