[help] car script speed

i got this script that makes them play a car gani. but how do i make it so they go fast when they in the car??? and its a spy car it shoots bullets :)

PHP Code:


		
			
//#CLIENTSIDE
if (weaponfired) {
  replaceani idle,dg_car;
  replaceani walk,dg_car;
  setani dg_car,;
  freezeplayer .1;
  setani dg_car,;
  this.angle=getangle(vecx(playerdir),vecy(playerdir));
  this.x=playerx+vecx(playerdir)*2;
  this.y=(playery-.5)+vecy(playerdir)*2.5;
 shoot this.x,this.y,playerz,this.angle+random(this.maxangle*5,this.maxangle),
    1,0,dg_bullet,1;

  triggeraction this.x,this.y,shot,;
}
if (keypressed && strequals(#p(1),s)) {
replaceani idle,idle;
replaceani walk,walk;
}

and dg stands for dev gulthex

Freeze the player and update their position manually.

Dude, please try and use GS2 :(

how do i freeze my player and update there possition???

.... HR? Skyld? Can I? Pleeeeeaaaaasseee?

If the stuff on the wiki doesn't help you, get a scripter.

i have 1 so he is not on

abd can ya help me with the script????

You can prevent the current player from moving using freezeplayer(t), where t is the amount of time the effect should last.

As for position, Graal uses the two-dimensional Cartesian coordinate system to describe positions as points in the Euclidean space.

The following image visualizes this in a clear manner.

You can translate an object thusly:
(x, y) -> (x + dx, y + dy)

Conversely:
x' = x + dx
y' = y + dy

To rotate about the origin:

Or:
x' = x * cos(theta) - y * sin(theta)
y' = -x * sin(theta) + y * cos(theta)

Please elaborate. I just researched and wrote a post for you, what else can I do? I'm not going to rewrite it over and over again until I accidentally get it right.

Read the guides on the Wiki. Read Twinny's guide. Find someone to help you learn to script. Look at Code Gallery posts.

Just please don't come on the forums, ask for scripts, then act like a jackass.

wurd.

And also, GS2 is like New English, it can be manipulated to do a lot of things. GS1 is like Old English, it can't really be said well off the top of your head anymore and can't be changed.

This type of mathematics is quite difficult to understand at first, but it will get easier. For the purposes of this script, I will be using Trigonometry to get the appropriate answer.

Say we have angle a and speed s, and we wanted to get the changing X and the changing Y values for said speeds.

For these purposes, I will assign the following values to a and s.

PHP Code:

From this, we can work out what the changing X and changing Y are.

First off, we want to convert a into radians so that they will work with Sine and Cosine. This is done using the following formula*:

PHP Code:


		
			
r = a * pi / 180

Now that we have the radian value of the angle (now referred to as r), we can continue on.

To get a simple speed (if s was 1, for example), you would use the following formula:

PHP Code:


		
			
changeX = sin(r)
changeY = -cos(r)

Now, if you wanted to alter the speed to the value specified in s, simply multiply it in the formula. You end up with the following:

PHP Code:


		
			
changeX = sin(r) * s
changeY = -cos(r) * s

From this, you will be able to get your new position using the speed specified. To do this, simply add it to your object's X and Y values, like so:

PHP Code:


		
			
x += changeX
y += changeY

Now, you may only want your object to move in 4 ways or in 8 ways, or even up to an infinite amount of ways. If you wish to put directional restrictions on your object, do the following before converting to radians:

PHP Code:


		
			
// This is for a 4-way movement.
a -= (a mod** 90)

// This is for an 8-way movement
a -= (a mod** 45)

Hope this was helpful :)

(NOTE: With the values specified, if you followed instructions carefully enough, you should get changeX = 0 and changeY = 5.)

* In GraalScript, this functionality is built-in. You can either use the formula or use degtorad(float) to get your answer.
** Replace this with a percent sign in GraalScript.

I think this is a little too complicated for him to understand.

Just use radians for your angle. Degrees is seldom used in programming.

PHP Code:


		
			
a = pi * 2 / 2; // 180 degree angle
// Of course, in this case, you can just use pi

To turn 4 directions:

PHP Code:


		
			
a += pi / 2;

To turn 8 directions:

PHP Code:


		
			
a += pi / 4;

GS1 is my favorite language ^^
