Custom Movement: Help Needed!

[scriptless]

Okay so what I have here lets me move fine altho it does not let me move flush against the wall.. and if walking between 2 wall tiles.. example: wall, non, non, wall u have to be perfectly in between the walls to move. Also only lets me move at speeds close to (16/16) i think.

Anyone have any suggestions on making movements twards a wall flush? And is there any way to output the collision points of a onwall2?

PHP Code:

//#CLIENTSIDE
function onCreated()
{
  this.enabled = true;
  setTimer(0.05);
  if ( this.enabled == true )
  {
    disabledefmovement;
  } else {
      enabledefmovement;
      }
}

function onTimeOut()
{
  this.speed = (8/16);

  for ( i=0; i < 4; i++ )
  {
    if ( keydown(i) )
    {

  temp.tw = ( abs(vecx( i )) == 1 ? 16 : 32 ) / 16;
  temp.th = ( abs(vecy( i )) == 1 ? 16 : 32 ) / 16;
  temp.aa = ( abs(vecy( i )) == 1 ? .5 : 0 );
  temp.tx = player.x + 1 + vecx( i ) * 1 - temp.aa;
  temp.ty = player.y + 1 + vecy( i ) * 1 + temp.aa;
    
      if ( player.ani != "walk" && player.ani != "swim") {
        setAni("walk", null);
      }

      if ( this.enabled == true )
      {
        player.dir = i;
        temp.nx = player.x + vecx(i)*this.speed;
        temp.ny = player.y + vecy(i)*this.speed;
        if ( !onwall2( temp.tx, temp.ty, temp.tw, temp.th ) ) {
          player.x = temp.nx;
          player.y = temp.ny;
        }
      }
    } else {
        if ( !keydown(0) && !keydown(1) && !keydown(2) && !keydown(3) ) {
          if ( !onwater( player.x, player.y ) ) {
            setAni("idle", null);
          }
        }
      }
  }

  if ( onwater( player.x, player.y ) ) {
    if ( player.ani != "swim" ) {
      setAni("swim", null);
    }
  }

  
  setTimer( 0.05 );
  
  // debug only
  showpoly(200,{temp.tx,temp.ty,temp.tx+temp.tw,temp.ty,temp.tx+temp.tw,temp.ty+temp.th,temp.tx,temp.ty+temp.th});
  changeimgcolors(200,1,0,0,.25); 
  
} 


Any help or suggestions appreciated.

PS: This is a rough draft. I know its sloppy but its readable non-the-less.

A common technique to 'close the gap' is usually running a loop like such :
for (temp.i=0;i<playerspeed;i+=1/16)
Then checking for an onwall from the player plus the vecx/y of the player's direction * i. If there is a wall, break the loop and add playerx += vecx(playerdir)*i and so on.

There are 2 positions my script checks so would I be using 2 onwall checks then instead of my onwall2? I didn't realise onwall2 used more CPU then onwall. So that will be something I need to change.

Meh, I used onwall2... I find it much more convenient to do two 16x16 onwall2 checks than 4 onwall checks, especially since you only need those two checks for sliding around corners.

Speeds close to 16/16? As in one?

If you mean something along the lines of speeds like x/16, that's fine, as 1/16 is one pixel in Graal coordinates.

[DustyPorViva]

I adjust my onwall2 to compensate for whatever speed the player is moving.

[12171217]

Doesn't that make the player stop further away from the wall..?

[DustyPorViva]

Not if you close the gap like I explained

[12171217]

Well I don't see the point of doing onwall2, as you can't have sliding collision then.

[DustyPorViva]

How so? I have sliding collision...
