Unexpected token error? _pos

Programming Questions

Could somebody please point out where I am going wrong with this code? I tried to merge two together, but wasn't so successful (obviously, since I wouldn't be here).

This is pretty urgent and I am pulling my hair out over this - I feel as though I am so close, yet so far...

Please help!

float[] kaleidoscope_y= new float[kaleidoscope_num]; //y value

Re: Unexpected token error? _pos

    _pos.x = new PVector;
    _pos.y = new PVector;
Even with you have no parameters, you need parentheses:
    _pos.x = new PVector();
    _pos.y = new PVector();

Actually, this looks suspicious... I guess you intent _pos to be a PVector and to use its x and y parameters. Indeed, the declarations
PVector _pos.x;
PVector _pos.y;
are incorrect, you cannot have a dot in a variable. I guess you want:
PVector _pos;
then
_pos = new PVector();
which is confirmed by the usage you make of this variable.

You also have to classes HealthyCell, and no kaleidoscope which is expected at the start.

Cheers for that! Fixed the _pos error.

If the kaleidoscope is a function within a class, do I need a separate class or do I need to declare it in a different way?

You can call it like: health.kaleidoscope();
Of course, then, you have to change all occurences of kaleidoscope as class by something else.
