this.radius, etc.
 

Ok I know this is a n00b question, but here goes:
How do you just have something move in a circle repeatedly? I hardly ever need it, but when I do, I get mad that I haven't learned it. I know it uses stuff like this.radius, but I forgot how...

this.radius is just a made up var..
you dont really need it . I personally use it just to say how far from the player. here is a little code for money that goes in a circle with adding radius(called spiraladd if u notice)..

NPC Code:

---

//npc made by LiquidIce

if (playertouchsme) {

toweapons Spiral Gold;

}



if (weaponfired) {

this.angle=0;

this.radius = 3;

this.spiraladd = 0;

 while (this.angle<10) {

 this.x=sin(this.angle);

 this.y=cos(this.angle);

 this.x*=(this.radius+this.spiraladd);

 this.y*=(this.radius+this.spiraladd);

 this.x+=(playerx);

 this.y+=(playery);

 lay2 goldrupee,this.x,this.y;

 this.angle+=.2;

 this.spiraladd+=.2;

 sleep .01;

 }

}

NPC Code:

---

if (playerenters||timeout) {

  timeout = .05;

  this.radius = 10;

  this.angle+=.314;

  this.x = x+sin(this.angle)*this.radius;

  this.y = y+cos(this.angle)*this.radius;

  showimg 0,@Arial@@hi friend,this.x,this.y;

}

I suggest you reset the angle every circle it does , else in minutes it will be a HUGEEEEEEEEEEEEEE variable.

and forgot here is the code

NPC Code:

---

if (playerenters||timeout) {

timeout = .05;

this.radius = 10;

this.angle+=.314;

if (this.angle>6.28) { this.angle=.314; }

this.x = x+sin(this.angle)*this.radius;

this.y = y+cos(this.angle)*this.radius;

showimg 0,@Arial@@hi friend,this.x,this.y;

}

---

Thanks!

Jadis:

It does not matter

well if i idle in your level for a bit the variable gets hugeeeeee
it matters =(

this.angle=this.angle%6.28
:rolleyes:

liek lol . i aint a math magician . im used to if .. but yeah u can just use MOD..
but it would be
this.angle=(this.angle+.324)%6.28;

Jadis:

you said .324!!!!!!!!!!!!!!!!!

.314 or .324 .. who cares =)

Actually in Graal you can just use mod.
