Need some help..

[Kadar]

Im not so good at math so i cant figure this one out, here goes.

I am trying to make a npc that shoots a projectile towards the mousex and mousey, but i cant figure out how to get the angle to work.

Im trying to get the angle of mousex and mousey so the projectile will shoot towards the mouse position, i can figure out how to use power but i cant figure out the angle part, any help would be appreciated..

Thanks

getangle( dx,dy ) - the angle of vector (dx,dy) to the x coordinate (0...2*3.14)

Just subtract the player position with the mouse position.

I wish I could find the power..
I've tried all different equations and none of them work.

...
dx=mousex-playerx;
dy=mousey-playery;
angle=getangle(dx,dy);
btw u might want to change dx and dy so its from the center of the mouse and player but that's the concept =)

What I was going to say, what you did on Zion :]

and you could use the basic distance calculation to make the projectile land where you click

(((playerx-mousex)^2)+((playery-mousey)^2))^0.5

I think.

I'll try that and see if it works.

NPC Code:

---

if(created || timeout){

  distx = playerx - mousex;

  disty = playery - mousey;

  ang = getangle(distx,disty);

  showpoly 200,{playerx+1.5,playery+1.5,mousex,mousey;}

  message #v(ang);

  timeout = 0.05;

}

I'm phat.
