Hi! Ich würde gerne folgenden Partikeleffekt realisieren: Eiskristall Partikeleffekt (YouTube)Partikel in Kreisbewegung und negativer z-achse ist kein Problem, aber dieses exponentiale, das es aussieht wie eine Kugel. Hat da jemand nen Codeschnipsel oder kann mir da weiterhelfen?

Hat da echt keiner ne Ahnung?? Ich habs schon mit cos und sin versucht. Die Alternative wäre eine unsichtbare Kugel mit einer animierten Textur, welche sich dann dreht, aber die Animation säh dann immer gleich aus und im Video kann man ganz klar erkennen, das die Bewegung der einzelnen Partikel zufällig verläuft.

Here is what I have:
var radius = 5;
function remove_bees(PARTICLE *p)
{
p->vel_x = actor.x - (radius * sin(p.lifespan)*cos(p.lifespan));
p->vel_y = actor.y + (radius * sin(p.lifespan)*sin(p.lifespan));
p->vel_z = radius * cos(p.lifespan);
p.lifespan -= 10 * time_step;
}
function swarm_init(PARTICLE *p)
{
p.lifespan = 360;
p.alpha = 100;
p.bmap = snow_map;
p.size = 2;
p.flags = MOVE;
p.event = remove_bees;
}
function swarm()
{
while(actor == NULL) {wait (1);}
while (1)
{
effect(swarm_init, 1, vector(actor.x, actor.y, actor.z+45), normal);
wait(3);
}
}
But it looks like this:  Any ideas?

Hallo
Versuch es mal damit wahrscheinlich hast du das gemeint.
function keep_particle(PARTICLE *p)
{
p.lifespan = 100; // use a big value here
}
function particle_effect(PARTICLE *p)
{
// p.bmap = particle_tga;
p.size = 2; // gives the size of the particles
p.flags |= BRIGHT ;
p.event = keep_particle;
}
action sphere() // attach this action to a sphere model
{
set (my, PASSABLE | INVISIBLE );
var particle_pos[3];
while (my.skill1 < ent_vertices (my))
{
my.skill1 += 1;
vec_for_vertex(particle_pos, my, my.skill1);
// wait(-0.001);
effect(particle_effect, 1, particle_pos, nullvector);
}
}

Im sure you want to use cosv, sinv, tanv in degree and not radians  Oh, yes you're right! But it still looks like everything and not the way it should be
