Small Movement Script
 

I started working on a movement script which lets you steer using the left/right keys and accelerate with up/down.
It's meant for underwater/swimming movement.
Do you people think that it's usable, or should I change it's behaviour?

NPC Code:

---

//#CLIENTSIDE

if (created) {

  this.playerdir = 1;

  timeout = 0.05;

}

if (timeout) {

  disabledefmovement;

  // Steering left/right

    // Changing the dir

  if (keydown(1)) this.playerdir += 0.05;

  if (keydown(3)) this.playerdir -= 0.05;

  this.playerdir = this.playerdir%2;

    // Calculating the actual angle

  angle = 3.14159265 * this.playerdir;

    // Displaying the current direction

  showimg 0,@tempus sans itc@cb@X,playerx+1.5+xmove,playery+2+ymove;

  // Accelerating

    // Calculating current direction

  xmove = sin(angle);

  ymove = cos(angle);

    // Adding speed into a direction

  if (keydown(0)) {

    this.xspeed += xmove/5;

    this.yspeed += ymove/5;

  }

  if (keydown(2)) {

    this.xspeed -= xmove/20;

    this.yspeed -= ymove/20;

  }

    // Limiting the speed

  if (this.xspeed>0.5) this.xspeed = 0.5;

  if (this.yspeed>0.5) this.yspeed = 0.5;

  if (this.xspeed<-0.5) this.xspeed = -0.5;

  if (this.yspeed<-0.5) this.yspeed = -0.5;

    // Moving the player

  playerx += this.xspeed;

  playery += this.yspeed;

    // Slowing down a bit

  this.xspeed *= 0.99;

  this.yspeed *= 0.99;

    // Displaying the speed

  setplayerprop #c,#v(this.xspeed) #v(this.yspeed);

  timeout = 0.05;

}

sorry for double posting lol...it looks good though i just took a quick look at it

i could use help with movement in my c++ game o.O

Did anyone else noticed the angle is equal to 'pi'

Radians are neat yes? ;)

ya

Although it takes a bit of getting used to, it's pretty good. It strikes me as being kinda like the GTA1/2 motion system.

i notcied the PI thing also

:) thought it was just me

You seem to have a problem you need to take care of......before you end up in trouble....

o yeah, i thought i fixed that Xx

good boy ;)

pi is 3.14 etc. in math terms, not 180 degrees.

yeah :) well its pi both ways
