Draw point with time function
I try to write a script to draw cloud-point. The script must draw a single point every second from an array (or or a time that I decide). I try to use Time (or delta.Time) function (I search inside forum without result) without result. I don't understand it'work... This is the script:
var dotMaterial : Material;
var PointsList : Array;
var Points : Array;
var PointsArray : Vector3[];
var dotSize = 1.0;
var dotsnumber = 1;
var dotstime = 1;
private var oldPosition : Vector3;
private var oldRotation : Quaternion;
private var cam : Transform;
private var dots : VectorPoints;
PointsList = [];
function Start() {
cam = Camera.main.transform;
oldPosition = cam.position;
oldRotation = cam.rotation;
Points = new Array();
for (i = 0; i < PointsList.length / 3; i++){
Points.Add(Vector3(-PointsList[i*3],PointsList[i*3+2],-PointsList[i*3+1]));
}
PointsArray = Points.ToBuiltin(Vector3);
dots = new VectorPoints("Dots", PointsArray, null, dotMaterial, dotSize);
dots.maxDrawIndex = dotsnumber; //this value say how many point of array drawing
Vector.DrawPoints(dots);
}
function Update() { // every second script must be draw one more point
dotstime = Time.deltaTime*1;
dotsnumber = dotsnumber + dotstime;
}
function LateUpdate () {
if (cam.position != oldPosition || cam.rotation != oldRotation) {
oldPosition = cam.position;
oldRotation = cam.rotation;
dots.maxDrawIndex = dotsnumber;
Vector.DrawPoints(dots);
}
}
Thanks. The script work, but I have a problem. The frame rate drops over time! Help... This is the new script:
var dot$$anonymous$$aterial : $$anonymous$$aterial;
var PointsList : Array;
var Points : Array;
var PointsArray : Vector3[];
var dotSize = 1.0;
private var oldPosition : Vector3;
private var oldRotation : Quaternion;
private var cam : Transform;
private var dots : VectorPoints;
PointsList = []; //15000 point coordinate max.
var dotsnumber = 1;
function Start() {
InvokeRepeating ("IncreaseDotsnumber", 0.01, 0.01);
Points = new Array();
for (i = 0; i < PointsList.length / 3; i++){
Points.Add(Vector3(-PointsList[i*3],PointsList[i*3+2],-PointsList[i*3+1]));
}
RandomizeArray.RandomizeArray (Points);
PointsArray = Points.ToBuiltin(Vector3);
dots = new VectorPoints("Dots", PointsArray, null, dot$$anonymous$$aterial, dotSize);
cam = Camera.main.transform;
oldPosition = cam.position;
oldRotation = cam.rotation;
}
function IncreaseDotsnumber(){
dotsnumber++;
}
function LateUpdate () {
if (cam.position == oldPosition || cam.rotation == oldRotation){
dots.maxDrawIndex = dotsnumber;
Vector.DrawPoints(dots);
}
else if (cam.position != oldPosition || cam.rotation != oldRotation) {
oldPosition = cam.position;
oldRotation = cam.rotation;
dots.maxDrawIndex = dotsnumber;
Vector.DrawPoints(dots);
}
}
Please don't post comments as answers. It's expected that the framerate would go down over time, since you're drawing more and more of the points over time.
Sorry. It was a question related to the first and I did not want to open another post. Any idea to solve the problem?
"dotstime" is an int, so assigning Time.deltaTime to it will always result in 0. You're better off just using InvokeRepeating anyway.
function Start () {
InvokeRepeating ("IncreaseDotsnumber", 1.0, 1.0);
}
function IncreaseDotsnumber () {
dotsnumber++;
}
