attract particles
Can someone translate the following piece of code into Javascript please? I realise that parts of it is already in Javascript. The only lines that my version of the Unity3D has problems with are the following:
particles[i].position = Vector3.Lerp(particles[i].position; transform.position; Time.deltaTime / 2.0f); //On Line 14
&
for (var i:int = 0; i < particles.GetUpperBound(0)){ //On Line 12
Here's all of the script together:
var p:ParticleEmitter; var particles:Particle[];
function Start() { p = (ParticleEmitter)(GameObject.Find("Magical Fire Smoke").GetComponent(typeof(ParticleEmitter))); particles = p.particles; }
function Update() { for (var i:int = 0; i < particles.GetUpperBound(0)) { particles[i].position = Vector3.Lerp(particles[i].position; transform.position; Time.deltaTime / 2.0f); } p.particles = particles; } This piece of code was taken from:

Get rid of the semicolons inside the vector3 of this line and see if that helps ->
particles[i].position = Vector3.Lerp(particles[i].position; transform.position; Time.deltaTime / 2.0f); //On Line 14
change it to ->
particles[i].position = Vector3.Lerp(particles[i].position, transform.position, Time.deltaTime / 2.0f) ;
I've changed what you recommended and it is still co$$anonymous$$g up with two errors. Here's the updated script:
var p:ParticleEmitter;
var particles:Particle[];
function Start() {
p = (ParticleEmitter)(GameObject.Find("$$anonymous$$agical Fire Smoke").GetComponent(typeof(ParticleEmitter)));
particles = p.particles;
}
function Update() {
var i = 0;
for (i = 0; i < particles.GetUpperBound(0))
{
particles[i].position = Vector3.Lerp(particles[i].position; transform.position; Time.deltaTime / 2.0f);
}
p.particles = particles;
}
The lines that it is highlighting are:
for (i = 0; i < particles.GetUpperBound(0)) //Line 12
The error message for this is:
BCE0044: expecting ;, found ')'
The lines that it is highlighting are:
particles[i].position = Vector3.Lerp(particles[i].position; transform.position; Time.deltaTime / 2.0f);//Line 14
The error message for this is:
BCE0044: expecting :, found '='.
Ok, here's the whole script from the 2nd link you posted up there, converted to javascript.
#pragma strict
public var p : ParticleEmitter ;
public var particles : Particle[] ;
public var affectDistance : float ;
var sqrDist : float ;
var thisTransform : Transform ;
function Start(){
thisTransform = transform ;
p = GameObject.Find("StrangeParticles").GetComponent(ParticleEmitter) ;
particles = p.particles ;
sqrDist = affectDistance * affectDistance ;
}
function Update(){
var dist : float ;
for(var i=0 ; i < particles.GetUpperBound(0) ; i++){
dist = Vector3.SqrMagnitude(thisTransform.position - particles[i].position) ;
if(dist < sqrDist){
particles[i].position = Vector3.Lerp(particles[i].position, thisTransform.position, Time.deltaTime / 2) ;
}
}
p.particles = particles ;
}
I'm new to C# also, haven't even bothered reading any of it until the passed week of being on this site, hopefully the conversion is right and it works for you.
I still think one of the main problems is you putting semicolons inside the Vector3 ...if you notice on both of your posts about updating your script, the semicolons are still there.
Then another problem is probably the "p" variable being
p = (ParticleEmitter)(GameObject.Find("$$anonymous$$agical Fire Smoke").GetComponent(typeof(ParticleEmitter)));
when it should probably be
p = GameObject.Find("$$anonymous$$agical Fire Smoke").GetComponent(ParticleEmitter) ;
I could be wrong about that "p" variable, I'm not sure. Didn't test any of it to see.
