Sinus and Cosinus

MattMrHat · #1 10-07-2002, 05:13 AM

About "Sin" and "Cos"..
They are used to make something move in circles. Replace (a) with a number, or something. I can't really understand the explanation written in the commands.rtf so I am asking for help simplifying how to use these.

I kinda needed to make an NPC that makes things go in circles. o.o

sin( a ) the sinus of a; a is an angle in the radiant system (0...3.14)

cos( a ) the cosinus of a; a is an angle in the radiant system (0...3.14)

I thought it was sine and cosine

It is. Maybe it's another way or he's "going Greek."

I ment why is he calling it Sinus and Cosinus, are those greek names like Amagius says they are?

Kai, I told you im not that far in math yet. How am I supposed to be able to understand that? Im only 15, im not in college yet.

I simply wanted to know how to make fire explosions go in a circle

I sortof understand that site, I'm 14 and I can make things go around easy enough, just learn how to manipulate radians, there are plenty of scripts posted around these forums that you can learn off of, dig em up, dont expect someone to just hand you the answer

I dont even understand anything on the page.. Its all too complicated! Why cant it be easy, like this.circle=true

Please explain how I would make explosions in a circle.. I will do it myself if I can understand how. I will fix your sig if you help me.

this.circle wouldnt make ANY sense, would it turn clockwise or counterclockwise, what would be the radius of the spin, how fast would it spin, and other things couldn't be decided just by saying this.circle = true, just stop being lazy and read scripts that use sin/cos, you will be much better off learning yourself, if someone just shows you it, you will never learn on your own, if you learn on your own, you have a much better chance to gain more knowlege and understanding

I thought it was 0.00 to 6.28 o.o

That's not true, because Nyght taught me how to do tokenize, and I fully understand how to do that. All he did was explain what it does and how to use it.

Plus there wouldn't just be this.circle,
there would be stuff like.
this.speed=
this.radius=
or whatever else, so it would all fit together.

Graal2001_NAT · #12 10-07-2002, 12:01 PM

still inefficent, much better thing could be implimented into the graal exe
and nyght probably explained it to you, which is different than just showing you an example

If that doesn't help then I can't help you.

...There wasn't even a script there that makes things go in a circle.. you just drew a picture of a circle and explained what I already knew from that link you gave in your first post. (sin=opposite/hypotuse or whatever)

Don't be upset with me because i'm new to this.. everyone was at some point.
