Problem with copying array that holds Raycasthit objects
Posted: Fri May 14, 2010 2:34 pm Post subject: Copying an array
it doesn't seem to work...
here is how i tried to do it:
declaration
var hitObjects : Collider[];
var hits : RaycastHit[];
copying the array after some objects were hit:
Code:
for (i=0;i<hits.length;i++) {
hitObjects[i] = hits[i].collider;
}
later on i wanted to verify is everything is ok with this in OnGUI function but i get info only for hits[x] not for anything else:
Code:
for(var x=0;x<hits.length;x++){ GUI.Label(Rect(10,10+((x+1)*15),400,30),hits[x].collider.name); }
for(var y=0;y<hitObjects.length;y++){ GUI.Label(Rect(10,40+((y+1)*15),400,30),hitObjects[y].name); }
Do a check, have you initialize the starting length for the hitObjects array?
After seeing comment: You have to use a Javascript Array, or an ArrayList, which supports dynamic size. You can take a look at this page
Or when using fixed size array
hitObjects = new hitObjects[hits.length];
no, i thought that it will automatically adjust the size according to the size of the array i am copying, how to do that?
It is only automatic when you add content to an array through the Inspector. In code, a normal array is not automatic. Look at the link above in the answer above for array lists and other types of collections that can resize on the fly.
