Rotating?

[Knightmare1]

how do you rotate an image instead of having it 4 directions? for example, a car. is it like:

PHP Code:

if ( keydown( 1 ) )
{
  this.angle += .2;
} 


and how do you make it move in the direction by pressing up?

[Rapidwolve24]

Here are some snippets from one of my car scripts.

To move in direction of angle:

PHP Code:

temp.newx = player.x + (this.graalspeed * cos(this.angle));
temp.newy = player.y + (this.graalspeed * -sin(this.angle)); 


To accelerate:

PHP Code:

function Accelerate()
{
  this.smod = 0;
  this.speed += (this.speed < this.maxspeed) ? 0.20 : 0;
} 


Turns:

PHP Code:

function LeftTurn()
{
  this.angle += degtorad(this.turnpower);
    
  if (radtodeg(this.angle)+this.turnpower <= 0)
  {
    this.angle = degtorad(360);
  } 
  
    if (radtodeg(this.angle)+this.turnpower >= 360)
  {
    this.angle = degtorad(0);
  }
  
}

function RightTurn()
{
  this.angle -= degtorad(this.turnpower);
  
  if (radtodeg(this.angle)+this.turnpower >= 360)
  {
    this.angle = degtorad(359);
  } 
  
  if (radtodeg(this.angle)+this.turnpower <= 0)
  {
    this.angle = degtorad(360);
  }
    
} 


[Knightmare1]

well, ork made a car script that doesnt work, but it rotates the car. why wont it work?

PHP Code:

//#CLIENTSIDE
function onCreated() enabledefmovement();
function onPlayerChats()
{
  if (player.chat == "/car")
  {
    onCreated();
    this.car = !this.car;
    if (this.car) onTimeOut();
    if (!this.car) setTimer( 0 );
  }
}
function onTimeOut()
{
  disabledefmovement();
  showimg( 1, "ut_car-upd_up.gif", player.x, player.y );
  findimg( 1 ).rotation = this.ang;
  if ( keydown( 3 ) )
  {
    this.ang -= .1;
  }
  if ( keydown( 1 ) )
  {
    this.ang += .1;
  }
  if ( keydown( 0 ) )
  {
    player.x -= cos( this.ang ) * 1;
    player.y -= sin( this.ang ) * 1; 
  }
  setTimer( 0.05 );
} 


it shows the car, the car rotates, but it still goes the direction that your holding. (and it shows the charecter)

[napo_p2p]

I would normally set the player's gani and just send parameters to the gani to control the angle of the car (using a gani script). This effectively hides the players and makes sure that all other players can see the rotation of the car.

From my initial inspection, the only thing I can see that would be causing a movement issue is that you should do:

PHP Code:

player.x -= cos(this.ang) * 1; 


When I have more time, I'll take a further look at it. But, play around with it more and let us know if you have any success .

    if (this.car) onTimeOut();
    if (!this.car) setTimer( .5 );

  disabledefmovement();
  showimg( 1, "<image name>", player.x, player.y );

  if (radtodeg(this.angle)+this.turnpower <= 0)
  {
    this.angle = degtorad(360);
  }
  } 


Fixed it up and tried it, Works great. Have fun :]

[Chompy]

PHP Code:

player.x += cos(this.ang);
player.y -= sin(this.ang); 


:O
and this.ang should be between 0 and pi*2
(if you're not into trig you can just use degtorad() to convert radians to degrees (for example: degtorad(360); degtorad(145); etc.) )

it still doesnt work for me. i can make it go, but it still shows me walking in the direction and it is slow unless your going the up direction.

Seriously, all you did was copy and pasting Rapid's functions into the post..

If it worked for you, I'll bet if you remove that you pasted it will work, since you didn't edit the original script to use those functions..

[Jeffyy]

Ya... I did that and changed the buttons so up is go instead of left. I said i fixed it up, I didn't say I made it...

All he needed was to change a little minus to a plus, not some fancy functions ;o

Can you read... All I said was that "I FIXED IT UP A ABIT." There are no Fancy functions... I don't think.

[Jeffyy]

Uhh... You can adjust the script for how fast you want to go, And it does work. Log on Riot.

***** @ inability to see (Yes, Stephen's quote xD)

look at the bottom of your script o_o

[Chompy]

Originally Posted by Knightmare1

it goes slow because of:

PHP Code:

player.x -= cos( this.ang ) * 1;  // *1 isn't needed..
player.y += sin( this.ang ) * 1;  // *1 isn't needed

// why would you multiply something by 1..? 


try it around, for example

PHP Code:

player.x -= cos( this.ang ) * 3;
player.y += sin( this.ang ) * 3; 


or you can replace 3 with a variable for example named this.speed
and change that var based on how fast the car would drive..

[Knightmare1]

i found the problem. now, how do i make it so a player cant walk?

[napo_p2p]

disabledefmovement(); should normally do it, but I see that it is already in the script.
My guess is that there is a custom movement system that is interfering with the car script. You will probably need to disable that movement system while someone is in a car.

oooooo so remove the weapon? and it can go over walls!

[napo_p2p]

For testing, I guess you could remove the weapon. When it goes to players though, you could just have the movement system stop working when a car is on.

That script is able to go over walls because you need to add some onwall detection :P. I think you have the skills to play around with onwall detection yourself. If you hit a snag, you know where to ask .

You didn't read what I wrote to Jeffyy, did you?

[Knightmare1]

and now a new problem showed up, you can only see yourself rotate on your screen. you cant see anyone else rotate, and no one can see you rotate.

[Switch]

Doesn't the img index have to be like 200+ ??

Naw

(some very low negative number) to -1 are local (client only)
0 to 200 makes it so other players can see it
index 200 ++ up are local (client only)

It would be better if you make it a gani tho, or you can use Dusty's player effect function:

and set client.rotation to wanted rotation number

I haven't seen the image, but it would probably been only the left direction though, if you are going to rotate the player

[Knightmare1]

there is another car script i found, and it does gani, but it shows the car under you not rotating, but the direction is right. this was by chris.

Are you are using findImg(index).rotation = player.attr[5] somewhere in the Gani script? Also it is showing under the player because the visibility is too low (you should be hiding the player anyways). changeimgvis(index, 3) should work though.

i would put findImg(index).rotation = player.attr[5] just anywhere in the gani script?

Under where ever the showimg(..) is, and it also should be in a timeout.
Don't actually put index, replace it with whatever index your showimg() is.

You should be putting the showimg function in the gani script.

}
