Math Help

I am finishing up an inventory script, but I need help for one part which is dropping an item. I want to make it so when the mousescreenx and mousescreeny variable is near the player another function begins. I'm not sure but I remember on an old script with it having something to do with %4 or something im not sure.

Help is appreciated, Thanks.

Why not use mousex and mousey instead of mousescreenx?

Then you can compare mousex to player.x directly.

Because it is an inventory z.z. The items are not on the gmap they are on the screen

But if your mouse is dragging it, the mouse has a position on the screen AND on the board.

The mouse is just making a duplicate image on the screen. It's still using the mousescreenx/y var. Also I need to make it so if the mouse is in front of the player the player.dir changes to down, or if its right, the player.dir changes to right. I think thats where I got the %4 from

PHP Code:


		
			
player.dir = getdir(mousex-player.x,mousey-player.y);

Oh no, mousex variable! Unthinkable.

I forgot that function existed, lol thanks. Now that thats done I realized another problem z.z.

Well im using a custom ItemLib with item IDs. {1-10 for currency, 200's guns, etc..}

PHP Code:


		
			
for (this.i: getstringkeys("clientr.item_")){

Is what I am using, the problem is that. The script puts the item by the id number. For example I have "Dollar" as item_1. The script puts that in the first slot, I have no item_2 but I have item_3 as "Cent", so the script skips the next slot and puts it in the third one. I cant even see my gun which has an id of 240. Is it the way I'm using for();?

Perhaps, I'm pretty sure the token before ":" is made to be a local variable, so I don't know what naming it this.- would do.

Even without the this.- its the same problem.

HTML Code:

//#CLIENTSIDE

function onCreated()

{

  this.onTimeout();

}

function onTimeout()

{

  if (mousex in |player.x - 5, player.x + 5| && mousey in |player.y - 5, player.y + 5|)

  {

    //Do Direction...and drop effect

  }

  showimg(200, this.curImage, mousescreenx, mousescreeny);

  changeimgvis(200, 3);

}

mousescreen- and player.- position are using a different kind of coordinates.

It should be mousex-player.x in |-5,5| blah blah blah

Even better is

PHP Code:


		
			
if (((mousex-player.x)^2+(mousey-player.y)^2)^.5 < 5) {
  // do stuffs
}

I should edit my post for mousex, not mousescreenx.

Yeah, I didn't mean it needed to be exactly as I wrote it. That's merely my preference.

Yeah, I prefer your way personally, as it looks more structured. :)
