Basic Concept for Weapons:
There is one or multiple Lua vms running, each with a lua file containing functions that describe the effects for all
weapons. The fx function in the code will call their corresponding Lua functions which will then create the effect.
FX functions to be implemented in Lua:
void CG_BUbbleTrail(vec3_t start, vec3_t end, float spacing)
localEnt *CG_SMokePuff(const vec3_t p, const vec3_t vel,
float radius,
float r, float g, float b, float a,
float duration,
int startTime,
int leFlags,
qhandle shader)
void CG_spawnEffect(vec3_t origin, refEnt *legs, refEnt *torso,
refEnt *head)
void CG_QFlashEvent(vec3_t org)
localEnt *CG_MakeExplosion( vec3_t origin, vec3_t dir,
qhandle hModel, qhandle shader,
int msec, float scale, qboolean isSprite)
localEnt *CG_MakeExplosion2( vec3_t origin, vec3_t dir,
qhandle hModel, int numFrames, qHandle shader
int msec, qboolean isSprite, float scale, int flags)
void CG_ExplosionEffects( vec3_t origin, int intensity, int radius)
void CG_Smoke( vec3_t position, vec3_t dir, int killTime, int radius )
void CG_Fire( vec3_t position, vec3_t direction, int killTime, int radius, int fxEnt )
void FXE_Spray (vec3_t direction, float speed, float variation, float cone, vec3_t velocity)
localEntity_t *FX_AddLine(vec3_t start, vec3_t end, float stScale, float scale, float dscale, float startalpha, float endalpha, float killTime, qhandle_t shader)
localEntity_t *FX_AddLine2(vec3_t start, vec3_t end, float stScale, float width1, float dwidth1, float width2, float dwidth2,
float startalpha, float endalpha, vec3_t startRGB, vec3_t endRGB, float killTime, qhandle_t shader)
localEntity_t *FX_AddOrientedLine(vec3_t start, vec3_t end, vec3_t normal, float stScale, float scale,
float dscale, float startalpha, float endalpha, float killTime, qhandle_t shader)
localEntity_t *FX_AddTrail( vec3_t origin, vec3_t velocity, qboolean gravity, float length, float dlength,
float scale, float dscale, float startalpha, float endalpha,
float elasticity, float killTime, qhandle_t shader)

float scale, float dscale, float startalpha, float endalpha, vec3_t startRGB, vec3_t endRGB,
float elasticity, float killTime, qhandle_t shader)
localEntity_t *FX_AddSprite(vec3_t origin, vec3_t velocity, qboolean gravity, float scale, float dscale,
float startalpha, float endalpha, float roll, float elasticity,
float killTime, qhandle_t shader)
localEntity_t *FX_AddSprite2(vec3_t origin, vec3_t velocity, qboolean gravity, float scale, float dscale,
float startalpha, float endalpha, vec3_t startRGB, vec3_t endRGB, float roll, float elasticity,
float killTime, qhandle_t shader)
localEntity_t *FX_AddBezier(vec3_t start, vec3_t end, vec3_t cpoint1, vec3_t cpoint2, vec3_t cpointvel1, vec3_t cpointvel2,
vec3_t cpointacc1, vec3_t cpointacc2, float width, float killTime, qhandle_t shader)
localEntity_t *FX_AddQuad( vec3_t origin, vec3_t normal, float scale, float dscale,
float startalpha, float endalpha, float roll, float killTime, qhandle_t shader )
localEntity_t *FX_AddQuad2( vec3_t origin, vec3_t normal, float scale, float dscale, float startalpha, float endalpha,
vec3_t startRGB, vec3_t endRGB, float roll, float killTime, qhandle_t shader )
localEntity_t *FX_AddCylinder( vec3_t start,
vec3_t normal,
float height,
float dheight,

localEntity_t *FX_AddParticle( vec3_t origin, vec3_t velocity, qboolean gravity, float scale, float dscale,
float startalpha, float endalpha, float roll, float elasticity,
float killTime, qhandle_t shader, qboolean (*thinkFn)(localEntity_t *le) )
localEntity_t *FX_AddSpawner( vec3_t origin, vec3_t dir, vec3_t velocity, vec3_t user, qboolean gravity, int delay,
float variance, float killTime, qboolean (*thinkFn)(localEntity_t *le), int radius )
Weapon FX in Lua:
function AltCompressionAftereffect(local le)
local cyl;
local shader = *insert shader here*
local percentLife = 1.0 - (le.endTime() - cg.getTime()) * le.lifeRate();
local alpha = 0.6 - (0.6*percentLife);
local length = 20;
local vec2, dir2;
cyl = FX_AddCylinder( le.rentorigin(),
le.dataSpawnerDir(),
length,
0,
10,
210,
10+(30*percentLife),
210,
alpha,
15);
cyl.addFlags( *LEF_ONE_FRAME* );
qmath.VectorMA(le.rentorigin(), length*2.0, le.dataSpawnerDir(), vec2)
qmath.VectorScale(le.dataspawnerdir(), -1.0, dir2);
cyl = FX_AddCylinder( vec2,
dir2,
length,
0,
10,
210,
10+(30*percentLife),
alpha,
0.0,
500,
shader,
15);
cyl.addFlags( *LEF_ONE_FRAME* );
end
Possible drawbacks/problems:
Lua might be to slow ...
How to handle shaders (preventing multiple qhandles for one sahders)?
