NPC Path-Finding Help

Here's how Zodiac's baddy movement works. It doesn't move directly to the player in one step but instead takes it in strides of 0.5 seconds of movement at max.

PHP Code:

// Removed Zodiac Specific Code
function onPlayerEnters() {
  if (!this.on) {
    this.on = true;
    onTimeout();
  }
}

function onTimeout() {
  if (players.size() < 1) {
    this.on = false;
    return;
  }
  chase(players[0]);
}

function chase(target) {
  // Set Speed
  temp.speed = .3;
    
  // Calculate Position in front of Target
  temp.tpos = {target.x - vecx(this.dir)*2.5, target.y - vecy(this.dir)*2.5};
  // Calculate Distance to Target
  temp.dist = ((temp.tpos[0] - x)^2 + (temp.tpos[1] - y)^2)^.5;
  // Calculate Steps Required 
  temp.steps = temp.dist / temp.speed;
  // Avoid Too Many Steps
  if (temp.steps > 10)
    temp.steps = 10;

  // Calculate Angle towards Target
  // Random helps prevent clumping of npcs
  temp.angle = getangle(temp.tpos[0] - x, temp.tpos[1] - y) + random(-0.2,0.2);
  // Calculate the Delta
  temp.dx = cos(temp.angle) * temp.speed;
  temp.dy = -sin(temp.angle) * temp.speed;

  setcharani("walk", this.attr[2]);
  move(temp.dx * temp.steps, temp.dy * temp.steps, int(temp.steps) * .05, 8);

  setTimer(int(temp.steps) * .05);
}

function onMovementFinished() {
  setcharani("idle", "");
} 


Sure it still allows baddies to walk over walls but it's an even bigger issue when players can glitch them into corners and abuse the situation.
