Problem is that the NPC can slide through walls while chasing. Example: there is a wall between the player and NPC so the NPC is running at the wall, if there is a wall above it as well it can slide through it while still facing the direction of the player.

2

Which mode is the chasing mode?
Plus have you forgot to add turn() to mode 2?

If you can’t read it I don’t want your help.

Thing is, you’re only checking one tile, that’s pretty much a no go.

In pretty much any baddy I make, I have to resort to an onwall2 equivalent.
For example:

function getChunk(){//returns a XxY tile chunk reading based off character size
  this.waterCount = 0; this.wallCount = 0;
  for (this.c = 0; this.c < this.charSize[0]*this.charSize[1]; this.c++){
    this.cCheck = {this.checkC[0]+(this.c%this.charSize[0]),this.checkC[1]+int(this.c/this.charSize[0])};
    this.waterCount += onwater(this.cCheck[0],this.cCheck[1]);
    this.wallCount  += onwall(this.cCheck[0],this.cCheck[1]);
  }

  this.canMove = (this.wallCount == 0 && ((this.canSwim == false && this.waterCount == 0) || (this.canSwim == true && this.waterCount >= 0)));
}

Implement such a thing into your code and you’ve got yourself a fix.

Nerd

I suspected as much. Was just hoping that someone could think up a quick fix with what I have. xD I’ll just simulate onwall2 then. Thanks.

8

Tricxta, in your snippet, what is this.checkC?

9

An array holding on wall or on water check data

10

this.checkC is the top left of the tile coordinate block you’d like to check.

Thanks.
